What to do if my DEVI devireg 532 has no heat?
If your DEVI Thermostat isn't producing heat, start by checking the main fuse, the residual current device (RCD), and other safety devices. If those are fine, ensure all cables connected to the thermostat are properly installed. As a last resort, consider replacing the thermostat or the NTC sensor.
Why is my DEVI devireg 532 Thermostat always on?
If your DEVI Thermostat is providing constant heat, it could be due to a relay being constantly on or a floor sensor interrupt. Try replacing the thermostat or replacing the NTC sensor.
What to do if my DEVI Temperature Controller has no heat?
If your DEVI Temperature Controller is not producing heat, ensure all cables connected to the thermostat are correctly connected to the appropriate terminals, and all connections are secure. Also, verify that the RCD and contactor are switched on. If these steps don't resolve the issue, measure the voltage at terminals 2 and 4 when the temperature dial is turned up and the neon indicator is red. Check the heating cable resistance with an ohmmeter and make sure there is no leakage between the conductor and earth. Measure the ohm value of the NTC sensor wire. If problems persist, the thermostat or NTC sensor may need replacement.
Why is my DEVI Temperature Controller constantly heating?
If your DEVI Temperature Controller is constantly heating, measure the voltage at terminals 2 and 4 with the temperature turned down. Also, disconnect the external NTC sensor from terminals 5 and 6 on the thermostat. The thermostat or NTC sensor may need replacement. This issue may be caused by the relay constantly being on or a floor sensor open circuit.
