Starting up the heat pump
The start-up of your heat pump was carried out after
installation by your expert technician company.
Your heat pump does not need to be started up again if
it disconnects from the mains unexpectedly, for example
as a result of a voltage drop (power cut, circuit breaker
defective, circuit breaker deactivated). Your geoTHERM
heat pump has an automatic reset function, i.e. the heat
pump reverts automatically to its starting condition,
provided no fault is present in the heat pump itself. Find
out what to do in the event of a fault in Chap. 5.12.

Shutting down the heat pump
The heat pump can only be switched off via the opera-
tor control panel by deactivating the heating and hot
water generation (operating mode "Off").

5.9
In contrast to heaters based on fossil fuels, no expen-
sive maintenance work is necessary for the Vaillant geo-
THERM heat pump. However an annual inspection of the
system by a specialist is a prerequisite for continued
operational safety, reliability and a long working life.

• Read off the filling pressure of your heating installa-
The pressure in the heating installation should be be-
tween 1 and 2 bar. If it falls below 0.5 bar, the heat pump
will be shut down automatically and an error message
will be displayed.
Inspection by a specialist engineer
Danger!
If inspections are not carried out, this
can result in damage to property and
personal injury.
Only have inspections and repairs car-
ried out by an approved heating installa-
tion company.
Note Have your system checked regular-
ly by an expert technician company to
ensure efficient operation of your heat
pump.
