Make sure to strip the cable before placing it into the
terminals, and make sure that the copper is in good
condition.
A method of disconnection must always be installed in
compliance with the installation rules.
If the power supply cable is damaged, it must be replaced by a
qualified professional to avoid any risk of danger.
To access the terminals: remove the panel on the bottom left-
hand side (2 screws) and open the electrical box (8 screws).
The electrical power supply cable should first be inserted
through an exterior compression gland and then through a cable
grommet on the electrical box.

Heat Pump:
400V three-phase connection
• Three-phase monitor relay for 35kW HRC

Heat
Pump.
A phase monitor relay is installed to prevent phase failure, which
could damage the compressors. If the phases are reversed, it will
stop the power supply to the Heat Pump.
If the phase order is reversed, or there is a phase missing, the
relay cuts the power supply to the circuit board. A «BUS Err» error
message will appear. This is indicated on the phase monitor relay
by the orange light at the top being off and the green light at the
bottom being on. To correct the error, reverse the two phases on
the mains power terminal.
When the Pilot is switched on, a «BUS Err» error message will be
displayed. Reverse the two phases on the three-phase power
cable of the Heat Pump. Switch the power back on and check the
voltage on each phase.

If the length of the cable exceeds 15m, or if the network is susceptible to a drop in voltage
of more than 10V, use a thicker cable.
(*) The width of the ground cable must be equal to the thickest power supply cable.
