Reset the high limit safety cut-out by pressing the reset but-
ton.

11.2.2 Heating curve adjustment
The efficiency of a heat pump decreases as the flow temperature
rises. Adjust the heating curve carefully. Heating curves that are
set too high cause the zone valves or thermostatic valves to close,
which may result in the minimum required flow rate in the heating
circuit being undershot.
Observe the WPM commissioning instructions.
The following steps will help you to adjust the heating curve cor-
rectly:
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 a remote control.
At different outside temperatures (e.g. -10°C and +10°C),
adjust the heating curve so that the required temperature is
set in the lead room.
Standard values to begin with:
Parameter Underfloor heating Radiator heating
system
Heating curve 0.4 0.8
Control dynamic 10 10
Comfort temperature 20°C 20°C
If the room temperature in spring and autumn is too low
(approx. 10°C outside temperature), raise the comfort tem-
perature.
Parameter
COMFORT TEMPERATURE (SETTINGS/ HEATING/ HEATING CIRCUIT)
Note
If no remote control is installed, raising the comfort tem-
perature 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
HEATING CURVE RISE (SETTINGS/ HEATING/ HEATING CIRCUIT)
If the heating curve has been raised, adjust the zone valve or
thermostatic valve in the lead room to the required tempera-
ture 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.
Once everything has been implemented correctly, the system
can be heated to its maximum operating temperature and
vented once again.

Material losses
For underfloor heating systems, observe the max-
imum permissible temperature for that particular
underfloor heating.
11.2.3 Other settings
For operation with or without a buffer cylinder, see chapter
"Menu/ SETTINGS/ STANDARD SETTING/ BUFFER OPERA-
TION" in the WPM commissioning instructions.
12. Appliance handover
Explain the appliance function to users and familiarise them with
how it works.
Note
Hand over these operating and installation instruc-
tions to the user for safe-keeping. All information in
these instructions must be closely observed. The in-
structions provide information on safety, operation,
installation and maintenance of the appliance.
