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
sensor 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
directly in the floor. The sensor cable must be led through a
separate conduit or segregated from power cables.
The floor sensor must be centred between loops of heating cable.
The sensor cable may be extended up to 100 m by means of a
separate two-core cable. Two vacant wires in a multi-core cable
used, for example, to supply current to the floor heating cable must
not be used. The switching peaks of such current supply lines
may create interference signals that prevent optimum thermostat
function. If a shielded cable is used, the shield must not be
connected to earth (PE). The two-core cable must be placed in a
separate pipe or segregated from power cables in some other way.
