CONNECTION
Before proceeding with electrical connection disconnect
mains. The electrical connection is ensured by the means of
screw terminals. Max cable diameter 2.5mm2.
The thermostats are equipped with an accelerating
resistance which must be connected to the mains in order
to ensure the indicated control performances. Terminal 4
should therefore be connected to neutral according to the
wiring diagram. This connection will also allow the pilot lamp
to light up to indicate that the unit is operating. See over for
