Nest with C wire adapter

Andrew134 — Sat, 31 Dec 2022 01:19:32 GMT

I am curious if a nest thermostat (any version) with a ‘C wire adapter’ will work with my existing heating system.
I have no wires from my furnace (basement) to my thermostat(upstairs).

Will the nest thermostat communicate directly to the c wire adapter and turn the heat/ cooling on/off?

You do not have any wires to your existing Tstat?

Is it wireless tstat?

The nest needs wires connected to it even with the power connector there needs to be 2 wires from Nest to the power connector device.

What kind of heating system do you have? Do you have AC and heat or is it heat only?

I have a Goodman heat pump (heat/cool) with propane back up (emergency heat) for really cold weather.
We’re currently running a Honeywell wireless thermostat that communicates with a base station attached to the furnace. The base station is wired to the furnace.
Honeywell thermostat: TH6320R 1004

Honeywell base station: THM5320R

Nest needs wiring. It cannot talk to the honeywell base station.

You would need to snake a 5 conductor thermostat cable to the location you want the Nest.
