16. 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 monophase + 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
...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 lid and gain access to the wiring (Figure 10).
The 2A fast-blowing fuses are in cor po rated in the power supply terminal block (to check or replace the fuses, pull out the

The LuNA3 COMFOrT AIr boiler is controlled by a radiofrequency (wireless) remote control / climate controller. The
system comprises two separate units:
• The climate controller, known as rFrc01, is the boiler control unit which is used to set parameters, temperatures,
operating states and view information and fault messages;
• The base, known as rFiu01, acts as an interface between the climate controller and the electronic card of the boi-
ler.
• Connect the wires from boiler terminal block M2 (Fig. 12) as illustrated in figure C.

WarninG: the base is powered at LOW VOLTAGE. Do not connect it to the 230 V mains supply. For electrical connec-
tions, see sections 26 and 31.
