supply line. For this bear in mind that, depending
on the static pressure, you may also need a pressure reducing valve.
-- The safety valve discharge aperture must remain
open to the atmosphere.
-- Install the safety valve discharge pipe with a constant fall to the discharge outlet.
-- Size the discharge outlet so that water can drain
off unimpeded when the safety valve is fully
opened.
-- The WPC can be used for active and passive cooling. This however, is only possible in conjunction
with a suitable hydraulic circuit.
-- The WPC cool is only suitable for passive cooling.
Active cooling with the WPC cool will lead to appliance damage.
-- In the delivered condition, the COOLING parameter is set to OFF.
-- The COOLING parameter will only be shown if a
FEK or FE 7 remote control is connected. Cooling
mode is only possible in summer mode.
-- Maintenance work, such as checking the electrical safety, must only be carried out by a qualified
contractor.
-- We recommend regular inspection (to establish
the current condition of the system), and maintenance by a qualified contractor if required (to
return the system to its original condition).
-- Never interrupt the power supply, even outside
the heating period. The system’s active frost protection is not guaranteed if the power supply is
interrupted.

Appliance description
The appliance is a heating heat pump suitable for operation as a
brine/water heat pump. The heat pump extracts energy from the
heat source medium at a low temperature level. This extracted
energy is then transferred to the heating water at a higher level,
augmented by the electric energy drawn by the compressor. The
heating water is heated to a flow temperature of up to 65 °C,
depending on the heat source temperature.
A heating circuit pump and a multi function assembly (MFG) with
safety assembly and 3-way diverter valve have been integrated
in the appliance for directing the flow either to the heating circuit
or the DHW circuit. To heat the DHW, the heating water that has
been heated by the heat pump is directed through an indirect coil
in the DHW cylinder, where it transfers its energy to the DHW.
The appliance is equipped with an electric emergency/booster
heater (DHC). If the dual mode point can no longer be maintained
in mono mode operation, the electric emergency/booster heater
is activated to safeguard heating operation and the provision of
high DHW temperatures. In mono energetic operation the electric
emergency/booster heater is then activated as a booster heater.
The appliance is regulated by an integral, weather-compensated
return temperature controller (WPM3i heat pump manager).
The WPM3i also regulates the DHW heating to the required temperature. If either the high pressure sensor or the hot gas limiter
of the heat pump responds during DHW heating, then DHW heating
will automatically be completed by an integral electric emergency/
booster heater, subject to the DHW learning function being 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 further heat generator can be switched.

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.
Heat-up program for underfloor heating systems
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.
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.
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.

If a heating buffer cylinder has been integrated into the system,
the temperature in the buffer cylinder is controlled solely via the
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.

Adapting a heating curve
Example:
With heating systems, the temperature in a building during the
transitional periods (spring and autumn) is too low when outside
temperatures are between 5 °C and 15 °C, despite open radiator
valves, but is OK at outside temperatures ≤ 0 °C. This problem can
be remedied with a parallel shift and a simultaneous reduction
of the heating curve.
Heating curve 1.0 was initially 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 of 23.2 °C.

When using a buffer cylinder, set this parameter to ON.
 SUMMER MODE
Parameter SUMMER MODE enables you to define the point at
which the heating system is to switch to summer mode. Summer
mode can be switched on or off. There are 2 adjustable parameters
for this function.
 OUTSIDE TEMPERATURE:
Outside temperature adjustable from 10 °C to 30 °C
 BUILDING HEAT BUFFER
This parameter lets you choose whether an average outside temperature should be determined, according to the type of building.
You can choose from 3 settings.
Setting "1": Minor insulation towards outside temperatures (averaging over a 24 h period), e.g. for timber construction with rapid
heat transfer.
Setting "2": Moderate insulation towards outside temperatures
(averaging over a 48 h period), e.g. brick construction with thermal
insulation and average heat transfer.
Setting "3": Strong insulation towards outside temperatures (averaging over a 72 h period). House with slow heat transfer.
If the determined outside temperature is ≥ than the selected outside temperature, both heating circuits (if installed) enter summer
mode; reverse hysteresis –1 K.
With fixed-value control, summer mode is disabled for heating
circuit 1.
www.stiebel-eltron.com
If the temperature at the return sensor reaches this set value during heating operation, the heat pump is immediately switched
off. This safety function prevents the high pressure switch from
responding. No fault message is issued when this value is reached.
During DHW operation the return temperature is not scanned.
 MAXIMUM FLOW 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). When the program selector is set to standby and a
fixed temperature has been selected the frost protection is activated and the compressor is switched off. Summer logic remains
disabled with fixed temperature control. This means that the heating circuit pump is not switched off for the direct heating circuit.
 HEATING CIRCUIT OPTIMAL
When an Uponor DEM-WP module is connected, the heating curve
is dynamically optimised for the heat demand of individual rooms.
This involves modifying the preset heating curve by up to 50 %
of its original value.
The 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 PROTECT
To protect the heating system from frost, start the heating circuit
pumps at the selected frost protection temperature; the reverse
hysteresis is 1 K.

 HEATING CIRC PRESELECTION
The FE7 remote control can be selected for both heating circuits.
This parameter lets you choose which heating circuit the remote
control is to act on. Depending on the remote control preselection, the actual room temperature can be checked under INFO /
SYSTEM / ROOM TEMPERATURE.
-- The temperature inside the lead room affects the entire heating circuit.
If you want the room temperature to be taken into account, set the
room temperature sensor influence to a value > 0.
90
80
Standard setting 5 adjustable from ---- via 0 to 20 Dashes (----)
in the display:
With the FE7 remote control connected, the room temperature
sensor only serves to record and display the actual room temperature; it has no influence on the actual control. The remote control
can be used to adjust the room temperature for heating circuit 1
or 2 by ± 5 °C in automatic mode only. This set value adjustment
applies to the current heating time, not to the setback time.
At the same time, the setting "0 to 20" serves to control the room
temperature-dependent night setback. This means that the heating circuit pump is switched off at the point of changeover from the
heating into the setback phase. It remains off until the actual room
temperature falls below the set room temperature. After this, the
system continues to regulate in weather-compensated mode.
If you want the room temperature to be taken into account, set
the room temperature sensor influence to a value > 0. The room
sensor influence has the same effect as the outside temperature
sensor has on the return temperature, except that the effect is 1
to 20 times greater, depending on the factor set.
Room temperature-dependent return / flow temperature with
weather compensation
With this type of control, a control cascade is formed from both
weather-compensated and room temperature dependent return/
flow temperature control. This means that the weather-compensated return/flow temperature control sets a default return/flow
temperature that is corrected by the overriding room temperature
control in accordance with the following formula:

sensor compensation factor K can be set lower than with pure
room temperature control (K=20). The figure indicates the control
method with the set factor K=10 (room influence) and a heating
curve S=1.2.
The PUMP CYCLES parameter only applies to the direct heating
circuit 1, i.e. for heating circuit pump 1.
Room temperature control with weather-compensation
This type of control offers two main benefits:
Incorrectly set heating curves are corrected by the room sensor
influence K; whilst the smaller factor K means the control unit
works in a more stable manner.
However, observe the following for all control units with room
temperature sensor influence:
-- The room temperature sensor must capture the room temperature accurately.
-- Open doors and windows greatly affect the control result.
-- All radiator valves in the lead room must be fully open at all
times.
This parameter can be switched ON or OFF. In the OFF position,
the heating circuit pump will not cycle. It will operate constantly.
It is only switched off in summer mode.
As soon as you set the parameter to ON, the heating circuit pump
will be switched in line with a fixed temperature curve for the
outside temperature.
The heating circuit pump start pulse is always 5 minutes.
The heating circuit pump for heating circuit 1 always starts with
each heat pump start. The pump runs on for 5 minutes after the
heat pump has been shut down. This is where the start-up duration is brought to bear, e.g. at an outside temperature of 5 °C, the
pump starts 3 times per hour for 5 minutes respectively.

When heating DHW, the system automatically adjusts itself to the
required DHW temperature (self-learning function).
The electric emergency/booster heater will be added as a booster
stage as soon as the heat pump is shut down in DHW mode via
the HP sensor or via the hot gas temperature limit (130 °C). If the
flow temperature of 70 °C is achieved in this operating mode,
DHW heating will be terminated, and the set DHW temperature is
overwritten with the actual DHW temperature.
Setting ON
As soon as the heat pump is shut down in DHW mode via the HP
sensor or the hot gas temperature limit (130 °C), DHW heating is
terminated and the set DHW temperature will be overwritten with
the current actual DHW temperature. This operating mode saves
energy, as DHW is exclusively heated by heat pump.

Heat is extracted from the heating circuit and is passed to the
heat source system.
Stage 2 (source pump + compressor)
In addition, the refrigerant circuit extracts heat from the heating
circuit and transfers it to the heat source system.

OPERATION
Maintenance and care
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.

Maintenance and care
!
Material losses
Maintenance work, such as checking the electrical safety,
must only be carried out by a qualified contractor.
Cooling mode with the FE7
A damp cloth is sufficient for cleaning all plastic and sheet metal
parts. Never use abrasive or corrosive cleaning agents.
The FE7 remote control is not equipped with dew point monitoring. It can therefore only be used in conjunction with fan convectors with condensate drain. The cooling mode parameter must
be set to FAN.
We recommend regular inspection (to establish the current condition of the system), and maintenance by a qualified contractor
if required (to return the system to its original condition).

In the COOLING parameter, you can select the following cooling
modes for the FE7 and the FEK:
-- Room temperature
Cooling mode starts when the selected room temperature is
exceeded (output COOLING=230 V).
Cooling mode is stopped when the actual room temperature
drops 2 K below the set temperature. (output COOLING=0 V)
-- Flow temperature and hysteresis
Cooling mode is regulated via the selected flow temperature.
The brine pump starts at:
[Flow temperature + hysteresis]
Brine pump off when the actual temperature drops below the
flow temperature.
The [flow temperature+hysteresis] should be at least 3 K <
room temperature. Lower flow temperatures cause a more
rapid cooling of the room.
On the setting AREA COOLING, as soon as the determined
dew point temperature is + 2 K higher than the set flow temperature, that temperature will be overridden with the dew
point temperature and acts as control variable. The brine
pump starts at [entered or newly determined flow temperature + hysteresis].
If the actual flow temperature drops below the entered or
newly determined flow temperature, the source pump stops
and cooling mode is terminated. The cooling signal remains
active.
-- Dynamic
The Dynamic can be adjusted from 1 to 10. It describes the
delay and changeover between passive cooling and active
cooling, whereby active cooling is started sooner, the smaller
the value.

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

Appliance description
9.1
Mode of operation
The room in which the appliance is to be installed must meet the
following conditions:
-- No risk from frost.
-- The room must not be subject to a risk of explosions arising
from dust, gases or vapours.
-- When installing the appliance in a boiler room together with
other heating equipment, ensure that the operation of other
heating equipment will not be impaired.
-- The volume of the installation room should be at least
13.8 m³.
-- Load-bearing floor (for the weight of the unit, see chapter
"Specification / Data table").
ff
For installation on floating screeds, make provisions for a
quiet heat pump operation.
ff
Isolate the mounting surface around the heat pump by recesses. After completing the installation, seal these recesses
with a water-impervious and sound insulating material, such
as silicone for example.
The heat exchanger on the heat source side (evaporator) extracts
natural heat from the heat source. This extracted energy and the
energy drawn by the compressor drive is transferred to the heating
water by a heat exchanger on the heating water side (condenser).
Subject to the heat load, the heating water is heated up to + 65 °C.
The DHW is heated via the internal indirect coil inside the DHW
cylinder.
The electric emergency/booster heater starts if the high pressure
sensor or the hot gas limiter responds during DHW heating. In
addition it covers any residual heat demand, if the heating system
demand exceeds the heat pump output.
Special features of the WPC...cool
For cooling, the brine is pumped through a 3-way diverter valve
and a second heat exchanger, where the energy is extracted from
the heating water.

11.5.3 Connection and filling with brine
ff
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 charging unit
WPSF in the heat source inlet (see chapter "Accessories").
To facilitate the connection to the heat source system, elbow pushfit connectors are enclosed with the appliance (see chapter "Fitting
the push-fit connectors").
ff
Connect one flexible pressure hose each to act as an anti-vibration mount to the "heat source flow" and "heat source
return" connections. The pressure hoses are included as part
of the standard delivery.
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 depending on whether a ground
collector or a geothermal probe is used as the heat source.
For the mixing ratio see the table below.
26 | WPC | WPC coolwww.stiebel-eltron.com

Note
ff
Insulate the brine lines with diffusion-proof thermal

Checking the brine concentration:
ff
Determine the density of the ethylene glycol/water mixture,
e.g. with a hydrometer.
Using the actual density and temperature, you can check the actual
concentration in the diagram.
Note
The quoted performance data relates to ethylene glycol
(see "Specification").
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
Charge the system according to the following curve to prevent an unintentional response from the brine pressure
switch.

Material losses
High flow rates or water hammer can damage the appliance.
ff
Fill the appliance at a low flow rate.
In the delivered condition, the diverter valve of the MFG is positioned at the centre, enabling the heating and DHW circuits to be
filled evenly. If power is switched on, the diverter valve automatically moves into the central heating position.
If you intend filling or draining the system later, first place the
diverter valve into its centre position.
For this, activate controller parameter DRAIN HYD in the DIAGNOSIS / RELAY TEST SYSTEM menu.

2 Discharge outlet
ff
Size the discharge outlet so that water can drain off unimpeded when the safety valve is fully opened.
ff
Ensure that the safety valve drain is open to the outside.
ff
Install the safety valve drain with a constant fall to the discharge outlet. When installing the drain, never kink the pipe.
11.7 Oxygen diffusion
!
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.

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.
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.

11.11 DHW circulation connection
DHW circulation is not recommended for reasons of poor energy efficiency. If DHW circulation is required due to unfavourable
pipework or for reasons of convenience, you must install the DHW
circulation in accordance with applicable standards. To reduce
pump runtime and energy demand, we recommend imposing time
and temperature controls on activation of the circulation pump.
The DHW circulation connector is located at the back of the appliance (see chapter “Specification / Dimensions and connections”).
A circulation pump can be found in our range of accessories.

13.2 Heating curve adjustment during
commissioning
„COMMISSIONING
„
The efficiency of a heat pump decreases as the flow temperature
rises. Therefore adjust the heating curve with care. A heating
curve that is set too high leads to the zone or thermostatic valves
closing and the minimum flow rate required for the heating circuit
may not be achieved.
The following steps will help you to adjust the heating curve correctly:
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
achieved in the lead room.
Standard values to begin with:

Control dynamic
Comfort temperature

he a t ing
If the room temperature in spring and autumn is too low (outside
temperature approx. 10 °C ), the COMFORT TEMPERATURE parameter must be raised.
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 HEATING CURVE parameter has been raised, adjust the zone
valve or thermostatic valve in the lead room to the required temperature when outside temperatures are high.
Note
Never reduce the temperature in the entire building by
closing all zone or thermostatic valves, instead use the
setback programs.
Note
All menu points are protected by a code and can only be
viewed and adjusted by a qualified contractor.

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 consumer 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.

COMFORT MODE
If more than one fault occurs, the most recent fault is always
shown. Notify your qualified contractor.
16.2.1 Heat pump-specific or hardware faults
See chapter "Fault table".
16.2.2 The heat pump is not running
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.
Faults/errors in the system or in the heat pump are indicated on
the display. For heating system and heat pump troubleshooting
and analysis, all important process data and bus subscribers can
be called up under DIAGNOSIS and a relay test can be carried out.
ff
For troubleshooting, analyse all available parameters before
opening the heat pump control panel.
The power supply has been blocked, POWER-OFF is displayed.
ff
Wait for the blocking time to elapse. The heat pump will automatically start up again.
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.
There may be an incorrect fuse rating.
ff
See chapter "Specification / Data table".
There is no heat demand.
ff
Check the set and actual values under the INFO menu item.
Note
The heat pump can only be restarted after the fault has
been removed and the heat pump has been reset (heat
pump reset parameter).
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.
