Connecting external temperature sensor
An external temperature sensor is required for the thermostat process of the floor thermostat
and thermostat with limiter. It is advisable to lay the temperature sensor in a protective pipe so
that it can be replaced later.
The wire of the temperature sensor supplies mains voltage and can be extended to 50 m
using suitable wires.
To avoid signal disturbances, do not lay the wire of the temperature sensor together with
mains cables.
Strip a maximum of 8 mm from the temperature sensor wire.
Connect temperature sensor according to connection diagram (Figure 6, 18).
