INSTALLATION
Shutdown
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.
13.4.2 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:
Initially set parameter "DUAL MODE TEMP HZG" to 30°C.
Then set parameter "LOWER APP LIMIT HZG" to 30°C.
Note
After completing the heat-up process, reset the parame-
ters "DUAL MODE TEMP HZG" and "LOWER APP LIMIT HZG"
to their respective standard values or to the respective
system values.
14. 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.
14.1 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.
14.2 Power interruption
If the system is to be isolated from the power supply permanently,
please observe the following:
!
Material losses
If the heat pump and frost protection are completely
switched off, drain the system on the water side.
15. Appliance handover
Explain the appliance function to users and familiarise them with
its operation.
Note
Hand over these operating and installation instructions
to users for safe-keeping.
Always carefully observe all information in these instruc-
tions. They provide information on safety, operation, in-
stallation and maintenance of the appliance.
