If connected to a system fitted with a REHAU BA Master Controller these
limits can be adjusted using the BA menu. Adjusting the limits this way will
control either the min/max temperatures for all floor sensors within the group.
Note:
The REHAU CT2 Programmable Room Sensor can be fitted with a
floor sensor. However this is an optional extra, and will require the floor
sensor as a separate part REHAU Art No. 225385.
Where REHAU TD sensors are installed within the system. The floor
limit sensor must be fitted or the system will not work correctly.

5.3.2 Floor Sensor Option (TD Sensor Only)
Being able to control the minimum or maximum temperatures of
floors provides two functions. By controlling the maximum floor
temperature you can prevent over heating of the floor. This may
be required where special floor coverings are used. Controlling the
minimum temperature of the floor surface can create greater comfort
levels for the end user keeping the floor at a minimum temperature.
5.3.3 Connecting the Floor Sensor
Sensors requiring floor sensors wire up as shown in Fig. 33.
Sensors with a floor sensor have a mechanical jumper on the right
hand side of the printed circuit board controlling the minimum or
maximum temperature. The temperature limits are adjustable within
the sub menu of the BA controller. If heating only is required then this
can be adjusted within the CT2 Programmable Room Sensor sub
menu (HiLo) see Fig. 34 for Jumper position.
If however, the floor sensor is connected to a REHAU CT2
Programmable Room Sensor as part of a group (see section 10).

32b. Positioning jumper (side view of TM sensor)
Sensors with a remote air sensor have a mechanical jumper on
the right hand side of the printed circuit board controlling the
sensor function.
If the sensor is to be positioned within the space then leave the
mechanical jumper parked on one of the terminal pins. The sensor
should be supplied with the mechanical jumper in this position.
If remote air temperature reading is required then gently remove
the jumper and position it on both the terminal pins (as shown in
Fig 32b).
