ELECTRONIC BOARDS
GAHP-AR Unit electronic boards (S61+AR11)
In the electrical panel on the GAHP-AR unit there are:
▶
Electronic board S61 (Figure 1.15 p. 18), with micropro-
cessor, it controls the appliance and displays data, messag-
es and operative codes. The appliance is monitored and
programmed by interacting with the display and the knob.
▶
Satellite WAR11 electronic board (Figure 1.16 p. 19), in-
terconnected to the S61 board and located next to it, used
to control the cycle switching valve and to control defrosting
operations of the GAHP unit.
