5 For Home Owners System description System description Principle of operation is an indoor module designed for houses/smaller properties with waterborne heating. The indoor module consists of a pressure vessel, two immersion heater, charge pump as well s intelligent control and is suitable for docking with NIBE's air/water heat pumps. Hot water heating occurs via a cam pipe coil. The low internal volume and high circulation rate of the water in the coil prevents bacterial growth. In the event of a domestic water flow greater than 12 l/min, supplementing with a core water heater is recommended. The immersion heaters have a max output of 18 kw withoption of setting lower outputs. The supplied output is 9 kw. The indoor module and heat pump work optimally towards a heat distribution system of up to 55/45 C at dimensioned outdoor temperature. At higher flow line temperatures (maximum 65 C) heat pump operation can be limited. If the heat pump operation is limited the installation only works with the addition. The heat pump starts when temperatures permit operation again. For further information about system limitation, see the heat pump manual. The total boiler water volume is 500 litres.

In Offset, heating curve With the knob "Offset heating curve", you can change the heating curve offset and hence the room temperature; see section "Default setting" on page 6 and "Setting of flow temperature" on page 26. * If the heat pump is made by a manufacturer other than NIBE, see section "Electrical connection" on page 17. 5

8 For Home Owners Room temperature Room temperature Heating control system The indoor temperature depends on several factors. During the hot season, solar radiation and heat given off by people and equipment are sufficient to keep the house warm. When it gets colder outside, the heating system must be started. The colder its gets, the hotter the radiators must be. This adjustment is made automatically, however the basic settings must first be made on the indoor module, see the section Default setting on page 6. Default setting For optimum operational economy, make settings first on the indoor module with any room thermostats fully open. When the correct "Heating curve selection" and "Offset, heat curve" have been selected, the thermostats can be controlled to compensate for solar radiation etc. For basic setting, use the knob "Option, heating curve" and the knob "Offset heating curve". If the required room temperature is not obtained, readjustment may be necessary. Readjustment the default settings Cold weather conditions If the room temperature is too low, increase the curve offset setting by one step. If the room temperature is too high, reduce the heating curve setting by one step. Warm weather conditions If the room temperature is too low, increase the curve offset setting by one step. If the room temperature is too high, reduce the curve offset" setting by one step. heating Option, heating "Heating NOTE Wait one day between settings so that the temperatures have time to stabilise. Changing the room temperature manually If you want to temporarily or permanently lower or raise the indoor temperature relative to the previously set temperature, turn the "Heating curve offset" knob anticlockwise or clockwise. One line approximately represents a 1 degree change in room temperature. NOTE: An increase in the room temperature may be limited by the radiator or underfloor heating thermostats, if so these must be turned up. 6

9 For Home Owners Hot water temp. Hot water temp. Upon delivery, the indoor module is set to normal mode on the knob and 60 C on the knob. This usually gives a good combination of optimal savings and comfort. To increase the hot water capacity (the comfort): In cold weather Turn the knobs and one step clockwise. In hot weather Turn the knob, one step clockwise. If the hot water capacity is sufficient, both knobs and can be turned one step counterclockwise. This results in less comfort but greater savings.

The heating system s safety valve must be completely tight, but the water heater s safety valve may occasionally release some water after hot water has been used. This is because the cold water, which enters the water heater to replace the hot water, expands when heated causing the pressure to rise and the safety valve to open. The safety valves must be checked regularly. Check as follows: Open the valve. Check that water flows through the valve. Close the valve again. Check the pressure. If the pressure is too low, top up the boiler water. NOTE In the event of a domestic water flow greater than 12 l/min, it is recommended to supplement with a core water heater. 7

10 For the Installer General information for the installer General information for the installer Transport and storage The inside module should be transported and stored vertically in a dry place. If the inside module has to be transported horizontally, this should be done with care. Assembly The indoor module is ideally located in a utility room or boiler room. The unit can be aligned using the adjustable feet. The inside module's factory-fitted lifting eye can be removed after installation and the insulation plug enclosed is pressed into place in order to reduce heat losses. If pipes are to be routed on an internal wall that backs on to a bedroom or living room, this must take place without clamping. Inspection of the installation Current regulations require the system to be inspected before it is commissioned. The inspection must be carried out by a suitably qualified person and should be documented. The above applies to closed heating systems. Therefore, the boiler must not be replaced without reinspection. Connection Pipe installation must take place in accordance with applicable heating and hot water standards. Internal support bushes should be fitted when an annealed copper or steel pipe is used. Overflow pipes from safety valves must be passed to floor drains so that hot water cannot splash when the valves have to checked or the indoor module vented. The overflow pipe must be routed enclosed along its entire length to prevent water pockets and be frost proof. The outlet of the pipe must be clearly visible. The hot water circuit must be provided with a mixing valve as the boiler temperature can exceed 60 C and there is a risk of scalding. can be connected to both an open and a closed expansion tank. If the heating system is provided with an open expansion tank, the distance between the highest radiator and the expansion tank must be no less than 2.5 m. Min 2,5 m 8

11 ARMATUR For the Installer General information for the installer Extra electric hot water heater The facility should be supplemented with an electric water heater, if a hot tub or other significant consumer of hot water is installed. If the heater is equipped with a valve connector Ø 15 mm this should be replaced with a corresponding one (separable) Ø22mm. Appropriate heater is COMPACT for floor mounting and EMINENT for wall mounting. 1. Separate the valve connector. 2. Install the valve connector part on incoming cold water to the heater. 3. Install the mixing valve part on outgoing hot water from the heater. 4. Plug the part on the valve connector part.

12 For the Installer Electrical connections Electrical connections Folding down the front panel The front panel folds down by undoing the two screws at the top of the panel. The panel can then be folded down into a horizontal position (against stop lugs on either side of the front panel). Rear of front panel 33 LEK 34 Strain relief device When connecting an electrical output greater than 9 kw, the strain relief device for the supply cable needs to be replaced with an enclosed strain relief device. For cables up to 2.5 mm 2, the small one can ideally the factory fitted strain relief device be used. The one included is fitted for thicker cables. 10

13 LEK For the Installer Electrical connections X9 X12 X10 X11 Connection Disconnect the indoor module before insulation testing the house wiring. must be installed via an isolator switch with a minimum breaking gap of 3 mm. When the building is equipped with an earth-fault breaker, should be equipped with a separate one. Remove the upper cover. The connection cable must be connected to the terminal block (X9) according to the terminal block's markings and installed in one of the strain reliefs for the cable. 0 N L L1 L2 L3 X9 Resetting the temperature limiter The temperature limiters (6) 1 and 2 interrupt the power supply to the immersion heaters and the boiler temperature is between 90 C and 100 C, these can be reset by pressing the button on the relevant temperature sensor. The temperature limiters (6) 1 and 2 can be accessed behind the lower cover, where they are positioned on top of the panel. These can be reset by pressing the buttons on the respective temperature limiters. NOTE Reset the temperature limiters, they may have tripped during transport. NOTE Electrical installation and service must be carried out under the supervision of a qualified electrician. Electrical installation and wiring must be carried out in accordance with the stipulations in force. 6 6 NOTE The switch (8) must not be moved from "0" until the boiler has been filled with water. Otherwise the temperature limiter, thermostat and immersion heater may be damaged. Internal fuse protection Automatic elements, charge pump (17) and its cabling are fuse-protected internally with a miniature circuit breaker (7), plus a fine-wire fuse (33) on the relay card (34). 11

14 For the Installer Electrical connections Power rating as set at the factory The two immersion heaters have a total max. output of 18 kw. The power rating as set at the factory is 9 kw. Max phase current Immersion heater, output (kw) Max load phase (A) Different max outputs are set using the knob "Max electrical output" (61) on the relay card (34) LEK 12

15 For the Installer Electrical connections Connecting the outside sensor The outside sensor (15) must be installed in a shaded location on a wall facing north or north-west, where it will not be affected by the morning sun, for example. This sensor is connected by twin cables to terminal (X12), positions "7" and "8". The minimum cable cross section should be 0.4mm 2 up to lengths of 50 metres, for example, EKKX or LiYY. External Externt UG X12 Input for external power monitor The indoor module is provided with a control input for an external output monitor. The output (potential free) of the external output monitor is connected to terminal (X12), positions "5" and "6". If positions "5" and "6" are closed, any connected electrical steps are gradually disconnected at 10 second intervals until the current does not exceed the permissible value. Reconnection of the additional electricity then occurs automatically. X12 Quick start boiler mode During normal operation, it takes one hour from boiler operation activation until the first electrical step cuts in, and then one hour between each electrical step. To shorten the time until the first electrical step cuts in, it is possible to quick start by: 1. Bridge both tariff A (electrical tariff) and tariff B (compressor tariff), terminal block X12 terminal 1 and 2 as well as 3 and Remove tariff A terminals 1 and 2. This means that the first electrical step cuts in after only 5 seconds. 3. When the first electrical step is activated, tariff B, terminal block 12, terminals 3 and 4 are also removed to allow the compressor in the heat pump to produce heat. Blocking room heating during tariff control The supplied bridge is used to save the stored heat energy in for hot water production, when both tariff A and B are activated. Connect the bridge on the microprocessor board (41), terminal block X3 between terminals 31 and 32. With the bridge installed, the shunt valve closes completely as tariffs A and B are activated at the same time. This means that no heat is retrieved from. During the time that tariff A and B are activated, no new hot water is produced, only access to existing hot water is available. LEK Centralised load control/tariff If tariff control is use, it can be connected to terminal (X12). If positions 1 and 2 are closed, all electric addition will be blocked. If positions 3 and 4 are closed, heat pump operation will be blocked. However, this assumes that the docked heat pump is F20XX. X12 13

16 For the Installer Electrical connections Input for external charge pump feed If does not have to be docked with F20XX but with some other external heat source, the charge pump can still be used. This is achieved by manually supplying the charge pump externally via terminal (X10) positions 1 and 2 in accordance with the required operating conditions. In addition, the connector (13) must be moved from an internal socket to an external one as shown in the diagram below. External additional relay When is to be docked to an external heat source designed to replace the additional heater, terminal (X11) may be used to control switching this on and off. When the additional heater is to be activated, contact is achieved between terminal (X11) position "1" and position "3". This contact is potential free and activated according to the same conditions as the additional heater. 13 Temperature sensor data Temperature ( C) Resistance (k ) , , , , , , , ,17 0 9,81 5 7, , , , , , , , , , , ,525 Voltage (V) 3,16 3,10 3,04 2,95 2,85 2,72 2,57 2,41 2,23 2,04 1,85 1,65 1,47 1,29 1,12 0,97 0,84 0,72 0,62 0,46 0,34 X11 NOTE Supply for external ciculation pump in the heating system is not available in 14

Cut the plastic cover according to the punched pattern. Electric boiler mode If is to be used without a heat pump, e.g. if a fault has occurred in the heat pump or if the heat pump has not yet been installed, a jumper must be placed between positions 3 and 4 on terminal (X12). This stops the boiler signalling a communications alarm when communication with F20XX is not found. then functions as a purely electric boiler with automatic heating controls, although without freeze protection. X12 Electrical connection When connecting an air/water heat pump other than F20XX, it will not be possible to utilise parts of the intelligence in the controls of. It is best to place a suitable thermostat which operates the heat pump's on and off control in the s submersible tube to the heat pump sensor. To use the integral charge pump, an external supply is required at terminal (X10), positions 1 and 2 according to the operating conditions required (e.g. frost protection circulation). In addition, the connector (13) must be moved from an internal socket to an external one. The electric boiler temperature is set using the knob to a suitable temperature (lowest reference value supply line at DOT). Place a jumper between positions 3 and 4 on terminal (X12). This ensures that the boiler does not signal a communications alarm when communication with F20XX is not found. There are three options for blocking immersion heater operation as the heat pump alone is able to cover the heating requirements in the building. It is most appropriate to use a relay which bridges positions "1" and "2", i.e. the tariff electricity supplement is activated when the heat pump has full coverage, output-wise. The other alternative is to manually block the additional heater, as the heat pump alone is able to meet the heat requirements by setting the change-over switch on the control panel to "OFF". When the heat requirement is then not met by the heat pump alone, the change-over switch is set back to "ON". The third alternative is to set potentiometer (61) to 0 kw. NOTE X12 X12 There is a risk of freezing if immersion heater operation is blocked. 17

24 For the Installer Commissioning and adjusting Commissioning and adjusting Preparations Check that the switch (8) is set to "ON" and that the temperature limiters (6) have not tripped (press the button hard to reset). Addition It is best to top up the indoor module by means of a fixed filler pipe to the radiator return. Venting the heating system Bleed the indoor module via the bleeder nipple (81) and the rest of the heating system through the relevant venting valves. Keep topping up and venting until all air has been removed and the pressure is correct. Start-up and inspection 1. Check that the water is full and vented. 2. Turn on the main circuit breaker. 3. Check that all incoming phases are powered. 4. Check that the miniature circuit-breaker (7) is on. 5. Check that the temperature limiters (6) have not tripped during transit. 6. Turn on the switch (8). 7. Adjust the curve coefficient and heating curve offset according to the requirements of the property using the knobs and. 8. If F20XX is not to be connected, bridge positions 3 and 4 on terminal (X12). Continue with the following points if is to be docked to NIBE's air/water heat pump. 1. Connect a shielded communications cable between F20XX and as per "Communication between and F20XX" on page Follow the start-up and inspection instruction for the respective heat pumps. 3. Check that the value is 1 in channel A1 in F2020/F2025 (in F2005/2010 channel 13 must be set to 2). 4. Set the heating system's balance temperature (according to dimensioning) in channel A5 in F2020/F2025 or channel 17 in F2005/F Adjust the charge flow between the heat pump and EVP 500 using the mode switch on the charge pump. Guideline value balance temperature The table applies at DOT and with an approximate hot water demand of 5000 kwh/year and a heat distribution system with a maximum supply/return temperature of 55/45 C. Where the table only contains guideline values, it is important that the heating system's balance temperature is dimensioned, preferably with the dimensioning tool VPDIM.

25 For the Installer Commissioning and adjusting Setting of temperature levels The indoor module and, indirectly also the cam pipe coil, is, on delivery, set to normal stop temperature NORM for the heat pump and 60 C electric boiler temperature. All additional power is blocked until the heat pump can no longer manage the entire heating demand itself (below the balance temperature). This means that the electric boiler temperature is significant only below the heat pump's balance temperature. In the case of outdoor temperatures above the balance temperature, the heat pump's stop temperature is thus controlled and so all the comfort of hot water is controlled via the knob. The heat pump's stop temperature is variable and depends on the knob setting and outdoor temperature. At a higher outdoor temperature, the heat pump does not need to work as hard to get up to boiler temperature as it does when the outdoor temperature is colder, so increasing savings (see the diagram below). The temperature in the cam pipe coil increases as the boiler temperature increases. The output hot water temperature can be limited by means of a mixer valve (not included as standard). The maximum supply temperature can also be limited upwards in temperature (35 C - 65 C) to protect an underfloor heating system for example. This is done via a potentiometer (62) on circuit board (34), which is located behind the front panel. The indoor module's maximum power output is also set on the same circuit board (34) via potentiometer (61) and can be adjusted between 0-18 kw in stages of 3 kw. The power stages are connected, if necessary, at hourly intervals, on the condition that "Operating mode, immersion heater " is on position "on". The connection difference between start/stop temperature is set using potentiometer (60). At outdoor temperatures above 10 C, boiler control is automatically set to 1 C on the connection difference's setting to extend the heat pump's operating time when the given output is high.

26 For the Installer Commissioning and adjusting Adjustment, charge flow F20XX Adjusting the temperature difference ( T) between the heat pump's supply temperature and the heat pump's return temperature is important to maintain optimal operational economy. This is most easily done using the temperatures measured in channel T2 (supply temperature) and channel T3 (return temperature). This temperature difference ( T) is adjusted using the charge pump. Adjustment is performed with stable operation about 5 minutes after start, or about 5 minutes after defrosting in cold outdoor temperatures. NOTE The temperature difference must be within the grey marked area in the diagram below. Adjust as close to the nominal value as possible.

If bubbling sounds can be heard from the indoor module, the entire system requires further venting. When the system is stable (correct pressure and all air eliminated) the automatic heating control system can be set as required. See the sections "Heating control system" on page 6 and "Functions on the front panel" on page 4. Draining the heating system The power supply must be disconnected before the boiler/radiator water is drained. The boiler/radiator water can be drained via drain valve (44). Loosen the cover of the drain valve and mount the supplied hose connector to an appropriate hose. NOTE The hose must be fitted to the hose coupling supplied before being fitted to the drain valve (44). The valve opens automatically when the hose coupling is fitted to the valve. 25

This means the flow temperature is regulated in relation to the current outdoor temperature. The relationship between outdoor temperature and supply temperature is set with the Heating curve selection and Heating curve offset knobs. The diagram is based on the dimensioned outdoor temperature in the area and the dimensioned flow temperature of the heating system. When these two values meet, the heating control's curve coefficient can be read. The Heating curve offset knob is then set. A suitable value for underfloor heating is -1 and for a radiator system -2.

29 Miscellaneous Dealing with malfunctions Dealing with malfunctions In the event of malfunction or operating disturbances first check the points below. Remember that there is an hour interval between each power stage. Low hot water temperature or no hot water Too high domestic water flow. See section Hot water temp. on page 7. Large amounts of hot water were used. Circuit or main MCB tripped. Possible earth circuit-breaker tripped. Mixer valve set too low (if mounted). Switch (8) set to 0. Tripped Miniature circuit-breaker (7) or Fine-wire fuse(33). Refer to the section "Resetting the miniature circuit breakers" on page 29. Tripped temperature limiters (6). Contact service. Check if "operating mode, immersion heater" is in mode OFF Closed or throttled shut off valve to the water heater. External output monitor may have blocked the electrical power. Hot water capacity is set too low on and/or. "Balance temperature" set too low in F20XX. Alarm indicator, see "Alarm" on page 29. High hot water temperature Mixer valve set too high. Low room temperature Circuit or main MCB tripped. Possible earth circuit-breaker tripped. Tripped Miniature circuit-breaker (7) or Fine-wire fuse(33). Refer to the section "Resetting the miniature circuit breakers" on page 29. Tripped temperature limiters (6). Contact service. Incorrectly set values for "Option, heating curve" and/or "Offset heating curve" on page 6. Circulation pump stopped. Air in the indoor module or in the system. The pressure is to low in the expansion vessel. External output monitor may have blocked the additional heater. "Balance temperature" set too low in F20XX. Alarm indicator, see "Alarm" on page 29. Electric boiler operation due to blocked heat pump The heat pump may be blocked due to a high supply or return temperature, which can depend on incorrect heat pump and/or indoor module settings. When the heat pump is blocked, this is indicated by three flashes on the operating mode indicator on. 1. Set the heating system's balance temperature in F20XX. 2. The charge flow between supply and return to the heat pump (T2 - T3) must be according to the diagram on page A high set value on the heat curve results in a high supply temperature, which in turn, results in a high return temperature. The heat pump is then outside its working range. 4. The flow in the heating system is limited by the thermostats for the radiators or underfloor heating. Instead, regulate the room temperature using "Heating curve selection" and "Offset, heat curve" on (see page 6). 5. Check that "temperature sensor, heat pump" (89) is correctly installed in the submerged tube on. 6. Adjust T above the heating system using the heating medium pump or any external valves according to the projected flow for the house. 7. In the event of docking to another heat source, the charge temperature should be limited to C. 8. The heat pump's output can be limited by the heating system. High room temperature Incorrectly set values for "Option, heating curve" and/or "Offset heating curve" on page 6. 27

30 Miscellaneous Dealing with malfunctions Switch position In "Reserve mode", the indoor module's electronic control is disconnected. The immersion heater is controlled by a separate thermostat (3), and the available output in reserve mode is 9 kw. The charge pump is functional, but the automatic heating control system is not, so manual shunt operation is required. This is done by using a screwdriver to set the change-over switch on the shunt motor (19) in mode. The shunt motor can then be turned to the desired position. LEK The adjustment screw NOTE When returning to normal mode do not forget to reset the shunt motor to its original position by turning the change-over switch to "A". If the operating disturbance cannot be rectified by means of the above an installation engineer should be called. If necessary set the switch to "reserve mode" (manual shunt operation necessary). 28

31 Miscellaneous Dealing with malfunctions Resetting the miniature circuit breakers The MCB (7) is accessible behind the cover and is located to the left of the panel. Normal mode of the miniature circuitbreaker is "1" (up). Fine wire fuse Automatic elements, charge pump (17) and its cabling are fuse-protected internally with a miniature circuit breaker (7), plus a fine-wire fuse (33) on the relay card (34). The fine-wire fuse may be replaced only once the fault has been rectified. Fine-wire fuse 2 AT, 5x20mm.Adefective fine-wire fuse is indicated by the operating mode indicator being off when the switch is set to NOTE Work behind covers secured by screws may only be carried out under the supervision of a qualified installation engineer. Alarm In the event of a communications error between and F20XX, the red LED (31) flashes. This malfunction will be noted as then switches to alarm operation if the outdoor temperature is lower than +5 C. This means 35 C boiler temperature and 15 C reference temperature at the flow line. At higher outdoor temperatures, only the reference value on the flow line is set to +15 C. In the event of an internal sensor error or a constant F20XX alarm, the red LED (31) lights continuously. This malfunction will be noted as then automatically switches to alarm operation (described above). 31 Alarm indication 29
