Connecting the mains supply
Electrical safety of the appliance is only guaranteed by correct grounding,
in compliance with the applicable laws and regulations.
Connect the boiler to a 230V mon ground power supply by
means of the three-pin cable supplied with it and make sure you connect
polarities correctly.
Use a double-pole switch with a contact separation of at least 3mm in
both poles.
In case you replace the power supply cable fit a HAR H05 VV-F’
3x0.75mm
2
cable with an 8mm diameter max.
…access to the power supply terminal block
• isolate the electrical supply to the boiler by the double-pole switch;
• unscrew the two screws securing the control board to the boiler;
• rotate the control board;
• unscrew the screw securing the lid and gain access to the wiring (Fi-
gure 8).
A 2A fast-blowing fuse is in-
corporated in the power supply
terminal block (to check or replace
the fuse, pull out the black fuse
carrier).

Fitting a room thermostat
• gain access to the power supply terminal block (Figu-
re 9) as described in the previous section;
• remove the jumper placed on terminals (1) and (2);
• insert the duplex cable through the core hitch and
connect it to the two terminals.
Connecting a programming clock
• remove the two screws securing the control board to the boiler and
hinge it downward;
• remove the 2 screws fixing the control board cover and hinge it
upward;
• connect the programming clock motor to the main PCB M3 connector
(terminals 18 and 20);
• connect the programming clock switch to the M3 connector terminals
(17 and 19) and remove the jumper.
In case you are fitting a battery-operated programming clock do not
connect the M3 connector terminals (18 and 20).
