3.7 DIM ERP CONNECTIONS TO ON/OFF ROOM THERMOSTATS.
WIRING DIAGRAM FOR DIM ERP CONNECTION TO ON-OFF ROOM THERMOSTATS.
Note:
All components represented in this diagram are optional.
Every zone can be controlled by the relative room thermostat.
On connecting the room thermostats, it is necessary to eliminate the jumpers present on the X9 terminal board of the zones
control unit.
If the Zones control unit is connected via BUS to Victrix Superior boilers (2021), the activation of the zones is determined by the
closure of the Room Thermostats and by the program on the Boiler menu (see boiler instruction booklet).
Key:
S20-1 - Room thermostat zone 1
S20-2 - Room thermostat zone 2
S20-3 - Room thermostat zone 3
