ELECTRICAL CONNECTIONS - WIRING DIAGRAMS
The boiler must be connected to an earthed, single-phase 220-230V-50 Hz mains supply by means of a three-
wire cable, ensuring that connections to the LINE and NEUTRAL terminals are made correctly.
A bipolar switch must be used with contacts opening to at least 3 mm.
The power lead must only be replaced by another with the following characteristics: "HAR H05 VV-F" 3 X 0.75
mm
.

The boiler is equipped with a 1 m lead for connection of the remote control unit. If this is not long enough for
the intended control unit position it must be replaced with a lead of appropriate length.
The control unit must be fitted on an internal wall about 1.5 m above the floor. Do not fit near heat sources or
in direct sunlight. Avoid installation in corners, alcoves, behind doors or curtains etc.
Attach the unit to the wall with the supplied expansion plugs. A through-hole is previewed to allow for passage
of the electrical wiring. The control unit can also be fitted directly on a standard 3-module junction box.
Connection to the boiler requires two wires with a minimum cross-section of 0.5 mm
50 m in length. The positive pole is to be connected to terminal 5 and the negative pole to terminal 4.
Accidental inversion of polarity, while not damaging the control unit, will stop it functioning.
Installation must be made in compliance with safety REGULATIONS IN FORCE.
Make a good earth connection.
