Nest not triggering heating

[monkeyblonde]

We have had our Nest for 7 years, all fine until now.

it is connected via Heat Link to a Honeywell wall control. When activating the thermostat (turning it up) you can hear the Heat Link click, but this does not fire the heating. Can I assume it is the heating rather than the thermostat? No error messages on Nest.

Hey @monkeyblonde,

Thanks for reaching out. I'll do my best to get this sorted for you. If you hear your Heat Link click, it means that it's sending the signal to your boiler ( works as expected ). It sounds like the issue is somewhere else. Typically this happens when you have a stuck valve. I suggest reaching out to an installer so they can check your heating system.

Hi there. Just checking in. How's it going with your thermostat?

Since I haven't heard from you in a while, I'll have to close this thread. Should anything else come up, please open another thread and we'll take it from there. Have a good one and stay safe!
