Homogeneous zone control:
the board controls the circulator (or valve) for every
1
zone, without considering the flow temperature for the
zone
1 mixed zone (Z2):
2
the board only controls a mixed zone
(when mixed zones control is selected on sw1)
Master board:
if communication is connected to the Immergas boiler,
3
the remote device (CAR
mostat for the zone indicated as main on sw4
Main zone = zone 1:
4
zone 1 can be controlled by CAR
boiler)
Super CAR remote control:
5
Super CAR defines the flow temperature of the main
zone
Mixed zones max. temperature = 50°C:
6
the temperature adjusted on trimmer R12 and R13 has a
maximum limit = 50°C
7
Normal functioning

Super CAR remote control:
SCAR defines the flow temperature of the entire system
Mixed zones max. temperature = 75°C:
the temperature adjusted on trimmer R12 and R13 has a
maximum limit = 75°C
