the pipe must be sealed and the pipe placed as high as possible in
the concrete layer. Alternatively, the sensor can be embedded di-
rectly 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 30m 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 func-
tion. 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. 4 - OPENING THE THERMOSTAT
1. Slide the power button down to Off "0".
2. Insert a small screwdriver into the central slot of the front cover
to press and hold the catch.
3. Then push the handle of the screwdriver downwards to release
the rear part from the front cover.
4. Carefully pull the rear part away from the front cover, starting
with the lower part of the thermostat.
