12.2 Initial start-up
12.2.1 Heating curve adjustment
The efficiency of a heat pump decreases as the flow temperature
rises. The heating curve should therefore be adjusted with care.
Heating curves that are set too high cause the zone valves and
thermostatic valves to close, which may lead to the minimum flow
rate required for the heating circuit not being achieved.
f
f
Observe the WPM 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 and 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 set in
the lead room.

If the room temperature is not high enough in spring and autumn
(approx. 10 °C outside temperature), raise the "COMFORT TEM-
PERATURE" parameter in the heat pump manager menu under
"SETTINGS / HEATING / HEATING CIRCUIT".
Note
If no remote control is installed, raising the "COMFORT
TEMPERATURE" parameter leads to a parallel offset of
the heating curve.
Increase the "HEATING CURVE" parameter, if the room tempera-
ture is not high enough when outside temperatures are low.
If you raise the "HEATING CURVE" parameter, adjust the zone valve
or thermostatic valve in the lead room to the required temperature
when outside temperatures are high.
!
Material losses
Never reduce the temperature in the entire building by
closing all zone or thermostatic valves, instead use the
setback programs.
When everything has been implemented correctly, the system
can be heated to its maximum operating temperature and vented
once again.
!
Material losses
With underfloor heating systems, observe the maximum
permissible temperature for the system.
12.2.2 Other settings

For operation with and without buffer cylinder, observe
chapter "Operation / Menu structure / Menu SETTINGS /
STANDARD SETTING / BUFFER OPERATION" in the operating
and installation instructions of the WPM.
When using the heat-up program
If you use the heat-up program, make the following settings on
the WPM:
f
f
Initially set parameter "DUAL MODE TEMP HZG" to 30 °C.
f
f
The set parameter "LOWER APP LIMIT HZG" to 30 °C.
Note
Following the heat-up process, return parameters "DUAL
MODE TEMP HZG" and "LOWER APP LIMIT HZG" to their
default values or to system values.
12.3 Operation and control
!
Material losses
Never interrupt the power supply, even outside the heat-
ing season. The system's active frost protection is not
guaranteed if the power supply is interrupted.
The system does not have to be switched off in summer. The
WPM 3 has an automatic summer/winter changeover.
