ACCAHUTUIONNG Immediate danger to life or danger of severe personal injury or significant damage to property. Note Risk of damage to property or minor personal injury or important information with no further risk of personal injury or damage to property. 1.2 Intended use This device is only intended for use as specified by the manufacturer. Any other use beyond that intended by the manufacturer is prohibited. This requires the user to abide by the relevant project planning documents. Please refrain from tampering with or altering the device. 1.3 Legal regulations and directives This heat pump is designed for use in a domestic environment according to Article 1, Paragraph 2 k) of EU directive 2006/42/EC (machinery directive) and is thus subject to the requirements of EU directive 2014/35/EU (low-voltage directive). It is thus also intended for use by non-professionals for heating shops, offices and other similar working environments, agricultural establishments and hotels, guesthouses and other residential buildings. This heat pump conforms to all relevant DIN/VDE regulations and EU directives. Refer to the EC Declaration of Conformity in the appendix for details. The heat pump must be connected to the power supply in compliance with all relevant VDE, EN and IEC standards. Any further connection requirements stipulated by local utility companies must also be observed. The heat pump is to be connected to the heat source system and the heating system in accordance with all applicable regulations. This unit can be used by children aged 8 and over and by persons with limited physical, sensory or mental aptitude or lack of experience and/or knowledge, providing they are supervised or have been instructed in the safe use of the unit and understand the associated potential dangers. Children must not play with the device. Cleaning and user maintenance must not be carried out by children without supervision. ACCAHUTUIONNG Work on the heat pump must only be performed by authorised and qualified after-sales service technicians! ACCAHUTUIONNG When operating or maintaining a heat pump, the legal requirements of the country where the heat pump is operated apply. Depending on the refrigerant fill quantity, the heat pump must be inspected for leaks at regular intervals by a certified technician, and these inspections must be recorded. More information can be found in the accompanying log book. 452237.66.06-EN · 04/2024 · Ext.Rei 2 83288602 Installation and operating instructions WWP S 26 ID - WWP S 35 ID 1 Safety notes 1.4 Energy-efficient use of the heat pump By operating this heat pump you are helping to protect our environment. Both the heating system and the heat source must be properly designed and dimensioned to ensure efficient operation. It is particularly important to keep water flow temperatures as low as possible. All connected heat consumers should therefore be suitable for low flow temperatures. Raising the heating water temperature by 1 K corresponds to an increase in electricity consumption of approx. 2.5 %. Low-temperature heating systems with flow temperatures between 30 °C and 50 °C are particularly well-suited for energy-efficient operation. 452237.66.06-EN · 04/2024 · Ext.Rei 3 83288602 Installation and operating instructions WWP S 26 ID - WWP S 35 ID 2 Intended use of the heat pump 2 Intended use of the heat pump 2.1 Intended purpose The brine-to-water heat pump is to be used exclusively for the heating of heating water. It can be used in new or existing heating systems. A mixture of water and frost protection (brine) is used as a heat transfer medium in the heat source system. Borehole heat exchangers, ground heat collectors or similar systems can be used as the heat source system. 2.2 Operating principle The heat generated by the sun, wind and rain is stored in the ground. This heat stored in the ground is collected at a low temperature by the brine circulating in the ground heat collector, the borehole heat exchanger or a similar system. Diese Erdwärme wird von der Erdsonde oder Ähnlichem von der Sole bei niedriger Temperatur aufgenommen. A circulating pump then conveys the "heated" brine to the evaporator of the heat pump. There the heat is given off to the refrigerant in the refrigeration circuit. This cools the brine so that it can once again absorb thermal energy in the brine circuit. The refrigerant is drawn in by the electrically driven compressor, compressed and "pumped" to a higher temperature level. The electrical power needed to run the compressor is not lost in this process. Most of it is absorbed by the refrigerant. The refrigerant subsequently passes through the liquifier where it transfers its thermal energy to the heating water. Depending on the set operating point, the heating water can thus be heated up to a max. of 62 °C. 452237.66.06-EN · 04/2024 · Ext.Rei 4 83288602 Installation and operating instructions WWP S 26 ID - WWP S 35 ID 3 Basic device 3 Basic device The basic device consists of a heat pump for indoor installation wired ready for use with metal casing, switch box and integrated heat pump manager. The refrigeration circuit is "hermetically sealed" and contains the fluorinated refrigerant R410A included in the Kyoto protocol. Information on the GWP value and CO2 equivalent of the refrigerant can be found in the chapter Device information. The refrigerant is CFC-free, nonozone depleting and non-combustible. All components required for the operation of the heat pump are located in the switch box. An outside temperature sensor including fixing accessories and a dirt trap are supplied with the heat pump. The supply for the supply voltage and the control voltage must be installed by the customer. The circulating pumps (brine and heating water side) included in the scope of supply must be installed in accordance with the hydraulic diagrams or the development documents. The electrical connection of the circulating pumps must be established in accordance with Cap. 7.5.3 on page 15. The customer must provide both the heat source system and the brine circuit manifold. 1. Switch box 2. Evaporator 3. Liquefier 4. Filter dryer 5. Compressor 1 6. Compressor 2 7. Expansion valve 8.

Operation and menu navigation are identical to those of the heat pump manager. Connection takes place via an interface (special accessories) with RJ 12 Western plug. Note In the case of heating controllers with a removable control panel, this can also be used directly as a remote display. 4.3 Building management system The heat pump manager can be connected to a building management system network via supplementation of the relevant interface plug-in card. The supplementary installation instructions of the interface card must be consulted regarding the exact connection and parameterisation of the interface. The following network connections can be made on the heat pump manager: Modbus EIB, KNX Ethernet ACCAHUTUIONNG If the heat pump or circulating pumps are controlled externally, a flow rate switch is required to prevent the compressor from being switched on when there is no volume flow. 452237.66.06-EN · 04/2024 · Ext.Rei 6 83288602 max. 45° Installation and operating instructions WWP S 26 ID - WWP S 35 ID 5 Transport 5 Transport A lift truck is suited for transporting the unit on a level surface. Carrying straps may be used if the heat pump needs to be trans-ported on an uneven surface or carried up or down stairs. These straps can be passed directly underneath the pallet. ACCAHUTUIONNG The heat pump must not be tilted more than 45° (in any direction). Use the holes provided in the sides of the frame to lift the unit without the pallet. The side panel assemblies must be removed for this purpose. Any commercially available length of pipe can be used as a carrying aid. After transportation, the transport fastening in the device is to be removed from both sides of the base. X X ACCAHUTUIONNG Before commissioning, the transport fastening must be removed. 452237.66.06-EN · 04/2024 · Ext.Rei 7 83288602 Installation and operating instructions WWP S 26 ID - WWP S 35 ID 5 Transport All panelling can be removed to allow accessing the inside of the device. Loosen the screws for this purpose.

The entire base of the frame should lie directly on the floor to ensure an adequate soundproof seal. If this is not the case, additional sound insulation measures may be necessary. The heat pump must be installed so that maintenance work can be carried out without hindrance. This can be ensured by maintaining a clearance of approx. 1 m in front of the heat pump. 0,3 m 0,5 m 1,0 m Neither frost nor temperatures higher than 35? must occur in the installation location at any time of the year. Note The heat pump is not intended for use over 2000 metres above sea level. 6.2 Acoustic Emissions The heat pump operates silently due to efficient sound insulation. Internal insulation measures should be carried out to prevent vibrations from being transmitted to the foundation or to the heating system. 452237.66.06-EN · 04/2024 · Ext.Rei 9 83288602 Installation and operating instructions WWP S 26 ID - WWP S 35 ID 7 Installation 7 Installation 7.1 General The following connections need to be established on the heat pump. The hydraulic integration diagram must be adhered to: Flow and return of the brine (heat source system) Flow and return of the heating system Temperature sensor Voltage supply 7.2 Connection on the heating side ACCAHUTUIONNG Flush the heating system prior to connecting the heat pump. Before connecting the heating water system to the heat pump, the heating system must be flushed to remove any impurities, residue from sealants, etc. Any accumulation of deposits in the liquifier could cause the heat pump to completely break down. Once the heat pump has been connected to the heating system, it must be filled, deaerated and pressure-tested. ACCAHUTUIONNG The maximum test pressure in the heating circuit and the brine circuit is 6.0 bar. This value must not be exceeded. The following points must be observed when filling the system: Untreated filling water and make-up water must be of drinking water quality. (colourless, clear, free of sediments) Filling water and make-up water must be pre-filtered (max. pore size 5 µm). Scale formation in domestic hot water heating systems cannot be avoided, but in systems with flow temperatures below 60 °C, the problem can be disregarded. With hightemperature heat pumps and in particular with bivalent systems in the higher performance range (heat pump + boiler combination), flow temperatures of 60 °C and more can be achieved. The following standard values should therefore be adhered to with regard to the filling and make-up water according to VDI 2035, sheet 1: The total hardness values can be found in the table. Total heat output in kW Total alkaline earths in mol/m³ and/or mmol/l < 50 50 - 200 200 - 600 > 600 2.0 2.0 1.5 < 0.02 Specific system volume (VDI 2035) in l/kW < 20 20 < 50 50 Total hardness in °dH 16.8 11.2 11.2 8.4 < 0.111 8.4 < 0.111 < 0.111 1. This value lies outside the permissible value for heat exchangers in heat pumps. Fig. 7.1:Guideline values for filling and make-up water in accordance with VDI 2035 For systems with an above-average specific system volume of 50 l/kW, VDI 2035 recommends using fully demineralized water and a pH stabiliser to minimize the risk of corrosion in the heat pump and the heating system. ACCAHUTUIONNG With fully demineralized water, it is important to ensure that the minimum permissible pH value of 7.5 (minimum permissible value for copper) is complied with. Failure to comply with this value can result in the heat pump being destroyed. 452237.66.06-EN · 04/2024 · Ext.Rei 10 83288602 Installation and operating instructions WWP S 26 ID - WWP S 35 ID 7 Installation Minimum heating water flow rate The minimum heating water flow rate through the heat pump must be assured in all operating states of the heating system. This can be accomplished, for example, by installing a dual differential pressureless manifold. The frost protection function of the heat pump manager is active whenever the heat pump manager and the heat circulating pumps are ready for operation. The system must be drained if the heat pump is taken out of service or in the event of a power failure. If heat pump systems are implemented in buildings where a power failure cannot be detected (holiday homes etc.), the heating circuit should be operated with suitable frost protection. 7.3 Heat source connection The following procedure must be observed when making the connection: Connect the brine pipe to the heat source flow and return of the heat pump. The hydraulic integration diagram must be adhered to. ACCAHUTUIONNG The supplied dirt trap must be inserted in the heat source inlet of the heat pump to protect the evaporator against the ingress of impurities. The brine must be produced prior to charging the system. The brine concentration must be at least 25 %. This guarantees frost protection up to approx. -14 °C. Only monoethylene glycol or propylene glycol-based antifreeze may be used. The heat source system must be de-aerated and checked for leaks. ACCAHUTUIONNG The brine must contain at least a 25 % concentration of a monoethylene glycol or propylene glycol-based antifreeze, which must be mixed before filling. Note If necessary, the operating range can be extended to a brine inlet temperature of 10 °C. In this case, the minimum brine concentration must be adjusted to 30 %. (Freezing temperature -17 C°). ACCAHUTUIONNG The maximum test pressure in the heating circuit and the brine circuit is 6.0 bar. This value must not be exceeded. ACCAHUTUIONNG A suitable de-aerator (micro bubble air separator) must be installed in the heat source circuit by the customer. 452237.66.06-EN · 04/2024 · Ext.Rei 11 83288602 Installation and operating instructions WWP S 26 ID - WWP S 35 ID 7 Installation 7.4 Temperature sensor The following temperature sensors are already installed or must be installed additionally: Outside temperature sensor (R1) supplied (NTC-2) Return temperature secondary circuit (R2) installed (NTC-10) Return temperature primary circuit (R24) installed (NTC-10) Flow temperature secondary circuit (R9) installed (NTC-10) Flow temperature primary circuit (R6) installed (NTC-10) 7.4.1 Sensor characteristic curves Temperature in °C NTC-2 in k NTC-10 in k -20 -15 -10 -5 0 5 10 14.6 11.4 8.9 7.1 5.6 4.5 3.7 67.7 53.4 42.3 33.9 27.3 22.1 18.0 15 20 25 30 35 40 45 50 55 60 2.9 2.4 2.0 1.7 1.4 1.1 1.0 0.8 0.7 0.6 14.9 12.1 10.0 8.4 7.0 5.9 5.0 4.2 3.6 3.1 The temperature sensors to be connected to the heat pump manager must correspond to the sensor characteristic curve illustrated in Fig. 7.2 on page 12.

Mount on the external wall on the north or north-west side where possible Do not install in a "sheltered position" (e.g. in a wall niche or under a balcony) Not in the vicinity of windows, doors, exhaust air vents, external lighting or heat pumps Not to be exposed to direct sunlight at any time of year - Dimensioning parameter sensor lead Conductor material Cu Cable-length 50 m Ambient temperature 35 °C Laying system B2 (DIN VDE 0298-4 / IEC 60364-5-52) External diameter 4-8 mm 7.4.3 Installing the strap-on sensor It is only necessary to mount the strap-on sensors if they are included in the scope of supply of the heat pump but have not yet been installed. The strap-on sensors can be fitted as pipe-mounted sensors or installed in the immersion sleeve of the compact manifold. Mounting as a pipe-mounted sensor Remove paint, rust and scale from heating pipe. Coat the cleaned surface with heat transfer compound (apply sparingly). Attach the sensor with a hose clip (tighten firmly, as loose sensors can cause mal- functions) and thermally insulate. Hose clip Thermal insulation Strap-on sensor 7.4.4 Hydraulic distribution system The compact manifold and the dual differential pressureless manifold function as an interface between the heat pump, the heating distribution system, the buffer tank and, in some cases, even the domestic hot water cylinder. A compact system is used to simplify the installation process, so that a lot of different components do not have to be installed individually. Further information can be found in the relevant installation instructions. 452237.66.06-EN · 04/2024 · Ext.Rei 13 83288602 Installation and operating instructions WWP S 26 ID - WWP S 35 ID 7 Installation 7.5 Electrical connection 7.5.1 General All electrical installation work must be carried out by a trained electrician or a specialist for the specified tasks in accordance with the installation and operating instructions, country-specific installation regulations (e.g. VDE 0100), technical connection conditions of the energy suppliers and supply grid operators (e.g. TAB) and local conditions. To ensure that the frost protection function of the heat pump works properly, the heat pump manager must remain connected to the power supply and the flow must be maintained through the heat pump at all times. The switching contacts of the output relay are interference-suppressed. Therefore, depending on the internal resistance of the measuring instrument, a voltage can also be measured when the contacts are open. However, this will be much lower than the line voltage. Extra-low voltage is connected to controller terminals N1-J1 to N1-J11; N1-J19 to N1J20; N1-J23 to N1-J26 and the terminal strips X3. If, due to a wiring error, the line voltage is mistakenly connected to these terminals, the heat pump manager will be destroyed. Note For installation work on the switch box, ensure that the mains cable and signal cables are inserted separately into the switch box. The specially arranged switch box inlets must be used for this purpose (see Fig. 7.4 on page 14). The mains cables and signal cables must also always be laid separately in the switch box during wiring work. Supply signal cable Supply mains cable Fig. 7.4:Cable inlet switch box 7.5.2 Electrical installation work 1. The four-core electrical supply cable for the heat pump power part is fed from the heat pump electricity meter into the heat pump via the utility company blocking contactor (if required) (for supply voltage, see heat pump manual). The mains cable is connected to the heat pump contact plate via terminals X1: L1/ L2/L3/PE. ACCAHUTUIONNG Ensure that there is a clockwise rotating field: With incorrect wiring the starting of the heat pump is prevented. A corresponding warning is indicated on the display of the heat pump manager (adjust wiring). An all-pole disconnecting device with a contact gap of at least 3 mm (e.g. utility company blocking contactor or power contactor) and an all-pole circuit breaker with common tripping for all external conductors must be installed in the power supply for the heat pump (tripping current and characteristic in compliance with the device information). 452237.66.06-EN · 04/2024 · Ext.Rei 14 83288602 Installation and operating instructions WWP S 26 ID - WWP S 35 ID 7 Installation 2. The three-core supply cable for the heat pump manager (heating controller N1) is fed into the heat pump. Connection of the control cable to the contact plate of the heat pump via terminal X2: L/N/PE. The (L/N/PE~230 V, 50 Hz) supply cable for the heat pump manager must have a continuous voltage. For this reason, it should be tapped upstream from the utility company blocking contactor or be connected to the household current, as important protection functions could otherwise be lost during a utility block. 3. The utility company blocking contactor (K22) with main contacts and an auxiliary contact must be designed and provided by the customer in accordance with the heat pump output. The NO contact of the utility company blocking contactor is looped from the terminal strip X3/G to the plug-in terminal X3/ID3. CAUTION! Extra-low voltage! 4. The contactor (K20) for the immersion heater (E10) of mono energy systems (HG2) should be dimensioned according to the radiator output and must be supplied by the customer. It is controlled (230 V AC) by the heat pump manager via terminals X2/N and X2/K20. 5. The contactor (K21) for the flange heater (E9) in the domestic hot water cylinder should be dimensioned according to the radiator output and must be supplied by the customer. It is controlled (230 V AC) by the heat pump manager via terminals X2/N and X2/K21. 6. The contactors mentioned above in points 3, 4 and 5 are installed in the electrical distribution system. 7. All installed electric cables must have permanent wiring. 8. The heat circulating pump (M13) is activated via the contact N1-J13/NO5. The connection points for the pump are X2/M13 and X2/N. When using pumps where the switching capacity exceeds the output, a coupling relay must be interposed. 9. The auxiliary circulating pump (M16) is activated via the contact N1-J16/NO9. The connection points for the pump are X2/M16 and X2/N. A coupling relay is already integrated in this output. 10. The domestic hot water circulating pump (M18) is activated via the contact N1J13/NO6. The connection points for the pump are X2/M18 and X2/N. When using pumps where the switching capacity exceeds the output, a coupling relay must be interposed. 11. The brine or well pump (M11) is activated via the contact N1-J12/NO3. The connection points for the pump are X2/M11 and X2/N. A coupling relay is already integrated in this output. 12. The return sensor (R2) is integrated in the heat pumps for indoor installation. The heat pump manager is connected via the following terminals: X3/GND and X3/ R2. 13. The external sensor (R1) is connected to terminals X3/GND and X3/R1. 14. The domestic hot water sensor (R3) is included with the domestic hot water cylinder and is connected to terminals GND and X3/R3. 7.5.3 Connection of electronically regulated circulating pumps Electronically regulated circulating pumps have high starting currents, which may shorten the service life of the heat pump manager. For this reason, a coupling relay is installed or must be installed between the output of the heat pump manager and the electronically regulated circulating pump. This is not necessary if the permissible operating current of 2 A and a maximum starting current of 12 A are not exceeded in the electronically regulated circulating pump or if express approval has been issued by the pump manufacturer. ACCAHUTUIONNG It is not permitted to connect more than one electronically regulated circulating pump via a relay output. 452237.66.06-EN · 04/2024 · Ext.Rei 15 83288602 Installation and operating instructions WWP S 26 ID - WWP S 35 ID 8 Commissioning 8 Commissioning 8.1 General Information To ensure that commissioning is performed correctly, it should only be carried out by an after-sales service technician (Weishaupt-Techniker) authorised by the manufacturer. This may be a condition for an additional guarantee . 8.2 Preparation The following items must be checked prior to commissioning: All of the heat pump connections must be installed as described in chapter 7. The heat source system and the heating circuit must have been filled and checked. The dirt trap must be inserted in the brine inlet of the heat pump. All valves that could impair proper flow in the brine and heating circuits must be open. The heat pump manager must be adapted to the heating system in accordance with the controller's operating instructions. The hydraulic network must be flushed correctly before installing the heat pump. This includes the supply line to the heat pump. Only when flushing is complete can the heat pump be hydraulically integrated. The dirt traps present as standard or included for assembly must be inspected between 4 and 8 weeks after the heat pump is commissioned or changes made to the heating system and cleaned if necessary. Further maintenance intervals must be scheduled depending on the level of soiling, which must be defined and carried out by a suitably qualified person. Special notes for the integration of heat pumps in existing systems (renovations): The existing heat distribution network (pipe materials, connection types, etc.) and the existing heating systems (e.g. radiators, underfloor heating, etc.) can impact the quality of the water in existing systems. Particularly when welded steel pipes or pipes that are not oxygen diffusion-proof are used, deposits, scaling, silting or similar may be present that can cause damage in the heat pump system. This can result in a total failure of the heat pump The following measures must be observed to avoid this: Compliance with the water properties and water quality Flushing of the hydraulic system Maintenance interval of the dirt traps. If silting or ferromagnetic particles are to be expected in the hydraulic network, dirt separators or magnetite separators must be installed on-site before the medium enters the heat pump. The maintenance intervals must be defined by a suitably qualified person. 8.3 Commissioning procedure The heat pump is commissioned via the heat pump manager. ACCAHUTUIONNG Start-up must be performed in accordance with the installation and operating instructions of the heat pump manager. 452237.66.06-EN · 04/2024 · Ext.Rei 16 83288602 Installation and operating instructions WWP S 26 ID - WWP S 35 ID 9 Cleaning / maintenance 9 Cleaning / maintenance 9.1 Maintenance To prevent faults due to sediment in the heat exchangers, care must be taken to ensure that no impurities can enter either the heat source system or the heating system. In the event that operating malfunctions due to contamination occur nevertheless, the system should be cleaned as described below. 9.2 Cleaning the heating system The ingress of oxygen into the heating water circuit may result in the formation of oxidation products (rust), particularly if steel components are used. These enter the heating system via the valves, the circulating pumps and/or plastic pipes. A diffusion-resistant installation is therefore essential, especially with regard to the piping of underfloor heating systems. Note We recommend the installation of a suitable corrosion protection system to prevent the formation of deposits (e.g. rust) in the condenser of the heat pump. Residue from lubricants and sealants may also contaminate the heating water. In the event of severe contamination leading to a reduction in the performance of the liquefier in the heat pump, the system must be cleaned by a heating technician. Based on current information, we recommend using a 5 % phosphoric acid solution for cleaning purposes. However, if cleaning needs to be performed more frequently, a 5 % formic acid solution should be used. In both cases, the cleaning fluid should be at room temperature. We recommend flushing the heat exchanger in the direction opposite to the normal flow direction. To prevent acidic cleaning agents from entering the heating system circuit, we recommend connecting the flushing device directly to the flow and return of the liquefier of the heat pump. It is then important that the system be thoroughly flushed using appropriate neutralising agents to prevent any damage from being caused by cleaning agent residue remaining in the system. Acids must be used with care and the regulations of the employers liability insurance associations must be adhered to. The instructions of the cleaning agent manufacturer must always be observed. 9.3 Cleaning the heat source system ACCAHUTUIONNG The supplied dirt trap must be inserted in the heat source inlet of the heat pump to protect the evaporator against the ingress of impurities. The filter sieve of the dirt trap should be cleaned one day after start-up. Further checks must be set according to the level of dirt. If no more signs of contamination are evident, the filter can be removed to reduce pressure drops. 452237.66.06-EN · 04/2024 · Ext.Rei 17 83288602 Installation and operating instructions WWP S 26 ID - WWP S 35 ID 10 Faults / troubleshooting 10 Faults / troubleshooting This heat pump is a quality product and is designed for trouble-free operation.
