Room Thermostat Faulty?

[joben1]

Hi,

If a room thermostat clicks when it is adjusted does that mean that it is working? It is a Landis & Gyr Rad1.N.

The problem I'm having is the boiler fires when hot water is called for, but doesn't when central heating is called for.

Cheers

well simple basic tests with a multi meter will tell you if room thermostat is working,however first port of call would be the syncron motor on the c/h motorised valve if on system or do you have a combi ?

imho

Thanks for replying. I believe my system doesn't have a motorised or zone valve.

Do you have a clock?, and when turn the roomstat above the click, does the heating fire?

It will be the pump then.
Theremostats don't go wrong much. It is only a switch but it can be easily tested.
