Why does the thermostat keep clicking on and off rather than heating up?
We have a OCC2 for under floor bathroom heating. The thermostat / clock keeps clicking on and off every few seconds, when it is supposed to be heating up. The display goes blank and then reappears with an audible click for a few seconds. What is happening?
The internal power supply of the thermostat has over the years deteriorated. Please contact your local dealer for replacement.
