The measured value should be within the speciﬁ ed range

according to the technical speciﬁ cations.

If not, replace the NTC sensor.

Fault: Constant heat

Floor sensor interrupt

If disconnection of the external sensor (NTC) occurs, the

thermostat will be constant on (activated thermostat – red

light).

Disconnect the external NTC sensor at the terminal NTC, on

the thermostat.

Connect an ohm meter to the NTC sensor, measuring the

ohm value.

The measured value should be within speciﬁ ed range

according to the technical speciﬁ cations.

If not, replace the NTC sensor.

Relay constantly on

Measure the voltage at terminal 1 & 2, (non-activated ther-

mostat, no light or green light). There should be no voltage at

terminal 1 & 2. If voltage is measured replace the thermostat.
