Hi I am writing this to before I go out and buy a new programmer.
My progammer seems to work but when in the off position or when timer is off the boiler come on and it seems to be doing this from the room thermostat.
I have tested the voltage on the thermostat and when the programmer is off there is still 240v on the live is this correct. Should it have 240V or should it be 0V as programmer is off?
I seem to think if programmer is off there should be not voltage at thermostat.
I would welcome ny help I don't want to buy another programmer if its not required.
Many thanks
