Using the heat-up program
If you use the heat-up program, make the following settings on
the WPM:
Initially set the "DUAL MODE TEMP HZG" parameter to 30°C.
Then set the "LOWER APP LIMIT HZG" parameter to 30°C.
Note
After completing the heat-up process, reset the "DUAL
MODE TEMP HZG" and "LOWER APPLIMIT HZG" parame-
ters to their respective standard values or to the respec-
tive system values.
12.4 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 safekeeping.
All information in these instructions must be closely ob-
served. The instructions provide information on safety,
operation, installation and maintenance of the appliance.
13. Settings
13.1 Silent mode
SILENT MODE is an operating mode for air/water heat pumps in
which the sound level of the heat pump is reduced.
See the data table (see chapter “Specification/ Data table”)
for the sound power level when silent mode is deactivated.
You can reduce the fan speed and compressor output for a certain
time in the “COMMISSIONING/ SILENT MODE/ OUTPUTREDUC-
TION” menu.
Note
If you activate SILENT MODE, the maximum output at A-7/
W35 is reduced to 70% as standard.
This value can be increased further or reduced to the
specified minimum value as required.
Note
When silent mode is active, operating costs will be higher.
In silent mode 2, heating and DHW heating are provided
solely via the emergency/booster heater.
See the table for the maximum appliance sound levels ac-
cording to the settings made in the “COMMISSIONING/ SI-
LENT MODE/ OUTPUTREDUCTION/ OUTPUT” menu.

ating mode.
14. Appliance shutdown
!
Material losses
Never interrupt the heat pump power supply, even out-
side of the heating season. Otherwise, system frost pro-
tection is not guaranteed.
The heat pump manager automatically switches the heat
pump to summer or winter mode.
14.1 Standby mode
To shut the system down, 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 is completely switched off and there is a
risk of frost, drain the system on the water side.
15. Maintenance
WARNING Electrocution
Prior to commencing any service or cleaning work,
isolate the appliance across all poles from the
power supply.
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).
Check the condensate drain (visual inspection). Remove any con-
taminants and blockages immediately.
