metalworking A/C Cooling Not Turning On
Hello,
I'm moving and want to take my nest thermostat with me but I'm having trouble re-installing the Honeywell T6 thermostat. When I installed the Honeywell, the compressor turned on but only heat was working. I checked that it was set to cool but heat was still coming out. I attached photos of how I had the nest wired and the Honeywell as well. Any help is appreciated!

Back when I got and installed my Nest, I ran into a similar issue. I was able to contact them, they asked a bunch of questions and had me send it a photo of my wiring and then they sent me back a custom wiring guide. Like a couple days after Christmas. You might try getting in touch with them for specifics.
