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.
Mounting of thermostat with built-in sensor
The room sensor is used for comfort temperature regulation in rooms. The thermostat should be mounted on the wall
approx. 1.5 m above the floor in such a way as to allow free air circulation around it. Draughts and direct sunlight or
other heat sources must be avoided.
FIG. 3 – THERMOSTAT PLACEMENT
FIG. 4 – OPENING THE THERMOSTAT
1. Slide the power button down to Off “0”.
2. Release the front cover ONLY by inserting a small screwdriver into the slot at the centre of the bottom side of the
front cover to press and hold the catch securing the front cover.
3. Then carefully pull the front cover away, initially from the lower part of the thermostat, then from the upper part of
the thermostat.
