Is it a wireless thermostat?
Can you take it off the wall and sit it under the boiler?
You rate me as "poor"?
the thermostat is already under the boiler on the kitchen worktop.
The poor rating was meant for the service I was getting from just answer, not for your answer
Both lights are on all the time,if I reduce the temp on the thermostat the green light goes out , then increase and the green lights up again
