3.5.2.2 - Pilot: 400V three phase connection
In case of a PERMANENT POOL:
Disconnect the heating circuit circulator
pump which is pre-wired to the HRC Pilot on
terminals 5 and 6 and reconnect it to terminals
2 and 3. Then connect the Cchauf1 circulator
pump for the swimming pool on terminals 5
and 6.
The Pilot is always pre-set at the factory
for 230V single phase operation.
In order to operate in 400V three phase, you
will need to remove a bridge between the three
phase terminals (see diagram below).
