To change the leveling you may have to unscrew 2 or 3
recessed screws to remove the thermostat from the baseplate, and loosen
the screws holding the baseplate to the wall. The baseplate has level marks.

Wonderful information.

You've explained items (recessed screws, level marks, etc.) that I could

Thanks for helping me.
