Just moved into a house with 5 heating zones, 4 of which are underfloor and connected to a Heatmiser UH2. The 4 UFH zones each have a thermostat - one old dial type and 3 Heatmiser Slimline programmable stats.
A few teething problems with a zone valve fitted the wrong way round but generally ok. I reprogrammed the time schedules to suit us as the previous owners had it on 24/7 @24 degC.
The zones seem to ignore the timing schedules and whilst they adhere to the selected temperature just call for heat whenever the room temperature drops below the set point even during a timing schedule "off" period.
Can these stats be wired incorrectly or something so they just work on temperature setting alone and by-pass the set timing schedules?
I have tried a factory reset on the stats and reset the timing schedules about a zillion times but still the odd zone kicks in in the middle of the day/night when it is set to be on an off period???
Any pointers or experience with these stats greatly appreciated.
