| ♥ 0 | The ‘set back’ temperature (the target when the programme is inactive) seems to be fixed at 5 degrees less than the ‘Comfort’ temperature (the target when programme is active). If a relatively high value is selected for the times when I want the floor to be heated it means that the floor is also heating when I don’t want it to (i.e. 5 degrees less than ‘Comfort’). I see how to change the ‘Comfort’ temperature in the device menu, but see no means of changing the ‘fall-back’ temperature – please advise.

And as it requires less energy its a lower running cost. Changing the setback temperature could mean a higher running cost on your behalf. Hi, I've just encountered the same problem. This is a major issue in causing the system to use power at unwanted times, this is wasteful and especially unwanted for users on a dynamic electricity tariff. The manual suggest the set back temperature can be set under advanced options, however this option does not seem to be available on the current version of the thermostat, please advise. Without this issue resolved I will need to return the thermostat. Add comment |
