R wire not connected even with furnace on

[ejfg]

Furnace/boiler are connected, but power went off on Nest a few days ago without any clear issue. In the past it has been that the pressure on my boiler is too low, but that's not the case this time. It says that the R wire is not connected, but there have been no changes...

Hello ejfg,

I'm sorry to hear about the issue that you're having with your Nest thermostat that shows no power. Let's see what's going on.

A few questions: could you tell us the wire report or message code you're getting? What type of Nest thermostat do you have? Also, please tell us the wiring configuration of it.

Have a look at this article and let us know if you need more help.

Thanks,
Mark
