You can reset the override itself or you can reset the thermostat to the original factory settings. I have the 420 manual here which is virually the same.

The resetting of the override timer on page 11.2
To reset the whole thermostat to factory settings, this is found on page 18.2.

Do you need the manual I am refencing?
