The user manual doesn't say how to set the thermostat back to factory defaults.

Look for a small hole, perhaps on the back of the unit. Using a paper
clip press the button down for a few seconds. It may or may not apply
to your unit, but check it out. Particularly if you mistakenly changed
the program wrong. It gets you back to the factory defaults after you
messed it up. HTH
