Hi All,
After a bit of advice please, the problem I have is the boiler fires up to heat the hot water cylinder regardless of the timer being set for it to come on or not.
I can set the timer to OFF and the boiler is still going, if I go upstairs and turn down the cylinder thermostat that turns the boiler off.
Central heating is fine, programmer is set to always on as my Tado controls thats, and that turns off and on the heating fine.

Does this sound like a faulty programmer? or something worse?
Thanks!
