For three phases connections, L1 / L2 / L3 are used for phases.
Use the cable glands and grommets provided inside the heat pump to route cables.
Since this machine is installed outdoors, connections must be made with a polychloroprene cable or with standard
cables routed in protective conduit.
The electrical cables must be buried in pliable electrical conduit (red) at a depth of 50 cm (85 cm under a roadway
or path). When an underground cable conduit crosses another cable or other utility (water, gas...), they must be
separated by a distance of at least 20 cm (8").
Heat pump power supply must be protected by a system in conformity with local laws.
Heating priority
It is possible to connect the water filtration pump to the heat pump, in order to start the filtration pump if the water is
not at desired temperature.
To connect the heating priority you need a normally open relay (contactor) with 230V AC coil.
Wiring connections:
Connect the relay coil (A1 and A2) with the terminals P1 and P2 of the heat pump
Connect the relay in and out of the normally open contact in parallel with the relay of the filtration pump timer
Wiring diagram:

Parameter to confirm heating priority:
Check if the setting of heating priority (parameter #9) is set to 1.
If not, please contact our hotline.
