Can I wire my Nest thermostat to the Heat Link?

[fatboyhouston]

I bought Nest Gen 2 a few years ago. Didn’t realise the thermostat connects to heat link via mesh, and so they have to be close. Our boiler is upstairs, but for obvious reasons the thermostat has to be downstairs.

Many times we’ve woken up to a cold house because the thermostat lost connection to the Heat Link. I am heartily sick of getting up in the cold to fiddle with the thermostat while wishing I had a simple wired thermostat that just works.

No doubt there are reasons why the connection keeps dropping - too much distance from the heat link, or maybe other devices interfering. But I’m not about to change everything else to accommodate a needy thermostat.

Is it possible to hard-wire a G2 nest thermostat to the heat link, and would that be the end of my connection problems? Otherwise this is going on eBay and I’m getting an old fashioned thermostat that works 100% of the time.

Thanks in advance for any advice!

Yes, you can hard wire a nest to the heat link. That addresses the connection problems.

No you cant

You cant hard wire the thermostat to the heat link, try using good quality Alkaline batteries, if you are still having problems you will have to move the heatlink if you dont want to move the thermostat, the thermostat being downstairs and the heatlink upstairs should not be a problem

Yes you can. Mine is. The 12v feed from the heat link to the nest also does the comms and allows you to split the nest and the heatlink by more than 30m.

Yes you can, that's what the T1 & T2 terminals are for

No they are not, T1 & T2 are the 12v supply to power the thermostat, they do not switch anything

The 12v T1 & T2 connections are also used for coms.

I stand corrected I never knew that, thank you

You can tell in the app if your using wireless or wired or both (mines a bit iffy on the wireless)
