WIRING DIAGRAM WITH 2 ZONES.
The control unit is set up for the direct management of a maxi-
mum of 2 zones, which is carried out with relay 1 and 2. Relay
1 must be configured as the "Main zone control", whereas relay
2 must be configured as the "Secondary zone control". Relay
3 can be used for one of the functions indicated in the boiler
instruction booklet.
The CAR
V2
must be connected to terminals 41 and 44 complying
with the polarity and eliminating the X40 jumper. Moreover, it
must be set with On/Off operation and must control zone 1,
while the room thermostat controls zone 2.

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
V2
Comando Amico Remoto remote control always controls the
main zone (zone 1), whereas the relative zone valve is always and
only managed by the K1 relay. Relays 2 and 3 can be used for
one of the functions indicated in the boiler instruction booklet.
The CAR
V2
must be connected to terminals 41 and 44 complying
with the polarity and eliminating the X40 jumper. Moreover, it
must be set with On/Off operation, while the room thermostats
require zone valves with end run contact The contact must be
closed with valve open hydraulically.
