We've one of the above which is programmed to come on in the morning at
06:30 Hrs with a target temp of 21.0 deg c The previous night it turns down to 10 deg c at 22:30 hrs.So I assume that it should hold, well not come on really!, the 10 deg till the next step in the morning when it cranks up to 21 ..
However its starting at 4 am with a target temp of 24 deg C clearly not desirable.
I've done a full reset in the installer menu to no avail. Anyone any ideas if theres something I've possibly overlooked, and yes its got a new set of duracell's ;)
Or is it time for a replacement?...
cheers..
