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.
