14 4 Pipe cnectis General Pipe installati must be carried out in accordance with current norms and directives. F1155 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). F1155 is not equipped with external shut valves; these must be installed to facilitate any future servicing. Cauti Any high points in the climate system, must be equipped with air vents. The pipe system needs to be flushed out before the heat pump is cnected so that debris cannot damage compent parts. System diagram F1155 csists of heat pump, immersi heater, circulati pumps and ctrol system. F1155 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.

15 Dimensis and pipe cnectis Brine side Collector Cauti The length of the collector hose varies depending the rock/soil cditis, climate ze and the climate system (radiators or underfloor heating) and the heating requirement of the building Each installati must be sized individually. 725* * 620 XL1 XL6 XL9 XL7 440 XL 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 brine system can fall below 0 C it must be protected against freezing down to -15 C. 1 litre of ready mixed brine per meter of collector hose (applies when using PEM-hose 40x 2.4 PN 6.3) is used as a guide value when making the volume calculati.

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. 70 Cnecting the brine side Insulate all indoor brine pipes against cdensati. The level vessel must be installed as 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). (XL6)/(XL7) Brine in/out ext Ø (mm) 28 Note that cdensati may drip from the level vessel.

16 Install the supplied safety valve under the level vessel 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. Install shut valves as close to the heat pump as possible. Fit the supplied particle filter the incoming pipe. T 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 Collector XL6 XL7 Water heater Cnecting the hot water heater 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 F1155 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. If F1155 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. The setting for hot water is made in menu The safety valve must have a maximum 1.0 MPa (10.0 bar) opening pressure and be installed the incoming domestic water line 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. Cauti Hot water producti is activated in menu 5.2 or in the start guide. 16 Chapter 4 Pipe cnectis

17 Fixed cdensing If F1155 is to work towards the water heater with fixed cdensing you must cnect an external flow sensor (BT25) according to the descripti page 22. In additi, you must perform the following menu settings. Menu min. flow line temp. heating max flow line temperature op. mod heat med pump op. mode Docking alternatives Menu setting (local variatis may be required) Desired temperature in the tank. Desired temperature in the tank. intermittent manual F1155 can be cnected in several different ways, some of which are shown below. Further opti informati is available at and in the respective assembly instructis for the accessories used. See page 61 for a list of the accessories that can be used with F1155. 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 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 28 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. 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 FLM T P Chapter 4 Pipe cnectis 17

18 T Free cooling The installati can be supplemented with fan cvectors, for example, in order to allow cnectis for free cooling (PCS 44). Pipes and other cold surfaces must be insulated with diffusi-proof material to prevent cdensati. Where the cooling demand is high, fan cvectors with drip trays and drain cnecti are needed. The brine system must be supplied with a pressure expansi vessel (CM3). If there is a level vessel (CM2) this should be replaced. 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. Fan cvectors Fläktkvektor P T 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 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 T 18 Chapter 4 Pipe cnectis

19 F 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, F1155 should be equipped with a separate e. If a miniature circuit breaker is used this should have at least motor characteristic C. See page 64 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 F1155, 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. Miniature circuit-breaker The heat pump operating circuit and a large proporti of its internal compents are internally fused by a miniature circuit breaker (FA1). Temperature limiter The temperature limiter (FD1) cuts the power to the electric additial heat if the temperature exceeds 89 C and is reset manually. Resetting The temperature limiter (FD1) is accessible behind the frt cover. Reset the temperature limiter by pressing the butt (FD1-SF2) using a small screwdriver. Accessibility, electrical cnecti The plastic cap of the electrical boxes is opened using a screwdriver. The cover for the input card is opened without a tool.

See page 27 for cnecting the sensor. Room sensor F1155 is supplied with a room sensor enclosed (BT50). The room sensor has up to three functis: 1. Show current room temperature in F1155'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. 22 Chapter 5 Electrical cnectis

23 The heat pump operates without the sensor, but if e wishes to read the accommodati's indoor temperature in F1155'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 under floor heating it should ly have an indicatory functi, not ctrol of the room temperature. AA3-X6 Cauti F1245 RG05 AA3-X F1155 External BT50 Changes of temperature in accommodati take time.

26 Optial cnectis 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. 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. Cnect the cable to the input board (AA3) terminal X4:1-4 block - where X4:1 is the comm terminal block for the three current sensors. The size of the property's main fuse is set in menu Inkommande Incoming electricity PEN L1 L 2 L 3 External cnecti optis F1155 has software ctrolled inputs and outputs the input card (AA3), for cnecting the external switch functi or sensor. This means that when an external switch functi or sensor is cnected to e of six special cnectis, the correct functi must be selected to the correct cnecti in the software in F1155. Cauti If an external switch functi or sensor is cnected to F1155, the functi to use input or output must be selected in menu 5.4, see page 50. Selectable inputs the input board for these functis are: AUX1 AUX2 AUX3 AUX4 AUX5 Selectable outputs are AA3:X7.

The additial heat and/or the compressor are discnected by cnecting a potential-free switch functi to the input selected in menu 5.4, see page 50. External blocking of additi and compressor can be combined. A closed ctact results in the electrical output being discnected. Ctact for external tariff blocking In those cases where external tariff blocking is used, it can be cnected to terminal block X6 the input board (AA3), which is positied behind the frt cover. Tariff blocking means that the additial heat, the compressor, the heating and hot water are blocked by cnecting a potential-free switch functi to the input selected in menu 5.4, see page 50. Closed switch means that tariff blocking is activated. When tariff blocking is activated, the min. supply line does not apply. Switch for "SG ready" This functi can ly be used in mains networks that support the "SG Ready"-standard. "SG Ready" requires two AUX inputs. In cases where this functi is required, it must be cnected to terminal block X6 the input card (AA3). "SG Ready" is a smart form of tariff ctrol where your electricity supplier can affect the indoor, hot water and/or pool temperatures (if applicable) or simply block the additial heat and/or compressor in the heat pump at certain times of the day (can be selected in menu after the functi is activated). Activate the functi by cnecting potential-free switch functis to two inputs selected in menu 5.4 (SG Ready A and SG Ready B), see page 50. Closed or open switch means e of the following: Blocking (A: Closed, B: Open) "SG Ready" is active. The compressor in the heat pump and additial heat is blocked like the day's tariff blocking. Normal mode (A: Open, B: Open) "SG Ready" is not active. No effect the system. Low price mode (A: Open, B: Closed) "SG Ready" is active. The system focuses costs savings and can for example exploit a low tariff from the electricity supplier or over-capacity from any own power source (effect the system can be adjusted in the menu 4.1.5). Overcapacity mode (A: Closed, B: Closed) "SG Ready" is active. The system is permitted to run at full capacity at over capacity (very low price) with the electricity supplier (effect the system is settable in menu 4.1.5). (A = SG Ready A and B = SG Ready B ) Switch for +Adjust Using +Adjust, the installati communicates with the underfloor heating's ctrol centre* and adjusts the heat curve and calculated supply temperature according to the underfloor heating system's recnecti. Activate the climate system you want +Adjust to affect by highlighting the functi and pressing the OK butt. *Support for +Adjust required +Adjust must first be selected in menu 5.4 soft inputs/outputs.

Switch for external blocking of heating In those cases where external blocking of heat is used, it can be cnected to terminal block X6 the input board (AA3), which is positied behind the frt cover. Heating operati is discnected by cnecting a potential-free switch functi to the input selected in menu 5.4, see page 50. A closed switch results in blocked heating operati. When heat blocking is activated, the min. supply line does not apply. Switch for external forced ctrol of brine pump In those cases external forced ctrol of brine pump is used, this can be cnected to terminal block X6 the input board (AA3), which is positied behind the frt cover. The brine pump can be force ctrolled by cnecting a potential free switch functi to the input selected in menu 5.4, see page 50. A closed switch means that the brine pump is active. Ctact for activati of temporary lux" An external switch functi can be cnected to F1155 for activati of the hot water functi "temporary lux". The switch must be potential-free and cnected to the selected input (menu 5.4, see page 50) terminal block X6 the input board (AA3). "temporary lux" is activated for the time that the ctact is cnected. Ctact for activati of external adjustment" An external ctact functi can be cnected to F1155 to change the supply temperature and the room temperature. When the switch is closed the temperature changes in C (if the room sensor is cnected and activated). If a room sensor is not cnected or activated, the desired change of "temperature" (heating curve set) with the number of steps selected is set. The value is adjustable between -10 and +10. climate system 1 The switch must be potential-free and cnected to the selected input (menu 5.4, see page 50) terminal block X6 the input board (AA3). The value for the change is set in menu 1.9.2, "external adjustment". climate system 2 to 8 External adjustment for climate systems 2 to 8 requires accessories ((ECS 40 or ECS 41).

32 Post adjustment and venting Pump adjustment, automatic operati Brine side To set the correct flow in the brine system, the brine pump must run at the correct speed. F1155 has a brine pump that can be automatically ctrolled in standard mode. Certain functis and accessories may require that they are run manually and the correct speed must then be set, see secti Pump adjustment, manual operati. This automatic ctrol occurs when the compressor is running and sets the speed of the brine pump to obtain the optimal temperature difference between the supply and return lines. For passive cooling operati, for example, the brine pump must run at a set speed, which is set in menu Heating medium side To set the correct flow in the heating medium system, the heating medium pump must run at the correct speed. F1155 has a heating medium pump that can be automatically ctrolled in standard mode. Certain functis and accessories may require that they are run manually and the correct speed must then be set, see secti Pump adjustment, manual operati. This automatic ctrol occurs when the compressor is running and sets the speed of the heating medium pump, for the present operating mode, to obtain the optimal temperature difference between the supply and return lines.

The next menu (heating curve/cooling curve) shows the heating and cooling curves for your house. The task of the curve is to give an even indoor temperature, regardless of the outdoor temperature, and thereby energy efficient operati. It is from these heat curves that the heat pump s ctrol computer determines the temperature of the water to the system, the supply temperature, and therefore the indoor temperature. Select the curve and read how the supply temperature changes at different outdoor temperatures here. The number to the far right of "system" displays which system you have selected the heating curve/cooling curve for. Curve coefficient The slopes of the heating /cooling curves indicate how many degrees the supply temperature is to be increased/reduced when the outdoor temperature drops/increases. A steeper slope means a higher supply temperature for heating or a lower supply temperature for cooling at a certain outdoor temperature C Outdoor UTETEMPERATUR temperature The optimum slope depends the climate cditis in your locati, if the house has radiators or under floor heating and how well insulated the house is. The curve is set when the heating installati is installed, but may need adjusting later. Normally, the curve will not need further adjustment. Cauti In the event of 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 as much 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 Underfloor heating systems are normally max flow line temperature set 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. The figure at the end of the curve indicates the curve slope. The figure beside the thermometer gives the curve set.

59 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 59). 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. 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. Troubleshooting If the operatial interference is not shown in the display the following tips can be used: Basic actis Start by checking the following possible fault sources: The switch's (SF1) positi.
