Reply To: Boiler Query Hi all, So been visiting parents for a few days and it seems, the power went out some point over the last week and must of been a longer than…

So the programmer on my ideal logic 24 boiler is in-built into the boiler so to speak.  I’ve set it to come on at certain times of the day and to then go off at certain times each day.  Same schedule every day.  In order for boiler to use programmer it is set to Run mode.

The Nest-E basically is set to the temps I want it to be in the property i.e. 21 if I’m home, if I’m away, I set it to ECO mode which is set to 15C.  Therefore boiler should only come on when programmer is set to come on AND temp in property is below 21 (if home) or 15 if not home, if not, it stays off.

However, neither is happening and it seems to be defaulting to around 28C somehow, unsure why…

Reason I don’t set boiler to Continuous and then let Nest-E turn boiler on and off is:-

1. If temp gets low of a night, it wants to turn boiler on and I don’t seem to be able to stop it.  I know there is a fail safe/emergency mode that if temps get real low, it will turn boiler on to prevent pipes freezing etc but Nest-E wants to turn boiler on way above that level i.e. 3 or 4 degrees i seem to recall.
2. As place gets power cuts, varies on how often, not daily or weekly but came be every couple or few months, I’ve noticed Nest-E doesn’t always re-connect so not ideal, hence left it that programmer turns it on or off and Nest simple tells it what temp to be at, which has been working fine for 4 months or so.

Perhaps I need some sort of all in 1 device i.e. WIFI thermostat & programmer that’s wired to boiler so it’s just 1 unit that does it all rather than 2 units and talk to each other, if that exists…

Thanks
