Solved this problem by reading the manuals “common issues” and hitting “reset” to skip the timer. The other was con...

Re: Nest Learning Thermostat Upgrade Help w/ EWC-ST-2E

Nice. Seems pretty simple. I’ll steal a C wire from somewhere for the bottom thermostat. Probably have to run a whole new cable upstairs as that’s only 3.

Re: Nest Learning Thermostat Upgrade Help w/ EWC-ST-2E

Edit: Job complete and thread closed. Super easy. Highly recommend doing it yourself. EWC is super fast and helpful to boot. Hi all. First time homeowner here who really doesn’t want to pay the $800 I was quoted to fix this. So I have an old pair of basic thermostats I want to upgrade to Google Nest...
