Old HW thermostat has a yellow wire which connects to Y but then continues over to W. System is a heat pump.
So which or both (Y or W) go in compatibility checker?
When connecting to Nest does that yellow wire go to Y or W.
Other wires: red to R, white (or beige) to O, green to G
Thanks for any help,
Clearly a jumper but not a typical one since it's all 1 wire. So, would I connect yellow to Y or W on the Nest. I don't know which of the 2 jumped connections to eliminate and which to use.
Hard to see but the yellow wire is stripped in about a 1/2 inch wide section 3 inches from the end and connected to Y but then the end is stripped and connected to W. Since I can only connect this yellow wire to one terminal I have to pick either Y or W, to put it another way.
It looks like we haven't heard back from the OP so I'm going to go ahead and lock the thread. If you have any further questions or concerns, feel free to create a new thread.
Have a great day,
