Right I have changed the ref things and reset then done times and dates so fingers crossed,,, just to clear up if I have set stat to 15 the boiler should not come on unless it drops to 15??????
i have just had one of these fit and I have set all programs as it says but the boiler is coming on when it shouldn't ????????????? Set at 16 and screen says 20 but yet boiler on ???????? The plumber left the boiler temp up full ??? Help
