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
WPMiw heat pump manager
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.

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.

4.5.7 HEATING CURVES
HEATING CURVES
The HTG CURVE menu item enables you to adjust one HTG CURVE
each for heating circuit 1 and 2.
Note: Your contractor will have set up a building and system-specific optimum heating curve for every heating circuit. It relates to
the heat pump return temperature for heating circuit 1 and to the
mixer flow temperature for heating circuit 2.
When adjusting the heating curve on the heat pump manager, the
calculated set return or flow temperature, which is subject to the
outside temperature and the set room temperature, will be shown
at the top of the display.
As soon as a temperature has been preselected via the fixed temperature parameter at control level 3, heating circuit 1 will be
hidden, and the display will show FIXED VALUE with the relevant
temperature.

Adapting a heating curve
One heating curve can be adjusted for heating circuit 1 and heating
circuit 2 respectively.
Example:
At the factory, heating curve 0.6 is set up for heating circuit 1 and
heating curve 0.2 for heating circuit 2.
These heating curves relate to a set room temperature of 20 °C.

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.

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.

Appliance description
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
When removing the front cover ensure, that the cables, which
connect the heat pump manager with the control panel, are not
torn off.
Prior to connecting the heat pump, check the heat source circuit
for possible leaks, and flush thoroughly.
The same applies to the earth connection which electrically connects the front cover to the casing.
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.

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”).
Note
ff
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.
ff
To activate the brine pressure switch, remove the
jumper.
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.
ff
Fill the system according to the following curve.
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%.

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.
ff
Recheck these limits 8-12 weeks after commissioning 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.

Only qualified electricians must carry out the installation in accordance with these instructions.
DANGER Electrocution
Before any work, isolate the appliance from the power
supply at the control panel.
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.
ff
Connect the DHW flow of the appliance to the upper coil connection of the DHW cylinder (see Specification / Connections).
ff
Connect the DHW return of the appliance to the lower coil
connection of the DHW cylinder.
Permission to connect the appliance may need to be obtained from
your local power supply utility.

Commissioning is to be carried out in accordance with these installation instructions and the operating and installation instructions
of the heat pump manager. Our customer service can assist in the
commissioning, which is chargeable.
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.
After commissioning, complete the commissioning report that are
part of these instructions.
11.1 Checks before commissioning
Before commissioning check the points detailed below.
Appliance and system damage
In cooling mode, the WPF requires the FEK for area cooling systems, e.g. underfloor heating systems, chilled
ceilings, etc. Apart from the room temperature, it also
determines the dew point temperature to prevent condensation.
Connection array FEK
11.1.1 Heating system
-- Have you filled the heating system to the correct pressure,
and opened the quick-acting air vent valve?
!
System damage
Observe the maximum system temperature in underfloor
heating systems.
11.1.2 Heat source
!
1 2 3 4 5 6
System damage
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
respond. See also chapter “Commissioning the heat pump
manager / Parameter HEAT-UP PROG”.)

11.1.3 High limit safety cut-out
At ambient temperatures below -15 °C it may happen that the
high limit safety cut-out triggers the emergency/booster heater.
ff
Check whether the high limit safety cut-out has responded.
The FEK remote control enables you to change the set room temperature for heating circuit 1 or heating circuit 2 by ± 5 °C as well
as the operating mode. Connect it to terminals H, L, I and + at the
terminal block X2 of the appliance.

26_03_01_1893
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.
Note
Never reduce the temperature in the entire building by
closing all zone or thermostatic valves, but by using the
setback programs.

2 Electric emergency/booster heater
ff
Reset the high limit safety cut-out by pressing the reset
button.
11.1.4 Temperature sensor
-- Have you correctly located and connected the outside temperature sensor and the return temperature sensor (in conjunction with a buffer cylinder)?
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.
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.
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.

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

EMERGENCY MODE
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.
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
www.stiebel-eltron.com
Installation
Commissioning
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

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 valwww.stiebel-eltron.com
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).

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.

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

outside temperature, e.g. house with slow heat transfer.

PUMP CYCLES

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.

FIXED VALUE
Fixed value temperature
The heat pump return is controlled at the set fixed value. The

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

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

MIXER DYNAMIC
Mixer runtime
Setting range 60 to 240
In the OFF position there is no scanning via the source sensor
temperature.
This setting can be used to adapt the mixer characteristics. The
setting 60 to 240 means 6 K to 24 K control deviation.
The compressor shuts down and the idle time is set, when the actual temperature drops below the minimum source temperature.
The compressor is enabled again after the idle time has expired
and the fixed hysteresis of 2 K has been exceeded.
The system scans every 10 s, and the minimum ON time for the
mixer is 0.5 s. The mixer does not respond inside the dead zone
of ±1 K from the set value.
This fault, i.e. MIN SRCE TEMP, will be indicated in the display by
a flashing warning triangle, and will be entered into the fault list.
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 from the beginning.
The source pump will always be 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 minutes after the heat
pump has been switched OFF.
Example for the setting 100 = 10 K
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 from the beginning.
The smaller the control deviation, the shorter the mixer ON time
and the longer its pauses.
A reduction of the MIXER DYNAMIC value with static control deviation increases the ON duration and reduces pauses.

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. Only in automatic
mode can the room temperature for heating circuit 1 or 2 be
adjusted by ± 5 °C. This set value adjustment applies to the then
current heating time, not to the setback time.
±1K
At the same time, 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. Afterwards, the system regulates in weather-compensated mode.

21
ROOM INFLUENCE
FE CORRECTION
This parameter enables the calibration of the actual room temperature.
Room temperature-dependent return/flow temperature with
weather compensation
With this type of control, a control cascade is formed from a return/flow temperature control that is subject to both weather and
room temperature. Consequently 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:
∆ϕR = (ϕRSET − ϕRACTUAL) * S * K
Because a substantial proportion of the control is already handled
by the weather-compensated control unit, the room temperature
sensor compensation factor K can be set lower than with pure
room temperature control (K = 20). The figure below 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 provides more stable control.
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 is the one which affects the entire heating circuit.
If you want the room temperature to be taken into account, set
the room temperature sensor influence to > 0.

13.1.5 The heat pump does not run
SENSOR BROKEN
26_03_01_1064
1
The heat pump is in standby mode [ ]
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.
Remedy: Change to automatic mode
The power supply has been blocked; the standby symbol flashes
[ ]
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:
Quick start:
Check the heat pump compressor by implementing a quick start

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.

13.3 Fault list parameter
Check and remove all faults in the fault list.
Fault display
Reason for fault code triggered by control unit:
HP sensor max
The fault will be written to the fault list and the system will be permanently shut
Controlled shutdown; down after the system has been shut down five times within the operating time (5
no fault
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.
LOW PRESSURE
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 will be written
to the fault list after it has occurred for the first time.
CONTACT STUCK
Each time the compressor is switched off, the system checks after ten seconds,
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.
HIGH PRESSURE
After the compressor has started, and after a delay of 15 seconds, masking checks,
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.
NO OUTPUT
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.
POWER-OFF
The power supply utility has blocked the heat pump (see chapter “Installation /
Troubleshooting / Fault indicators on the display / The heat pump is not running”).
Possible cause of fault/remedy
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").
MIN SRCE TEMP
The defined minimum source temperature was not reached.
Check the minimum, source temperature and change it
The fault is written to the fault list. The compressor starts again after the selected if required.
idle time has expired.
Check the source flow rate: Check source design.
MAX HOT GAS T
The compressor will be stopped for the minimum idle time if a hot gas temperature This requires no action, as it is a controlled shutdown.
Controlled shutdown; of 130 °C is exceeded. This is a normal controlled shutdown that is not entered into
no fault
the fault list. The reason for the shutdown is displayed for information during the
idle time.
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.
