11.1.6 High limit safety cut-out
In ambient temperatures of below -15 °C it is possible that the high
limit safety cut-out of the electrical emergency/booster heater
may trip.
Check whether the high limit safety cut-out has tripped.
Remove the cause of the fault.

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

11.2.1 Heating curve adjustment
The efficiency of a heat pump decreases with rising flow tempera-
ture. The heating curve should therefore be adjusted with care.
Heating curves that are adjusted too high lead to the zone and
thermostatic valves closing, which may lead to the minimum flow
rate required for the heating circuit not being achieved.
Observe the WPM 3 operating and installation 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 remote control.
- 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 for the start:
Parameter
Underfloor heating system
Heating system with radiators
Heating curve 0.4 0.8
CNTRL RESP TM 5 15
Room temperature 20 °C 20 °C
If the room temperature in spring and autumn is too low (approx.
10 °C outside temperature), the parameter “room temperature”
must be raised.
Note
If no remote control is installed, raising the parameter
“room temperature” leads to a parallel offset of the heat-
ing curve.
Increase the parameter “HTG CURVE” if the room temperature is
not high enough when outside temperatures are low.
If the parameter “HTG CURVE” has been raised, adjust the zone or
thermostatic valve in the lead room to the required temperature
at high outside temperatures.
!
Damage to the appliance and the environment
Never reduce the temperature in the entire building by
closing all zone or thermostatic valves, but by using the
setback programs.
When everything has been implemented correctly, the system
can be heated to its maximum operating temperature and vented
once again.
