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.
