FIG. 2 - WARNING – Important Safety Instructions
Disconnect the power supply before carrying out any installation or
maintenance work on this thermostat and associated components.
The thermostat and associated components should only be installed
by a competent person (i.e. a qualified electrician). Electrical instal-
lation must be in accordance with appropriate statutory regulations.
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
