You will get better help if you can provide the make and model of the A/C unit and thermostat.

Which thermostat did you use? Run through the set up according to the manufacturer instructions.

It was installed by the REV Service Center and worked for a couple of days.

Download the manual for your thermostat and check the set up. But first, take the cover off the thermostat and there should be a small glass fuse. Take the fuse out for about 1 minute to see if this resets the thermostat.

You will also likely have a fuse that supplies 12 volts DC to your thermostat and HVAC control systems. You said that your AC doesn't show up on the thermostat, but not whether the thermostat is actually powered, or not. Just checking.

Had similar issue
We had somewht the same and disconnected 12v house batteries for a moment and that reset the tstat. Pulling the glass fuse did not do the job.
You can find that thread here from last week.
Hope this helps
