I am trying to install a Nest Thermostat in my new place. Replacing a Honeywell thermostat. Ran it through the compatibility checker, and everything appeared to be good, but worried now. Old system has:
Y: yellow wire
G: green wire
C: blue wire
O/B: orange wire
W2 (with AUX to the left of the main label) white wire
R: red wire
System worked fine before, but after Nest install, no heat. I am worried that the W2 setup means I need a learning thermostat to make this work. Looking to see if that will fix my problem.
thank you.
