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. At
the same, the sensor configuration is checked, the
phase sequence of the AC supply is determined and the
functioning of the sensors in use is checked.
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 initial-
