Test symbols
See type plate on the appliance.
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,
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 65 °C.
The heating circuit pump, a multi function assembly (MFG) with
safety assembly and a three-way valve have been integrated in the
appliance for diverting the flow either to the heating circuit 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 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 such cases, the electric emergency/booster heater is activated in mono energetic operation 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 disabled. 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 other heat generator can be switched.

Special features of the WPF ... cool
Material losses
In cooling mode, condensate can form when the dew
point temperature is undershot.
ff
Take suitable measures to prevent the formation of
condensate.
An additional heat exchanger and three-way valve for changing
over between heating and cooling are integrated into the WPF...
cool.
The living space is cooled by the brine being pumped though the
additional heat exchanger, where the energy from the heating
water is extracted and passed to the cooler zones underground.
The compressor does not run during cooling.

Example:
You would like to heat DHW twice daily, i.e. 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; you have to begin programming at
00:00 h also for this example.
-- 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.
… PARTY PROGRAM
In the party program you can extend the comfort mode by a few
hours for heating.
… 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 00:00 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.
… HEAT-UP PROGRAM
Note
The HEAT-UP PROGRAM menu item is protected by a
code and can only be accessed and set by a qualified
contractor.
Heat-up program for underfloor heating systems
ff
Set the minimum source temperature to > 2 °C (see MIN
SOURCE TEMPERATURE parameter in the COMMISSIONING /
SOURCE menu).
ff
Set the temperature spread on the heat source side to < 3 K
via the flow rate (see BRINE PUMP RATE parameter in the
COMMISSIONING / SOURCE menu).
In some circumstances, screed drying may take longer than anticipated or may not be completed.
Screed drying with a geothermal collector:
If screed drying with a geothermal collector before the heating
season, screed drying must be completed by the end of August at
the latest. Otherwise the geothermal collector may not regenerate
in time for the heating season.
Settings
If you use the heat-up program, input the following settings at
the heat pump manager:
First set parameter “LOWER APP LIMIT HZG” to 30 °C.
There are a total of 6 parameters that serve to determine the temperatures and periods 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 the setting ON. Please note that depending on the
system temperature it may take some time to reach the required
low end temperature.
The low end temperature (parameter LOW END TEMPERATURE)
is held for the selected time (parameter DURATION BASE TEMP).
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.
Use the heat-up program to dry your screed with a defined temperature profile. To prevent damage to the appliance and/or the
installation, observe the following:
ff
Perform hydronic balancing of the underfloor heating
system.
ff
Open all lines of the underfloor heating system.
If screed drying with the heat pump, you will need to activate the
electric emergency/booster heater.
If screed drying with a brine/water heat pump, the heat source,
particularly a geothermal probe, may become overloaded. The
ground around the geothermal probe may freeze in the process.
Heat transfer to the ground will be irreparably damaged.
Screed drying with a geothermal probe:
If screed drying with a geothermal probe, obtain an approval from
the manufacturer of the geothermal probe.

The heating output required for the floor heating program may
exceed the design output of the heat pump. As a result, it may
not be possible to achieve the required flow temperature with the
heat pump. For problem-free heating/screed drying, therefore, we
recommend using an external mobile electric heating appliance.

return sensor (fitted at the base of the buffer cylinder). If only the
direct heating circuit 1 is operational, the set values are reduced
by 5 K to even out temperature differences in the buffer cylinder.
If 2 heating circuits are operational (second heating circuit is for
underfloor heating system), the mixer in heating circuit 2 regulates
down to the selected set values.
During the heat-up program the appliance often reaches maximum output. For this reason, energy consumption and noise levels
are comparatively high during screed drying.
After the heat-up process all modified parameters must be reset
to their standard values or system values.
Emergency operation is not possible while the heat-up program
is active.

Changing the set room temperature results in a parallel shift of
the heating curve.
The actual room temperature can also be scanned, 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 display HEAT CIRCUIT 2 only appears if the mixer flow sensor
for heating circuit 2 has been connected.MINIMUM TEMPERATURE
The set MINIMUM TEMPERATURE is safeguarded by the heating
circuit controller and will never be undershot.
 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.
 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.
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:
 HEATING CURVE RISE
The menu item HEATING CURVE RISE enables you to adjust 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. 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, 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
shows SET FIXED TEMPERATURE with the relevant temperature.
At the factory, heating curve 0.6 is set up for heating circuit 1 and

OPERATION
Menu structure
 BUILDING HEAT BUFFER
This parameter lets you choose whether an average outside temperature should be determined, according to the type of building.
You can select from 3 settings.
Setting "1": Minor insulation of the outside temperature (averaging
over a 24 h period), for example timber construction with rapid
heat transfer.
Setting "2": Moderate insulation of the outside temperature (averaging over a 48 h period), for example solid construction with
thermal insulation and average heat transfer.
Setting "3": Heavy insulation (averaging over a 72 h period) of the
outside temperature. House with slow heat transfer.
Both heating circuits (if installed) enter summer mode if the determined outside temperature is ≥ than the selected outside temperature; reverse hysteresis –1 K.
With fixed-value control, summer mode is disabled for heating
circuit 1.
 MAXIMUM RETURN TEMPERATURE
Setting range 20 °C to 60 °C.
The heat pump is switched OFF immediately if the temperature
at the return sensor reaches this value during heating operation.
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 TEMPERATURE
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.
 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). 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.
 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 initial value.
The HEATING CIRCUIT OPTIMAL parameter is only shown if no
mixer sensor and no 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 PROTECTION
To protect the heating system from frost, the heating circuit pumps
are started at the selected frost protection temperature; the reverse hysteresis is 1 K.
 REMOTE CONTROL FE7
This menu item is only displayed when the FE7 remote control is
connected.
 HEATING CIRCUIT PRESELECTION
Remote control FE7 can be selected for both heating circuits.
This parameter lets you choose on which heating circuit the remote control is to act. Depending on the remote control preselection, you can query the actual room temperature 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. 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.
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. 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 > 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 a return/flow temperature control that is subject to both weather and
room temperature. 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:
∆ϕR = (ϕRSOLL − ϕRIST) * 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

method with the set factor K=10 (room influence) and a heating
curve S=1.2.
Room temperature control with weather-compensation
The heating circuit pump start pulse is always 5 minutes.
This type of control offers two significant 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 affects the entire heating circuit.
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. Now the start-up duration takes
effect, for example at an outside temperature of 5 °C, the pump
starts 3 times per hour for 5 minutes each time.

Appliance and system damage
The WPF cool is only suitable for passive cooling. Active

however, is only possible in conjunction with a suitable
hydraulic circuit.
In the delivered condition, the COOLING parameter is set

!
Appliance and system damage
With the WPF ... S, cooling is not permitted.
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.

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.

The COOLING parameter will only be shown if an FEK or

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.
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.). Set parameter COOLING 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.
The following settings for the FE 7 and the FEK can be selected for
Cooling mode in parameter COOLING:
-- Room temperature
Cooling mode starts when the selected room temperature is
exceeded (output COOLING=230 V).
Cooling mode is stopped, if the actual room temperature
drops 2 K below its set temperature. (output COOLING=0 V)
-- 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.
As soon as, with setting AREA COOLING, 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 control variable. The brine
pump starts at [entered or newly determined flow temp. +
hysteresis].
The source pump stops and Cooling mode terminates, if the
actual flow temperature lies below the entered or newly
determined flow temperature. 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.
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.

Thoroughly flush the pipework before connecting the heat
pump to the heat source circuit. Foreign bodies, such as rust,
sand and sealant, can impair the operational reliability of the
heat pump. We recommend installing our Brine filling unit
WPSF in the heat source inlet (see chapter "Accessories").
To facilitate an easy connection to the brine circuit, the appliance
is supplied with plug-in connectors (see chapter “Fitting the pushfit connector”).
You can find the brine volume of the heat pump under operating
conditions in the data table (see chapter "Specification").
The overall volume equals that of the required amount of brine
that should be mixed from undiluted ethylene glycol and water.
The chloride content of the water must not exceed 300 ppm.

11.4 Installing the heat source system
Design the heat source system for the ground source heat pump
in accordance with the technical guides.
11.4.1 Permitted brine:
-- Heat transfer medium as concentrate on an ethylene glycol
base, part no: 231109 (10 l)
-- Heat transfer medium as concentrate on an ethylene glycol
base, part no: 161696 (30 l)
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.

Material losses
Do not use open vented heating systems. Use oxygen
diffusion-proof pipes in underfloor heating systems with
plastic pipework.
In underfloor heating systems with plastic pipes that are permeable to oxygen and in open vented heating systems, oxygen
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).
ff
With heating systems that are permeable to oxygen, separate
the heating system between the heating circuit and the buffer cylinder.

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

Fill the heating system via the drain. Refer to section “Determine the fill pressure”.
Determine the fill pressure
The diaphragm expansion vessel installed in the appliance has a
volume of 24 litres. The pre-charge pressure P0 is 1.5 bar.
If the height difference ∆h between the highest point of the heating system and the diaphragm expansion vessel is no more than
13 m, the diaphragm expansion vessel can be used without any
changes being required.
ff
Fill the heating system to a pressure of at least 1.8 bar
(P0 + 0.3 bar). Observe the safety valve’s response pressure
of 3 bar.
P0 =

D0000081230
If the height difference between the highest point of the heating
system and the diaphragm expansion vessel is more than 13 m,
the pre-charge pressure needs to be adapted.
ff
Calculate the pre-charge pressure:
For DHW heating, a DHW cylinder with internal indirect coils is
required. The minimum coil surface area required is 3 m³.
A three-way valve is integrated into the WPF between the DHW
heating circuit and the central heating circuit.
ff
Thoroughly flush the pipework before connecting the heat
pump. Foreign bodies, such as rust, sand and sealant, can
impair the operational reliability of the heat pump. We recommend installing our filter assembly in the DHW heating

must have a groove.
ff
Using a pipe cutter, cut a groove (depth approx. 0.1 mm) at a defined distance from the end of
the pipe.

How the push-fit connectors work
The push-fit connectors are equipped with a retainer with stainless steel serrations and an O-ring seal. In addition, the pushfit connectors are equipped with the “twist and lock” function.
Simply turning the screw cap by hand will secure the pipe in the
connector and push the O-ring against the pipe to seal it.
Making the push-fit connection
The connector must be in its relaxed position before the pipe is
inserted. In this position, there is a small gap between the screw
cap and main body.

Commissioning
13. Commissioning
Only qualified contractors may carry out the 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
13.1.1 Heating system
-- Have you filled the heating system to the correct pressure?
-- Have you closed the 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
!
13.1.5 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.
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 and thermostatic valves
closing and the minimum flow rate required for the heating circuit
may not be achieved.
Before commissioning check the points detailed below.
!
ff
Reset the high limit safety cut-out by pressing the reset
button.
Material losses
Never use the heat pump to dry the screed by means of
the underfloor heating system (see chapter „Menu structure / Menu PROGRAMS / HEAT-UP PROGRAM“).
The following steps will help you to adjust the heating curve correctly:
ff
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.
ff
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 the start:
Parameter
Heating curve
Control dynamic
Comfort temperature

hea t ing
If the room temperature in spring and autumn is too low (approx.

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.
ff
Check if the high limit safety cut-out has responded.
Note
If no remote control is installed, raising the COMFORT
TEMPERATURE 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 parameter HEATING CURVE has been raised, adjust the zone
valve or thermostatic valve in the lead room to the required temperature at high outside temperatures.
D0000036150
Note
Never reduce the temperature in the entire building by
closing all zone or thermostatic valves, but by using the
setback programs.

not scanned.
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.
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 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 seconds after the heat
pump has been shut down.
 BRINE PUMP RATING
The brine pump flow rate can be adjusted here.
The heat source flow rate is set via the temperature differential of

switch on the appliance using the parameter BRINE PUMP
RATING in the COMMISSIONING / SOURCE menu.
ff
Start the setting of the source pump after the heat pump has
run for at least 10 minutes.
The brine pump rating should be selected so that the temperature

 CONTROL 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 pre-selected dynamic should be sufficiently
fast and without oscillation. Heating systems that respond quickly
require a lower value, whilst very slow responding systems require the setting of a higher value.
 HP SENSOR MAX

ff
Heat pump type WPF MFG must be set.
 IDLE TIME
After a heat pump has been shut down, an idle time is set as
protection for 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 this parameter is started, OFF appears at the bottom of the display. Pressing PRG initiates
a quick start. The respective pumps are switched on after the heat
pump has started. The value 60 is visibly counted down to 0 on
the display; then the display shows ON.
After that, the heat pump and the associated buffer charging pump
are switched ON.
… EMERGENCY MODE
Characteristics in case of "Fatal Error" conditions in conjunction
with the emergency operation:
The EMERGENCY OPR parameter can be set to ON or OFF.
Emergency mode set to ON:
The program selector automatically changes over to emergency
mode as soon as faults occur and the heat pump fails.
Emergency operation set to OFF:
As soon as faults occur and the heat pump fails, the electric emergency/booster heater takes over the frost protection of the central
heating system. Users can then select emergency mode on their
own initiative.
… HEAT PUMP RESET
The heat pump can be reset if a fault occurs. Setting it to ON resets
the fault that has occurred. The compressor starts again. The fault
remains stored in the fault list.

Shutting down
15. Shutting down
16.2 Fault message
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).
If the appliance registers a fault, this is clearly displayed with the
message shown below.
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
Observe the temperature application limits and the minimum circulation volume on the heat utilisation side (see
chapter "Specification / Data table").
Material losses
If the heat pump and frost protection are completely
switched off, drain the system on the water side.
16. Troubleshooting
WARNING Electrocution
ff
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 queried under DIAGNOSIS and a relay test can be carried out.
ff
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.
ff
Check the heating flow rate and ventilate the heating system.

16.2.1 Heat pump-specific or hardware faults
See chapter "Fault table".
16.2.2 The heat pump does not run
The heat pump will not restart following a controller replacement
or after a “SYSTEM RESET” has been carried out:
Check the heat pump type in the controller menu DIAGNOSIS /
SYSTEM / HEAT PUMP TYPE. If this is not “WPC MFG”, execute
another “SYSTEM RESET” and select the correct heat pump type.
The heat pump is in standby mode [ ].
ff
Change the system over to programmed operation.
The power supply has been blocked, POWER-OFF is displayed.
ff
Wait until the blocking time elapses. The heat pump starts
again automatically.
There is no heat demand
ff
Check the set and actual values under the INFO menu item.
There may be an incorrect fuse rating.
ff
See chapter "Specification / Data table".
Note
The heat pump can only be restarted after the fault has
been removed and the heat pump has been reset (parameter HEAT PUMP RESET).
Additional parameters available for system analysis:
-- QUICK START: The quick start must only be carried out by our
customer support. The heat pump compressor is checked
during a quick start.
-- RELAY TEST: Test for all relays in the heat pump manager
