Hi. I have the above combi boiler. Ever since we turned it to heating for the colder weather it comes on at the times that had been programmed in by another tenant. I have tried moving it to another setting to see if we could just set it to the thermostat instead or even just use override to turn on as needed but keeps coming on at the preprogrammed times whether needed or not. I really want to stop getting up at 3am to turn it off, please help :)
