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 that the required temperature is
set in the lead room.
Standard values to begin with:

If the room temperature is not high enough in spring and autumn
(approx. 10 °C outside temperature), go to the heat pump manager
menu under "SETTINGS / HEATING / HEATING CIRCUIT" and raise
the "COMFORT TEMPERATURE" parameter.
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 when outside temper-
atures are low, increase the "HEATING CURVE" parameter.
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, 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.
!
Material losses
With underfloor heating systems, observe the maximum
permissible temperature for the system.

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.
If using the heat-up program
If you use the heat-up program, make the following settings on
the WPM:
f
f
Initially set the "DUAL MODE TEMP HZG" parameter to 30 °C.
f
f
Set the "LOWER APP LIMIT HZG" parameter to 30 °C.
Note
Following the heat-up process, return the "DUAL MODE
TEMP HZG" and "LOWER APP LIMIT HZG" parameters to
their default values or to the system values.
13. Shutdown
!
Material losses
Never interrupt the heat pump power supply, even out-
side the heating season. Otherwise, system frost protec-
tion is not guaranteed.
The heat pump manager automatically switches the heat
pump to summer or winter mode.
13.1 Standby mode
To shut down the appliance, simply set the heat pump manager
to "Standby mode". This way the safety functions that protect the
system remain enabled, e.g. frost protection.
13.2 Power interruption
If the system is to be isolated from the power supply permanently,
please observe the following:

If the heat pump and frost protection are completely
switched off, drain the system on the water side.
14. Maintenance
!
Material losses
Keep the air discharge and intake apertures free from
snow and ice.
f
f
Remove any leaves or other foreign bodies from the evapora-
tor fins periodically.
We recommend a regular inspection (to establish the current con-
dition of the system), and maintenance if required (to return the
system to its original condition).
