honeywell thermostats are great as they have little wire sprigs inside that can be moved to set the limits , upper and lower, we had a range from 15 degrees to 19 degrees.
new thermostats are digital electronic so will get set up with a temperature probe and then locked out with a passcode when i finish the decorating.
that said we didn't put the heating on auto until 12th December last year, just pinging it on for an hour in the evening when we got home. pointless heating an empty house. the morning chill at 04.30 was the spur for me to stick it on auto.
got switched off again in late feb when the building work started on the ground floor.
it does make me chuickle when people whack the stat up full saying the house will get hotter- no it won't it will only ghet hotter if you get the boiler to heat the water hotter by turning up the boiler stat. ours is currently set to 1 out of a possible 5 for hot water and heating on the combi. all that turning up the stat does is get the boiler banging away trying to get up to a temperature thats unattainable.
anyway get yourselves a roller trainer and you won't need to put the heating on , cycling for a few hours in the veneing will get you warm
