If the boiler requires it, the BUS connection can be made to the terminals as DIM BUS or 44-41, or 40-41 (see boiler instruction booklet).
On connecting the zone control Room Thermostats, it is necessary to eliminate the jumpers present in the zones control unit on ter-
minal board X9.
On connecting the marker safety thermostat, it is necessary to eliminate the jumper on X7.
Any CAR or Super CAR zone control must be connected directly to the boiler.

N.B.: for boilers other than Victrix Superior (2022), it is possible to control Zone 1 or Zone 2 as the main zone, indifferently. By default
(switch 4 on OFF) on the manifold set as Master will be controlled as the main Zone 1.
For Victrix Superior (2022) range of boilers, regardless of how switch 4 is set (ON or OFF), Zone 1 will still be controlled as the main one.
The electrical connections of the RT inlets of the zones control unit relating to the zone controlled by the remote device, must be left
free if the zone kit is connected to boilers other than Victrix Superior (2022).
N.B.: combined with the Victrix Superior (2022) range of boilers, the jumper of zone 1 (if remotely present) must be maintained (or
used for contacts of zone shutter valves).
