Removing my old Honeywell thermostat to replace with the nest. I live in Florida and my ac unit is 10 years old. I’m not sure if I have conventional heat or a pump. I took a picture of the old one but I cannot upload it.
- Blue went to C
- Green went to G
- Yellow went to Y
- Orange went to O/B or W
- Red went to R with a silver little splitter thing to RC
- White went to W2/AUX.
After following the nest instructions I could not get the unit to power on.
