Before carrying out electrical work:
Risk of death by electric shock!
Any work on the electrical equipment of the heat pump shall only be per-
formed by professional electricians!
Risk of death by electric shock!
Install circuit breakers for personal protection.
For the power lines, use standard cables of sufficient capacity. Other-
wise there is a risk of short circuits, overheating / fire.
When installing power lines, do not apply tension to the cables. Loosen-
ing connections pose a risk of cables slipping from terminals / breaking;
this can result in overheating / fire.
Master switch on module (beside touch screen): If master switch is acti-
vated (switch is lit), the indoor and outdoor module are ready for opera-
tion.
The exterior temperature sensor is connected to terminals 5o / 5u.
The external disconnection is optionally connected to terminals 49/50.
The electrical disconnection of the outdoor module can take place from
the indoor module (service purposes).
Attention: However, voltage supply of the 3 feed lines- heating element,
compressor, control voltage, is applied to the main terminals/ relays of the
device!
Should it be necessary, disconnect all feed lines from the house fuse
box.
