Your home’s heating installation Your home's heating installation The House Heating Curve The heating curve is the central part of the product’s control system. It is the heating curve which determines the compensated flow temperature requirements for your property dependent upon the outdoor temperatures. It is important that the heating curve is correctly adjusted, so that you achieve the best operation and economy possible. One property requires a radiator temperature of 30 °C when the outdoor temperature is 0 °C, whilst a different property requires 40 °C. The difference between different properties is determined by the radiator surface area, the number of radiators and how well insulated the house is. ! The set heating curve is always given priority. The room sensor can only increase or decrease the compensated flow temperature to a certain extent above the set heating curve. Where operating without a room sensor, the selected heating curve determines the flow temperature supplied to the radiators purely from the outside temperature reading. Adjustment of Default Values for the Heating Curve You define the heating curve yourself for your property by setting two values in the product control system. This is achieved by selecting the options Inclination or Adjustment under the Installer/Settings/Radiator system menu. Ask your installer to help you set these values. It is extremely important to set the heating curve and, in some cases, unfortunately, this process may take several weeks. The best way of doing this, upon the initial start-up, is to select operation without any room sensor. The system then operates using the outdoor temperature reading and the property’s heating curve only. During the adjustment period it is important that: • the night reduction function is not selected. • all thermostat valves on the radiators be fully opened. • the outdoor temperature is not higher than +5 °C. (If the outdoor temperature is higher when the system is installed, use the factory set curve until the outdoor temperature falls to a suitable level.) • the radiator system is operational and correctly adjusted between different circuits. Appropriate Default Values During installation you can seldom achieve a precise setting for the heating curve instantly. In this case, the values given below may provide a good starting point. Radiators with small heat-emission surfaces require a higher primary flow temperature. You can adjust the gradient (heating curve gradient) for your heating system under the Installer/Settings/Radiator system menu. Recommended values are: 8 Floor heating only Inclination 35 Low temperature system (well insulated houses) Inclination 40 Normal temperature system (factory setting) Inclination 50 High temperature system (older houses, small radiators, poorly insulated) Inclination 60 CTC EcoZenith i250 General Information Adjusting the heating curve The method described below can be used to adjust the heating curve correctly. Adjustment if it is too cold indoors • If the outdoor temperature is lower than 0 degrees: Increase the Inclination value by a couple of degrees. Wait 24 hours to see if any further adjustment is required. • If the outdoor temperature is higher than 0 degrees: Increase the Adjustment value by a couple of degrees. Wait 24 hours to see if any further adjustment is required. Adjustment if it is too warm indoors • If the outdoor temperature is lower than 0 degrees: Decrease the Inclination value by a couple of degrees. Wait 24 hours to see if any further adjustment is required. • If the outdoor temperature is higher than 0 degrees: Decrease the Adjustment value by a couple of degrees. Wait 24 hours to see if any further adjustment is required. ! If the values set are too low, this may mean that the desired room temperature is not being reached. You then need to adjust the heating curve, as necessary, following the method shown above. When the basic values have been set more or less correctly, the curve can be finely adjusted directly using the Room temp. shown on the home menu screen. Description of inclination and adjustment Inclination 50: The value set is the outgoing temperature of the water supplied to the radiators at an outdoor temperature of –15 °C, e.g. 50 °C. A lower value is selected where a radiator system has large radiator areas (a low temperature system). Floor heating systems require low temperatures. A low value should therefore be selected. The value must be increased for high temperature systems to achieve a high enough indoor temperature. Adjustment 0: The adjustment means that the flow temperature can be raised or lowered at a specific outdoor temperature. Adjustment 0 means 50 °C primary flow when the outside temperature is -15 °C. Adjustment -5 means 45 °C primary flow when the outside temperature is -15 °C. For example: Inclination 50 means that the temperature of the water supplied to the radiators will be 50 °C when the outdoor temperature is –15 °C (if adjustment is set to 0). If the adjustment is set to +5, the temperature will be 55 °C instead. The curve is increased by 5 °C at all temperatures, i.e. it is parallel displaced by 5 °C. CTC EcoZenith i250 9 General Information Examples of Heating Curves You can see in the diagram below how the heating curve changes with different Inclination settings. The gradient of the curve shows the temperatures that the radiators require at different outdoor temperatures. Primary Flow Temperature Curve Inclination The inclination value which is set is the primary flow temperature when the outside temperature is –15 °C. Outside Temperature Heating off, out Adjustment The curve can be parallel displaced (adjusted) by the desired number of degrees to adapt to different systems/ houses. Inclination 50 °C Adjustment +5 °C Primary Flow Temperature Inclination 50 °C Adjustment 0 °C Outside Temperature Heating off, out An example Inclination 60 °C Adjustment 0 °C Primary Flow Temperature In this example, the maximum outgoing primary flow temperature is set at 55 °C. The minimum permitted primary flow temperature is 27 °C (e.g. summer-time basement heating or the floor circuits in a bathroom). Outside Temperature Summer-time operation All properties have internal heat gains (lamps, oven, personal heat etc.), which means that the heating can be switched off when the outdoor temperature is lower than the desired room temperature. The better insulated the house is, the earlier the heating from the heat pump can be switched off. The example shows the product set at the default value of 18 °C. This Heating off value can be changed under the Installer/Settings/Radiator system menu. When the heat is switched off in this way, the radiator pump stops and the mixing valve is shut down. The heating starts up automatically when it is required again. Primary Flow Temperature Outside Temperature Heating off, out 10 CTC EcoZenith i250 General Information 2.

CTC EcoZenith i250 design The picture below shows the basic construction of CTC EcoZenith i250. If a heat pump is connected, the energy in the air or bedrock/ground is drawn up by the cooling system. The compressor then increases the temperature to a usable level. Afterwards it releases the energy for the heating system and hot water. The built-in immersion heaters help when additional heat is needed or when a heat pump is not connected. Fresh Water Connections Here you connect the property’s fresh water connections. The cold water is fed down and heated in the lower part of the coiling. Bivalent Mixing Valve The automated mixing valve ensures that an even heat is continuously supplied to the radiator system. Upper part In the upper part of the coil the hot water is then heated to the desired temperature. Insulation The heat pump’s tank is insulated with die-cast polyurethane foam for minimal heat loss. Finned Coil for Hot Water The EcoZenith i250 is equipped with a welldimensioned finned coil made of copper. Since hot water is not stored, there is no risk of legionella bacteria. Upper immersion heater Built-in upper immersion heater. When connected to a heat pump, the immersion heater acts as additional heat. Lower immersion heater Built-in lower immersion heater. Not used in normal operation when the heat pump is connected. Draining/expansion vessel connection Two connections in the lower part of the product where water from the boiler and radiator system can be drained and an expansion vessel connected. 14 Heat pump pipes The CTC EcoZenith i250 L is equipped with connection pipes for top connection CTC EcoZenith i250 Lower part In the lower part of the coil the hot water is pre-heated by the water heated by the heat pump. The major section of the coil is located in this part. Expansion connection 15 mm. Diverting valve The heated water from the heat pump heats up the upper or lower part of the tank alternately. Heat medium pump The adjustable-speed charge pump transports the cold water from the boiler to the heat pump where the energy from the air or bedrock/ground is drawn up and taken back to the boiler. The boiler is supplied with a circulation pump for a heat pump of up to 12 kW! General Information 5.

See more detailed information about this in the chapter on Your property’s heating installation. The value set corresponds to the temperature of the radiators when the outdoor temperature is -15ºC. After this default setting, fine adjustment takes place in the “Room temperature” menu. Adjustment 0 (-20...20) The curve adjustment means that the temperature level can generally be raised or lowered at all outdoor temperatures. After this default setting, fine adjustment takes place in the “Room temperature” menu. Room temp. reduced -2 (0...-40) “Room temp. reduced” is displayed if a room sensor is installed. You define here how many degrees the room temperature will be reduced by during the various scheduled reduction periods, e.g. Night reduction, Holiday, etc. Example: Room temp red -2 means that the room temperature is reduced by 2 °C from its normal temperature. Example: As a general rule, a Prim reduced value of 3-4 °C is equivalent to a 1 °C reduction in room temperature in a normal system. Prim reduced -3 (0...-40) If there is no room sensor installed, “Prim reduced” is displayed instead.

A low setting is recommended. The immersion heater is also responsible for providing the house with additional heating. If the house requires a higher temperature than that selected, the control system compensates by automatically raising the temperature of the immersion heaters. This temperature also reflects the settings chosen under DHW. Upper boiler add heat °C 57 (30...70) The temperature of the boiler when EcoZenith i250 calls for assistance to reach the high temperature; the immersion heater then works up to this value after the set time delay on the mixing valve. Upper boiler extra DHW 60 (30...70) This means the boiler is to provide extra DHW. This setting determines whether the electric heater should help to produce extra hot water. Set the temperature of the electric unit to the desired value when the option for extra hot water is activated under the DHW menu.

Several minutes may pass before the display communicates clearly after restart. General Information 9. Operation and Maintenance When the installer has installed your new system, you should check along with the installer that it is in perfect operating condition. Let the installer show you where the switches, controls and fuses are so that you know how the system works and how it should be maintained. Bleed the radiators after around three days of operation and top up with water if required. increase decrease Boiler and radiator system safety valve Check around four times a year that the valve is working by manually turning the control. Check that water is coming out of the safety valve discharge. Mixing Valve The mixing valve is operated automatically from the control system, ensuring that the radiators reach the correct temperature, no matter what season it is. However, where a fault occurs, you can operate the valve by pulling out the knob on the motor and turning it clockwise to reduce the temperature or anticlockwise to increase it. Draining the tank The CTC EcoZenith should be disconnected from the power source when it is being drained. The drain valve is positioned at the bottom left of the unit when viewed from the front, behind the front of EcoZenith. When draining the whole system, the mixing valve should be fully open, i.e. turned anticlockwise as far as it will go. Air must be supplied to the closed system. ! Do not forget to reset the mixing valve to the automatic position by pushing in the knob again. Operation stop The CTC EcoZenith i250 is shut down using the operating switch. If there is a risk of the water freezing, all the water should be drained from the heat pump and the radiator system (see drainage above). The DHW circuit, which contains around five litres, must also be emptied. Disconnect the cold water connection to CTC EcoZenith i250. Feed a hose into the cold water connection to CTC EcoZenith i250. The hose must go down to the bottom of the coil for all the water to be drained. Draining is carried out by siphoning out the water. CTC EcoZenith i250 49 General Information 10. Troubleshooting/appropriate measures The CTC EcoZenith i250 is designed to provide reliable operation and high levels of comfort, and to have a long service life. Various tips are given below which may be helpful and guide you in the event of an operational malfunction. If a fault occurs, you should always contact the installer who installed your unit. If the installer believes the malfunction is due to a materials or design fault, then they will contact Enertech AB to check and rectify the issue. Always provide the product’s serial number. DHW Many people want to gain maximum benefit from the CTC EcoZenith i250’s low operating costs. ! The control system is equipped with three comfort levels for hot water. We recommend starting at the lowest level and if there is not enough hot water, increase it to the next level. We also recommend that you operate a regular hot water pattern. Check that the hot water temperature is not being affected by a poor mixing valve, whether in the CTC EcoZenith i250 or possibly the shower mixer. The Heating System A room sensor, which should be fitted when possible, ensures that the temperature in the room is always suitable and stable. For optimal running, radiator thermostats should always be fully open in the area where the room sensor is located. ! Avoid running hot water at the highest flow capacity. If you run a bath at a rather slower rate instead, you will get a higher temperature. Avoid placing the room sensor close to the stairway due to the uneven air circulation. A correctly operating heating circuit is of significant importance to the heat pump’s operation and affects energy savings. When adjusting the system, always do so with all radiator thermostats fully open. The thermostats can be individually adjusted after a few days in rooms where lower temperatures are desired. 50 CTC EcoZenith i250 ! If you do not have radiator thermostats on the upper floor, you may need to install them. General Information If you do not achieve the set room temperature, check: • that the radiator system is correctly adjusted and is functioning normally. that radiator thermostats are open and the radiators are equally warm all over. Touch the entire radiator surface. Bleed the radiators. The CTC EcoZenith i250's economical operation demands a radiator system that functions effectively. • that EcoZenith is operating and no error messages are displayed. • that there is sufficient electrical power available. Increase if necessary. Also check that the electric power output is not limited due to excessively high electricity loads in the property (load monitor). • that the product is not set to the “Max. allowed primary flow temperature” mode with a too low set value. • that “Primary flow temperature at –15°C outdoor temperature” is set sufficiently high. Increase if necessary. More can be read about this in the chapter on The house heating curve. However, always check the other points first. • that the temperature reduction is set correctly. See Settings/Radiator system. • that the mixing valve is not in the manual position. If the heat is not even, check: • that the placement of the room sensors is appropriate for the house. • that the radiator thermostats don’t interfere with the room sensor. • that no other heat sources/cold sources interfere with the room sensor. • that the mixing valve is not in the manual position. CTC EcoZenith i250 51 General Information Current Monitor The CTC EcoZenith i250 has an integrated current monitor. If the system is fitted with a current sensor, the property’s main fuses are continuously monitored to ensure they are not overloaded. If this should happen, electric stages are disconnected from the CTC EcoZenith. The electrical power of the CTC EcoZenith i250 may be restricted where high heating requirement levels are combined with, for example, single-phase motor heaters, cookers, washing machines or tumble dryers. This may result in inadequate heating or hot water temperatures. If the CTC EcoZenith is restricted, “High current, elpower redu (X A)” appears in text form in the display. Consult an electrician to determine whether the fuse size is correct or the three phases in the house are evenly loaded. Vent valve Air problems If you hear a rasping sound from the tank, check that it has been properly bled. Turn the boiler vent valve so that any air can be evacuated. Top up with water where required, so that the correct pressure is achieved. If this noise recurs, call a technician to check the cause. Unusual noise when shutting off DHW In some cases, unusual noises may be produced by the house's pipe system and the CTC EcoZenith i250 due to the jolts which occur when the flow is quickly interrupted. There is no fault with the product, but the noise may occur when older model outlets are used. More recent outlets are often fitted with a soft-closing mechanism. If an unusual sound comes from hard-closing dishwasher and washing machines, this can be remedied using a shock arrestor. A shock arrestor can also be an alternative to soft-closing water taps. Motor protection (when heat pump is connected) The CTC EcoZenith i250 constantly monitors the compressor’s operating current and an alarm is triggered if the compressor is using an unusually high current. When a fault occurs the message "Motor protect high current" is displayed. The cause of the fault may be as follows: • Phase failure or mains interruption. Check the fuses, which are the most common cause. • Compressor overload. Call out a service engineer. • Faulty compressor. Call out a service engineer. • Inadequate circulation between the heat pump and boiler. Check the heat medium pump (left pump, viewed from front). Call out a service engineer. • Abnormally high temperature in the brine circuit. Call out a service engineer. 52 CTC EcoZenith i250 ! Don’t forget that the radiators may also need bleeding. General Information 10.1 Information messages Information messages are displayed when appropriate and are intended to inform users about various operational situations. Start delay Start delay The compressor is not allowed to start too quickly when it has stopped. The delay is usually approx. 10 minutes. Heating off, radiator sys Shows that the product is operating in summer-time mode when only hot water is required, not heating. Ripple control Shows that ripple control is active. Ripple control is a device which an electricity provider can fit with the aim of disconnecting high current draw equipment requiring power for a short period of time. Not currently in use in the UK. The compressor and electrical power are blocked when ripple control is active. High current The property’s main fuses are overloaded due to the fact, for instance, that several appliances requiring power are being used simultaneously. The product reduces the electrical power over time. Tariff, HP off. Not used. Tariff, EL, off. Not used. Compressor blocked The compressor is set to be shut down, e.g. before drilling or digging has been carried out for the collector loops. The product comes with the compressor shut off. This option is selected under the Installer/Settings/Heat pump menu. CTC EcoZenith i250 53 General Information 10.2 Alarm texts Alarm: Wrong phase order compressor Reset alarm If a fault occurs with a sensor, for instance, an alarm is triggered. A message appears on the display with information about the fault. You reset the alarm by pressing the Reset alarm button on the display. If several alarms are triggered, they are displayed one after the other. An outstanding fault cannot be reset without being rectified first. Some alarms are reset automatically if the fault disappears. The description below also includes an alarm for connected heat pump. Alarm text Description Wrong phase order compressor The product’s compressor motor must rotate in the right direction. The product checks that the phases are connected correctly; otherwise, an alarm is triggered. In this case, two of the phases to the product need to be changed. The power supply to the system must be shut off when rectifying this fault. This fault generally only occurs during installation. Alarm sensor An alarm is displayed if a fault occurs with a sensor that is not connected or has short-circuited and if the value is outside the sensor's range. If this sensor is important to the system’s operation, the compressor stops. In this case, the alarm is reset manually after the fault has been rectified. For the following sensors the alarm is reset automatically after correction: Sensor upper tank (B5), Sensor lower tank (B6), Sensor prim flow 1 (B1), Sensor prim flow 2 (B2), Sensor out (B15), Room sensor 1 (B11), Room sensor 2 (B12), Sensor brine out, Sensor brine in, Sensor HPin, Sensor HPout, Sensor discharge, Sensor suction gas, Sensor high pressure, Sensor low pressure. 54 Motor protect compressor High/low current has been detected to the compressor.

Manometer system pressure (95) Fit the manometer on the expansion pipe or radiator return pipe. Electric shut-off valve (47) If the sub-mixing valve (radiator system 2) is to operate in the summertime while radiator system 1 is switched off, the system can be supplemented by an electric shut-off valve that closes the flow through the switching off of radiator pump (G1). CTC EcoZenith i250 61 Installation Expansion vessel connection The CTC EcoZenith i250 is best connected to a closed expansion vessel. The CTC EcoZenith i250 is designed to be fitted to an 18 l closed expansion vessel. The expansion vessel is either fitted in the area under the tank or on top of the product (see pictures). The expansion vessel with installation kit is available as an accessory. Expansion vessel for installation above the tank. ! Expansion vessel for installation under the tank. NB: If the heat pump is not connected, the connections not being used must be capped off! If you connect the product to an open system, the distance between the expansion vessel and the highest placed radiator must not be less than 2.5 metres in order to avoid introducing oxygen into the system. Note that no hot water circulation may be connected as it affects the function of the EcoZenith and the system. If the EcoZenith i250 is connected to another heat source, e.g. an existing boiler, the installations must have separate expansion vessels. Water taps In some cases, unusual noises may be produced by the house’s pipe system and the EcoZenith i250 due to the jolts which occur when the flow is quickly interrupted. There is no fault with the product, but the noise may occur when older model outlets are used. More recent outlets are often fitted with a soft-closing mechanism. Alternatively, a shock arrestor can be fitted. Keeping the jolting to a minimum also helps avoid unnecessary wear and tear affecting the DHW system. 62 CTC EcoZenith i250 Installation 12.3 Connection to heat pump The heat pump is connected to the top (CTC EcoZenith i250L, see figure below) or bottom (CTC EcoZenith i250H). The charge pump for the heat pumps is factory-installed in the CTC EcoZenith i250L. The CTC EcoZenith i250 L has pipes at the rear right edge for connection of the heat pump. The CTC Eco Air’s lower connection (5) is connected to the right connection (2) when viewed from the front, so that water is pumped out to the heat pump. The CTC EcoAir's upper connection (4) is thus connected to the left connection (1). The CTC EcoZenith i250 H heat pump is connected directly to the supplied charge pump (3) located under the tank. The heat pump’s lower connection (5) must be connected to the charge pump (3) so that water is pumped out to the heat pump. The heat pump’s upper connection is connected to the right diverting valve (viewed from the front). Draining: A drain valve must be fitted to the EcoZenith’s left connection (where the charge pump is mounted). It functions as drainage for both the boiler and the radiator system.

Energyflex Energyflex is a collective term that describes CTC's unique opportunity for maximum flexibility and combining difference heat sources in a simple way. The most common combination is a heat pump and electric boiler. It is worth noting here that when installed the CTC EcoZenith i250 can serve as an electric boiler alone, but it can subsequently be augmented with: CTC EcoPart Heat Pump (ground source)) CTC EcoAir Heat Pump (air to water) Solar Energy The CTC EcoHeat/EcoZenith now has integrated functionality for simple augmentation with Solar Energy Pool Wood-Fired Heating Regarding wood-fired heating: The integrated "Differential thermostat function" control initiates the charge from, e.g., the existing wood-fired system or fireplace when the temperature is higher than it is in the CTC EcoHeat/EcoZenith i250 Bear in mind that it can also be a good idea to install an automatic charger that can protect the wood-fired system from condensation, etc If the wood-fired system needs more water than the 223 l contained in the product, the system needs to be supplemented with an accumulator tank. Example of wood-fired system with group of chargers ! Energyflex can also be used to draw energy, e.g. to heat a swimming pool Connecting external systems can seriously affect the EcoZenith’s operation and performance and can therefore produce undesirable effects if the system is not installed correctly. If you are unsure how to make the connection, contact CTC for suggestions on how to install the system. Schematic diagram only The installer adds expansion vessels, safety valves, etc., and sizes the system. 66 CTC EcoZenith i250 Installation Introduction Energyflex - EcoSol The CTC EcoHeat and CTC EcoZenith i250 H/L have a water volume of 223 l with layered disc and solar output.

H Solar output (3/4) H. Symbol of tank volume in CTC EcoHeat 400 and CTC EcoZenith i250. The tank in the CTC EcoHeat 400 and CTC EcoZenith i250 will be called the H-tank (main tank). Energy can be collected through the solar outputs (solar panels, wood-fired boiler) or generated (swimming pool). Available as accessories are pre-bent pipes with couplings and insulation to facilitate installation. Also available as accessories are CTC Solar Control/Expansion Card Accessory pipe kit Energyflex kit 400 fitted to H-tank CTC EcoZenith i250 67 Installation System options, Energyflex The flexibility in the CTC EcoHeat and CTC EcoZenith i250 is optimised because the products contain functionality for five basic systems. These are: Solar "system 1" Solar "system 2" Solar "system 3" Diff thermostat function Pool Solar also offers the facility to recharge the drill hole or collect energy for an extra tank, with or without a solar coil. *The differential thermostat function can be connected to an existing PCB in the CTC EcoHeat 400/CTC EcoZenith i250, while Solar systems 1, 2, 3 and Pool require the product to be supplemented with the CTC Solar Control/ Expansion Card accessory. Explanations of system options Solar system 1 Charge from solar panels only to the H-tank (H) in the CTC EcoHeat 400 or CTC EcoZenith i250 Solar system 2 Charge from solar panels only to the EcoTank buffer tank + CTC EcoHeat 400/CTC EcoZenith i250. Solar system 3 Charge from solar panels either to X-Volume or CTC EcoHeat 400/ EcoZenith i250. Using a diverting valve, the charge is prioritised either to the H-tank in the EcoHeat/EcoZenith i250 or to the external X-volume G99 G98 B5 Diff thermostat function The differential thermostat function is used if you want to charge your EcoHeat/EcoZenith from an existing wood-fired boiler, a water-jacketed stove or another cheap heat source. The function compares the temperature in the EcoHeat/EcoZenith and the external heat source. Charging starts when it is warmer in the external heat source. NB: For certain heat sources, e.g. solid fuel boilers, automatic chargers are recommended, among other things to counteract condensation in the fire box.

Electrical installation Installation and connection in the CTC EcoZenith i250 must be undertaken by an authorised electrician. All wiring must be installed according to applicable regulations. The boiler is internally connected by the factory and set for a 5.5 + 6.0 kW power output. Depending on the country in which CTC EcoZenith i250 is to be installed, it is available with a 400 V or 230 V electrical connection. Electrical connections are made behind the product's front panel. Undo the screws on the top (2 screws), bend out and put the front to one side (disconnect any network cables on the front printed circuit card for easier access). The terminal blocks are located behind the electrical connection box cover. Connection cables are inserted in the cable ducts on the unit’s top cover, which exit at the same height as the bottom of the electrical connections box. Sensor cables are inserted separately as far as possible through the cable ducts to the right of the product’s top cover. Safety switch The installation should be preceded by an omnipolar safety switch according to overvoltage category III, which ensures disconnection from all electric power sources.

The word TOP should be visible on the terminal and the cable clip (see figure 4) Push the cable clip onto the connector. Then tighten the screw to obtain the desired tension. see figure 5) Connector for supplying power to heat pumps! Figure 1 72 CTC EcoZenith i250 Figure 2 Figure 3 Figure 4 Figure 5 Installation 14.5 Extra low voltage protection The following outputs and inputs have extra low voltage protection: current sensor, outdoor sensor, room sensor, primary flow sensor, return sensor, NR/SO, temperature sensor, level switch and PWM signals. Connection of outdoor sensor (B15) The sensor should be set up on the house’s northwest or north side, so that it is not exposed to morning and evening sun. If there is a risk of the sensor being affected by the sun’s rays, it must be protected by a screen. Place the sensor at around 2/3 of the height of the facade near a corner, but not under a roof projection or other form of wind protection. Do not place it either above ventilation ducts, doors or windows where the sensor may be affected by factors other than the actual outdoor temperature. Connection of room sensor (B11) (B12) The room sensor is fitted at a central point in the house, in the most open position possible, ideally in a hall between several rooms. This is the best position for the sensor to record an average temperature for the house. Feed a three-conductor cable (minimum 0.5 mm2) between the heat pump and room sensor. Then attach the room sensor securely in a position at roughly two thirds of the way up the wall. Connect the cable to the room sensor and EcoZenith. ! Do not attach the sensor cable permanently until you have tested where the best location is. Connection of primary flow sensor (B1, B2) /return sensor (B7) Fit the primary flow sensor to the primary flow pipe, ideally after the circulation pump. Fit the return sensor to the return pipe. The sensing part is towards the end of the sensor (see sketch). Contact paste Sensory element Primary flow pipe Tie strap Sensors Sensor cable Insulation • Attach the sensor using the tie strap provided. • Ensure that the sensor makes good contact with the pipe. Apply contact paste to the front part of the sensor between the sensor and the pipe if good contact is otherwise difficult to obtain. • Important! Insulate the sensor using pipe insulation. • Connect the cables to the EcoZenith’s terminal board. CTC EcoZenith i250 73 Installation 14.5.1 Remote-controlled temperature reduction The night temperature reduction function can be activated via a closed function on the electricity remote control input, pins G33 and G34 on the terminal board. The function can be controlled remotely using “Minicall”, for instance. While the input is short circuited, the temperature reduction is activated, regardless of other settings. When the short circuit ceases, the product returns to ordinary settings. The size of the reduction is set in the menu: Installer/Settings/Radiator system/Prim reduced. NOTE: the input function can be selected according to the following: • NR = Night reduction of temperature (time-controlled lowering of temperature) • SO = Shut off (compressor and power output blocked by the electricity supplier) • DHW = Extra hot water button (accessory) 14.5.2Current sensor connection The three current sensors, one for each phase, are fitted on the fuse panel in the following manner. Each phase from the electricity distribution board supplying the EcoHeat is channelled through a current sensor before termination at the relevant terminal. This allows the phase current to be sensed all the time and compared with the value set for the heat pump's load switch. If the current is higher, the control unit drops to a lower heat output on the immersion heater. If this is insufficient, the heat pump is also limited. When the power drops back to the set value, the heat pump and immersion heater are reconnected. This means that the current sensors, along with the electronics, prevent more power being supplied than the main fuses can tolerate. The current sensors’ holes for cables are 11 mm in diameter. Use at least 0.5 mm2 cable.

First start When the CTC EcoZenith i250 is delivered, the heat pump is blocked to avoid it being started unintentionally. EcoZenith I250 can be installed and started before the bedrock/ground source or air/water heat pump is put into operation. The EcoZenith i250 can also be started without a room sensor being fitted as the curve which has been set then regulates the heating. Deselect the room sensor in the Settings menu. The sensor can however always be fitted for the alarm LED function. Before first start 1. Check that the EcoZenith I250 and system are full of water and have been bled. (The EcoZenith i250 is bled through the safety valve on the top cover Före of the första start 1. product.) 2. 3. 2. Ensure that, where applicable, the brine system is filled with water and anti4. 5. 6. Kontrollera att reservvärmetermostaten är i frostskyddsläge.

Frostskyddsinställning, ca + 7 °C. 3. Check that all connections are tight. 4. Check that sensors and the radiator pump are connected to the power screwdriver slot source. 5. The backup heating thermostat has OFF as its factory setting. The recommended position is = Antifreeze setting, around +7°C. The backup heating thermostat is reset on the electrical switchboard behind the front panel. It is in the OFF position when it is turned anticlockwise as far as it will go (the screwdriver slot should be vertical). Symbol for backup heating NB: At the end of the installation, check the current transformers’ thermostat: connection. In this situation it is important that you have switched off any major consumers of electricity in the house. Also make sure that the backup thermostat is turned off. CTC EcoZenith i250 91 Installation First start Switch on the power using the safety switch. The display comes on. CTC EcoZenith i250 now asks the following: 1. Select language and press OK 2. Confirm that the system is filled with water and press OK. Press next. 3. Size of main fuse Choose between 10 and 35 A. 4. Enter the supply voltage 3x400 (1x230/3x230 apply only to export variants) 5. Specify the maximum electric heater power. Choose between 0.0 and 9.0 kW in different steps. This applies to electric heaters in the upper tank. 6. Select the option permitting the compressor (if the collector system is ready or the air/water pump is already installed). When the compressor is started for the first time, it is automatically checked that it is running in the correct direction. An error message is displayed in the panel display if it is rotating in the wrong direction. Switch any two phases to change the direction of rotation. 7. Brine pump On, Auto (Auto/10d/On) (For CTC EcoHeat/EcoPart only) Auto means that the brine pump is automatically operating at the same time as the heat pump (factory setting). 10d means that the brine pump is running continuously during the first 10 days in order to assist with bleeding. “On” means that the brine pump is running constantly. 8. Specify max. primary flow 1 °C for radiator system 1. 9. Specify inclination 1 for radiator system 1. 10. Specify the adjustment for radiator system 2. 11. Current sensors identified. The CTC EcoZenith i250 then starts and the start menu appears. 12. Enter the set values in the parameter list so that the customer knows what has been set in addition to factory settings during installation. 92 CTC EcoZenith i250 !
