3.2 ZONES MANAGEMENT BOARD
e zones management board can be congured using the selector switches present on the P.C.B. (2 Fig. 15) through which it is possible
to select from the following options:
No. OFF ON
S25
1
Homogeneous zone control:
the board controls the circulator (or valve) for every
zone, without considering the ow temperature for the
zone
Mixed zone control:
the board controls the circulator and the mixer for every
zone; the ow temperature is controlled by the mixer
2
1 mixed zone (Z2):
the board only controls a mixed zone
(when mixed zones control is selected on sw1)
2 mixed zones (Z2 and Z3):
the board controls two mixed zones
(when mixed zones control is selected on sw1)
3
Master board:
if communication is connected to the Immergas boiler,
the remote device (CAR
V2
) REPLACES the Room er-
mostat for the zone indicated as main on sw4
Slave board:
if communication is connected to the Immergas boiler,
the remote device (CAR
V2
) DOES NOT REPLACE the
Room ermostat for the zone indicated as main on sw4

Main zone = zone 1:
zone 1 can be controlled by CAR
V2
(if present in the
boiler)
Main zone = zone 2:
zone 2 can be controlled by CAR
V2
(if present in the
boiler)
5
Super CAR remote control:
Super CAR denes the ow temperature of the main
zone
Super CAR remote control:
SCAR denes the ow temperature of the entire system
6
Mixed zones max. temperature = 50°C:
the temperature adjusted on trimmer R12 and R13 has a
maximum limit = 50°C
Mixed zones max. temperature = 75°C:
the temperature adjusted on trimmer R12 and R13 has a
maximum limit = 75°C

- S26 (5) can only be modied if the Super C.A.R. remote control can be coupled with the Superior kW range boilers.
e following pages show the most representative examples of the types of systems used (mixed or not) in detail, with the relative set-
tings required on the dip switches of the board.
