Siem ens HRC3.2 – Room controller CM2N6314en
Building Technologies 2016-12-23
The sizing and fuse protection of the power supply cables depends on the total load
and on local regulations. The cables must be secured with cable restraints.
· The volt-free relay outputs allow switching of loads up to AC 250 V, 4 A. The cable
dimensions depend on the connected load and the local installation regulations. The
circuits must be externally fused (£ 10 A), as there are no internal fuses.
· The cables must be secured with cable restraints.
· The relay group on connector X4 may EITHER be connected to mains voltage 230 V
OR to SELV 24 V. The same restriction is also valid for connector X5.
Mixed operation is not allowed. However, it is possible to connect mains voltage to
X4 and SELV voltage to X5 and vice versa.

Caution
· The fans must not be connected in parallel (use cut-off relays).
Mounting instructions
The room controller can be mounted in any orientation, as follows:
6314z06
6314z07
Rail mounting
The housing base is designed for
snap-mounting on DIN rails, type
EN50022-35 x 7.5, (can be released
with a screwdriver).
Surface mounting
There are four drill holes for screw
mounting (see “Dimensions” for drilling
diagram). The housing base is fitted
with raised supports.
Screws: Max. diameter 3.5 mm
· The HRC3.2 room controller is installed in the corridor with other installed devices,
behind the plasterboard.
· There must be a means of dissipating the heat generated during operation.
Adequate air circulation must be ensured.
· Subject to certain conditions, the HRC3.2 room controller can be installed in
suspended ceilings. Potential noise problems caused by the switching of relays
should be resolved in a sample room.
· As installation is the same for all types of room (e.g. single rooms or suites), it is
recommended that a sample room should be set up for each room type, in
cooperation with the electrical installer.
· Ensure the room controller is accessible for commissioning and service work.
· The card holder is intended for fixed installation in a dry, enclosed space.
· Commissioning must be carried out by trained personnel only
