The connection to the mains is made with a 3-wire cable (Brown = Phase, Blue =
Neutral, Black = Control wire) via a connection box. In wet rooms such as kitchens and
bathrooms, the connection box must be installed at least 25 cm from the floor. The
installation must be equipped with a protective device such as a circuit breaker.
Do not connect to earth. Do not connect the pilot wire (black) to the ground.
If the power cable is damaged, it must be replaced by the manufacturer, his service
department or a similarly qualified person in order to avoid a hazard.
If the pilot or controlled device is protected by a 30mA earth leakage circuit breaker (e.g.
bathroom) it is necessary to protect the supply to the pilot wire on this circuit breaker.

WARNING:

management unit / chronothermostat. If the “PILOT WIRE” cable is black in colour it is
not used, safety regulations require it to be insulated and not connected to the cable
from the ground.
