Nest question

I spoke with nest support to see how to wire my new Nest learning thermostat. I had wires that where not listed on there compatibility checker. The wires I had questions about are hooked up to u1. They gave me a diagram to follow and said to not to use those 2 wires, this does not sound right to me. I have a model Gsx130301be outside Gmss920603bnaa inside. Here is a pic of my wiring.

You will need to enter the configuration menu on that Honeywell TH8320R thermostat to see what the U terminals are configured to control or check the other end of the black and orange wire to see what they are connected to. (Probably a humidifier)

The Nest thermostat will control a 2 wire humidistat but a separate relay may be required.

If you wanted internet control of your equipment a 65 dollar internet gateway could have been added to your Honeywell thermostat.

Man why would you get rid of that t stat for IMO a crappy nest???

That vision pro 8000 is far superior to anything out there on the market. Especially with red link..

If you really want to part with it let me know. Im in the market. Been wanting to get rid of my honeywell t6 pro.
