I have an existing thermostat with six wires, 5 of which are connected. It is low voltage and solid wiring.
Connected are:
Brown
White
Yellow
Green
Blue
Not used:
Red
Is Nest Learning Thermostat compatible? I cannot read the post that Brown is connected to.
Thanks

Could you please post a picture of your current wiring as well as the details of your hvac setup (e.g heat pump, single stage electric etc).

I have a split system, updraft units, 20 year old Lennox, non heat pump. 3.5 ton and 4.0 ton units. 6 wires. I don’t have a photo but the wires are solid, brown (RC) white (W1) green (G) yellow (Y1) Blue (B) and red is spare. Low voltage controls. Hope that helps
