The measured value should be within the specified range
according to the technical specifications.
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 specified range
according to the technical specifications.
If not, replace the NTC sensor.
Relay constantly on
Measure the voltage at terminal 1 & 2, (non-activated thermostat,
no light or green light). There should be no voltage at terminal 1 &
2. If voltage is measured replace the thermostat.
