If the OCC-CONFIG is set to Schedule, the internal schedule commands the LOCAL-OCC object, which sets the Occupancy Schedule command. Note: If you do not have a schedule in the Schedule object and you have the OCC-CONFIG set to Schedule, you can control the unit with the LOCAL-OCC object externally; however, we do not recommend this method. See Table 9 for scheduling information.
5. Select the days to which the schedule should apply. Note that if events are already set for the selected days, they appear in the corresponding event box. If any events conflict between selected days, an asterisk appears in the event box. See Figure 23. 6. Select the Occupancy Status icon for the event. See Figure 24. IMPORTANT: Internally, the TEC3000 uses a BACnet schedule where daily schedules are independent of the previous and next days.
Note: If you do not select Save at this point, the event is not saved and you must repeat the event selection sequence. Figure 26: Saving the event 10. Select Event 2. See Figure 27. The screen resets to the Event 2 Set Schedule screen. The days are preselected to match Event 1. 11. Select the Occupancy Status button for Event 2.

Enabling optimal start The TEC supports an advanced optimal start algorithm. The algorithm works in conjunction with a local schedule to pre-heat or pre-cool the zone before scheduled occupancy periods begin, in order to bring the zone to the desired occupied setpoint when the scheduled occupancy period begins. Occupant comfort is ensured while automatically minimizing energy usage.
