WIRING DIAGRAM WITH SEVERAL ZONES.
Using the K1 relay as the ''Main zone control'' and contacts 40
and 41 on the boiler for additional room thermostats, it is pos-
sible to connect several zones according to requirements. The
Comando Amico Remoto remote control always controls the
V2
main zone (zone 1), whereas the relative zone valve is always
and only managed by the K1 relay.
