This thermostat is a sealed unit. It does not need to be leveled. No exposed parts when the cover is removed. I will try to get the model number and post it. It is a rectangular unit,, not one of the old round thermostats.
As for the anticipator,,,,,,,,,,,,,,,,, not sure what that is.
It is on an outside wall, but the wall is insulated, and I even insulated the electrical box the thermostat is in. I thought with it being on an outside wall, that that might have something to do with it, but it didn't make a difference. The garage has no partitions, so and outside wall is all I have to work with at the time. I may be able to mount it remote to see if it makes a difference.
thanks,,
