Thermostat compatibility

[tfarr]

Hello!

I need some help to determine what I need for compatibility here.

I believe the wall controls are just data fed and that the real wiring is attached to the furnace itself in the basement. Looking to upgrade to a smart thermostat from this Honeywell but I am concerned that there may be more than meets the eye with this upgrade. 

TIA

Hi tfarr, 

Thanks for posting here in the Community forum and for showing interest with our Nest Thermostats.

Wire labels such as 1 2 3 and 4 indicate a proprietary system. Proprietary systems usually only work with thermostats made by the same manufacturer. But some proprietary systems may also have the option to use standard heating system wires. Contact a local HVAC professional and have them check if your proprietary system can be rewired to be Nest compatible.

Keep us posted. We're here if you have any other questions.

Best,

Zoe.
