Nest E and a Bryant Evo connex....
Nest E and a Bryant Evo connex....
On the thermostat the wiring is ABCD which is green, yellow, white, red.
I have a humidifier and it controls it within the thermostat.
Best I can find in their install literature is that the green and yellow are "data" wires and the red and white are the power and common.
What would be the nest E setup i only have the 4 wires to play with no extra to use as the "star" nest output.
Is this even possible?
thanks

Welcome to the forums.
I moved your post to its own thread.
Your Bryant is using communicating protocall. All functions on four wires.
With the nest.... if it's possible to use.... will need a wire for every function.
We need to know what your system is but 4 wires is not usually enough to convert to an analog thermostat.
Heat pump..... split A/C with gas furnace ???

thanks, makes sense...
no heat pump, just a bryant NG furnace variable speed fan with an external AC unit and an Aprilaire cascading humidifier
this is the thermo to furnace interface wiring setup, can confirm in furnace the Hum is directly wired to the hum.
