Use a properly sized main electrical switch.
The power supply for the heat pump must be grounded.
Electrical wiring must be done by a qualified technician.
The electrical wiring must be carried out in compliance
with local regulations.
The electrical wiring must be done with the unit
disconnected.
Wiring must be securely fastened.
Do not let the wiring touch together.
Make sure that the main power supply complies with the
data plate.
Make sure that the power, wiring and power socket comply
with the power of the appliance.
To connect the appliance to the power supply, proceed as
follows (Figure 5-10):
1.- Remove the junction box cover on the right side of the
appliance (Figure 5-9);
2.- Secure the end of the power cable in the cable clamp;
3.- Connect the terminals of the power cable to the terminals
in the positions G (Ground), N (Neutral) and L (Line).
If you want to control the appliance from an external signal,
connect the pair of cables between HS and GND for the
heating demand and CS and GND for the cooling demand
(Figure 5-10).
By the factory, the remote ON-OFF input is disabled. If you
want to enable it, you need to act on Parameter 01 (section
7.5). This input has priority over the heating, cooling and
sanitary demands.
