I have programmed th ethermostat to comfort temp 20 degrees and setback temp 10 degrees but the heating did not swich on when timed to do so and the room temp was 18 degrees so i presumed it should have worked! where should the slider at the bottom and on the left be positioned? i had it set on Auto at the bottom and run on the left? Any help would be good. Thanks
The clock on the room handset is not connecting to the box the batteries have been replaced and the connection has been made as the green light is on and the sun/moon button will turn the boiler on and off just not the timer?
