I'm switching from a Honeywell to a Nest thermostat.
The following wires are in use on the Honeywell one:
- R < red
- C < blue
- W-O/B < white
- Y < yellow
- G < green
On the Nest side I connected as follow:
Rh, C, W1, Y, G All my equipment (heating, cooling and fan) are detected. However, when performing a test, nothing fires up
I then moved the white wire from W1 to O/C to no avail.
Same when moving the red wire from Rh to Rc.
When putting the Honeywell thermostat back on, everything is working just fine.
What am I missing?
Thanks for reaching out. I'm sorry to hear that you're having an issue with setting up your Nest Thermostat. I'd love to know more about this and I have a few questions:
Looking forward to your response.
