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…

The heat link is wired to boiler But the nest display where you can change it on the unit etc is wireless via threads to the heat link.

I looked at the Hive system as I quiet liked the display etc BUT it cannot be wired, it runs via batteries and I didn’t want to have to keep replacing batteries.  The nest heat link has 2 batteries and run from power also so batteries are effectively a backup for power outages etc is my understanding, but could be wrong.

It’s just strange as the nest-e been working fine until recently… I’m partly thinking its the programmer as every time power goes out now it go to asking for time, date, year etc… it seems to remember the times I set it to come on/go off but it seems that isn’t being used until I set the time/date/year etc.

Previously the power would go out and it was fine but now it doesn’t keep it any more.  I’ve looked but I don’t see any mention of a battery anywhere.  I just says if power is off more than 3hrs, you need to reset the time/date etc but it’s not been off for more than a few minutes so unsure why its prompting.  It maybe as simply as the programmer has gone faulty and I need to replace it but not sure.

Plus it seems Nest isn’t able to control the boiler even when it is on as not going to the set temp so half of me things – its the programmer, once it is set then it behaves, another part of me things, maybe it’s the nest-e….

Thanks for link, will take a look at that and see if its compatible/will work if I don’t get anywhere with the Nest-E / programmer.
