Each day can have 2 (Occupied 1, Unoccupied), 3 (Occupied 1, Occupied 2, Unoccupied), or 4 (Occupied 1, Occupied 2, Occupied 3, Unoccupied) time periods. Each occupied time period has a start time, stop time, heating set point, and cooling set point. The unoccupied time period has a heating set point and a cooling set point. The unoccupied time period is active whenever an occupied time period is not active. Fill in Table 1 on page 5 as an aid to programming the daily schedules.
