How do I temporarily override the program schedule on the Honeywell 6000?
Press the up or down temperature buttons to immediately adjust the temperature. This temporary override will be maintained only until the next programmed time period begins. For example, if you increase heat in the morning, it will automatically lower when you leave for work. To cancel this temporary setting at any time, press RUN SCHEDULE.
