My CH is controlled by programmer not a timer, which should only call for heat at certain temperatures during different set periods during the day.
A few weeks ago the heating was coming on at some random times despite the actual room temperature being above the set temperature.
So I turned the temperature to off for all periods, but the boiler is still coming on at different times for different periods of time.
