Technical Description of the Room Unit
C-RC-0011R is a wall-mount room unit with one inner sensor and a touchscreen, designed as a
standard unit on a CIB bus.
The unit is intended for operation in normal and chemically non-aggressive environment. No
maintenance is required. It consists of 2 parts: bottom with terminals and a cover with PCB and
control screen. It shall be fitted onto a diam. 60 recessed electric box or on a wall. There is an
opening for cable in the bottom part.
The unit is fitted with a touchscreen where special symbols are controlled by the module's CPU. The
unit is equipped with 5 capacitive keys in the bottom part of the screen, permitting to scroll between
screens and edit displayed values.
The unit can be controlled using either a simple display mode (a LOCK icon is shown on the display)
or a complete display mode. The display mode and items shown in the complete display mode can be
selected on the service level of the controller’s web interface.
Wiring the Room Unit
Warning: This controller may be wired by a qualified person only. Adjustment made by a layman
may cause damage to system components.
The Room Unit shall be wired by a 2-core cable of max. 1.5 mm2 cross secion to a standard CIB bus,
to screw terminals on the PCB. The right polarity shall be uncionditionally respected.
Adjustments to the Room Unit (configuration and HW address) are then done via the controller's
web interface.
After the CIB bus is energized, the Room Unit is ready for operation. Its HW address is printed on a
label on the PCB.
