Before switching on the heat pump, the control panel must be connected to the external machine.
To do this, pass the cable that is supplied inside the heat pump (located alongside the probe
harness) to the interior of the
FUSION
module. The hydraulic module has a series of cable ducts in
its roof, through one of which it will be possible to introduce the cable inside the equipment.
Finally, the connectors of the cable and the control panel should be connected at their ends.
A
cable with sufficient length should be provided inside the module
, in such a manner that it is
possible to open the front of the equipment without having to disconnect said cable and facilitate
any maintenance operation inside.
The cable supplied with the heat pump is 5 metres long. Where necessary, it can be extended up to
a maximum distance of 100 metres (section between 0.5÷1.25 mm
2
).
IMPORTANT: When working on the electrical installation of the heat pump, make sure that it is
disconnected from the electrical network.
IMPORTANT: Provide a sufficient length of cable inside the module in order to facilitate the
opening of the front cover.

Connecting the DHW diverter valve (G1)
The
FUSION
hydraulic module includes a motorised 3-way diverter valve, which is responsible for
directing the flow of water from the heat pump to the DHW heat exchanger or to the
heating/cooling system, according to the command signal received from it. To do this, a 3-wire
electrical hose must be routed from the terminal strip of the
DUAL CLIMA
heat pump to the inside
of the
FUSION
module. The hydraulic module has a series of cable ducts in its roof, through one of
which it will be possible to introduce the cable inside the equipment.
The electrical connection of the valve will be made between the general connection terminal of the
heat pump and the terminal strip of the
FUSION
module, by removing the cover to access it. The
following figures describe the form of connection of the motorised valve according to the heat
pump version available:

IMPORTANT: When working on the electrical installation of the heat pump, make sure that it is
disconnected from the electrical network.
