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 neces-
sary to eliminate the jumpers present in the zones control unit
on terminal board X9.
On connecting the DIM ERP safety thermostat, it is necessary to
eliminate the jumper on X7.
Any C.A.R.
V2
or Super C.A.R. zone control must be connected
directly to the boiler.
N.B.:
for boilers other than Victrix Superior (new version 2021), it is
possible to control Zone 1 or Zone 2 as the main zone, indifferently.
By default (switch 4 on ON) on the manifold set as Master will be
controlled as the main Zone 2.
For Victrix Superior range boilers (new version 2021), regardless
of how switch 4 is set (ON or OFF), Zone 1 will still be controlled
as the main one.
In the event that two or more zones are used, the C.A.R.V2 o
Super C.A.R. must be set with on-off operation (see instructions
in the relative booklet).
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 DIM ERP is connected to boilers other than Victrix
Superior (new version 2021).
N.B.:
combined with the Victrix Superior range boiler (new version
2021), the jumper of zone 1 (if remotely present) must be maintained
(or used for contacts of zone shutter valves).
