1.2 Equipment description
WPF is a heating system which is designed for
operation as brine/water heat pump. The heat
pump extracts energy from the heat source
medium i.e. brine at a low temperature level.
This extracted energy is then transferred to
the heating water at a higher level, enriched
with the energy transferred 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
or the DHW circuit. DHW is heated by pumping
the heating water, which has been heated by
the heat pump, through a heat exchanger into
the DHW cylinder, where it transfers its energy
to the DHW.
The equipment is regulated by an integral,
weather-compensated return temperature
controller (heat pump manager WPMiw (triple
phase) and WPMi (single phase).
The WPMi/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

Energy saving tip
zHeat 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).
zSize radiators so that the maximum required flow temperature does not exceed
45 °C.
zActivating the control parameter „Pump
cycling“ can reduce the power drawn by
the circulation pump. In this connection,
refer to your local heating contractor.
zWhen activating the „WW 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 to 60 °C at least once
every day, activate the „Pasteurisation“
parameter. In this connection, refer to your
local heating contractor.
1.3 Important Information
Only qualified contractors must install and maintain these heat pumps.
Vital facts in brief
Adjustments
All settings are made using similar steps:
Never:
z use process media which have not been
expressly authorised
z heat up other liquids than heating water
z install the equipment
a) outdoors
b) in areas which are at risk from frost
c) in wet areas, such as bathrooms
d) in areas which are at risk from dust
e) in areas which are at risk from explosions
z operate the equipment
a) outside the specified temperature limits
b) without a minimum circulating volume on the primary and secondary side
1.4 Operation
The operation is split over three levels. The
first and second operating levels are accessible
to users and contractors. The third level is only
accessible to contractors.
Operating level 1 (operating flap closed)
At this level, you can adjust the operating
mode, such as standby, automatic mode, constant day or setback mode, etc. (see section
1.8.1).
Operating level 2 (operating flap open)
At this level, you can adjust the menu items
like room temperatures, DHW temperatures,
heating programs, etc. (see section 1.8.2).
Operating level 3 (contractors only)
Access to this level is password-protected, and
should only be used by contractors. Here, heat
pump and system-specific details are determined (see section 2.11 and 2.13).
1.5 What to do if…
… there is no hot water or the heating system
stays cold:
Check the fuse/MCB in your fuse box. If the
MCB has tripped, reset it. Should it trip out
again, notify your local contractor.
With all other faults, notify your local contractor.
Opening the operating flap changes the
WPMi into the programming mode. An indicator arrow [symbol] appears at the bottom of the display at the menu item „room
temp. 1“.
Turning the selector [KNOPF] moves the
arrow to the menu item you wish to
change.
Press [PRG] to change the value of that
menu item. Whenever the red indicator
above [PRG] flashes, you can modify the
displayed value with the [KNOPF] selector. Press [PRG] again, and the indicator
extinguishes, and the new set value will be
saved. Further values for this menu item
can be modified by repeatedly pressing
[PRG], if the indicator above [PRG] does not
extinguish after saving the initially modified value. The programming phase can
only be terminated when the red indicator
has extinguished.
Terminating the programming phase
Only after entering and saving the required
modification of the menu item can the
phase be terminated by closing the control
flap. However, if you want to make further
modifications, turn [KNOPF] until the display shows BACK; then press [PRG]. This
will return you to the previous level. The
WPMi returns to its standard position if the
operating flap is closed whilst the red indicator above [PRG] is still illuminated. The
modified value will then not be saved.
A system check is implemented
during commissioning, i.e. all sensors currently connected are shown on
the display after the appropriate scan. The
WPMi will not register and consequently not
display those sensors that are not connected
when power is applied to the system. The
arrow indicator will skip that menu item.
1.6 Maintenance and care
Maintenance work, e.g. checking the
electrical safety, must only be carried out by qualified personnel. Protect the
equipment from dust and dirt ingress during
building work.
A damp cloth is sufficient for cleaning all plastic parts. Never use scouring or solvent-based
cleaning agents.
Risk of injury
Where children or persons with
limited physical, sensory or mental capabilities are to be allowed to control this
appliance, ensure that this will only happen
under supervision or after appropriate instructions by a person responsible for their
safety.
Children should be supervised to ensure
that they do not play with the appliance.
1.7 Operating and
installation instructions
Subject to the relevant system, observe the
operating and installation instructions of the
components of which the system comprises.
Keep these operating and installation
instructions safely and pass them
on to any new user, should the equipment
change hands, and let your contractor check
their content in conjunction with required
maintenance and repair work.

With the menu item ROOM TEMP 2 you can select the SET ROOM TEMP for day and setback mode
for heating circuit 2. ROOM TEMP 2 will only be displayed, if the mixer flow sensor for heating circuit 2 has been connected.
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.
DHW TEMP
You can allocate a set day or night temperature to the DHW cylinder temperature using the
menu item DHW TEMP
Time / Date
You can adjust the time and summer time with the TIME/DATE menu item.
At the factory, summer time is set up to begin on the 25 March and to end on the 25 October.
Hol / Party
The HOLIDAY PROG menu item puts the heat pump system into setback mode. Frost protection is
activated for the DHW cylinder.
The PARTY PROG menu item allows you to extend the day mode by a few hours.
Temperatures
The menu item INFO TEMP enables you to scan the heat pump or heat pump system sensor temperatures, comparing set with actual values, the heating curve gap, etc.
hTG cURVES
The HTG CURVE menu item enables you to adjust one heating curve each for heating circuit 1 and
2. The room temperature will only remain constant, irrespective of the outside temperature, if the
correct heating curve has been selected for the relevant type of building. Selecting the correct
heating curve is therefore vitally important.
hTG Prog
The HTG PROG menu item enables you to adjust associated heating programs for heating circuit 1
and 2 respectively.
dHw Prog
START UP
The DHW PROG menu item enables you to adjust the times for the day and setback temperatures
for DHW HTG.
As part of the commissioning process, determine not only the adjustments at control level 2 but
also the system-specific parameters. These parameters are adjusted at control level 3, access to
which is protected by code.
Check all parameters in sequence.
Enter all selected values into the column (system value) provided on the commissioning report.
1.8.3 In case of the WPF with WPAC 1, the room temperature for the cooling mode is set up by your contractor at control level 3. Cooling is activated,
when the room temperature is higher than the set room temperature. The cooling mode terminates, when the actual room temperature is 2 K < the
set room temperature.
For cooling via cooling surfaces (underfloor heating/wall area heating systems), you need the additional FEK remote control (part. no. 22 01
93). For cooling via fan convectors, you need the additional FEK remote control (part no. 22 01 93). Cooling via radiators would result in moisture damage; it is therefore not permissible.

Example:
During spring and autumn, the return or flow temperature of a heating system is too low at
an outside temperature between 5 and 15 °C, but is OK at outside temperatures of
≤ 0 °C. This problem can be remedied with parallel offset and a simultaneous reduction of the
heating curve.
Prior to this adjustment, heating curve 1.0 was adjusted, relative to a Set room temperature
of 20 °C. The dotted line indicates the modified heating curve at 0.83 and a modified set room

Heating programs
Htg Curve
The HTG PROG menu item enables you to adjust associated heating programs for heating
circuit 1 and 2 respectively.
You can adjust your heating system as follows:
–
for each individual day of the week
(Monday, ..., Sunday)
–
Monday to Friday (MON - FRI)
–
Saturday and Sunday (SAT - SUN)
–
the whole week (MON - SUN)
You can adjust three switching time pairs
(I, II, III) for each of these options.
This determines, when and how often the heat
pump system should heat in day mode. At all
other times, the heat pump operates in setback mode. You will already have selected the
corresponding set values for day and setback
mode under menu item
ROOM TEMP 1/2.
Example: For heating circuit 1, your heating
system should operate daily from Monday to
Friday at two different times, i.e. from 05:30
h until 08:30 h as well as from 14:00 h until
22:00 h. For the weekend, your heating system
should provide heat from 08:30 h until
21:00 h.

The DHW PROG menu item enables you to adjust the times for the day and night temperatures for DHW heating.
You can adjust your DHW heating as follows:
–
for each individual day of the week
(Monday, ..., Sunday)
–
Monday to Friday (MON - FRI)
–
Saturday and Sunday (SAT - SUN)
–
the whole week (MON - SUN)
You can adjust three switching time pairs (I, II,
III) for each of these options.
Exception:
You will need two switching time pairs, if you
want to heat DHW from 22:00 h until 06:00 h
the following day. This determines, when and
how often the heat pump system should heat/
load DHW in day mode. You will already have
selected the corresponding set values for day
and setback mode under the DHW TEMP system parameter.
Example:
You want to heat up DHW daily at two different
times, i.e. from 22:00 h until 06:00 h the following day, and then again from 08:00 h until

2.5 Operation and control
2.8 Regulations and requirements
~
The WPMi heat pump manager integrated into
WPF controls the entire heating system. All
necessary adjustments prior and during operation are made on this device.
On the water side:
DIN 4751 Bl. 1 and 2: Safety equipment for hot
water heating systems
~
Only qualified contractors must make adjustments listed in the commissioning report of
the heat pump manager.
Generally, the system must not be
shut down during summer, as the
WPMi is provided with an automatic summer/winter changeover facility. Set the
WPMi to standby when the system is taken
out of use. This retains the safety functions
designed to protect the system
(e.g. frost protection).
Drain the water side of the system, if the heat
pump installation room is subject to a risk
from frost.
The water inside the condenser can be
drained via the fill & drain valves, which are
accessible after removing the front cover.
DIN 1988: Technical rules for DHW installations
TRD 721: Safety equipment to prevent excess
pressure - safety valves.
On the electrical side:
DIN VDE 0100: Regulations for the installation
of HV systems with rated voltages up to
1000 V.
VDE 0701: Regulations regarding the repair,
modification and testing of used electrical
equipment.
DIN-EN 60335 part 2-40
TAB: Technical connection conditions for connections to the LV mains.
On the refrigerant side:
EN 378: Safety and environmental requirements.
Pressure Equipment Directive
2.6 Maintenance and cleaning
2.6.1 Maintenance
The heat pump operates under automatic
control and requires no specific maintenance.
If heat meters are installed, frequently clean
their strainers, which block easily.
2.6.2 Cleaning
Condenser
When the heat pump operation is impaired
(HP limiter trips) through deposits of corrosion
byproducts (rust sludge) inside the condenser,
only dissolving them by means of solvents
used by our customer service will remove this
problem.
2.7 Equipment description
2.7.1 Function
The heat source medium enters the heat
pump evaporator. There, heat is extracted
from the medium, so it exits the heat pump at
a lower temperature.
The energy made useful through the heat
pump is transfered to the heating water inside
the condenser.
Then, the heating water transfers its energy to
the heating circuit or is utilised for heating the
DHW. In that case, the heating water is diverted by a three-way valve to a heat exchanger
(indirect coil) inside the DHW.
The electric booster heater (internal HS 2)
starts, when the high pressure sensor or hot
gas limiter respond during DHW heating.
In addition, it can cover the residual heat
demand, when the heating system heat
demand exceeds the heat pump output.
20
General:
Collation of technical requirements for boiler
rooms, e.g. Boiler Room Directives or national/local Building Regulations, commercial and
fire as well as emission control regulations
and requirements.
TA-Lärm: Technical instructions to protect
against noise emissions.
2.9 Installation
2.9.1 Transport
To protect the equipment against damage,
it must be transported vertically inside its
dedicated packaging. Storage and transport
at temperatures below -20 °C and in excess of
+50 °C are not permissible.
2.9.2 Installation
The heat pump is designed for
installation in interiors, except in wet
areas.
1.
2.
Remove the equipment from its pallet
and position it where required.
Remove the eight screws from the
equipment plinth (Fig. 3), and set down
the casing onto the floor.
The casing must stand on the floor
free from the refrigeration unit. That
means, the eight plinth screws must not be
refitted.
Checking the condition at the installation location
The room where the WPF should be installed
must meet the following conditions:

FWT]X]bcP[[X]VcWTF?5X]PQ^X[Ta
room together with other heating equipment ensure, that the operation of other
heating equipment will not be impaired.
2.9.3 Installation of heat source system for
WPF with brine as heat source
Design the heat source system for the brine
water heat pump in accordance with
Stiebel Eltron technical guides.
Permitted brine:
–
Ethylene glycol
–
Propylene glycol
–
Concentrated process medium
Part no: 161696
–
Ready-mixed process medium
Part no: 185472
When using ready-mixed process medium
(part no. 185472), never seal the heat source
system with hemp.
2.9.3.1 Circulation pump and required volume
flow
Use a circulation pump with compound-filled
windings to supply the brine, to prevent an
earth short circuit through condensation in the
electrical part of the pump (cold water version). Size the circulation pump in accordance
with the system-specific conditions, i.e. observe the rated volume flow and pressure drop
(see specification).
Sufficient volume flow must be safeguarded at
every possible brine temperature, i.e.
–
rated volume flow at a brine temperature of 0 °C with a tolerance of +10 %.

2.9.3.2 Connection and filling with brine
Prior to connecting the heat pump, check the
heat source circuit for possible leaks, and flush
thoroughly.
After filling the system with brine, and prior
to commissioning, open the fill & drain valve
(item 17, Fig. 1), until brine runs out of it. No
water must remain in the pipe run to the fill &
drain valve.
Calculate the volume of the heat source circuit.
You can obtain the brine volume inside the
heat pump from the following table.

2.9.3.3 Volume flow control
(to be implemented during heat pump commissioning)
Measure the flow and return temperatures
of the heat source. For this, determine the
temperature difference by measuring the
temperature under the thermal insulation on
both flow and return pipes of the heat pump.
The diagram (Fig. 8) shows the temperature
spread at the rated volume flow.
You can check the source inlet temperature on the WPMi display under
system parameter INFO TEMP.
2.9.4 Installation of the heat utilisation
system
2.9.4.1 Heating circuit
The heat utilisation system must be installed
in line with current technical guidelines. For
safety equipment on the heating system, consult DIN 4751 page 2 or local regulations.
Prior to connecting the heat pump, check the
heating system for leaks, flush it thoroughly,
fill and carefully vent it.
When filling the heating system with heating
water, observe VDI 2035, sheet 1 [or local
regulations]. Particularly ensure that
z during the service life of the system, the
total fill and top-up water must not exceed
three times the nominal content of the
heating system,
z the total alkaline earths in the water must
be < 3.0 mol/m³,
z the total water hardness must be < 3
mmol/l
z the water must be softened, if the above
requirements are not met.
Generally soften the heating water if the specific system content is > 20 l/kW output (e.g. in
case of system with buffer cylinder).“
Check the correct connection of heating flow
and return (Fig. 5). The reduction of structureborne vibrations on the water side requires
the installation of flexible pressure hoses (for
part no. see section 2.3).
Implement thermal insulation in accordance
with local regulations.
2.9.4.2 Buffer cylinder
A buffer cylinder is recommended to ensure
trouble-free heat pump operation. The buffer
cylinder provides hydraulic separation of the
volume flow in the heat pump circuit and the
heating circuit.
The volume flow in the heat pump circuit
remains constant if, for example, the volume
flow in the heating circuit is reduced by thermostatic valves.
2.9.4.3 Circulation pump (cylinder loading
pump)
The cylinder loading pump is integrated into
the WPF. Consider the available external head
of 2.8 m when sizing the anti-vibration elements 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 are sized so that
the total pressure drop outside the heat pump
is less than the available external head of 2.8
m.
2.9.4.4 Circulation pump (central heating
pump)
If no cylinder (buffer cylinder) is used, consider the maximum external pressure of
280 hPa when sizing the heating circuit.
Ensure the rated volume flow of the heat
pump under all operating conditions of the
heating system by installing an overflow valve.
2.9.4.5 Heat meter
Observe the additional pressure drop when
installing heat meters on the heating side. The
sives inside the heat meters are easily blocked
by the dirt particles in the heating circuit, further increasing the pressure drop.
The WPF must be able to be separated from
the mains power supply by an additional isolator, which disconnects all poles with at least
3 mm contact separation. For this purpose,
use contactors, mains isolators, fuses, etc. on
site.
2.9.4.6 Oxygen diffusion
Corrosion can affect steel components, when
non-impermeable plastic underfloor heating
system pipes are used with steel radiators,
steel pipes or DHW cylinders.
Terminals are located inside the WPF control
panel (Fig. 9 and 10). The terminals become
accessible by removing the front cover
(Fig. 3) and opening the front panel. To open
the front panel, remove the fixing screws on
the side at the top of the control panel. When
removing the front cover ensure, that the cables, which connect the heat pump manager
with the control panel, are not torn off.
Remove the lid to enable the equipment to be
connected (Fig. 3).
Assemble these components in reverse order.
For this, observe the following:
–
After closing the front panel, tightly secure this to the control panel using the
fixing screws and serrated washers.
–
When fitting the front cover secure it,
as shown in Fig. 4, to the side panels
(screws and serrated washers included
in the pack supplied).
–
Route all connecting cables and sensor
leads through the apertures in the back
panel (item 7, Fig. 5).
The product of corrosion, i.e. rusty sludge, can
settle inside the heat pump evaporator and
can result in output loss through a reduction
of cross-section or in a heat pump shutdown
triggered by the high pressure limiter.
Therefore, never use heat pumps type WPF in
conjunction with underfloor heating systems
with non-impermeable pipes.
2.9.4.7 Scaling
Water quality, operating conditions and the
water volume are decisive factors to the extent
of scaling. To prevent damage to valves, heat
exchanger and heating elements, check the
water condition and assess it in accordance
with VDI 2035 [or local regulations].
Note: An awareness of hardness in
accordance with the Detergent Act [Germany]
is insufficient. Decisive for scaling is the
concentration of calcium hydrogen carbonate,
which can be supplied by your water supply
company.
2.9.4.8 DHW heating
For DHW heating, a DHW cylinder with internal indirect coils is recommended (see special
accessories).
A three-way diverter valve is integrated into
the WPF between the DHW heating circuit and
the central heating circuit. Connect the upper
coil connection of the DHW cylinder to the
DHW flow of the WPF (see Fig. 5).
The compressor must only turn in
one direction. Should the WPMi
display indicate the fault No power during
start-up, interchange the cores of two phases to change the rotational direction.
After connecting all electrical cables, refit and
seal the cover over the mains terminal strip
(X3) (Fig. 9 and 10).
Terminal rating of the electrical supplementary heater
Mark the box in front to the relevant terminal
rating on the label below the type plate.
Connect the lower coil connection of the DHW
cylinder to the WPF return. For this, insert a
tee immediately behind the anti-vibration joint
connected directly to the WPF. With this tee,
join the central heating and the DHW heating
circuits.
2.10 Power supply
Notify your local power supply company of the
electrical connection.
Only qualified electricians must carry out the
installation in accordance with these instructions.
Before any work, isolate the equipment from the power supply at the
control panel
Observe VDE 0100 and the regulations of your
local power supply company.
23
Sensor installation
The temperature sensors have a decisive influence on the function of your heating system.
Therefore ensure the correct seating and adequate insulation of sensors.
Outside temperature sensor AFS 2
(included in the pack supplied)
PTC sensor resistance values
The sensors installed in the WPF (return, flow
and source sensors), the outside temperature
sensor AFS 2, the contact sensor AVF 6 and the
PTC immersion sensor TF 6A all have identical
resistance values.

wall.
Minimum distances:
2.5 m above the ground
1 m away from windows
and doors.
The outside temperature sensor should be
freely exposed to the elements, but should not
be installed above windows, doors or air ducts
and should not be subject to direct sunlight.
Connect the outside temperature sensor to terminal X2/9(T (A)) and the earth terminal block
X26 of the WPF.
Installation:
Pull off the lid.
Secure the lower part with the screw supplied.
Insert and connect the sensor lead. Re-position the lid and let it audiby click into place.

2.13 Commissioning in detail
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.
Check all parameters in sequence. Enter all
set values into the column (system value) of
the commissioning checklist in section 2.15 on
page 40.
Note: Not all adjustments take immediate
effect. Some adjustments only become
effective in certain situations or after a delay.
COOLING MODE
WPF 5 - 16
This equipment is designed for DHW and
central heating. In the delivered condition,
parameter 6 is set to OFF. The cooling mode
is only possible with the WPAC-1 cooling
module.
On a WPF 5-13 without cooling
module, this parameter must not be
enabled.

CODE 1 0 0 0
Enter the correct four-digit code to change
parameters at control level 3. The factory-set
code is 1 0 0 0.
After pressing the PRG key (indicator
illuminates), the first digit can be selected by
turning the rotary selector. Pressing the PRG
key again confirms the value, then the second
digit of the code begins to flash. Turning the
rotary selector enables the second digit to
be entered. 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. Settings can be checked
without entering the code.

EMERGENCY MODE
Characteristics in case of Fatal Error conditions
in conjunction with the emergency operation:
The "Emergency mode" parameter can be set
to ON or OFF.
Emergency mode set ON:
The program selector automatically changes
over to emergency operation as soon as faults
occur and the heat pump fails.
Emergency mode set OFF:
The backup heat source takes over the frost
protection of the central heating system, as
soon as faults occur and the heat pump fails.
Users can then themselves select emergency
operation.

6
Set this parameter to ENABLE.
Note: This parameter will only be shown,
if a FEK or FE 7 remote control unit is
connected. The cooling mode is only
possible in summer.
The WPF with the WPAC 1 cools in
2 stages:
Stage 1 (source pump)
Heat is extracted from the heating circuit and
is transferred 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 return 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 FE 7 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 unit 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 set flow temperature is compared with the
detected dew point temperature, so the actual
temperature never drops below the dew point.
When using fan convectors with the FEK
remote control, set parameter 6 to FAN.
The following settings for the FE 7 and
the FEK can be selected for the cooling
mode in parameter 6:
- Room temp
Cooling starts, when the selected room
temperature is exceeded
(output COOLING=230V).
Cooling is stopped, if the actual room
temperature drops 2 K below its set
temperature. (output COOLING=0V)
- Flow temperature and hysteresis
The 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, the
determined dew point temperature
+ 2 K is 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 is stopped and the
cooling mode is terminated, if the actual
flow temperature lies below the entered
or newly determined flow temperature.
The cooling signal remains active.
- Dynamics:
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.
8
HEAT UP PROG
Heat-up program for underfloor heating
systems
This heat-up program comprises a total of
six parameters. These six parameters can be
adjusted in sequence as soon as the heat-up
program is activated. This program is started
with the parameter heat-up prog and with
the setting ON. The system then heats to the
selected low end temperature (parameter
LOW END TEMP). The low end temperature
is then held for the set period (parameter
low end durat). After expiry of this period,
the system heats with an increase K/day
(parameter increase/day) to the maximum
low end temperature (parameter Max heat-up
temp) and held at the maximum temperature
via the selected time (parameter Max temp
time). After expiry of this period, the system
reduces the temperature back to the low end
temperature in the same stages as per heatup. 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). The direct heating
circuit 1 (buffer circuit with return sensor)
adopts the heat-up program set values. The
actual temperature inside the buffer cylinder
is higher at the heating flow as the regulation
takes place 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).
Please note that only the mixer circuit pump
is running when operating with two heating
circuits.
The return sensor is again used for control,
when only the direct heating circuit 1 is
operational. As the actual temperature
inside the buffer cylinder is higher at the
heating flow, this constellation sees 5 K being
deducted from the heat-up program set values
(low end and maximum temperatures).
The summer logic is disabled when the heatup program runs.
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. In total, this
function offers two adjustable parameters.
The "Building Type" parameter determines,
subject to building type (setting 1, 2 or 3), an
adjusted outside temperature. Both heating
circuits (if installed) enter summer mode, if
the adjusted outside temperature is ≥ than the
selected outside temperature; reverse hysteresis –1 K.
The display indicates summer mode when the
flap is closed.
Summer mode is disabled for heating circuit 1
when regulating to a fixed temperature.
OUTSIDE TEMP parameter:
Available outside temperature 10 °C to 30 °C
Building type parameter:
Setting 1: Mild adjustment (averaging over a
24 h period) of the outside temperature, e.g.
timber construction with rapid heat transfer.
Setting 2: Average adjustment (averaging over
a 48 h period) of the outside temperature, e.g.
solid construction with thermal insulation and
average heat transfer.
Setting 3: Severe adjustment (averaging over
a 72 h period) of the outside temperature, e.g.
house with slow heat transfer.

Pump kick
To prevent the pump from seizing up, for
example during summer, 24 hours after the
pump was last switched OFF, it will be started
for 10 s. This applies to all pumps.
PUMP CYCLES
9
Heating circuit pump control
The PUMP CYCLES parameter only applies to
the direct heating circuit 1, i.e. for heating
circuit pump 1.
The parameter can be set to ON or OFF. In
setting OFF, the heating circuit pump will not
cycle. It will run permanently and only be
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
5 minutes.The heating circuit pump for HC 1
always begins 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 5
minutes respectively.
Heating circuit pump control with connected
FE 7/FEK remote control unit
In conjunction with the FE 7 of FEK remote
control unit, the respective heating circuit
pump is switched OFF and the mixer moves
to "Closed" in accordance with the switching
condition:
-ACTUAL room >-SET room + 1K
This only applies if the room sensor influence
is set to K > 0. Reverse control is subject to the
following condition:
-ACTUAL room <-SET room
The summer mode also becomes effective for
the respective heating circuit when operating
with a FE 7 or FEK remote control unit.
< -10 °C

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

Never operate the equipment
with source temperatures below
- 9 °C (triple phase) - 5 °C (single phase)
With setting OFF, the source sensor
temperature will not be 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 SRCE TEMP, will be
indicated in the display by a flashing warning
triangle, and will be 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.
The source pump runs on for 60 seconds after the heat pump has been
switched OFF.
14
RTRN MAX
Maximum return temperature
Setting range 20 °C to 55 °C.
The heat pump will be switched OFF
immediately, when the temperature at the
return sensor reaches this value during
heating operation. This safety function
prevents the high pressure limiter from
responding. Reaching this value will
not trigger a fault message. The return
temperature is not scanned during DHW
operation.
15
MAX FLOW T HTG
Maximum heat pump flow temperature for
central heating
Setting range 20 °C to 65 °C.
This setting limits the heat pump flow
temperature and all secondary heat sources
during heating operation.
16
MIXER MAX
19
Maximum mixer flow 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 is used by the controller, which
regulates to this value.
18
MIXER DYNAMIC
Mixer runtime
Setting range 60 to 240
This setting enables a matching of the mixer
to the control characteristics. Setting 60 to 240
means 6 K to 24 K control deviation.
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.
Example for the setting 100 = 10 K (see Fig.
below).
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.
FROST PROTECT
To prevent the heating system freezing up,
the heating circuit pumps are started at the
selected frost protection temperature; the
reverse hysteresis is 1 K.
20
PRESET REM CON
The FE 7 remote control can be selected for
both heating circuits
Using the SELECT REM CON parameter, you
can predetermine for which heating circuit
the remote control should be active. Under
the parameter ROOM T 1 OR 2 at control level
2, you can scan the actual room temperature,
subject to the remote control preselection.
21
FE CORRECTION
This parameter enables the calibration of the
actual room temperature.
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.
In other words, the smaller the control
deviation, the shorter the mixer ON time and
the longer its pauses.
A reduction of the MIXER DYNA TM value
with static control deviation increases the ON
duration and reduces pauses.

ROOM INFLUENCE
Room influence for the FE 7 remote control unit
Standard setting 5 adjustable from ----via
0 to 20
Dashes (----) in the display:
With the FE 7 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 for the then
current heating time, not for the setback time.
At the same time, setting "0 to 20" serves to
control the room temperature-dependent
night setback. This means, 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.
If you want the room temperature to be taken
into account, set the room temperature sensor
influence to !. The room sensor influence
has the same effect as the outside temperature
sensor has on the return temperature. Only
this effect is 1 to 20 times greater by the set
factor.
Room temperature-dependent return
temperature with weather compensation
With this type of control, a control cascade is
formed from weather-compensated and room
temperature-dependent return temperature
control. In other words, the weathercompensated return temperature control
pre-selects the return temperature, which is
corrected by the overlaid return temperature
control in accordance with the following
formula:
Because a substantial proportion of control
is already taken care of by the weathercompensated control unit, the room
temperature sensor influence K can be set
lower than with a purely 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.
24
Dual-mode temperature of the heat pump for
heating operation
Below this outside temperature, the backup
heating is added for central heating, subject
to load.
25
Room temperature control with weathercompensation
This type of control offers two substantial
benefits:
Incorrectly set heating curves are corrected
by the room temperature sensor influence
K, whilst the smaller factor K provides more
stable control.
DHW LIMIT
Operational heat pump limit
The heat pump is switched OFF at outside
temperatures below the selected lower DHW
limit.
Only the backup heating system provides DHW
heating.
26
However, observe the following for all control
units with room temperature sensor influence:
DUAL-MODE DHW
Dual-mode temperature of the heat pump for
DHW operation
Below this outside temperature, the backup
heating is added for DHW heating, subject to
load.
–
The room temperature sensor must
capture the room temperature accurately.
– Open doors and windows severely
influence the control result.
– All radiator valves in the lead room must
always be fully open.
– The temperature inside the lead room is
decisive for the entire heating circuit.
Set the room temperature sensor influence to
> 0, if you want the room temperature to be
taken into account.
27
DHW ECO
DHW learning function
Setting OFF
When heating DHW, the system automatically
adjusts itself to the required DHW temperature
(self-learning function).
The backup heating system will be added as
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). The DHW heating will be terminated,
and the set DHW temperature is overwritten
with the actual DHW temperature, 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 via the hot gas temperature limit
(130 °C). This operating mode saves energy,
as the DHW is exclusively heated with the heat
pump.
28
DHW HYSTERESIS
This determines the switching hysteresis for
the DHW operation.
– Starting DHW heating at the DHW set
value minus the hysteresis value.
29
DHW CORRECTION
The DHW temperature is measured in the
lower third of the cylinder. The DHW outlet
temperature is approx. 3 K higher than the
measured temperature. This deviation is
corrected and can be calibrated, if required.
30
PASTEURISATION
The DHW cylinder is heated daily at 01:00 h to

31
CNTRL DYNAMIC
Setting range 0 to 30
The selected control dynamic is a measure
of the switching gap between individual
compressors and the backup heating stages.
Normally, the selected response time
should operate sufficiently fast and without
oscillation.
Heating systems which respond quickly
require a lower value, whilst very slow
reacting systems require you to set a higher
value.
32
COMPRESSOR IDLE TIME
After a heat pump has been switched OFF,
an idle time is set as compressor protection.
The default idle time of 20 minutes should
generally 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.
33

Pressing PRG initiates a quick start. The
respective pumps are started after the heat
pump start. 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 primary pump are switched ON.
You terminate this function by pressing PRG
or by closing the control flap. OFF is displayed
again.

Fig. 1, page 14) can be reset by your heating
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 volume flow.

All faults cause the heat pump to shut down.
The idle time is set and, with the exception of
"HOT GAS MAX" all faults are written to the
fault list.

2.14.2 Fault display:
Sensor break = sensorfault
The heat pump is in standby mode [ ]
Remedy: Change to automatic mode
SENSOR BROKEN
This fault code refers to temperature
sensors which can be called up
under the system menu item "Info Temp".
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.
Observe the list under system parameter
"Info Temp" (see page 9).
The power supply has been blocked; the
standby symbol flashes [ ]
Remedy: Wait. The heat pump starts again
automatically after the power-off
time has expired.

Fault description:
Remedy
High pressure
sensor max
Controlled
shutdown.No fault.
The fault will be written to the fault list and the system will be
permanently shut down after the system has been shut down five times
within the operating time (5 minutes). Generally, the shutdown via
the HP sensor max. is a controlled shutdown that is only displayed for
information and for the duration of the idle time, i.e. it is not entered
into the fault list. Only frequent shutdowns over a short period of time
point towards a fault and are therefore entered into the fault list.
Only when a fault has been entered into the fault
list: Check the flow temperature monitoring and
the HP sensor.
Check the volume flow and temperature on the
heating side.
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.
Check the volume flow and the layout of the
source side.
Check the refrigerant level (sight glass).
Contactor stuck
Each time the compressor is switched OFF, the system checks after 10
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.
Check contactors K1 and K2 and replace, if
required.
High pressure
After the compressor has started, and after a delay of 15 seconds,
masking checks, whether the relay K9 is open. An 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.
Monitor the flow temperature and check the high
pressure sensor.
Check the volume flow and the temperature on the
heating side.
No power
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. The
system is then permanently shut down.
Compressor turns in the wrong direction.
Change the rotational direction by interchanging
two supply cores
Source min.
The defined minimum source temperature was not reached. The fault is
written to the fault list.
The compressor starts again after the selected idle time has expired.
Check the minimum source temperature and
change it, if required.
Check the source volume flow. Check the source
layout.
The compressor will be stopped for the minimum idle time if a hot gas

This requires no action, as it is a controlled
shutdown
2.15 Commissioning report
The controller 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.
