Installation manual for
EVC-RZHC-HUB Room/Zone-Hub with cabinet
The room / zone hub is designed for the connection of a room controller,
two volume flow controllers with actuator LMVAX-D3-MOD, a CO2, VOC
or humidity sensor, a heating and cooling valve, a change-over sensor, a
presence detector and a condensation monitor or window contact.
The Hub module is used to supply power to the connected actuators and
sensors, as well as signal distribution. Factory-made, the hub is
delivered in a surface-mounted housing.
After removal from the housing, the base board is also suitable for
mounting on DIN rail

1. Mounting
1.1 Surface mounting
Factory-made, the hub is delivered in a surface-mounted housing. The distances between
the holes for wall mounting are shown in the drawing below.
Alternatively, the base board can be removed from the housing. The board is then suitable
for mounting on a DIN rail.
2. Connection of the RZHC-HUB to the master cabinet EVC-MC
A free network port of the main switch cabinet EVC-MC is connected to the RZHC-HUB at
the "Controller BACnet/Modbus" port.
Connection via RJ45 network cable.
Total cable length: max. 150 m (AWG 26/7)
Alternatively, a network installation cable + network connector RJ45 can also be used for
on-site assembly. Total cable length: max. 250 m (AWG 23)
