ELECTRICAL SUPPLY AND CONNECTION 2.5
IDEA BOILERS WITH ELECTRIC IGNITION 2.5.1
The electrical installation and connection must be in accordance with the latest Local
Authority Regulations.
To simplify installation and servicing operations, all our gas boilers are fitted with a
P.C.B. TYPE A.
Connect the boiler to the electrical supply (see technical data § 1.4) ensuring that polarity
is correct (PH = phase into pole 1 - N = neutral into pole 2) and that it is earthed properly
The room thermostat should be connected between terminals No.7 and No.8 after remo-
ving the yellow-red cable bridge between them.
The time clock should be connected between terminals No.5 and No.6 after removing the
yellow-red cable bridge between them.
The terminal boards marked from No.53 to No.60 should be used to implement the
climatic controller “Micro”. Instructions for connection are detailed on the booklet

Ensure that pump has been connected between terminals 11 and
13.
After having removed the cable bridge between terminals 9
and 12, the three faston male terminals of overreun relay
should be connected as follows:
C(C) to terminal 12
NC(1) to terminal 10
NO(2) to terminal 9
WARNING
