On the app it said that my system didn’t qualified for the Nest. I watched your video and followed the instructions and it worked perfectly. Thank you so much!

*I love it! **Fastly.Cool** and Warming environment perfectly controlled. Being able to track history temp and humidity takes all the guesswork out of the equation. Had it for two weeks now and it has been flawless!*

THANK YOU THANK YOU THANK YOU! Stupid Nest decided I didn’t deserve to see the directions, but I was able to connect my device with your help! ….and like 45 F-bombs. It was brutal.

should you switch off the circuit breaker when you are working with live wires?

According to the google home page you need a heat link wired directly to your combi heater in order to be able to use the learning thermostat. I am really confised now. There are 2 dofferent versions, one with and the other is without the heat link?

The newest nest thermostat will utilize the matter protocol. The implication is that it will be able to be used with homekit

Hi! We just installed our Nest 3 Gen and only the heat comes on. ?? We checked wires and everything checks out. Any suggestions??

How does this work with a dual fuel system with a thermostat that has OT1 & 0T2 wires?

[jenniferfinlinson]

My Nest isn't giving me the same screens once I plug it in to the baseplate. Any suggestions? Trying to add device to my home -- It scans the QR code, but doesn't ever add it to my home.

How can I remove the exclamation mark from setting on nest thermostat

Do you have to link anything else to the boiler?

[bennie]

This is how i connected mine two days ago, and today it disconnected from wifi due to low battery. Do i need a common wire? I only have 4 wires.

My friend thermostat is showing low battery. After my suggestion He took out his thermostat and charge with phone charger for six hours.
after putting back an hour or so
Thermostat shows battery low.

My question is can I move G to C for thermostat to get power? ( Green wire to C )
I know in your other video you mentioned that fan won't run doing this. But my question is does the air conditioning & furnace works doing this ?
After your reply. I have to help my friend to fix his thermostat which he lives an hour ago from me.
He wants me to come & fix it for him.

Do you have any low battery issue without C wire?

[natalyperales]

What if you have R, C, E1 and E2 wiring?
