Cable temperature

sensor for under floor

heating

QAP1030/UFH

Use

The cable temperature sensor is used in electrical floor and hydronic floor heating

systems to monitor and limit the floor temperature.

Owing to its insulation, the sensor is especially suited for use with controllers or room

thermostats whose sensor signal inputs are not galvanically separated from the

AC 230 V mains network.
