Operating mode
Note
If emergency mode is activated, higher operating costs
may result because of the booster heater.
Note
The heat pump has a start time of 5 to 10 minutes. The
start time does not apply to the “Emergency operation”
operating mode.
You can switch the heat pump to a different operating mode via
the appliance.
Symbol Operat-
ing mode
meaning
Standby
mode
The heat pump is not in operation. Frost
protection is active. The components in
the heat pump are live. If the primary
heat pump is switched off, the secondary
heat pumps are also switched off. If the
secondary heat pump is switched off, the
status is sent to the primary heat pump.
Restart
A restart is required after changes have
been made to certain parameters in the
menu. The heat pump can only be re-
started when it is in standby mode.
Service
mode
The heat pump is not in operation. Frost
protection is active. External functions
are in operation. The components in the
heat pump are live. If the primary heat
pump is switched off, the secondary
heat pumps continue to operate. If the
secondary heat pump is switched off, the
status is sent to the primary heat pump.
Emergency
operation
(only in
conjunction
with service
mode and
activated
booster
heater)
The heat pump is not in operation. Ex-
ternal functions are in operation. The
components in the heat pump are live.
The booster heater is only available for
