12 4 Pipe cnectis General Pipe installati must be carried out in accordance with current norms and directives. F1155PC can operate with a return temperature of up to 58 C and an outgoing temperature from the heat pump of 70 (65 C with ly the compressor). F1155PC is not equipped with external shut valves; these must be installed to facilitate any future servicing. Cauti Ensure that incoming water is clean. When using a private well, it may be necessary to supplement with an extra water filter. Cauti Any high points in the climate system, must be equipped with air vents. System diagram F1155PC csists of heat pump, immersi heater, circulati pumps and ctrol system. F1155PC is cnected to the brine and heating medium circuits. In the heat pump evaporator, the brine (water mixed with anti-freeze, glycol or ethanol) releases its energy to the refrigerant, which is vaporised in order to be compressed in the compressor. The refrigerant, of which the temperature has now been raised, is passed to the cdenser where it gives its energy to the heating medium circuit and, if necessary, to any docked water heater. If there is a greater need for heating/hot water than the compressor can provide there is an integrated immersi heater. The brine can also be circulated via a mixing valve to a heat exchanger. There the brine cools the heating system's water so that comfort cooling can be maintained during the hotter periods of the year. XL1 XL6 XL9 XL7 XL2 The pipe system needs to be flushed out before the heat pump is cnected so that debris cannot damage compent parts. The climate system must be adjusted for both heating and cooling operati.

13 Dimensis and pipe cnectis Brine side Collector Cauti 70 The length of the collector hose varies depending the rock/soil cditis, climate ze and the climate system (radiators or underfloor heating). 725* * Max length per coil for the collector should not exceed 400 m. In those cases where it is necessary to have several collectors, these should be cnected in parallel with the possibility for adjusting the flow of the relevant coil. For surface soil heat, the hose should be buried at a depth determined by local cditis and the distance between the hoses should be at least 1 metre. For several bore holes, the distance between the holes must be determined according to local cditis. Ensure the collector hose rises cstantly towards the heat pump to avoid air pockets. If this is not possible, airvents should be used. As the temperature of the brine system can fall below 0 C, it must be protected against freezing down to -15 C. When making the volume calculati, 1 litre of ready mixed brine per meter of collector hose (applies when using PEM-hose 40x2.4PN 6.3) is used as a guide value. XL1 XL6 XL9 XL7 XL2 Side cnecti It is possible to angle the brine cnectis, for cnecti to the side instead of top cnecti. To angle out a cnecti: 1. Discnect the pipe at the top cnecti. 2. Angle the pipe in the desired directi. 3. If necessary, cut the pipe to the desired length.

The level vessel must be installed at the highest point in the brine system, the incoming pipe before the brine pump (Alt. 1). If the level vessel cannot be placed at the highest point, an expansi vessel must be used (Alt. 2). Note that cdensati may drip from the level vessel. Positi the vessel so that this does not harm other equipment. Details of the antifreeze used must be shown the level vessel. Install the enclosed safety valve under the level vessel as illustrated. The entire length of the overflow water pipe from the safety valve must be inclined to prevent water pockets and must also be frost-free. * Can be angled for side cnecti. Chapter 4 Pipe cnectis 13

14 Install shut valves as close to the heat pump as possible. Fit the supplied particle filter the incoming pipe. In the case of cnecti to an open groundwater system, an intermediate frost-protected circuit must be provided, because of the risk of dirt and freezing in the evaporator. This requires an extra heat exchanger. Alt. 1 Alt. 2 P Water heater Cnecting the hot water heater If F1155PC is not docked to a water heater or if it is to work with fixed cdensing, the cnecti for the water heater (XL9) must be plugged. Any docked hot water heater must be fitted with necessary set of valves. The mixing valve must be installed if the setting is changed so that the temperature can exceed 60 C. Collector XL6 XL7 Heating medium side Cnecting the climate system A climate system is a system that regulates indoor comfort with the help of the ctrol system in F1155PC and for example radiators, underfloor heating/cooling, fan cvectors etc. Install all required safety devices, shut- valves (as close to the heat pump as possible), and supplied particle filter. The safety valve must have a maximum 0.25 MPa (2.5 bar) opening pressure and be installed the heating medium return as illustrated. The entire length of the overflow water pipe from the safety valves must be inclined to prevent water pockets and must also be frost proof. When cnecting to a system with thermostats all radiators, a relief valve must be fitted, or some of the thermostats must be removed to ensure sufficient flow. The setting for hot water is made in menu The safety valve must have a maximum opening pressure of 1.0 MPa (10.0 bar) and be installed the incoming domestic water line as illustrated. The entire length of the overflow water pipe from the safety valve must be inclined to prevent water pockets and must also be frost-free. Cauti Hot water producti is activated in menu 5.2 or in the start guide. Fixed cdensing If F1155PC is to work towards the water heater with fixed cdensing you must cnect an external flow sensor (BT25) according to the descripti page 20.

Further opti informati is available at and in the respective assembly instructis for the accessories used. See page 57 for a list of the accessories that can be used with F1155PC. 14 Chapter 4 Pipe cnectis

15 T Buffer vessel If the climate system volume is too small for the heat pump output, the radiator system can be supplemented with a buffer vessel, for example NIBE UKV. UKV Ventilati recovery The installati can be supplemented with the exhaust air module FLM to provide ventilati recovery. Pipes and other cold surfaces must be insulated with diffusi-proof material to prevent cdensati. The brine system must be supplied with a pressure expansi vessel (CM3). If there is a level vessel (CM2) this should be replaced. Extract Avluft air Ø 160 Exhaust air Frånluft Ø 160 T FLM P Ground water system An intermediate heat exchanger is used to protect the heat pump's exchanger from dirt. The water is released into a buried filtrati unit or a drilled well. See page 25 for more informati about cnecting a ground water pump. If this docking alternative is used, "min. brine out" in menu "br pmp al set." must be changed to a suitable value to prevent freezing in the heat exchanger. Under floor heating systems The external circulati pump is dimensied for the under floor heating system s demand. To ensure a heating supply during hot water producti, the heating system can be supplemented with a NIBE UKV vessel, e.g. when there is a water coil in the FTX ventilati. UKV Chapter 4 Pipe cnectis 15

16 T T Two or more climate systems When more than e climate system, with a lower temperature, is to be heated up, the following cnecti can be used. The shunt valve lowers the temperature to, for example, the under floor heating system. The ECS 40/ECS 41 accessory is required for this cnecti. Pool Charging of the pool is ctrolled by the pool sensor. In the case of low pool temperatures, the shuttle valve reverses directi and opens towards the pool exchanger. The POOL 40 accessory is required for this cnecti. Pool 16 Chapter 4 Pipe cnectis

17 5 Electrical cnectis General All electrical equipment, except the outdoor sensors, room sensors and the current sensors are ready cnected at the factory. Discnect the heat pump before insulati testing the house wiring. If the building is equipped with an earth-fault breaker, F1155PC should be equipped with a separate e. If a miniature circuit breaker is used this should have at least motor characteristic C. See page 60 for fuse size. Electrical wiring diagrams for the heat pump, see separate installati handbook for electrical wiring diagrams. Communicati and sensor cables to external cnectis must not be laid close to high current cables. The minimum area of communicati and sensor cables to external cnectis must be 0.5 mm² up to 50 m, for example EKKX or LiYY or equivalent. When cable routing in F1155PC, cable grommets (e.g. UB1-UB3, marked in image) must be used. In UB1-UB3 the cables are inserted through the heat pump from the back to the frt. The switch (SF1) must not be moved to "" or " " until the boiler has been filled with water. Compent parts of the product can be damaged.

20 Outside sensor Install the outdoor temperature sensor (BT1) in the shade a wall facing north or north-west, so it is unaffected by the morning sun for example. Cnect the sensor to terminal block X6:1 and X6:2 the input board (AA3). Use a twin core cable of at least 0.5 mm² cable area. If a cduit is used it must be sealed to prevent cdensati in the sensor capsule. F1155PC External AA3-X BT1 Temperature sensor, hot water charging The temperature sensor, hot water charging (BT6) is placed in the submerged tube the water heater. Cnect the sensor to terminal block X6:7 and X6:8 the input card (AA3). Use a 2 core cable of at least 0.5 mm² cable area. Hot water charging is activated in menu 5.2 or in the start guide. F1155PC F1145 AA3-X Room sensor F1155PC is supplied with a room sensor enclosed (BT50). The room sensor has up to three functis: 1. Show current room temperature in F1155PC's display. 2. Opti of changing the room temperature in C. 3. Makes it possible to change/stabilise the room temperature. Install the sensor in a neutral positi where the set temperature is required. A suitable locati is a free inner wall in a hall approx. 1.5 m above the floor. It is important that the sensor is not obstructed from measuring the correct room temperature by being located, for example, in a recess, between shelves, behind a curtain, above or close to a heat source, in a draft from an external door or in direct sunlight. Closed radiator thermostats can also cause problems. The heat pump operates without the sensor, but if e wishes to read the accommodati's indoor temperature in F1155PC's display, the sensor must be installed. Cnect the room sensor to X6:3 and X6:4 the input board (AA3). If the sensor is to be used to change the room temperature in C and/or to change/stabilise the room temperature, the sensor must be activated in menu If the room sensor is used in a room with underfloor heating, it should ly have an indicatory functi, not ctrol of the room temperature. F1155PC F1145 External RG05 AA3-X BT6 Temperature sensor, hot water top A temperature sensor for hot water top (BT7) can be cnected to F1155PC via soft inputs for showing the water temperature at the top of the tank.

It can be set to 35 (pre-set, for example under floor heating) or 45 C (for example radiators) LEK Optial cnectis x230V for F1155PC Load mitor When many electrical appliances are cnected in the property at the same time as the electric additial heat is operating, there is a risk of the property's main fuse tripping. The heat pump has integrated load mitors that ctrol the electrical steps for the electrical additi by redistributing the power between the different phases or disengaging the electrical additi in event of overload in a phase. If the overload remains despite the electrical additi being disengaged, the compressor winds down. Recnecti occurs when other current csumpti is reduced Cnecting current sensors A current sensor should be installed each incoming phase cductor in to the distributi box to measure the current. The distributi box is an appropriate installati point. 1x230V and 3x400V for F1155PC ON Cnect the current sensors to a multi-core cable in an enclosure next to the electrical distributi unit. The multi-core cable between the enclosure and the heat pump must have a cable area of at least 0.5 mm².

32 Cauti When making fine adjustments of the indoor temperature, the curve must be set up or down instead, this is de in menu 1.1 temperature. Curve set An set of the curve means that the supply temperature changes by the same amount for all the outdoor temperatures, e.g. that a curve set of +2 steps increases the supply temperature by 5 C at all outdoor temperatures. Flow line temperature maximum and minimum values Because the flow line temperature cannot be calculated higher than the set maximum value or lower than the set minimum value the heating curve flattens out at these temperatures. Cauti Under floor heating systems are normally max flow line temperature set to between 35 and 45 C. Must be restricted with underfloor cooling min. flow line temp. to prevent cdensati. Check the max temperature for your floor with your installer/floor supplier. 4. You can now select to take read outs for different outdoor temperatures by turning the ctrol knob to the right or left and read the correspding flow temperature. 5. Press the OK or Back butt to exit read mode. TIP Wait 24 hours before making a new setting, so that the room temperature has time to stabilise. If it is cold outdoors and the room temperature is too low, increase the curve slope by e increment. If it is cold outdoors and the room temperature is too high, lower the curve slope by e increment. If it is warm outdoors and the room temperature is too low, increase the curve set by e increment. If it is warm outdoors and the room temperature is too high, lower the curve set by e increment. 32 The figure at the end of the curve indicates the curve slope.

55 10 Disturbances in comfort In most cases, the heat pump notes operatial interference (operatial interference can lead to disturbance in comfort) and indicates this with alarms and shows acti instructis in the display. Info menu All the heat pump measurement values are gathered under menu 3.1 in the heat pump menu system. Looking through the values in this menu can often simplify finding the source of the fault. See help menu or user manual for more informati about menu 3.1. Manage alarm alarm info / acti reset alarm aid mode Low pressure alarm In the event of an alarm, some kind of malfuncti has occurred, which is indicated by the status lamp changing from green ctinuously to red ctinuously. In additi, an alarm bell appears in the informati window. Alarm In the event of an alarm with a red status lamp a malfuncti has occurred that the heat pump cannot remedy itself. In the display, by turning the ctrol knob and pressing the OK butt, you can see the type of alarm it is and reset it. You can also choose to set the heat pump to aid mode. info / acti Here you can read what the alarm means and receive tips what you can do to correct the problem that caused the alarm. reset alarm In most cases it is enough to select "reset alarm" to correct the problem that caused the alarm. If a green light illuminates after selecting "reset alarm" the alarm has been remedied. If a red light is still visible and a menu called alarm is visible in the display, the problem that caused the alarm remains. If the alarm disappears and then returns, see the troubleshooting secti (page 55). aid mode aid mode is a type of emergency mode. This means that the heat pump produces heat and/or hot water despite there being some kind of problem. This can mean that the heat pump's compressor is not running. In this case the immersi heater produces heat and/or hot water. To select aid mode an alarm acti must be selected in the menu Cauti Selecting "aid mode is not the same as correcting the problem that caused the alarm. The status lamp will therefore ctinue to be red.
