What to do if my DEVI devireg 530 Thermostat 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 530 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.
