Data Sheet for Product

AC 230 V
supply cables
The sizing and fuse protection of the power supply cables depends on the total load
and on local regulations. The supply cables must be secured with cable restraints.
Volt-free
relay outputs
AC 230 V
• Loads up to AC 250 V, 5 A (4 A) can be switched with the volt-free relay outputs
• The cable sizing depends on the connected load and on 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 X3 may EITHER be connected to mains voltage 230 V
OR to SELV 24 V. The same restriction is also valid for connector X4.
Mixed operation is not allowed. However, it is possible to connect mains voltage to
X3 and SELV voltage to X4 and vice versa.

Caution
• The fans must not
be connected in parallel (use separating relays!)
Mounting
• The HRC3.1 room controller is installed in the corridor with other installed devices,
behind the wall.
• There must be a means of dissipating the heat generated during operation.
Adequate air circulation must be ensured.
• Subject to certain conditions, the HRC3.1 room controller can be installed in
suspended ceilings. Potential noise problems caused by the switching of relays
should be clarified 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 in cooperation with the electrical
installer, for each room type.
• Ensure that there is access to the room controller for commissioning and service
work.
• The device is designed for fixed installation in a dry, enclosed space.
• Commissioning must be carried out by trained personnel only
Local safety and installation regulations must be observed
Konnex building bus
(terminal block X11)
• EIB standard cable with 2 twisted pairs for connection of the Konnex gateway to all
room controllers (2 wires are spare or for PPS2)
Wiring
• EIB standards must be observed
• No bus termination resistances are required.
PPS2 interface
(terminal block X11)
As a maximum two room devices (room unit QAX84.1) can be connected to PPS2.
• Cable with 2 twisted pairs for connection of the Controller to all room units (2 wires
are spare or for Konnex)
