I also had the same analog thermostat that came with my '22 FQS Titanium. Per the ORV brochure, should of had a digital thermostat. Had my dealer contact ORV about the change, No luck, I got what I got due to supply issues.
I also upgraded to what I thought should of been installed by ORV Titanium model, Coleman Mach Digital AC HC Black 8330-3862.
When I removed the analog unit, I really didn't care for the mounting method used, 2 screws through the thin veneer. So I glued some additional wood behind the veneer and drilled starter holes in the same location to mount the new thermostat. No issues on the wiring, but one wire was of a different color.
