Information
OCHSNER customer service will provide an ex-
planation of the basic functions of the heat pump
system (controller operation, etc.). If the system
user is not present for commissioning, the system
installer will assume responsibility for this explana-
tion. Instruction on the functionality of the overall
system is the responsibility of the system installer.
11.7 Decommissioning
You do not need to switch off your heat pump system in
the summer. The heat pump control unit changes over au-
tomatically between summer and winter.
Material damage
If the power supply to your heat pump system is
switched off, frost protection of the system cannot
be guaranteed.
»
You should not switch off the power supply
to your heat pump, even outside the heating
period.
Should you wish to deactivate your heat pump system, then
switch off the system using the master controller. This way,
safety functions such as frost protection remain enabled.
Material damage
If the power supply to the heat pump system is
interrupted and there is a risk of frost, drain the
system on the water side.
