I wanted to see if Nest is compatible with a H1 H2 wiring system. Don’t go by the colors of the wires.

What kind of heating system is this for?
It should be Red is power and White is the return back to system to trigger the heat on and off.
If you use the regular Nest you will need to run a new cable to have a C wire.
The Learning Nest is supposed to work without a C wire.

12-11-2022 03:29 AM
Forced hot air.

I have the nest gen 3 and I currently have it set up for H1 and H2 for my 2 stage furnace.

How is it wired?

OK go to the furnace and take the front cover off.
Find the thermostat wires and take picture of all the screws in a row showing the labels on the screws.
We need to see if this is a standard heating system and if there is a C common terminal.

It an HVAC system. No furnace. All forced air.

Is it a natural gas heating system?
Can you go to the system and show us a picture of the thermostat wiring connected to the system?
The regular Nest non learning version needs 3 wires to work and looks like you only have 2 wires coming out of the wall.
