FIG. 3 - THERMOSTAT PLACEMENT
Mounting of sensor
The floor sensor contains a safety extra-low voltage (SELV) circuit,
allowing it to be placed as close to the floor surface as possible
without having to take account of the risk of shock should the sen-
sor cable become damaged. The two wires connecting the sensor
to the mounting box must be additionally insulated, e.g. shrink flex.
To prevent loose wires in the fixed installation from coming into
contact with the terminal block for the floor sensor, they must be
restrained using cable ties.
It is strongly recommended that the cable and sensor are placed in
a non-conductive installation pipe embedded in the floor. The end
of the pipe must be sealed and the pipe placed as high as possible
in the concrete layer. Alternatively, the sensor can be embedded di-
