ELECTRICAL CONNECTION OF THE APPLIANCE
Wiring rules
-
The appliance must be powered with single phase 230 V 50 Hz.
-
The power supply to the appliance must be directly connected to
the household power system after the circuit breaker and without
intermediate switch.
-
The unit will connect to the household power system through its
power cable via a power socket. In humid areas such as bathrooms
and kitchens, the power socket must be installed at 25 cm (9.8”)
minimum above the floor.
-
Connection to the earth is prohibited. Do not connect the
pilot wire (black wire) to the earth.
-
The power supply must be directly connected to the household
power system after the double-pole circuit breaker in accordance
with installation rules.
-
If the power cable is damaged, it must be replaced by the manufacturer,
its customer service or similar qualified persons in order to avoid any
risks.
-
If you use the pilot wire and it is protected by a 30mA residual-
current circuit breaker (e.g. bathroom), the pilot wire power must be
protected on this residual-current circuit breaker.
-
If you want to use a load-shedding device, choose one with a pilot
wire outlet rather than one with power outlet, so as not to damage
the thermostat.
