Carrying Out The Initial Commissioning - Vaillant geoTHERM VWS Installation Instructions Manual

7.3

Carrying out the initial commissioning

As soon as the heat pump is supplied with power during
the initial commissioning, an internal self-test starts au-
tomatically, whereby the heat pump checks itself and
any connected components for functional capability.
The sensor pin assignment is also checked during the
self-test and also the sensors used to make sure they
are in working order.
If the self-test was not successful, an error message ap-
pears on the controller display (see Chap. 10, "Trouble-
shooting and diagnosis").
• Switch on the circuit breaker, so that the heat pump is
supplied with power.
The heat pump starts, the controller software is initiali-
