This heating characteristic curve can be adjusted to the individual temperatures requirements with the hotter / colder arrow keys in the main display. The plus key is used to increase the temperature, the bar display moves to the right. The minus key is used to reduce the temperature, the bar display moves to the left. For heating circuit 2/3, this setting takes place in the menu "2./3. Heat circuit". The set heating characteristic curves can be lowered or raised on a time-controlled basis. E.g. the heating characteristic curve can be lowered at night in poorly insulated buildings or excessive cooling of the heating surfaces can be prevented by raising heating characteristic curve before the shut-off time. If the raise and lower overlap, the raise function has priority. TIP For energy efficient operation of the heat pump heating system, the temperature level to be achieved by the heat pump should be as low as possible. In well-insulated buildings, an even heating operation without lower times usually results in lower energy costs, as power leaks with high flow temperatures are avoided and the same level of comfort is achieved with lower temperatures. Shut-off times can be compensated for with a raise - which commences approx. 1 hour before the shut-off time.

The desired domestic hot water temperature can be set in the menu "Hot water - Hot water setp. temperature". TIP Because the domestic hot water preparation takes place with high flow temperatures, which can result in high energy costs, it is advisable to adapt the domestic hot water preparation to the user behaviour. This can be achieved with domestic hot water set temperatures optimally adapted to the requirements, with corresponding domestic hot water lower times and a large hysteresis. Domestic hot water temperature HP maximum In order to achieve the highest possible heat pump proportion for domestic hot water preparation, the heat pump manager automatically determines the maximum achievable domestic hot water temperature in heat pump operation depending on the current heat source temperature. The lower the heat source temperature (e.g. outside temperature, brine temperature), the higher the achievable domestic hot water temperature. Domestic hot water preparation without flange heater If the domestic hot water set temperature is higher than the maximum domestic hot water temperature that can be achieved by the heat pump, the domestic hot water preparation is interrupted as soon as "HP maximum temperature" is reached. Domestic hot water preparation with flange heater If the domestic hot water set temperature is higher than the maximum domestic hot water temperature that can be achieved by the heat pump, the domestic hot water preparation takes place via the installed flange heater from the "HP maximum temperature". Reheating with flange heater After domestic hot water preparation with the heat pump, reheating for higher temperatures can take place with systems with a flange heater. The next domestic hot water heating only takes place once the temperature drops below the HP maximum temperature so that the basic heating can take place via the heat pump. Domestic hot water lower times Block times for the hot water heating can be programmed in the "Hot water lower times" menu item. During this time, the hot water heating is only carried out with minimal temperature. If a sufficiently large storage system is available, it is advisable to switch the hot water heating or reheating to overnight in order to use the low-tariff periods that are often cheaper. Thermal disinfection In the menu item "Hot water - Thermal disinfection", on bivalent systems or with domestic hot water cylinders with installed flange heater, thermal disinfection can take place with domestic hot water temperatures of up to 85 °C. The thermal disinfection can take place at a start time that can be set for each weekday. 452117.66.20-EN · 1/2021-07 · Rei 16-76 Operating manual Heat pump manager WPM 6.0 4 User level Circulation In the menu item "Hot water - Circulation", the actuation of the circulation pump can be programmed. A maximum of two time windows can be defined. A maximum of two circulation times can be assigned to each weekday. Exceeding demands are activated or deactivated at midnight. TIP A circulation line uses large amounts of energy. To save on energy costs, circulation should not be used. If this is unavoidable, it is advisable to adapt the time window to the optimal conditions. A better approach is to have the circulation running via an impulse for a specific time. This function is also possible with the heat pump manager.

The heating curve should be set to the calculated maximum return temperature of the heating system. Via the plus and minus keys, the heating curve can be moved up or down in parallel on a customer-specific basis to achieve the actual desired room temperatures. Regulation via the return temperature Regulating a heat pump heating system via the return temperature has the following advantages: 1) Long runtimes of the heat pump with demand-based heating of the entire circulated heating volume. 2) Recording of the disturbance variables of the heating system. 3) Reducing the temperature spread results in lower flow temperatures with a constant return temperature, thus achieving a more efficient operation. TIP The heating curve should be set as high as necessary and as low as possible! 7.1 Outside temperature-dependent heating curve The heating curve must be adapted to the local and structural conditions - separately for heating circuits 1, 2 and 3 - so that the desired room temperature is achieved even with changing outside temperatures. If the outside temperature rises, the return set temperature is lowered, thus ensuring energy-efficient operation of the heating system. 1) In the settings, the maximum required return temperature is entered at 20 °C outside temperature. The goal is to achieve an average, constant room temperature even with changing outside temperatures. 2) All heating characteristic curves meet at an outside temperature of +20 °C and a return temperature of +20 °C, so that heat output is no longer required in this operating point. The bar display (plus and minus keys) can be used to shift this operating point between 5 °C and 30 °C along the inclined marked axis. This shifts the entire heating curve in parallel upwards or downwards by a constant value of 1K per bar unit. The user can carry out this setting according to their individual desired temperature. 3) Each heating curve is limited by the maximum set value. Each heating curve has a lower limit of 18 °C (air-to-water HP) or 15 °C (brine or water-to-water HP). 60 Heating curve parallel shift (warmer) with 55 heating curve maximum 50°C 50 Heating curve e.g. radiators 45 40 35 Heating curve 30 e.g. underfloor 25 Heating curve parallel shift (colder) 20 15 Return set temperature in °C 10 5 0 -20 -15 -10 -5 Colder 5 Warmer 30 25 20 15 10 0 5 10 15 20 25 30 35 40 Outside temperature in °C 452117.66.20-EN · 1/2021-07 · Rei 50-76 Operating manual Heat pump manager WPM 6.0 7 Energy-efficient operation 7.1.1 Setting examples Standard outside air temperature °C Required flow temperature (with standard design temperature) Temperature spread flow/return Required return temperature (with standard design temperature) Setting for heating curve end point Underfloor heating 35 °C / 28 °C -12 -14 -16 Radiators 55 °C / 45 °C -12 -14 -16 35 °C 35 °C 35 °C 55 °C 55 °C 55 °C 7 °C 7 °C 7 °C 10 °C 10 °C 10 °C 28 °C 28 °C 28 °C 45 °C 45 °C 45 °C 30 °C 29 °C 29 °C 48 °C 47 °C 46 °C Example 1 Example 2 A heat distribution system (e.g. underfloor heating) is designed for a maximum flow temperature with a specific standard outside temperature. This is dependent on the location of the heat pump and is between -12 and -18 °C in Germany. The max. return temperature to be set on the heating controller must be entered with an outside temperature of 20 °C. For this, the maximum return temperature with the specified standard outside temperature in Abb. auf S. 51 must be entered. Via the array of curves, the setting value at -20 °C can be read.

Control behaviour The larger the deviation between the room and the room set temperature, the faster the return set temperature is adapted. Where necessary, the response time can be changed via the adjustable interval value (I-value). The larger the interval value, the slower the adjustment of the room set temperature. The minimum return set temperature adjusts automatically to the set room temperature. If this is not desired, there is the option of switching from "automatic" to "manual" in the menu "Heat circuit - Return temperature minimal". Requirements: For systems with silent cooling, the room climate station or reference room modulator RTH Econ/RTM Econ is used for room temperature recording. For all others, an additional room sensor (R13) must be connected on the analogue input X3/R13. Deactivation of an existing individual room control in the reference room The required return temperature is recommended as an input for a maximum return set temperature with standard design temperature. Even room set temperature, mostly free from increases and decreases When the room temperature control is activated or the room set temperature is changed, the room temperature may initially be overshot. 452117.66.20-EN · 1/2021-07 · Rei 52-76 Operating manual Heat pump manager WPM 6.0 8 Domestic hot water preparation 7.2.1 Setting examples Recommended settings for room set temperature 22 °C Surface heating (35/28 °C) (underfloor, wall, ceiling Low temperature radiators (45/38 °C) Radiators (55/45 °C) Minimum return temperature 22 °C 25 °C 30 °C Maximum return temperature 30 °C 40 °C 50 °C For optimal regulation, the regulation range between the minimum and maximum return temperature should be as small as possible. The automatic operating mode switching enables the heating operation to be blocked from a selectable outside temperature. 7.2.2 Optimisation of the room temperature control 1st measure Building too warm Reduce the room set temperature Building not getting warm Increase the room set temperature, Increase the volume flow Reference room warm, individual rooms (e.g. bathroom) too cold Hydraulic alignment (reduce volume flow in the reference room) Reference room not reaching the room set Hydraulic alignment (increase volume temperature, individual rooms (e.g. bathroom) flow in the reference room) are warm 2nd measure Increase the maximum return temperature Increase the maximum return temperature 7.3 Fixed value regulation For special cases (e.g. charging a buffer to constant temperature), an outside temperaturedependent characteristic curve can be set. When the room temperature control is activated or the room set temperature is changed, the room temperature may initially be overshot. 8 Domestic hot water preparation For domestic hot water preparation, domestic hot water cylinders with sufficiently large heat exchange surfaces must be used, that are able to transfer the maximum heat output of the heat pump permanently. The regulation takes place via a sensor (R3) installed in the domestic hot water cylinder, which is connected to the heat pump manager. The achievable temperatures in pure heat pump operation are below the maximum flow temperature of the heat pump. For higher domestic hot water temperatures, the heat pump manager offers the option of actuating a flange heater. Alternatively, regulation can take place via a thermostat. In this application, targeted reheating via a flange heater is not possible. 452117.66.20-EN · 1/2021-07 · Rei 53-76 Operating manual Heat pump manager WPM 6.0 8 Domestic hot water preparation 8.1 Basic heating A domestic hot water request is detected if the current domestic hot water temperature is < domestic hot water set temperature - domestic hot water hysteresis. A domestic hot water request is ended if the domestic hot water set temperature or the heat source-dependent determined heat pump maximum temperature is reached. The domestic hot water preparation can be interrupted by defrosting or by the high pressure protection program. Menu Preconfiguration Preconfiguration Submenu Domestic hot water preparation Flange heater Setting Yes with sensor No 8.1.1 Achievable domestic hot water temperatures The maximum domestic hot water temperature that can be achieved in pure heat pump operation depends on: The heat output of the heat pump The the heat exchanger surface installed in the cylinder The volume flow depending on the pressure drop and delivery rate of the circulating pump. 8.1.2 Heat source-dependent domestic hot water temperatures The heat pump manager automatically determines the maximum possible domestic hot water temperature, referred to as the heat pump maximum temperature. The heat pump maximum temperature is also dependent on the current temperature of the heat source air, brine or water. To ensure that the maximum possible domestic hot water temperature is always achieved, the permissible range of the heat source temperature is divided into temperature ranges. A specific heat pump maximum temperature is assigned to each range, each heat pump maximum temperature is set to 65 °C as the default value. If the high pressure switch is triggered during domestic hot water preparation with the heat pump, the current heat source temperature is recorded and the corresponding heat pump maximum temperature is determined as follows: 1 K is deducted from the current measured domestic hot water temperature and saved as the heat pump maximum temperature. 452117.66.20-EN · 1/2021-07 · Rei 54-76 Operating manual Heat pump manager WPM 6.0 8 Domestic hot water preparation Menu Preconfiguration Preconfiguration Settings 8.2 Reheating Reheating means that the heat pump takes over the domestic hot water preparation until the heat pump maximum temperature is reached. Another heat generator then takes over the domestic hot water preparation until the desired domestic hot water set temperature is reached. Reheating is only activated if the desired set temperature is higher than the current heat pump maximum temperature. Reheating is started if the domestic hot water temperature is higher than the maximum temperature that can be achieved with the heat pump. If the domestic hot water temperature falls below the domestic hot water set temperature hysteresis hot water during reheating, the reheating is stopped and basic heating is started via the heat pump. The selection of the relevant heat generator for the domestic hot water generation depends on the mode of operation of the heat pump heating system, the configurations and the current statuses of the system. The reheating must be released in the menu "Settings Hot water reheating". Submenu Domestic hot water preparation Flange heater Domestic hot water reheating Setting Yes with sensor Yes Yes 8.3 Thermal disinfection A start time is specified for thermal disinfection. When the thermal disinfection is started, the system immediately attempts to reach the set temperature. The selection of the heat generator used for this depends on the mode of operation of the heat pump heating system, the configurations and the current statuses of the system. Thermal disinfection is ended when the set temperature is reached. For the thermal disinfection setting menu to be released, a bivalent heating system and/or flange heater must be set with "Yes" in the preconfiguration. If the set temperature is not reached after 4 hours, the thermal disinfection is cancelled. The set start time can be activated or deactivated individually for each weekday. 8.4 Domestic hot water lower time A domestic hot water lower time can be set for two different times and weekdays. Despite a domestic hot water lower time, a minimum domestic hot water temperature can be defined for comfort purposes. The minimum domestic hot water temperature is always maintained during a domestic hot water block. A domestic hot water request takes place if the minimum domestic hot water temperature hysteresis is not reached. 452117.66.20-EN · 1/2021-07 · Rei 55-76 Operating manual Heat pump manager WPM 6.0 9 Program description 9 Program description 9.1 Limit temperature The outside temperature at which the heat pump just covers the heat consumption is known as limit temperature 2nd heat generator or bivalence point. This point is marked by the transition from pure heat pump operation to bivalent operation together with immersion heater or boiler. The theoretical bivalence point can deviate from the optimal point. Particularly in transition periods (cold nights/ warm days), a lower bivalence point can reduce the energy consumption according to the wishes and habits of the operator. Therefore, a limit temperature for releasing the 2nd heat generator can be set in the menu "2. heat generator Limit temperature". Usually, the limit temperature is only used with mono energy systems with air-to-water heat pumps or with bivalent systems in combination with boilers. In mono energy operation, a limit temperature of 5 °C is strived for. The limit temperature is determined from the outside temperature-dependent building heat consumption and the heat pump heat output curves. 9.2 Blocking requests Different statuses and settings can result in the heat pump request being blocked. The indicated blocks are reset automatically or are removed once they have been addressed. 9.2.1 Utility block The utility company (Energie-Versorgungs-Unternehmen - EVU) can make a temporary switch off of the heat pump a condition for low-cost electricity tariffs. During a utility block, the voltage on terminal X3/A1 is interrupted. For systems without utility block, the link cable provided must be inserted on the relevant terminal points. The utility block is set in the menu "2. heat generator EVU block". With bivalent systems, different responses to a utility block are possible: Load stage 3 only Heat pump blocked, the 2nd heat generator is only released in load stage 3. Permanent: The 2nd heat generator is always released in the event of a heat request during a utility block. Limit temperature dependent Heat pump blocked, the 2nd heat generator is released below the selectable limit temperature EVU3. For mono energy and monovalent systems, the 2nd heat generator is generally blocked during a utility block. The setting for the utility block is hidden. For an external heat pump operation block that does not reset automatically after max. 2 hours, the external disable contactor (contact X3/A2) must be used. If the minimum permissible return temperature is not met, the heat pump is also released when a blocking signal is present. 452117.66.20-EN · 1/2021-07 · Rei 56-76 Operating manual Heat pump manager WPM 6.0 9 Program description 9.2.2 Line load The line switch-on load is a requirement of the utility companies. It can last for up to 200 seconds after the voltage is restored or after utility block. The line load can not be bypassed. 9.2.3 Minimum pause time To ensure adequate pressure compensation in the refrigeration circuit and to protect the heat pump, it can take up to 5 minutes to switch on the compressor again. The heat pump starts after the minimum pause time has elapsed in order to fulfil a pending demand. The minimum pause time can not be bypassed. 9.2.4 Switch cycle block According to the connection conditions of the utility companies, the heat pump may only switch on 3 times per hour. The heat pump manager will therefore only allow a switch-on every 20 minutes as a maximum. 9.3 2nd heat generator 9.3.1 Control of immersion heaters In mono energy systems, electrical additional heating systems are used. They are switched on or off depending on the heat consumption requirements, if "mono energy" operating mode is selected in the preconfiguration menu and the set limit temperature is not met. 9.3.2 Control pipe heating An electrical pipe heating can be used in mono energy systems. The electrical pipe heating is selected in "Preconfiguration - Electric heating - Pipe heating Heating/DHW/SP" and switched on or off based on demand in heating, domestic hot water or swimming pool mode. 9.3.3 Constant control boiler With this type of boiler, the boiler water is constantly heated to a fixed set temperature (e.g. 70 °C) if a release from the heat pump manager is in place. The set temperature must be set high enough that the domestic hot water preparation can also take place via the boiler if necessary. The mixer is controlled by the heat pump manager, which issues a request to the boiler as necessary and adds enough hot boiler water to reach the desired return set temperature or domestic hot water temperature. The boiler is requested via the output 2nd heat generator of the heat pump manager and the operating mode of the 2nd heat generator must be coded to "constant". 452117.66.20-EN · 1/2021-07 · Rei 57-76 Operating manual Heat pump manager WPM 6.0 9 Program description 9.3.4 Sliding control boiler In contrast to a constant control boiler, the sliding control boiler delivers the heating water temperature to match the outside temperature directly. The 3-way reversing valve has no control function and is only responsible for guiding the heating water flow past the boiler circuit or through the boiler depending on the operating mode. In pure heat pump operation, the heating water is directed past the boiler to avoid losses due to the heat emission of the boiler. If a weather-compensated burner regulation is already in place, the power supply for the burner regulation must be interrupted during exclusive heat pump operation. For this, the control of the boiler must be connected to the output 2nd heat generator of the heat pump manager and the operating mode of the 2nd heat generator must be coded to "sliding". The characteristic curve of the burner regulation is set according to the heat pump manager. 9.3.5 Special program for older boilers and central storage systems If a request was issued to the second heat generator and the special program is activated in the menu "2. heat generator", the 2nd heat generator remains in operation for at least 30 hours. If the heat consumption reduces in this time, the second heat generator enters "standby mode" (2nd heat generator connected to voltage, but mixer CLOSED). It is only switched off completely if no request is issued for the 2nd heat generator or 30 hours. This function can be used for bivalent systems as follows: 1. With older oil or gas boilers to prevent corrosion damage due to frequent dropping below the dew point. 2. With central storage systems so that the storage charging is guaranteed for the following day irrespective of the current heat consumption. 9.3.6 Bivalent-parallel In "2. heat generator", the "Limit temperature parallel" is defined. If the limit temperature parallel is not met, a parallel request is sent to the heat pump and the 2nd heat generator if required. 9.3.7 Bivalent-alternative In the menu "2. heat generator", the "Limit temperature alternative" is defined. If the limit temperature alternative is not met, the heat pump is blocked and the 2nd heat generator is released for both heating and domestic hot water preparation. If alternative operation rather than parallel is always desired, the limit temperatures alternative and parallel must be given the same value. 9.3.8 Bivalent-renewable When integrating a renewable heat source (e.g. solar, wood), it must be given priority over heat pump operation. To this end, bivalent-renewable is coded in the preconfiguration. While the renewable storage is cold, the system behaves like a mono energy system. The sensor of the renewable storage is connected to analogue input N1-B8. The mixer outputs of the bivalence mixer are active. For heat pumps without an integrated flow sensor, one must be retrofitted (N1-B5). 452117.66.20-EN · 1/2021-07 · Rei 58-76 Operating manual Heat pump manager WPM 6.0 9 Program description Basic function: The temperature in the renewable storage is recorded and compared with the flow temperature of the relevant request (domestic hot water, heating or swimming pool). If the temperature is higher than the conditions listed below, the heat pump is blocked, the renewable storage is used as a 2nd heat generator and the bivalence mixer is controlled accordingly. Block by heating request: If the temperature in the storage is 2-20 K higher than the current flow temperature, the heat pump is blocked in the event of a heating request. It is only released again when the difference between the renewable storage and the flow is less than half of the switching value. For solar integrations, the selectable overtemperature must be set to the maximum value to prevent the heat pump from cycling. Block by domestic hot water request: If the temperature in the storage is 2-5 K higher than the current domestic hot water temperature, the heat pump is blocked in the event of a domestic hot water request. It is only released again when the difference between the renewable storage and the domestic hot water is less than half of the switching value. Block by swimming pool request: If the temperature in the storage is higher than 35 °C (value can be set in the menu - Settings - 2. heat generator overtemperature of 1050 °C), the pump is blocked in the event of a swimming pool request. It is only released when the temperature in the parallel buffer is 5K below the switching temperature again. As soon as one of the three blocks outlined above is in place, the heat pump is blocked and the display shows: HP waiting, block BR. The output 2nd heat generator is not actuated. Mixer control: If no bivalent-renewable block is in place, the mixer is controlled permanently CLOSED. If a bivalent-renewable block is in place due to domestic hot water or swimming pool, the mixer is controlled permanently OPEN. If a bivalent-renewable block due to heating is in place, the mixer regulation is active. 9.4 Power control The heat pump manager defines a maximum of 3 load stages, L1, L2 and L3, which it switches depending the heat consumption. If the heat consumption rises, it switches to the next highest load stage and if the heat consumption falls, it switches to the next lowest load stage. L1: Heat pump runs with one compressor L2: Heat pump runs with two compressors L3: Heat pump runs and 2nd heat generator is active (not with monovalent systems) After commissioning or after a power failure, the heat pump manager always starts in load stage L1. The load stages are not redefined during defrosting, swimming pool preparation, domestic hot water request, or during a utility block. 452117.66.20-EN · 1/2021-07 · Rei 59-76 Load stage Stage L1 Stage L2 Stage L3 Defrost Hot water heating Swimming pool heating Operating manual Heat pump manager WPM 6.0 9 Program description 9.4.1 Heat pumps with one compressor Criteria for switching: from L1 to L3, if the heat pump manager requests "more heat" for longer than 60 minutes and, at the same time, the outside temperature is below the limit temperature of the 2nd heat generator for longer than 60 minutes from L3 to L1, if the heating controller requests "less heat" for longer than 15 minutes or the limit temperature is exceeded. 9.4.2 Heat pumps with two compressors Criteria for switching: from L1 to L2, if the heat pump manager requests "more heat" for longer than 25 minutes, from L2 to L3, if the heat pump manager requests "more heat" for longer than 60 minutes and, at the same time, the outside temperature is below the limit temperature for longer than 60 minutes, from L3 to L2 or L1, if the heat pump manager requests "less heat" for longer than 15 minutes or the limit temperature is exceeded, from L2 to L1, if the heat pump manager requests "less heat" for longer than 15 minutes. In load stage L1, a compressor of the heat pump is switched on or off according to the "more" or "less" signals of the heat pump manager. In stage L2, a compressor of the heat pump runs constantly to cover the basic load. The second compressor is switched on or off in accordance with the "more" or "less" signals of the heat pump manager. In stage L3, both compressors run constantly to cover the increased basic load, the second heat generator is regulated. There is only ever one compressor running during defrosting. Heat pump with one compressor Heat pump with two compressors only one compressor cycling only one compressor cycling - 1 compressor basic load, 1 compressor cycling one compressor and second heat both compressors and second heat generator generator if necessary Compressor running One compressor running Compressor running One or two compressors are running depending on the outside temperature Compressor running One or two compressors are running depending on the outside temperature 9.4.3 High temperature air-to-water heat pumps With outside temperatures over 10 °C, there is generally only 1 compressor running. If the outside temperature is below 10 °C and the flow temperature is higher than 50 °C, both compressors are released: Compressor 1 is switched on first, followed shortly after by compressor 2. If the request disappears or a block becomes active, both compressors are switched off at the same time. With regard to the load stage, the high temperature heat pump behaves like a 1-compressor heat pump in this temperature range, regardless of the selection in the Configuration menu, i.e. there is no load stage 2. If the outlined conditions for switching to load stage 3 are fulfilled, the 2nd heat generator is released. 452117.66.20-EN · 1/2021-07 · Rei 60-76 CAUTION Operating manual Heat pump manager WPM 6.0 9 Program description 9.5 Hysteresis The so-called hysteresis can be set for different requirements in the menu. The hysteresis forms a "neutral zone" around the relevant set temperature. If the current temperature is lower than the set temperature reduced by the hysteresis, a request is detected. This remains in place until the current temperature has exceeded the upper limit of the neutral zone. This results in a switch cycle around the setpoint. Hysteresis return set temperature For the heating request, a hysteresis can be set around the return set temperature. If the hysteresis is large, the heat pump runs for longer and the temperature fluctuations in the return are correspondingly high. With a small hysteresis, the compressor run times are reduced and the temperature fluctuations are lower. For surface heating systems with relatively flat characteristic curves, a hysteresis of approx. 1 K must be set, as an excessively large hysteresis can prevent the heat pump from switching on. 9.6 Control of the circulating pumps The control of the heating, domestic hot water or swimming pool circulating pump determines where the heat generated by the heat pump should flow. The separate processing of different requests enables the heat pump to always work with the minimum possible flow temperature, thus ensuring energy-efficient operation. With heat pumps for heating and cooling, additional cooling circulating pumps can be controlled. Pump assemblies with check valves guarantee defined flow directions. In the summer operating mode, the heating pump runs for 1 minute every 150 hours (this prevents the heating pump from jamming at the start of the heating period). 9.6.1 Frost protection Irrespective of the heat circulating pump settings, they always run in heating, defrost mode and when there is a risk of frost. For systems with multiple heating circuits, the 2nd/3rd heat circulating pump has the same function. In order to guarantee the frost protection function of the heat pump, the heat pump manager must not be deenergised and the heat pump must have flow through. 452117.66.20-EN · 1/2021-07 · Rei 61-76 Operating manual Heat pump manager WPM 6.0 9 Program description 9.6.2 Heat circulating pump For the heat circulating pump (M13, M15, M20), an outside temperature-dependent heating pump optimisation is set in the menu "Pump control - Optimisation heating pump". If the selected limit temperature is not reached, the heating pump optimisation is inactive. The heat circulating pumps are permanently in operation, except during domestic hot water, swimming pool preparation and in "Summer", operating mode. If the selected limit temperature is exceeded, the heating pump optimisation is active. The heat circulating pumps run after a mains switch-on and for 30 minutes after the heat pump is switched off. If the heat circulating pumps had been switched off for longer than 40 minutes or if the return set temperature has intentionally been increased via a raise, the heat circulating pumps are activated for a 7 minute scavenging time to supply the representative temperature of the heating circuits to the return sensor (R2, R2.1) again. If a switch takes place from heating to domestic hot water or swimming pool preparation, the heat circulating pump carries out an after-run. The heat circulating pumps are permanently in operation if the minimum system temperatures are not met and with temperatures below 10 °C on the frost protection sensor (R9) of the air-to-water heat pumps. In Summer operating mode, the circulating pump runs for 1 minute every 150 hours. This prevents the shaft from jamming. 9.6.3 Domestic hot water circulating pump The domestic hot water circulating pump (M18) runs during domestic hot water preparation. If a domestic hot water request is issued during heating operation, the heat circulating pump is deactivated while the heat pump is running and the domestic hot water circulating pump is activated. 9.6.4 Swimming pool circulating pump The swimming pool circulating pump (M19) runs during swimming pool preparation. A running swimming pool preparation is interrupted at any time by a domestic hot water request, defrosting process or by an increase in the heating characteristic curve (e.g. after night lowering), but not by a heat pump manager "more" signal. If the request is still in place after a 60-minute swimming pool preparation, the swimming pool circulating pump is deactivated for 7 minutes and the heat circulating pump is activated for a 7-minute scavenging time to supply the representative temperature of the heating circuit to the return sensor again. If the heat pump manager generates a "more" signal during these 7 minutes, the heating request is processed first. In Summer operating mode, the swimming pool preparation is not interrupted by a scavenging time after 60 minutes. 452117.66.20-EN · 1/2021-07 · Rei 62-76 Operating manual Heat pump manager WPM 6.0 9 Program description 9.6.5 Auxiliary circulating pump The auxiliary circulating pump output (M16) can be configured to achieve parallel operation of the auxiliary circulating pump with the compressor of the heat pump. A configuration for heating, domestic hot water and swimming pool preparation is possible. It also runs if the minimum system temperatures are not met. In Summer operating mode, the circulating pump runs for 1 minute every 150 hours. This prevents the shaft from jamming. 9.6.6 Primary pump for heat source The primary pump (M11) supplies the energy of the heat source to the heat pump Heat pump type Air-to-water heat pump Brine-to-water heat pump Water-to-water heat pump Primary pump Fan Brine circulating pump Well pump The well water pump or brine circulating pump always runs if the heat pump is switched on. It starts up 1 minute before the compressor and switches off 1 minute after the compressor. For air-to-water heat pumps, the fan is switched off during defrosting. 9.6.7 Circulation pump If there is the option of connecting a circulation pump (M24), it can be requested via an impulse input or via time programs. If the circulation pump is requested via the impulse input (X3/G - ID17), the delay time can be defined in the menu "Hot water circulation". If the request takes place via a time program, it can be set for two different times and weekdays. TIP A circulation line uses large amounts of energy. To save on energy costs, circulation should not be used. If this is unavoidable, it is advisable to adapt the time window to the optimal conditions. A better approach is to have the circulation running via an impulse for a specific time. This function is also possible with the heat pump manager. 452117.66.20-EN · 1/2021-07 · Rei 63-76 CAUTION Operating manual Heat pump manager WPM 6.0 9 Program description 9.7 Building management system From software version L09, there are two options for connecting the heat pump to a building management system. Transferring the set values on an interface via the BMS (Building Management System). Different protocols and interfaces are available for this. Wiring digital inputs with the option of influencing the described power control on the heat pump manager. There is also the option of switching the operating mode via digital inputs both from heating to cooling and influencing it via a parametrizable external block (frost protection/domestic hot water/holiday/summer). In all cases, the primary pump (M11) and the secondary pump (M16), or the heat circulating pump (M13) depending on the hydraulic integration, must be connected to the heat pump manager. This is the only way to ensure that the pump flow and afteruns required for operation are observed and the necessary safety measures are effective. 9.7.1 BMS interface On the BMS interface, the extensions available as special accessories for connection to: LAN KNX Modbus are provided. Via these extensions, the operating data and history can be read out and settings such as Modus or setpoint specifications can be made, among other things. In general, a request from the heat pump in conjunction with the building management system should be favoured over an interface. If an interface such as this is used, the following programming is suggested on the heat pump manager. Depending on the number of heating or cooling circuits, they are set to a fixed value regulation. The set temperature calculated by the building management system is transferred to the heat pump manager as the fixed value temperature. The heat pump is also switched to the Auto, Summer and Cooling mode via the building management system. Further information on these options can be found in the description for the relevant product. 9.7.2 Compressor control via digital inputs In addition to the setpoint specification via the building management system, the compressor can also be controlled via digital inputs. 452117.66.20-EN · 1/2021-07 · Rei 64-76 Load stage Stage L1 Stage L2 Stage L3 Operating manual Heat pump manager WPM 6.0 9 Program description Load stages The load stages (L) are influenced via the digital inputs N1-J5/ID1 and N1-J5/ID2. An overview of the load stage switching is shown in the table. Load stage Stage L1 Stage L2 Stage L3 N1-J5/ID1-X3/G closed open closed N1-J5/ID2-H§/G open closed closed The load stage switching takes place as described in load stage controls. It must be noted here that the building management system can increase and reduce the load stages within the operating limits. The TAB of the utility companies are still in effect here. The set temperatures set on the heat pump manager are ignored. In extreme cases, the heat pump is only blocked via the operating limits (high and low pressure, flow and return temperature) or switched off by the safety functions. The table shows the load stage switchings and their impact on the compressors and 2nd heat generator or refrigerator. Switching the load stages With parallel connections of heat pumps, it is advisable to set up and program the load stages as a ring connection. This means that, depending on the required output, heat pump 1 is released with L1, then heat pump 2 with L1 and heat pump 3 with L1. If additional power is required, heat pump 1 is released with L2, followed by heat pump 2 with L2 and heat pump 3 with L3. Switching back takes place in the same way. Firstly, heat pump 1 is switched in L1, heat pump 2 in L1 and then heat pump 3 in L1. This means that the compressors not only receive the same runtimes, but the heat pumps are also operated in the most efficient way with this measure.

If the functions "Load stage switching" and "External block" are to be used, these functions must be activated by after-sales service during the commissioning of the heat pump. 9.7.4 Switching heating/cooling With heat pumps for heating and cooling, the switching of the operating mode takes place via a digital input on the expansion mode N17.1-J4/ID4-X3/G. Operating mode Heating Cooling N17.1-J4/ID4-X3/G open closed 10 Commissioning of air-to-water heat pumps To guarantee the defrosting with air-to-water heat pumps, the return temperature must be at least 18 °C to prevent the defrosting from being cancelled due to the value falling below the minimum permissible temperature on the frost protection sensor. Activating the commissioning function (special function) releases the 2nd heat generator for one hour, suppresses a defrosting process or cancels a defrosting process currently in progress. The heat circulating pump runs permanently during commissioning and a domestic hot water or swimming pool request is ignored. With low heating water temperatures, the buffer tank must be heated up first before the individual heating circuits are opened one after the other. 452117.66.20-EN · 1/2021-07 · Rei 66-76 Operating manual Heat pump manager WPM 6.0 11 Initial heating program (screed drying) 11 Initial heating program (screed drying) The initial heating of a screed takes place in accordance with defined standards and directives, which have, however, been adapted to the requirements of a heat pump heating system. The individual programs are activated in the menu "Special functions - Screed drying"). The following applies during initial heating: The heat circulating pumps for heating circuits 1, 2 and 3 run permanently Programmed lowers or increases are ignored, a fixed hysteresis of ± 0.5 K applies (regardless of the configuration in the menu) Limit temperature for the 2nd heat generator fixed at +35 °C (regardless of the configuration in the menu) The calculated set temperature applies for all heating circuits The mixer of heating circuit 2/3 is controlled with permanently open In the event of a fault or an interruption in voltage, the selected program is only interrupted. Once the voltage is restored or the fault is acknowledged, the selected program is continued. If there are no special requirements from the manufacturer, the use of the standard program line heating is recommended (max. return temperature 35-40 °C). If no key is pressed 3 minutes after an initial heating program is activated, the display switches every minute. The current heat up step, set temperature, elapsed hours and required hours are shown in the bottom display line. 11.1 Implementation of the directive for a heat pump heating system The directive is based on whole days for which a defined temperature is to be reached or maintained. With high humidity levels in the screed, the defined temperatures are often not reached in the specified time. For sufficient drying, however, it is essential that the temperature level is maintained for a specific period of time. For this reason, the days described in the standard are converted to program steps, where one program step corresponds to the combination of the number of days or hours and the relevant temperature. Depending on the ratio of heat output from the heat pump and heated living area, the specified minimum heat up times can also be significantly exceeded, as the required minimum number of hours is only totalled up after the set temperature is reached. The relevant standards and directives describe the flow temperature of the heating system in each case. The return temperature is key for controlling the heat pump. The maximum return temperature must be entered for the initial heating program. This is calculated from the maximum flow temperature, minus the temperature spread (e.g. 7 K). 452117.66.20-EN · 1/2021-07 · Rei 67-76 Operating manual Heat pump manager WPM 6.0 11 Initial heating program (screed drying) 11.2 Heating function program in accordance with DIN EN 1264-4 This program serves as a function test for underfloor heating and is only carried out after the specified rest time of the screed. This is designed to highlight any faults in the screed and in the underfloor heating. 1). Step: A constant return temperature of 20 °C must be maintained for 72 hours (3 days). 2). Step: The maximum return temperature (selectable) must be maintained for 96 hours (4 days). 3). Step: The heat pump remains off until the return temperature has dropped below 20 °C. The duration of step 3 is limited to a maximum of 72 hours, as, in high outside temperatures, the return temperature may not fall below 20 °C. The heating function program should be carried out to check the function of the underfloor heating system. With cement screed, this may take place after 21 days at the earliest, with calcium sulphate screed, after 7 days at the earliest after the screed work is complete. Once the screed has been created, after the required rest time and after the heating function program, the readiness for further processing must be confirmed before applying the upper floor covering. 11.3 Line heating to dry out the screed 11.3.1 General notes This program reduces the humidity in the screed to a level where the floor covering can be applied. The moisture content must be measured, however, and additional drying carried out where necessary. The guidelines for drying the screed specify a fixed number of steps with defined temperatures and durations. This sequence can be selected in the menu as "Standard program line heating". The standard program should be used in most cases in agreement with the screed installer. The sequence defined for the standard program should only be individually adapted if there are special requirements for the heating. In this case, select "Individual program line heating" in the menu. 452117.66.20-EN · 1/2021-07 · Rei 68-76 Operating manual Heat pump manager WPM 6.0 11 Initial heating program (screed drying) 11.3.2 Standard program line heating This program consists of 8 steps and is usually suitable for all underfloor heating systems. Before activation, the maximum permissible return temperature must be entered (e.g. 32 °C). Step 1-4: Step 5: Step 6-8: Heat up processes Hold Cool down processes Steps 1 to 4 are heat up processes lasting 24 hours each. With each step, the return set temperature is increased from 20 °C to the maximum return temperature. To end a program step, two conditions must be met. The corresponding set temperature must have been reached or exceeded and the duration of 24 hours must have elapsed. If the temperature is reached before the 24 hours have elapsed, the heat pump maintains the relevant set temperature for the remaining duration. No evaluation takes place of how long this temperature was actually reached for. In step 5, the maximum return temperature should be maintained for a period of 264 hours. The duration for which the maximum return temperature was actually reached is totalled up. Upper limit open, lower limit setpoint - hysteresis. Only when the totalled time has reached the value of 264 hours is this program step ended. Steps 6 to 8 are cool down steps lasting 24 hours each. The return set temperature is lowered with each step from the maximum return temperature to 20 °C. To end a program step, two conditions must be met. The value must be lower than the corresponding set temperature and the duration of 24 hours must have elapsed. If the value drops below the temperature before the 24 hours have elapsed, the heat pump maintains the corresponding set temperature for the remaining duration. No evaluation takes place of how long this temperature was actually reached for, however. The duration of the cool down processes is limited to a maximum of 72 hours, as, in high outside temperatures, the value may not drop below the required return temperature. Example: Max. return temperature: 32 °C Step 1-4: Step 5: Step 6-8: 20 / 24 / 28 / 32 °C Hold 28 / 24 / 20 °C 452117.66.20-EN · 1/2021-07 · Rei 69-76 Operating manual Heat pump manager WPM 6.0 11 Initial heating program (screed drying) 11.3.3 Individual program line heating This program enables the following settings to be made: Differential temperature heat-up: Starting from the initial temperature 20 °C through to the set maximum temperature, the set temperature is increased by the set difference with each program step. The number of steps is therefore based on these factors. Heat-up duration: The number of hours in which the relevant set temperature must be reached and maintained (function as described above) can be entered here. Hold duration: The number of hours for which the maximum set temperature must be maintained can be entered here. Differential temperature Cool down: Starting from the set maximum temperature through to the initial temperature 20 °C, the set temperature is reduced by the set difference with each program step. The number of steps is therefore based on these factors. Duration Cool down: The number of hours in which the relevant set temperature must be reached and should be maintained can be entered here. 452117.66.20-EN · 1/2021-07 · Rei 70-76 Operating manual Heat pump manager WPM 6.0 12 Extended installation instructions for the heat pump manager heating/cooling 12 Extended installation instructions for the heat pump manager heating/ cooling 12.1 Active cooling 12.1.1 Heat pumps without additional heat exchanger The cold generation takes place actively via heat pump process reversal. The switching of the refrigeration circuit from heating to cooling operation takes place via an internal four-way reversing valve. When switching from heating to cooling operation, the heat pump is blocked for 10 minutes so that the different pressures of the refrigeration circuit can balance out. The requests are processed as follows: Domestic hot water before Cooling before Pool During domestic hot water or swimming pool preparation, the heat pump works as in heating operation. 12.1.2 Additional heat exchanger for waste heat recovery Via an additional heat exchanger in the hot gas, the waste heat generated during cooling can be used for domestic hot water or swimming pool preparation. This requires "Yes" to be set in the Heat exchanger menu item. The requests are processed as follows: Cooling before Domestic hot water before Pool In the "Hot water" menu item, the hot water maximum temperature is set. While the domestic hot water temperature is below this limit, the domestic hot water circulating pump also runs during cooling. After the set maximum temperature is reached, the domestic hot water circulating pump is switched off and the swimming pool circulating pump is switched on (regardless of the swimming pool thermostat input). If no cooling requirement is in place, domestic hot water or swimming pool requests can be processed. However, these functions are cancelled after a maximum of 60 minutes uninterrupted runtime to give priority to processing an active cooling requirement. 452117.66.20-EN · 1/2021-07 · Rei 71-76 Operating manual Heat pump manager WPM 6.0 12 Extended installation instructions for the heat pump manager heating/cooling 12.2 Passive cooling Deep down, groundwater and the ground are significantly colder than the ambient temperature in summer. A plate heat exchanger installed in the groundwater or brine circuit transfers the refrigeration capacity to the heating/cooling circuit. The compressor of the heat pump is not active and is therefore available for domestic hot water preparation. The parallel operation of cooling and domestic hot water preparation can be activated in the menu item "Hot water- Parallel cooling hot water". For parallel operation of cooling and domestic hot water preparation, special requirements for the hydraulic integration must be guaranteed (see planning documents). 12.3 Program description cooling 12.3.1 Cooling operating mode The functions for cooling are activated manually as a 6th operating mode. An outside temperature-dependent switching of the "cooling" operating mode is also possible. External switching via the input N17.1-J4-ID4 is possible. The "Cooling" operating mode can only be activated if the cooling function (active or passive) is released in the preconfiguration. Switching off the cold generation The following limits are in place for protection: The flow temperature is below a value of 7 °C Triggering of the dew point monitor in sensitive parts of the cooling system Reaching the dew point with purely silent cooling 12.3.2 Activating the cooling functions When cooling operation is activated, special control functions are carried out. These cooling functions are carried out by the cooling controller separately from the other control functions. The following can prevent the activation of the cooling function: The outside temperature is below 3 °C (risk of frost) The outside temperature is below the cooling operating limit with reversible air-to-water heat pumps. The cooling controller is not in place or the connection is faulty (I/O extension). Neither silent nor dynamic cooling was selected in the heating/cooling circuit settings In these cases, the Cooling operating mode remains active, but the control behaves as in the Summer operating mode. 452117.66.20-EN · 1/2021-07 · Rei 72-76 Operating manual Heat pump manager WPM 6.0 12 Extended installation instructions for the heat pump manager heating/cooling 12.3.3 Circulating pumps in cooling operation With a heat pump heating system, which circulating pumps are activated or deactivated in which operating mode is defined in the preconfiguration of the relevant heating circuits. The heat circulating pump of heating circuit 1 (M14) is not active in cooling operation if pure silent cooling is configured. The heat circulating pump of heating/cooling circuit 2 (M15) is not active if only "heating" is selected. The heat circulating pump of heating/cooling circuit 3 (M20) is not active if only "heating" is selected. Heating components can be switched in heating or cooling operation via the floating contact N17.2 / N04 / C4 / NC4 (e.g. room temperature controller) Passive cooling The supply for the cooling system can take place via the existing heat circulating pump (M13) and via an additional cooling circulating pump (M17). The cooling circulating pump (M17) runs permanently in "Cooling" operating mode. Depending on the hydraulic integration with passive cooling, the running behaviour of the heat circulating pump (M13) can be changed under "Settings - Pump control". 12.3.4 Silent and dynamic cooling Different system configurations can be achieved depending on the integration diagram. The selection takes place in the menu "Settings Cooling". Pure dynamic cooling (e.g. fan convectors) The control corresponds to a fixed value regulation. The relevant desired return set temperature is set in the menu item Settings. Pure silent cooling (e.g. underfloor, wall surface or ceiling cooling) The control takes place based on the room temperature. The key factor is the temperature of the room where the room climate station 1 is connected according to the connection diagram. The relevant desired room temperature is set in the menu item Settings. The maximum transferable cooling capacity is heavily dependent on the relative humidity during silent cooling. A high humidity reduces the maximum cooling capacity, as the flow temperature is not reduced further once the calculated dew point is reached. Combination of dynamic and silent cooling The control takes place separately in two control circuits. The control of the dynamic circuit corresponds to a fixed value regulation (as described under dynamic cooling). The control for silent cooling takes place based on the room temperature (as described under silent cooling) by activating the mixer of heating circuit 2/3 (silent heating/cooling circuit). If the refrigerator switches off because the minimum flow temperature of 7 °C is reached, either the water flow must be increased or a higher return set temperature (e.g. 16 °C) must be set. 452117.66.20-EN · 1/2021-07 · Rei 73-76 Operating manual Heat pump manager WPM 6.0 12 Extended installation instructions for the heat pump manager heating/cooling 12.4 Room temperature control Heating technology systems are usually equipped with automatic mechanisms for controlling the room temperature on a room-by-room basis. In heating operation, the room thermostats record the current temperature and open the controller (e.g. actuator) if the value is below the specified set temperature. In cooling operation, the room thermostats must either be deactivated or replaced by ones suitable for heating and cooling. In this case the room thermostat behaves in the opposite way in cooling operation, meaning that the controller opens when the set temperature is exceeded. 452117.66.20-EN · 1/2021-07 · Rei 74-76 Operating manual Heat pump manager WPM 6.0 12 Extended installation instructions for the heat pump manager heating/cooling 452117.66.20-EN · 1/2021-07 · Rei 75-76 Max Weishaupt GmbH · 88475 Schwendi Weishaupt close by?
