We have Vaillant boiler (not combi) in Garage with a Honeywell Froststat. All working with heating on more or less all night at present as so cold. Want to get a pipestat fitted but plumber to busy at present. Just want to clarify operation of froststat please.
So heating on all day via programmer in airing cupboard - supposed to go off at 9.00 pm but staying on due to temperature of garage - all good.
Programmer turns heating back on at 8.00am until 9.00am. At 9.00am, programmer turns heating off and turns hot water on for 30 minutes. At 9.30 both heating and hot water are off on the programmer - presumably the 3 way valve stays in the hot water position. Frost stat does not seem to kick heating back on even though still freezing in garage.
Does this seem correct please.
