Special information

SPECIAL INFORMATION

- The appliance may be used by children aged8 and up and persons with reduced physical, sensory or mental capabilities or a lack of experience and know-how, provided that they are supervised or they have been instructed on how to use the appliance safely and have understood the resulting risks. Children must never play with the appliance. Children must never clean the appliance or perform user maintenance unless they are supervised.

- Use a permanent connection to the power supply. Ensure the appliance can be separated from the power supply by an isolator that disconnects all poles with at least 3mm contact separation.

- Maintain the minimum clearances to ensure trouble-free operation of the appliance and facilitate maintenance work.

- There is no need to shut the system down in summer. The heat pump manager has an automatic summer/winter changeover.

DHW cylinders

- Regularly activate the safety valve to prevent it from becoming blocked e.g. by limescale deposits.

- Drain the DHW cylinder as described in the chapter "Installation/ Maintenance/ Draining the DHW cylinder".

- Install a type-tested safety valve in the cold water supply line. For this bear in mind that, depending on the static pressure, you may also need a pressure reducing valve.

- The safety valve discharge aperture must remain open to the atmosphere.

- Install the safety valve discharge pipe with a constant fall to the discharge outlet.

- In dual mode operation, return water from the second heat generator may ﬂow through the heat pump. Please note that the return water temperature may be a maximum of 60°C.

- Cooling mode is only possible in conjunction with the WPAC 1 cooling module. Set parameter COOLING to ACTIVE COOLING. The COOLING parameter will only be shown if a FEK or FE 7 remote control is connected. Cooling mode is only possible in summer mode.

- The air outlet in the knurled cap of the quick-action air vent valve must not point towards the MFG PCB. Close the quick-action air vent valve again after venting.

- Maintenance work, such as checking the electrical safety, must only be carried out by a qualiﬁed contractor.

- We recommend an annual inspection (to establish the system's current condition), and maintenance by a qualiﬁed contractor if required (to return the system to the desired condition).

- Size the discharge outlet so that water can drain off unimpeded when the safety valve is fully opened.

- Never interrupt the power supply, even outside the heating period. The system's active frost protection is not guaranteed if the power supply is interrupted.

Appliance description

WARNING Injury

!

The appliance may be used by children aged 8 and up and persons with reduced physical, sensory or mental capabilities or a lack of experience and know-how, provided that they are supervised or they have been instructed on how to use the appliance safely and have understood the resulting risks. Children must never play with the appliance. Children must never clean the appliance or perform user maintenance unless they are supervised.

Note

Do not change any system-speciﬁc settings at the control unit. Your contractor has set the control unit to match the local conditions for your building and your individual requirements. The system-speciﬁc parameters are protected by a code to prevent unintentional modiﬁcations. The parameters that serve to adapt the appliance to your personal requirements are not protected by a code.

CE designation

The CE designation shows that the appliance meets all essential requirements according to the:

- Electromagnetic Compatibility Directive

- Low Voltage Directive

bled. If the DHW learning function is enabled, DHW heating will cease and the set DHW value is overwritten with the actual DHW temperature achieved.

The WPM3i also controls the integral electric emergency/booster heater. No further heat generator can be switched.

3.1 Special features of the WPC...cool

An additional heat exchanger and 3-way diverter valve for changing over between heating and cooling are integrated into the WPC...cool.

To cool the living space, the brine is pumped though the additional heat exchanger, where heat is extracted from the heating water to be released into the cooler zones underground.

The compressor does not run during cooling.

2.4 Test symbols

See type plate on the appliance.

3. Appliance description

The appliance is a heating heat pump suitable for operation as a brine/water heat pump. The heat pump extracts energy from the heat source medium at a low temperature level. This extracted energy is then transferred to the heating water at a higher level, augmented by the electric energy drawn by the compressor. The heating water is heated to a ﬂow temperature of up to 60 °C, depending on the heat source temperature.

A heating circuit pump and a multi function assembly (MFG) with safety assembly and 3-way diverter valve have been integrated in the appliance for directing the ﬂow either to the heating circuit or the DHW circuit. To heat the DHW, the heating water that has been heated by the heat pump is directed through an indirect coil in the DHW cylinder, where it transfers its energy to the DHW.

The appliance is equipped with an electric emergency/booster heater (DHC). If the dual mode point can no longer be maintained in mono mode operation, the electric emergency/booster heater is activated to safeguard heating operation and the provision of high DHW temperatures. In mono energetic operation the electric emergency/booster heater is then activated as a booster heater.

The appliance is regulated by an integral, weather-compensated return temperature controller (WPM3i heat pump manager).

The WPM3i also regulates the DHW heating to the required temperature. If either the high pressure sensor or the hot gas limiter of the heat pump responds during DHW heating, then DHW heating will automatically be completed by an integral electric emergency/ booster heater, subject to the DHW learning function being disa-

You can now set three switching time pairs. The three switching time pairs are shown on the display, to the right of the clock. A switching time pair comprises the start time and end point, at which the appliance returns to its previous state.

Periods around midnight

Assume, for example, you want heating mode to be enabled from 22:00 h for four hours every Wednesday evening. This means the period does not expire until the next day, Thursday, at 02:00 h. Since the day ends at 00:00, two switching time pairs are necessary for the required program. First, program the period 22:00 to 00:00 h for Wednesday, then 00:00 to 02:00 h for Thursday.

5.3.2 DHW PROGRAM

26�04�01�0301

In the menu item DHW PROGRAM you can determine the times during which DHW heating with the set comfort value should take place. At all other times, DHW is heated to the set ECO value. You can select the set values under menu item SETTINGS/DHW/DHW TEMPERATURES.

You can set your DHW heating as follows:

- For each individual day of the week (Monday - Sunday)

- Monday to Friday (Mon - Fri)

- Saturday and Sunday (Sat - Sun)

- The whole week (Mon - Sun)

You can set three switching time pairs for each of these options.

Exception: If you want to heat DHW from 22:00 h until 06:00 h the following day you will need two switching time pairs.

Example:

OPERATION

Menu structure

You would like to heat DHW twice daily, from 22:00 h until 06:00 h the following day, and then from 08:00 h until 09:00 h.

As the day begins at 00:00 h, programming for this example must again start at 00:00 h.

- The ﬁrst switching time pair runs from 00:00 h until 06:00 h.

- The second switching time pair runs from 08:00 h until 09:00 h.

- The third switching time pair runs from 22:00 h until 24:00 h.

5.3.3 PARTY PROGRAM

In the party program you can extend the comfort mode for heating by a few hours.

5.3.4 HOLIDAY PROGRAM

In the holiday program, the heat pump system runs in ECO mode and frost protection for DHW heating is enabled.

For both the start and end of the holiday, enter the year, month and day. The start time is 0:00 h on the ﬁrst day of the holiday. The end time is 24:00 h on the day the holiday ends. After the holiday period has expired, the heat pump system switches back to the previous heating and DHW program.

Please note that only the mixer circuit pump is running when operating with 2 heating circuits.

If only direct heating circuit 1 is operational, the return sensor is again used for control. As the actual temperature inside the buffer cylinder is higher at the heating ﬂow, this conﬁguration results in 5 K being deducted from the set heat-up program values (low end and maximum temperatures).

Heat-up program for underﬂoor heating systems

Never use the heat pump for drying screed, as this places an excessive demand on the heat source and may cause it to be damaged. Use the electric emergency/booster heater for the heat-up program. For this, set LOWERAPPLIMITHEATING and DUALMODETEMPHEATING parameters to 30°C and start the heat-up program.

Emergency mode cannot be enabled in the heat-up program.

There are a total of 6 parameters for the heat-up program. These 6 parameters can be adjusted in sequence as soon as the heat-up program is activated. The program is started with the HEAT-UP PROGRAM parameter and with the setting ON. The system then heats to the selected low end temperature. The low end temperature is held for the set period (parameter TEMPRISEPERIOD). After expiry of this period, the system heats to the maximum low end temperature (parameter MAXIMUMTEMPERATURE) using an increase K/day (parameter RISEPER DAY) and holds this maximum temperature for the selected time (parameter MAXTEMPERATURE DURATION). The system subsequently returns to the low end temperature using the same steps as for heat-up. This concludes the heat-up program. As soon as 2 heating circuits are operational, both will be operated in line with the heat-up program (operation with buffer cylinder and mixer circuit). Direct heating circuit1 (buffer circuit with return sensor) adopts the set values of the heat-up program. Since this is regulated via the return sensor, the actual temperature inside the buffer cylinder is higher at the heating ﬂow. The mixer (heating circuit 2) regulates the temperature back down to the set values selected in the heatup program (low end temperature and maximum temperature).

The summer logic is disabled whilst the heat-up program runs.

Changing the set room temperature results in a parallel shift of the heating curve.

As soon as the FE7 remote control has been connected and allocated to heating circuit 1, the actual room temperature can also be scanned.

As soon as the FE7 or FEK remote control has been connected and allocated to heating circuit2, the actual room temperature can also be scanned.

The display HEAT CIRCUIT2 only appears if the mixer ﬂow sensor for heating circuit2 has been connected.

HEATING CURVE RISE

The menu item HEATING CURVE RISE enables you to set one heating curve each for heating circuits1 and 2.

Note: Your contractor will have set a building and system-speciﬁc optimum heating curve for every heating circuit. For heating circuit 1 the curve relates to the heat pump return temperature, for heating circuit 2 to the mixer ﬂow temperature.

When you adjust the heating curve on the heat pump manager, the calculated set return or ﬂow temperature, subject to the outside temperature and the set room temperature, will be shown at the top of the display.

As soon as you have preselected a temperature in menu SETTINGS / HEATING / STANDARD SETTING under parameter FIXED VALUE OPERATION, heating curve 1 is hidden from view and the display showsSETFIXED TEMPERATURE with the relevant temperature.

With heating systems, the temperature in a building during the transitional periods (spring and autumn) is too low when outside temperatures are between 5 °C and 15°C, despite open radiator valves, but is OK at outside temperatures ≤ 0°C. This problem can be remedied with a parallel shift and a simultaneous reduction of the heating curve.

STANDARD SETTING

BUFFER OPERAT

When using a buffer cylinder, set this parameter to ON.

SUMMER MODE

Parameter SUMMER MODE enables you to deﬁne the point at which the heating system is to switch to summer mode. Summer mode can be switched on or off. There are 2 adjustable parameters for this function.

- Parameter OUTSIDE TEMPERATURE:

Outside temperature adjustable from 10 °C to 30 °C

26�03�01�1915

- Parameter BUILDING HEAT BUFFER

This parameter lets you choose whether an average outside temperature should be determined, according to the type of building.

You can choose from 3 settings.

Setting "1": Minor insulation towards outside temperatures (averaging over a 24 h period), e.g.for timber construction with rapid heat transfer.

Setting "2": Moderate insulation towards outside temperatures (averaging over a 48 h period), e.g. brick construction with thermal insulation and average heat transfer.

Setting "3": Strong insulation towards outside temperatures (averaging over a 72 h period). House with slow heat transfer.

If the determined outside temperature is ≥ than the selected outside temperature, both heating circuits (if installed) enter summer mode; reverse hysteresis –1 K.

With ﬁxed-value control, summer mode is disabled for heating circuit 1.

MAXIMUM RETURN TEMP

Setting range 20 °C to 55 °C.

If the temperature at the return sensor reaches this set value dur-

26�03�01�1916+

ing heating operation, the heat pump is immediately switched off. This safety function prevents the high pressure switch from responding. No fault message is issued when this value is reached.

During DHW operation the return temperature is not scanned.

MAXIMUM FLOW TEMP

Maximum heat pump ﬂow temperature for central heating

Setting range 20 °C to 65°C.

This setting limits the ﬂow temperature of the heat pump and the electric emergency/booster heater in heating mode.

MIXER DYNAMICS

Mixer runtime

Setting range 60 to 240

You can use this setting to adapt the mixer characteristics. The setting 60 to 240 means 6 K to 24 K control deviation.

16 | WPC | WPC cool www.stiebel-eltron.com

OPERATION

Menu structure

The scan rate is 10 s and the minimum on time for the mixer is

0.5 s. The mixer does not respond in the dead zone of ±1 K from the set value.

Example for the setting 100 = 10 K

The control deviation (set mixer temperature – actual mixer temperature) is 5K. The mixer opens for 5 s, then pauses for 5 s and starts again.

The control deviation (set mixer temperature – actual mixer temperature) is 7.5 K. The mixer opens for 7.5 s, then pauses for 2.5 s and starts again.

The smaller the control deviation, the shorter the mixer on time and the longer the pauses.

A reduction of the MIXER DYNAMIC value with the control deviation unchanged increases the on duration and reduces pauses.

Example for setting 100 and a current control deviation of 5 K.

5 K of 10 K = 50% = on duration

Example: Control deviation

± 1 K

HEATING CIRCUIT OPTIMAL

When an Uponor DEM-WP module is connected, the heating curve is dynamically optimised for the heat demand of individual rooms. This involves modifying the preset heating curve by up to 50% of its original value.

The parameter HEATINGCIRCUITOPTIMAL is only displayed when the buffer operation parameter is set to "OFF" and neither a mixer sensor nor an FE7 remote control are connected.

The parameter HEATINGCIRCUITOPTIMAL can be set to "ON" or "OFF". The default value is "OFF".

This parameter may only be set to "ON" when an Uponor DEM WP module is connected.

This function is only active in comfort mode, ECO mode and programmed operation.

FROST PROTECT

To protect the heating system from frost, start the heating circuit pumps at the selected frost protection temperature; the reverse hysteresis is 1K.

MAXIMUM MIXER TEMPERATURE

Setting range 20 °C to 90°C.

This setting limits the ﬂow temperature of the mixer circuit. For example, if a higher set ﬂow temperature is calculated from the mixer circuit data, the max. set mixer ﬂow temperature will be used to control and regulate to this value.

FIXED VALUE OPERATION

The heat pump return is regulated to the set ﬁxed value. The switching time program will then be ignored. The various positions of the program selector will then only affect the mixer circuit (if installed). When the program selector is set to standby and a ﬁxed temperature has been selected the frost protection is activated and the compressor is switched off. Summer logic remains disabled with ﬁxed temperature control. This means that the heating circuit pump is not switched off for the direct heating circuit.

REMOTE CONTROL FE7

This menu item is only displayed when the FE7 remote control is connected.

HEATING CIRC PRESELECTION

The FE7 remote control can be selected for both heating circuits.

This parameter lets you choose which heating circuit the remote control is to act on. Depending on the remote control preselection, the actual room temperature can be checked under INFO / SYSTEM / ROOM TEMPERATURE.

ROOM INFLUENCE

Standard setting 5 adjustable from ---- via 0 to 20 Dashes (----) in the display:

With the FE7 remote control connected, the room temperature sensor only serves to record and display the actual room temperature; it has no inﬂuence on the actual control. The remote control can be used to adjust the room temperature for heating circuit 1 or 2 by ± 5 °C in automatic mode only. This set value adjustment applies to the current heating time, not to the setback time.

At the same time, the setting "0 to 20" serves to control the room temperature-dependent night setback. This means that the heating circuit pump is switched off at the point of changeover from the heating into the setback phase. It remains off until the actual room temperature falls below the set room temperature. After this, the system continues to regulate in weather-compensated mode.

If you want the room temperature to be taken into account, set the room temperature sensor inﬂuence to a value > 0. The room sensor inﬂuence has the same effect as the outside temperature sensor has on the return temperature, except that the effect is 1 to 20 times greater, depending on the factor set.

- Room temperature-dependent return / ﬂow temperature

with weather compensation

With this type of control, a control cascade is formed from both weather-compensated and room temperature dependent return/ ﬂow temperature control. This means that the weather-compensated return/ﬂow temperature control sets a default return/ﬂow temperature that is corrected by the overriding room temperature control in accordance with the following formula:

∆ϕ

= (ϕ

R

RSOLL

− ϕ

RIST

) * S * K

Because a substantial proportion of the control is already handled by the weather-compensated control, the room temperature sensor compensation factor K can be set lower than with pure room temperature control (K=20). The ﬁgure indicates the control method with the set factor K=10 (room inﬂuence) and a heating curve S=1.2.

- Room temperature control with weather-compensation

This type of control offers two main beneﬁts:

Incorrectly set heating curves are corrected by the room sensor inﬂuence K; whilst the smaller factor K means the control unit works in a more stable manner.

However, observe the following for all control units with room temperature sensor inﬂuence:

- The room temperature sensor must capture the room temperature accurately.

- Open doors and windows greatly affect the control result.

- All radiator valves in the lead room must be fully open at all times.

- The temperature inside the lead room affects the entire heating circuit.

If you want the room temperature to be taken into account, set the room temperature sensor inﬂuence to a value > 0.

ROOM CORRECTION

You can use this parameter to calibrate the measured room temperature.

PUMPCYCLES

- Heating circuit pump control

The PUMP CYCLES parameter only applies to the direct heating circuit1, i.e. for heating circuit pump 1.

This parameter can be switched ON or OFF. In the OFF position, the heating circuit pump will not cycle. It will operate constantly. It is only switched off in summer mode.

As soon as you set the parameter to ON, the heating circuit pump will be switched in line with a ﬁxed temperature curve for the outside temperature.

The heating circuit pump start pulse is always 5minutes.

The heating circuit pump for heating circuit 1 always starts with each heat pump start. The pump runs on for 5 minutes after the heat pump has been shut down. This is where the start-up duration is brought to bear, e.g.at an outside temperature of 5°C, the pump starts 3 times per hour for 5minutes respectively.

DHW LEARNING FUNCTION

Setting OFF

When heating DHW, the system automatically adjusts itself to the required DHW temperature (self-learning function).

The electric emergency/booster heater will be added as a booster stage as soon as the heat pump is shut down in DHW mode via the HP sensor or via the hot gas temperature limit (130 °C). If the ﬂow temperature of 70°C is achieved in this operating mode, DHW heating will be terminated, and the set DHW temperature is overwritten with the actual DHW temperature.

Setting ON

As soon as the heat pump is shut down in DHW mode via the HP sensor or the hot gas temperature limit (130 °C), DHW heating is terminated and the set DHW temperature will be overwritten with the current actual DHW temperature. This operating mode saves energy, as DHW is exclusively heated by heat pump.

DHW CORRECTION

Set the COOLING parameter to ACTIVE COOLING.

Note

The COOLING parameter will only be shown if an FEK or FE7 remote control is connected. Cooling mode is only possible in summer mode.

The WPC with the WPAC 2 cools in 2 stages:

Stage 1 (source pump)

Heat is extracted from the heating circuit and is passed to the heat source system.

Stage 2 (source pump + compressor)

In addition, the refrigerant circuit extracts heat from the heating circuit and transfers it to the heat source system.

DHW heating

DHW heating always has priority. As long as the actual temperature has not dropped below the set ﬂow or room temperature, active cooling continues even during DHW heating, and any extracted heat is transferred to the DHW. If there is no cooling demand, DHW is conventionally heated via the heat source system.

Cooling mode with the FE7

The FE7 remote control is not equipped with dew point monitoring. It can therefore only be used in conjunction with fan convectors with condensate drain. The cooling mode parameter must be set to FAN.

Cooling mode with the FEK

The FEK remote control is equipped with dew point monitoring, and can therefore be used with area heating systems (e.g. underﬂoor/wall heating systems, etc.). The COOLING parameter must be set to AREA COOLING. The set ﬂow temperature is compared with the captured dew point temperature, so the actual temperature never drops below the dew point. When using fan convectors with the FEK remote control, set the COOLING parameter to FAN COOLING.

In the COOLINGparameter, you can select the following cooling modes for the FE7 and the FEK:

- Room temperature Cooling mode starts when the selected room temperature is exceeded (output COOLING=230 V). Cooling mode is stopped when the actual room temperature drops 2K below the set temperature. (output COOLING=0 V)

20 | WPC | WPC cool www.stiebel-eltron.com

OPERATION

Menu structure

- Flow temperature and hysteresis Cooling mode is regulated via the selected ﬂow temperature. The brine pump starts at: [Flow temperature + hysteresis] Brine pump off when the actual temperature drops below the ﬂow temperature. The [ﬂow temperature+hysteresis] should be at least 3 K < room temperature. Lower ﬂow temperatures cause a more rapid cooling of the room. On the setting AREA COOLING, as soon as the determined dew point temperature is + 2 K higher than the set ﬂow temperature, that temperature will be overridden with the dew point temperature and acts as control variable. The brine pump starts at [entered or newly determined ﬂow temperature + hysteresis]. If the actual ﬂow temperature drops below the entered or newly determined ﬂow temperature, the source pump stops and cooling mode is terminated. The cooling signal remains active.

- Dynamic The Dynamic can be adjusted from 1 to 10. It describes the delay and changeover between passive cooling and active cooling, whereby active cooling is started sooner, the smaller the value.

9. Appliance description

9.1 Mode of operation

The heat exchanger on the heat source side (evaporator) extracts natural heat from the heat source. This extracted energy and the energy drawn by the compressor drive is transferred to the heating water by a heat exchanger on the heating water side (condenser). Subject to the heat load, the heating water is heated up to +60°C. The DHW is heated via the internal indirect coil inside the DHW cylinder.

The electric emergency/booster heater starts if the high pressure sensor or the hot gas limiter responds during DHW heating. In addition it covers any residual heat demand, if the heating system demand exceeds the heat pump output.

Note

The appliance is designed for internal installation, except in wet areas.

 Never install the appliance directly below or next to

bedrooms.

 Protect pipe transitions through walls and ceilings with an-

ti-vibration insulation.

The room in which the appliance is to be installed must meet the following conditions:

- No risk from frost.

- The room must not be subject to a risk of explosions arising from dust, gases or vapours.

- When installing the appliance in a boiler room together with other heating equipment, ensure that the operation of other heating equipment will not be impaired.

- The volume of the installation room should be at least

13.8m³.

- Load-bearing ﬂoor (for the weight of the unit, see chapter "Speciﬁcation / Data table").

 For installation on ﬂoating screeds, make provisions for a

quiet heat pump operation.

 Isolate the installation surface.

Commissioning

13. Commissioning

Only qualiﬁed contractors may carry out adjustments on the heat pump manager commissioning report, commission the appliance and instruct the owner in its use.

Commissioning should be carried out in accordance with these operating and installation instructions. Our customer service can assist with commissioning, which is a chargeable service.

Where this appliance is intended for commercial use, the rules of the relevant Health & Safety at Work Act may be applicable for commissioning. For further details, check your local authorising body.

13.1 Checks before commissioning

Before commissioning check the points detailed below.

13.1.1 Heating system

- Have you ﬁlled the heating system to the correct pressure?

- Have you closed the quick-action air vent valve of the multi function assembly (MFG) again after venting?

Material losses

!

Observe the maximum system temperature in underﬂoor heating systems.

13.1.2 Heat source

Material losses

!

With an underﬂoor heating system, never use the heat pump to dry the screed as this places such a high demand on the heat source that the frost protection function may kick in. See menu "PROGRAMS / HEAT-UP PROGRAM".

13.1.3 Temperature sensor

- Have you correctly positioned and connected the outside temperature sensor and the return temperature sensor (in conjunction with a buffer cylinder)?

13.1.4 High limit safety cut-out

At ambient temperatures below -15 °C the high limit safety cut-out of the multi function assembly may respond.

 Check whether the high limit safety cut-out has tripped.

1

13.1.5 Power supply

- Have you correctly connected the power supply?

- If no fault message is displayed when voltage is applied to the heat pump power supply (mains), then the rotating ﬁeld is correctly connected. If the fault message NO OUTPUT appears, reverse the rotational direction of the compressor.

13.2 Heating curve adjustment during commissioning

The efﬁciency of a heat pump decreases as the ﬂow temperature rises. Therefore adjust the heating curve with care. A heating curve that is set too high leads to the zone or thermostatic valves closing and the minimum ﬂow rate required for the heating circuit may not be achieved.

The following steps will help you to adjust the heating curve correctly:

 Fully open thermostatic or zone valves in a lead room (e.g.

living room or bathroom). We do not recommend installing thermostatic or zone valves in the lead room. Control the temperature for these rooms via remote control.

 At different outside temperatures (e.g. -10 °C and +10 °C),

adjust the heating curve so the required temperature is achieved in the lead room.

If the room temperature in spring and autumn is too low (outside temperature approx. 10 °C ), the SET ROOM TEMP parameter must be raised.

Note

If no remote control is installed, raising the SET ROOM TEMP parameter leads to a parallel offset of the heating curve.

If the room temperature is not high enough at low outside temperatures, increase the heating curve parameter.

If the heating curve parameter has been raised, adjust the zone valve or thermostatic valve in the lead room to the required temperature when outside temperatures are high.

If the actual temperature drops below the minimum source temperature, the compressor is switched off and the idle time is set. The compressor is enabled again after the idle time has expired and the ﬁxed hysteresis of 2 K has been exceeded.

This fault, i.e. MIN SOURCE T, is indicated in the display by a ﬂashing warning triangle, and entered into the fault list.

The source pump is always started 30 seconds earlier than the compressor, which starts when there is a heat demand coming from the central heating or DHW side.

Note

The source pump runs on for 60 seconds after the heat pump has been shut down.

BRINE PUMP RATING

Here you can set the brine pump ﬂow rate.

The heat source ﬂow rate is set via the temperature differential of the heat source circuit.

At a brine inlet temperature <10°C, a regeneration of the heat source system can be implemented in conjunction with the extractor module and ethylene glycol or propylene glycol as brine. The settings enable you to determine the run-on time of the brine pump after the heat pump has been shut down. The values stated correspond to the run-on time in minutes at an average brine inlet temperature of 0 °C.

If the brine inlet temperature rises, the run-on time of the source pump is reduced as a result. If the brine inlet temperature drops, the run-on time increases. From a brine inlet temperature of 10 °C, the run-on time will always be at least one minute.

Note

The heat pump can only be operated as a ground source heat pump.

CNTRL DYNAMIC

Setting range 0 to 30

The selected control dynamic is a measure of the switching interval between the compressor and the electric emergency/booster heater. Normally, the preselected dynamic must be sufﬁciently fast and without oscillation. Heating systems that respond quickly require a lower value, whilst very slow responding systems require a higher value to be set.

HP SENSOR MAX

Maximum high pressure

Setting range 38 bar to 40 bar.

DHW circuit pump rating

Set the maximum ﬂow rate here. If this is noisy, reduce the ﬂow rate.

13.3.6 COMPRESSOR

IDLE TIME

After a heat pump has been shut down, an idle time is set to protect the compressor. The default idle time of 20 minutes should normally not be reduced. Where a reduction is required because of adjustments or repair work, reset the idle time again to 20 minutes after completing the necessary work.

SINGLE PHASE OPERATION

This parameter must always be set to OFF.

QUICK START

During commissioning, you can test the heat pump function by triggering a heat pump quick start. When navigating to this parameter, OFF is shown on the display. If you set it to ON and press "OK", a quick start is initiated. The respective pumps are switched on after the heat pump has started. The value of 60 seconds is visibly counted down to 0 on the display; then the display shows ON when the quick start begins.

After that, the heat pump and the associated buffer charging pump are switched on.

Shutting down

15. Shutting down

If the system is to be taken out of use, set the heat pump manager to standby. This retains the safety functions designed to protect the system (e.g. frost protection).

There is no need to shut the system down in summer. The heat pump manager has an automatic summer / winter changeover.

Material losses

!

Never interrupt the power supply, even outside the heating period. The system's active frost protection is not guaranteed if the power supply is interrupted.

Material losses

If the heat pump and frost protection are completely switched off, drain the system on the water side.

16. Troubleshooting

WARNING Electrocution

 Isolate the appliance from the power supply when

carrying out any work.

16.1 Fault display

Faults/errors in the system or in the heat pump are indicated on the display. For heating system and heat pump troubleshooting and analysis, all important process data and bus subscribers can be called up under DIAGNOSIS and a relay test can be carried out.

 For troubleshooting, analyse all available parameters before

opening the heat pump control panel.

The heat pump manager will not indicate whether the electric emergency/booster heater high limit safety cut-out has responded. The high limit safety cut-out can be reset by your contractor through pressing the reset button. The high limit safety cut-out response is generally caused by air in the heating circuit or an inadequate heating ﬂow rate.

Fatal error in heating mode only; 5 faults within 5 minutes of compressor runtime. If the system has been shut down five times within the operating time (5 minutes), the fault will be added to the fault list and the system will be permanently shut down. Generally, a shutdown via HP SENSOR MAX is a controlled shutdown that is only displayed for information and for the duration of the idle time, i.e. it is not entered into the fault list. Only frequent shutdowns over a short period of time point towards a fault and are therefore entered into the fault list.

The compressor will be stopped for the minimum idle time if a hot gas temperature of 120°C is exceeded. This is a normal controlled shutdown that is not entered into the fault list. The reason for the shutdown is displayed for information during the idle time.

After the compressor has started and a delay of 15 seconds has elapsed, the system checks whether relay K9 is open. If this is the case, a HP limit switch has responded. The fault is added to the fault list and the system is permanently shut down.

The system will be permanently shut down after the fault has occurred five times within the operating time (idle time x 50 plus 20 minutes). The fault is added to the fault list after it has occurred for the first time.

Minimum source temperature The defined minimum source temperature was not reached. The fault is added to the fault list. The compressor starts again after the selected idle time has expired.

Each time the compressor is switched off, the system checks af ter 10 seconds whether the relay K9 is open. If this is the case, then a contactor is stuck. The fault is added to the fault list and the system is permanently shut down.

After the compressor has started, the pressure must have risen by 2 bar within 10 seconds. If this is not the case, a fault has occurred. The fault is added to the fault list if this is its first occurrence, and the system is permanently shut down.
