Room Sensor Internal Connections
Sensors can be mounted directly onto the electrical back box either flush
or surface mounted. Remove the front cover of the sensor by gently lifting
the front cover. Remove the sensor fascia to expose the fixing holes (Refer
to Fig. 31 for Connecting Sensors).
Care must be taken not to damage the circuitry or the
components on the printed circuit board at this point.
Care should also be taken not to deform the sensor back plate
when fixing to the back box.
Fix the sensor to the back box using the holes provided on the back plate
Do not over tighten the fixing screws and deform the back plate.
5.3.1 Connect the Wiring
Sensor types REHAU TP, CT2, TA, TM & TD
All sensor types are connected dependent upon which wiring
configuration used on the first fix, Refer to Fig. 31, or Fig. 32 .
When the wiring of the sensor is complete refit the fascia plate and
the sensor front cover.
5.3.1a Connecting the Remote Air Sensor
The sensor is connected to the REHAU TM sensor as shown in Fig.
32a. When the sensor is fitted the REHAU TM sensor function will
operate in the same way.
Unlike the REHAU TD floor sensor the remote air sensor is
only fitted when required and can only be used with the
REHAU TM sensor
