3. Appliance description

The WPF is a heating heat pump designed as a ground source 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, enriched by the electric energy drawn by the compressor. Subject to the heat source temperature, the heating water can be heated up to a ﬂow temperature of 60 °C.

Inside the WPF, a heating circuit pump and a three-way valve have been integrated for diverting the ﬂow either to the heating circuit

OPERATION

Operation

or the DHW circuit. DHW is heated by pumping the heating water, which has been heated by the heat pump, 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 is undershot in mono mode operation, the electric emergency/booster heater is activated to safeguard heating operation and the provision of high DHW temperatures. If the same thing happens in mono energetic operation, the electric emergency/booster heater is activated as a booster heater.

The equipment is regulated by an integral, weather-compensated return temperature control (WPMiw heat pump manager).

The WPMiw also regulates the DHW heating to the required temperature. DHW heating will be completed automatically by an integral electric booster heater, if either the high pressure sensor or the hot gas limiter of the heat pump responds during DHW heating, subject to the ECO function being enabled. Subject to the ECO function being enabled, the DHW heating will terminate and the set DHW value overwritten with the actual DHW temperature that has been achieved.

The WPMiw also controls the integral electric booster heater. No other heat source can be switched.

3.1 Energy saving tip

- Heat pumps operate with particular economy and environmental responsibility when they work with a maximum ﬂow temperature of 35 °C. Low ﬂow temperatures can be achieved by using area heating systems (e.g. underﬂoor heating or wall heating systems).

- Size radiators so that the maximum required ﬂow temperature does not exceed 45 °C.

- Activating the control parameter “Pump cycling” can reduce the power drawn by the circulation pump. In this connection, refer to your local heating contractor.

- When activating the “DHW ECO” parameter, the heat pump heats DHW exclusively on its own, i.e. without the additional electric booster heater. In that case, the DHW temperature is automatically limited to that value, which the heat pump can actually achieve. If, for reasons of pasteurisation, you want to heat the cylinder to 60 °C at least once every day, activate the “PASTEURISATION” parameter. In this connection, refer to your local heating contractor.

Summary of WPMiw functions

- RS 232 interface for adjustment and monitoring via a PC

- System expansion through the FEK and FE7 remote control units

- Input of the system and heat pump frost protection limits

- At least 24 h power reserve for the clock

- Automatic pump kick-start

- Reset option

- Stored fault list with precise fault code indication, together with date and time display

- Fast and precise fault diagnosis with a system analyser incl. temperature scanning of heat pumps and peripherals without additional equipment

- Factory settings for time switch programs for all heating and DHW circuits

Adjustment of programmed changeover between day and setback mode

The ﬁgure shows a standard heating curve with a slope of 0.8, relative to a set room temperature for day mode of 20°C. The bottom curve is setback mode. The set room temperature is reduced to 15 °C for setback mode. The heating curve is shifted down parallel to the original curve.

Adapting a heating curve

Example:

During spring and autumn, the temperature of a building’s heating system is too low at an outside temperature between 5 °C and 15°C, despite open radiator valves, but is OK at outside temperatures of ≤ 0 °C. This problem can be remedied with a parallel offset and a simultaneous reduction of the heating curve.

Prior to this adjustment, heating curve 1.0 was adjusted, relative to a set room temperature of 20 °C. The dotted line indicates the modiﬁed heating curve at 0.83 and a modiﬁed set room temperature at 23.2 °C.

4.5.8 HEATING PROG

The HEATING PROG parameter enables you to determine when and how often the appliance heats to the set day values for heating circuit 1 and 2. At all other times, the appliance heats to the set night temperature. You will have already selected the set values under menu item ROOM TEMP HC1/2.

You can adjust your heating system as follows:

- for each individual day of the week (Monday, ..., Sunday)

- Monday to Friday (Mo – Fr)

- Saturday and Sunday (Sa – Su)

- the whole week (Mo – Su)

You can adjust three switching time pairs (I, II, III) for each of these options.

Example:

For heating circuit 1, your heating system should provide heat daily from Monday to Friday at two different times, i.e. from 05:30 h until 08:30 h as well as from 14:00 h until 22:00 h. For the weekend, your heating system should provide heat from 08:30 h until 21:00 h.

4.5.9 DHW programs

The DHW PROGRAM parameter enables you to select the times when the appliance will control DHW heating using the set day value. At all other times, the appliance controls DHW heating using the set night value. You will have already selected the set values under system parameter DHW TEMP. bereits eingestellt.

You can adjust your DHW heating as follows:

- for each individual day of the week (Monday, ..., Sunday)

- Monday to Friday (Mo – Fr)

- Saturday and Sunday (Sa – Su)

- the whole week (Mo – Su)

You can adjust three switching time pairs (I, II, III) for each of these options.

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

Example:

You want to heat up DHW daily at two different times, i.e. from 22:00 h until 06:00 h the following day, and then from 08:00 h until 09:00 h.

The day begins at 00:00 h; therefore begin programming for this example at 00:00 h. The ﬁrst switching times pair runs from 00:00 until 06:00 h. The second switching time pair runs from 08:00 until 09:00 h. The third switching times pair runs from 22:00 h until 23:59 h.

8.1 Mode of operation

Environmental energy is extracted by the heat exchanger on the heat source side (evaporator). Any energy extracted is transferred, together with the energy drawn by the compressor drive, to the heating water by a heat exchanger on the heating water side (condenser). Subject to the heat load, the heating water can be heated to +60°C. The DHW is heated via the internal indirect coil inside the DHW cylinder.

The electric booster heater (internal HS 2) starts if the high pressure sensor or the hot gas limiter responds during DHW heating. In addition it can cover any residual heat demand, if the heating system demand exceeds the heat pump output.

10.4.3 Connection and ﬁlling with brine

Prior to connecting the heat pump, check the heat source circuit for possible leaks, and ﬂush thoroughly.

Calculate the volume of the heat source circuit. The brine volume of the heat pump under operating conditions can be found in the data table (see chapter “Speciﬁcation”).

The overall volume is equal to the required amount of brine made by mixing undiluted ethylene glycol and water. The chloride content of the water must not exceed 300 ppm.

Mixing ratio

The brine concentration varies when using a ground collector or a geothermal probe as a heat source.

The mixing ratio can be found in the table below.

Ethylene glycol Water

Geothermal probe 25 % 75 % Geothermal collector 33 % 67 %

Charging the brine circuit

Note

The WPF S series does not have a brine pressure switch.

10.4 Installing the heat source system

Design the heat source system for the ground source heat pump in accordance with the technical guides.

10.4.1 Permitted brine:

- Heat transfer medium as concentrate on an ethylene glycol base, part no: 231109

- Heat transfer medium as concentrate on an ethylene glycol base, part no: 161696

10.4.2 Circulation pump and required ﬂow rate

Use a circulation pump with compound-ﬁlled windings to supply the brine, to prevent an earth short circuit through condensate in the electrical part of the pump (cold water version).

Size the circulation pump in accordance with the system-speciﬁc conditions, h. i.e. nominal ﬂow rate and pressure drop must be taken into consideration (see “Speciﬁcation”).

An adequate ﬂow rate must be safeguarded at every possible brine temperature, i.e.:

Nominal ﬂow rate at a brine temperature of 0°C with a tolerance of +10%.

Note

26�03�01�1574

The brine/water heat pump is equipped with a brine pressure switch in the brine circuit. The brine pressure switch prevents brine getting into the ground if there is a leak in the brine circuit.

If the pressure in the brine circuit falls below 0.7bar, the brine pressure switch turns the heat pump off. In order for the heat pump to be enabled again, the pressure must be raised to at least

1.5bar while the heat pump is on standby.

To prevent the brine pressure switch turning the heat pump off when there is no leak, charge the heat source side of the heat pump during installation with a minimum pressure of >1.5bar.

 Fill the system according to the following curve.

 Insulate the brine lines with diffusion-proof thermal

insulation.

Note

The brine pressure switch is bridged to the power supply utility contact at the factory.

 To activate the brine pressure switch, remove the

jumper.

10.5 Heating water connection

The heat pump heating system must be installed by a qualiﬁed contractor in accordance with the water installation drawings that are part of the technical documents.

 Thoroughly ﬂush the pipework before connecting the heat

pump. Foreign bodies, such as welding beads, rust, sand, sealant, etc. can impair the operational reliability of the heat pump.

 Connect the heat pump on the hot water side. Check for

tightness.

Ensure the correct connection of the heating ﬂow and return.

Provide thermal insulation in accordance with applicable regulations.

For sizing the heating circuit, note the maximum available external pressure differential.

10.6 Oxygen diffusion

diffusion may lead to corrosion on the steel components of the heating system (e.g.on the indirect coil of the DHW cylinder, on buffer cylinders, steel radiators or steel pipes).

 In the event of oxygenation, separate the heating system be-

tween the heating circuit and the buffer cylinder.

Material losses

!

The products of corrosion (e.g.rusty sludge) can settle in the heating system components, which may result in a lower output or fault shutdowns due to reduced cross-sections.

10.7 Filling the heating system

Fill the heating system via the drain.

Water quality

A ﬁll water analysis must be carried out before the system is ﬁlled. This may, for example, be requested from the relevant water supply utility.

Material losses

!

To avoid damage as a result of scaling, it may be necessary to soften or desalinate the ﬁll water. The ﬁll water limits speciﬁed in chapter "Speciﬁcation / Data table" must always be observed.

 Recheck these limits 8-12 weeks after commission-

ing and as part of the annual system maintenance.

Note

With a conductivity >1000μS/cm, desalination treatment is recommended in order to avoid corrosion.

Note

Suitable appliances for water softening and desalinating, as well as for charging and ﬂushing heating systems, can be obtained via trade suppliers.

10.9 Minimum ﬂow rate of heat sink for WPF 5-16 basic

The heat pump is designed in such a way that no buffer cylinder is required to provide hydraulic separation of the ﬂow in the heat pump circuit and the heating circuit in conjunction with space heating systems.

However, in conjunction with radiators or an installation with several heating circuits, the use of a buffer cylinder or a low loss header is recommended.

The WPF 13 and 16 appliances must, in any case, always be operated with a buffer cylinder or a low loss header.

Risk of damage!

!

The minimum ﬂow rate to ensure perfect heat pump operation must be maintained at every operating point of the heat pump.

10.9.1 Minimum ﬂow rate without buffer cylinder

The minimum ﬂow rate is set using the temperature differential of the heating system.

Set the heating circuit pump to ∆p-constant. Set ∆p-constant to a value at which the temperature reaches or falls below the maximum temperature differential.

 Check the ﬁnal setting in DHW mode and adjust if required.  Fully open the overﬂow valve.  Close the overﬂow valve one turn at a time until the return to

the heat pump or the installed radiators become noticeably warm.

If no overﬂow can be detected in the overﬂow valve using the temperature sensor, close the heating circuit and heating circuit valves and check the overﬂow valve is working.

Individual room control via remote control FE7 or FEK

In this case, one or more heating circuits in the heating system must be left open. The open heating circuit(s) should be installed in the lead room (room in which the remote control is installed, e.g. the living room). The individual room can then be controlled via the FE7 or FEK remote control, or indirectly by adjusting the heating curve. The other rooms can be equipped with zone valves or thermostatic valves.

 Fully open the heating circuit(s).  Isolate by temporarily removing the fuse from the second in-

ternal heat source (DHC electric booster heater).

 Operate the appliance in heating mode.  Set the head of the circulation pump to a level that safe-

10.10 Flow rate of heat sink for WPF 5-10 S basic

10.10.1 Circulation pump (cylinder primary pump)

The cylinder primary pump is integrated into the WPF. Consider the available external head of 2.8 m when sizing the anti-vibration mounts and the pipework between the heat pump and the buffer cylinder.

When utilising the WPF for DHW heating, ensure that the connection between the heat pump and the DHW cylinder is sized so that the total pressure drop outside the heat pump is less than the available external head of 2.8 m.

10.10.2 Circulation pump (heating circuit pump)

If no cylinder (buffer cylinder) is used, consider the maximum external pressure of 280 hPa when sizing the heating circuit. Safeguard the nominal ﬂow rate of the heat pump under all operating conditions of the heating system by installing an overﬂow valve.

10.11 DHW heating

For DHW heating, a DHW cylinder with internal indirect coil is required. The minimum coil surface area required is 3 m³.

A three-way diverter valve is integrated into the WPF between the DHW heating circuit and the central heating circuit.

11.1.5 Power supply

- Have you correctly connected the power supply?

- The compressor turns in the right direction if, when voltage is applied to the heat pump power supply (mains), no fault message appears in the display. If the fault message NO OUTPUT appears, reverse the rotational direction of the compressor.

11.2 Heating curve adjustment during commissioning

The efﬁciency of a heat pump decreases with rising ﬂow temperature. The heating curve should therefore be adjusted with care. Heating curves that are adjusted too high lead to the zone and thermostatic valves closing, which may lead to the minimum ﬂow rate required for the heating circuit not being 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 set in the lead room.

Standard values for a start:

Parameter Underfloor heating

system

Heating curve 0,4 0,8 Controller dynamics 5 15 Room temperature 20 °C 20 °C

Heating system with radiators

Note

If no remote control is installed, raising the parameter “room temperature” leads to a parallel offset of the heating curve.

Increase the parameter “HEATING CURVE” if the room temperature is not high enough when outside temperatures are low.

If the parameter “Heating curve” has been raised, adjust the zone or thermostatic valve in the lead room to the required temperature at high outside temperatures.

26�03�01�1893

Note

Never reduce the temperature in the entire building by closing all zone or thermostatic valves, but by using the setback programs.

11.3 Operation and control

Appliance and system damage

!

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

The system should not be switched off in summer. The heat pump manager has an automatic summer / winter changeover.

11.4 Taking the appliance out of use

If the appliance 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).

Appliance and system damage

!

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

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

11.6 Heat pump manager commissioning

General information

Not only the adjustments at control level 2 but also the system-speciﬁc parameters must be determined as part of commissioning the heat pump system. These parameters are adjusted at control level 3, access to which is protected by code.

Note

The heat pump manager should be in standby mode during commissioning. This prevents an uncontrolled heat pump start. Please remember to reset the system into its last operating mode.

Check all parameters in sequence, and enter all selected values into the column (system value) provided in the commissioning report.

Note

Not all adjustments take immediate effect. Some adjustments only become effective in certain situations or after a delay.

1 CODE

Enter the correct four-digit code to change parameters at control level 3. The factory-set code is 1 0 0 0.

After pressing PRG (indicator illuminates), the ﬁrst digit can be selected by turning the rotary selector. Pressing PRG again conﬁrms the value, then the second digit of the code begins to ﬂash. Turning the rotary selector enables the second digit of the code to be entered, etc. When all four digits have been entered correctly, four lines appear in the display. This enables access to control level 3, and the display shows CODE OK. Closing and re-opening the ﬂap requires that the code is entered again. Checking settings does not require the code to be entered.

2 LANGUAGE

Here you can select the menu language.

 Press PRG.  Select required language.  Conﬁrm with PRG.

5 EMERGENCY MODE

Characteristics in case of “Fatal Error” conditions in conjunction with the emergency operation:

The EMERGENCY MODE parameter can be set to ON or OFF.

Emergency mode set ON:

The program selector automatically changes over to emergency mode as soon as faults occur and the heat pump fails.

Emergency mode set OFF:

The booster heater takes over the frost protection of the central heating system, as soon as faults occur and the heat pump fails. Users can then select emergency mode on their own initiative.

6 COOLING MODE

WPF 5 - 16

This equipment is designed for DHW and central heating. In the delivered condition, the COOLING MODE parameter is set to OFF. Cooling mode is only possible in conjunction with a suitable hydraulic circuit.

Appliance and system damage

!

The COOLING MODE parameter must only be set if there is a suitable hydraulic circuit.

Note

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

The WPF with a suitable circuit 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 cooling circuit extracts heat from the heating circuit and transfers it to the heat source system.

3 CONTRAST

The display contrast can be adjusted here.

 Use the rotary selector to adjust the contrast.

4 DISPLAY

Select, what will be displayed when the programming unit ﬂap is closed. The options are:

- outside temperature,

- return temperature,

- day and time,

- DHW temperature or

- mixer temperature.

34 | WPF basic www.stiebel-eltron.com

DHW heating

DHW heating always has priority. As long as the actual temperature has not dropped below the set ﬂow and 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 operation with the FE 7

The FE7 is not equipped with dew point monitoring. It can therefore only be used in conjunction with fan convectors with condensate drain. Set the cooling mode to FAN.

Cooling operation 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.). Set parameter 6 to AREA. The

INSTALLATION

Commissioning

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 MODE parameter to FAN.

The following settings for the FE 7 and the FEK can be selected for the cooling operation in parameter 6:

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

- Flow temperature and hysteresis The cooling operation 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. As soon as, with setting AREA, the determined dew point temperature is + 2 K higher than the selected ﬂow temperature, that temperature will be overridden with the dew point temperature and acts as controlled variable. The brine pump starts at [entered or newly determined ﬂow temp. + hysteresis]. The source pump stops and the cooling operation terminates, if the actual ﬂow temperature lies below the entered or newly determined ﬂow temperature. The cooling signal remains active.

- Dynamic Dynamics can be adjusted from 1 to 10. It describes the delay between stage 1 and stage 2, whereby the second stage is started sooner, the smaller the value.

7 HEAT-UP PROG

Heat-up program for underﬂoor heating systems

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 respond. The electric emergency/booster heater must be used for the heat-up program. For this, set parameters HEATING LIMIT and DUAL-MODE HTG 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. This program is started with the parameter HEAT-UP PROG and with the setting ON. The system then heats to the selected low end temperature (parameter LOW END TEMP). The low end temperature is then held for the set period (parameter LOW END DURAT). After expiry of this period, the system heats with an increase K/day (parameter INCREASE/DAY) to the maximum low end temperature (parameter MAX. HEAT-UP T) and is held at the maximum temperature via the selected time (parameter MAX T DURATION). After expiry of this period, the system reduces the temperature back to the low end temperature in the same stages as per heat-up. This concludes the heat-up program. As soon as two heating circuits are operational, both will be operated in accordance with this heat-up program (operation with buffer cylinder and mixer circuit). Direct heating circuit 1 (buffer circuit with return sensor) adopts the heat-up program’s set val-

ues. The actual temperature inside the buffer cylinder is higher at the heating ﬂow, since it is regulated via the return sensor. The mixer (heating circuit 2) regulates the temperature back down to the selected set values in the heat-up program (low end temperature and maximum temperature).

Y Temperature X Time 1 Maximum temperature 2 Low end temperature 3 Low end temperature rise period 4 Increase K/day 5 Maximum temperature duration 6 Start 7 End

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

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

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

8 SUMMER MODE

The summer mode parameter allows you to select the time from when the heating system should change into summer mode. Summer mode can be switched ON or OFF. This function offers two adjustable parameters.

The “Building Type” parameter determines, subject to building type (setting 1, 2 or 3), an adjusted outside temperature. If the calculated outside temperature ≥ the selected outside temperature, both heating circuits (if installed) switch to summer mode; reset hysteresis –1 K. SUMMER MODE is shown in the display when the ﬂap is closed.

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

OUTSIDE TEMP parameter:

Available outside temperature 10 °C to 30 °C

BUILDNG TYPE parameter:

Setting 1: Mild adjustment of the outside temperature (averaging over a 24 h period), e.g. timber construction with rapid heat transfer.

84�03�01�0038

www.stiebel-eltron.com WPF basic | 35

INSTALLATION

Commissioning

Setting 2: Moderate adjustment of the outside temperature (averaging over a 48 h period), e.g. solid construction with thermal insulation and average heat transfer.

Setting 3: Severe adjustment (averaging over a 72 h period) of the outside temperature, e.g. house with slow heat transfer.

9 PUMP CYCLES

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 set ON or OFF . In setting OFF the heating circuit pump will not cycle. Instead, it will operate constantly and is only switched off in summer mode.

The heating circuit pump start will be controlled in accordance with a ﬁxed temperature curve of the outside temperature, as soon as this parameter is set to ON.

The heating circuit pump start pulse is always ﬁve 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 switched OFF. Now the start-up duration is brought to bear, e.g. at an outside temperature of 5 °C, the pump starts three times per hour for ﬁve minutes respectively.

Pump kick

To prevent the pumps seizing up, over the summer for example, when a pump has been switched off for 24 hours it will be switched back on for 10 seconds. This applies to all pumps.

Heating circuit pump control with connected FE7/FEK remote control

In conjunction with the FE7 or FEK remote control, the respective heating circuit pump is switched off and the mixer moves to “Closed” in accordance with the switching condition

ϕ

ACTUAL room >ϕSET room

the respective heating circuit pump is switched OFF and the mixer moves to “CLOSE”. This only applies if the room sensor inﬂuence is set to K > 0. Reverse control is subject to the following condition:

11 FIXED VALUE

Fixed value temperature

The heat pump return is controlled at the set ﬁxed value. The switching time program will then be ignored. The various program switch positions will then only affect the mixer circuit (if installed). The frost protection is activated and the compressor is switched OFF when the program selector is set to “Standby” and a ﬁxed temperature has been selected. Summer logic remains disabled with ﬁxed temperature control. This means that the heating circuit pump is not switched off for the direct heating circuit. With the ﬂap closed, the display shows the ﬁxed temperature program, in other words always showing the heating times.

12 SOURCE

Frost protection for brine|water heat pumps

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

Ethylene glycol as brine (including polypropylene glycol) means that the heat pump frost protection is inactive. Responses by the frost stat no longer have any inﬂuence.

Potassium carbonate as brine (STIEBEL ELTRON heat transfer medium) means that the heat pump frost protection is inactive. This ensures that the source pump is started at an outside temperature of -10°C, even if the heat pump is idle. It is switched OFF again at an outside temperature of – 8 °C.

ALM 0, 30, 60, 120 and 180

(Only in conjunction with the extractor module LWM 250)

At a brine inlet temperature of < 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. Settings enable the determination of 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.

Troubleshooting

13. Troubleshooting

13.1 Fault display

Faults/errors in the system or in the heat pump are indicated on the display. All parameters required for an in-depth system analysis can be checked under the system menu items COMMISSIONING and TEMPERATURES. For troubleshooting, analyse all available parameters before opening the heat pump control panel.

The controller will not indicate that the 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.

 Check the heating ﬂow rate and ventilate the heating system.

13.1.1 Heat pump-speciﬁc or hardware faults

All faults are displayed.

Example: High pressure fault

HP SENSOR MAX

Observe the list under system parameter TEMPERATURES.

Sensor Fault code

Outside temperature E 75 Remote control E 80 Actual DHW temperature E 76 Actual heat pump return temperature (H1) E 73 Actual mixer flow temperature (H2) E 70 Actual heat pump flow temperature E 72 Actual source flow temperature E 71 High pressure sensor E 130 LP sensor E 128

13.1.3 Fault message with DCO enabled

In connection with the dial-up connection controller DCO enabled, the sensor faults listed above result in the transmission of the error codes (E75 to E130) by SMS to the authorised recipient.

In addition, the following fault codes are transmitted as text message:

Contactor stuck E 20 No power E 21 Low pressure E 22 HIGH PRESSURE E 23 HP sensor max E 24

1

1 Fault message (ﬂashing)

All faults cause the heat pump to shut down. The idle period will be set and, with the exception of MAX HOT GAS T, ALl faults are written to the fault list.

13.1.2 Sensor break = sensor fault

SENSOR BROKEN

1

1 Fault message (ﬂashing)

Note

This fault code refers to temperature sensors that can be called up under the parameter TEMPERATURES. These faults are not entered into the fault list. The system will not be shut down. The display message will extinguish immediately after the fault has been removed.

13.1.4 Checking brine pressure

26�03� 01�1063

 Check brine pressure if the heat pump is blocked for more

than three hours (standby symbol ﬂashes [

 Check the brine pipe for leaks.  Remedy any leaks.  Recharge the system (see chapter “Installation/ Installation/

Installing the heat source system/ Connection and brine charging/ Charging the brine circuit”).

13.1.5 The heat pump does not run

The heat pump is in standby mode [

Remedy: Change to automatic mode

The power supply has been blocked; the standby symbol ﬂashes

]

[

26�03�01�1064

Remedy: Wait; the heat pump restarts automatically at the end of the blocking time.

There is no heat demand

Remedy: System parameter TEMPERATURES, check temperatures and compare the actual and set temperatures.

Possibly incorrect fuse rating

Remedy: See Speciﬁcation

]

]).

Note

Under these circumstances, you can only restart the heat pump after the fault has been removed and the heat pump has been reset (parameter WPM RESET).

Additional parameters available for system analysis:

Troubleshooting

Relay test:

Test all relays in the WPMiw

Analysis:

System analysis for checking all existing BUS subscribers

Reset HP:

Heat pump reset to clear all saved faults.

WPMiw reset options

Reset by turning the rotary selector from Auto to Reset and back again. All system-speciﬁc programs remain intact. The fault list will not be deleted.

Reset by turning the rotary selector from Auto to Reset and back again while holding down the PRG key. The display must show EEPR (EEPROM hardware reset). The WPMiw is reset into the delivered condition. The fault list will be deleted.

After a hardware reset, if the control ﬂap is closed, NO HEAT P PARA is displayed.

The heat pump type must be re-entered.

When the control ﬂap is opened, HEAT PUMP is displayed. After pressing the PRG button, the heat pump type can then be selected using the rotary selector. The heat pump type must be conﬁrmed by pressing the PRG button.

Note

The heat pump type can be found on the type plate.

The parameter SINGLE PHASE must be returned to ON on single phase appliances.

13.2 Resetting the high limit safety cut-out

If the heating water temperature exceeds 85°C, the electric emergency/booster heater shuts down.

13.3 Fault list parameter

Check and remove all faults in the fault list.

Fault display Reason for fault code triggered by control unit: Possible cause of fault/remedy

HP sensor max Controlled shutdown; no fault

LOW PRESSURE The system will be permanently shut down after the fault has occurred five times

CONTACT STUCK Each time the compressor is switched off, the system checks af ter ten seconds,

HIGH PRESSURE After the compressor has started, and after a delay of 15 seconds, masking checks,

NO OUTPUT

MIN SRCE TEMP The defined minimum source temperature was not reached.

MAX HOT GAS T Controlled shutdown; no fault

The fault will be written to the fault list and the system will be permanently shut down after the system has been shut down five times within the operating time (5 minutes). Generally, the shutdown via the 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.

within the operating time (idle time x 50 plus 20 minutes). The fault will be written to the fault list after it has occurred for the first time.

whether the relay K9 is open. A contactor is stuck, if that is the case. The fault is written to the fault list, and the system is permanently shut down.

whether the relay K9 is open. A HP limit switch has responded, if that is the case. The fault is written 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. A fault has occurred, if that is not the case, and the fault will be written into the fault list, if that is its first occurrence, and the system is permanently shut down.

The power supply utility has blocked the heat pump (see chapter “Installation/ Troubleshooting/ Fault indicators on the display/ The heat pump is not running”).

The fault is written to the fault list. The compressor starts again after the selected idle time has expired.

The compressor will be stopped for the minimum idle time if a hot gas temperature of 130 °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.

Only when a fault has been entered into the fault list: Monitor the flow temperature and check the HP sensor. Check the flow rate and the temperature on the heating side.

Check the flow rate and the layout of the source side. Check the refrigerant level.

Check contactors K1 and K2 and replace if required.

Monitor the flow temperature and check the HP sensor. Check the flow rate and the temperature on the heating side.

Compressor turns in the wrong rotational direction. Change the rotational direction by interchanging two supply cores.

No action required. If this message is still shown despite enabling by the power supply utility, the brine pressure switch has responded. Check the brine line for leaks and remedy any that are found. Subsequently recharge the system (see chapter "Installation/ Installation/ Installing the heat source system/ Connection and brine charging/ Charging the brine circuit").

Check the minimum, source temperature and change it if required. Check the source flow rate: Check source design.

This requires no action, as it is a controlled shutdown.

14. Maintenance

We recommend a regular inspection (to establish the current condition of the system), and maintenance if required (to return the system to its original condition).

If heat meters are installed, their sieves should be cleaned regularly.
