I will be away from my desk sometimes, but will respond as soon as I can.You might see automated adverts for phone support. I'm not available for a phone call today, but we can continue via this Q&A topic.
Please tell me more about your system...What is the make and model of your controller?How many underfloor zones do you have?Do you also have radiators?What is the heat source?
Have you programmed a night-time set-back temperature on this particular thermostat?
Hm. That should indeed mean no set-back. Unless of course it's faulty.I can't see from the manual how this thermostat shows that it's calling for heat - is it the LED on the left? Are you able to catch it when it's calling for heat at an unprogrammed moment? Is that LED lit up?
The manufacturer says that the battery type should be "3.6 V lithium battery, 2100 mAh, size AA".What have you fitted?
Hm. Might just be worth fitting brand new batteries before deeming it faulty.
Are you certain that it's not a 1.5V alkaline AA?
Cool. I don't mean to imply any incompetence on your part - it's just worth being extra sure :-)
Since it's wireless, you can just remove its battery :-)
Yes indeed. I'll await your news. This topic will stay open for many days, so there's no rush.
