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 sepa-
rate 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 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.
1.6 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. No external sensor is connected.
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 thermo-
stat.
