Programming Heating and Cooling Schedule

IMPORTANT
Keep in mind that the up and down keys change the flashing number or
word. When multiple items are flashing, changes affect only one of the
items.
The thermostat can control up to four different schedule periods per day:
• Occupied1–Work arrival time. Period to keep space at a comfortable
temperature.
• Unocc1–Work exit time. Period to keep space at an energy-saving temperature.
• Occupied2–Second occupied period.
• Unocc2–Second unoccupied period.
NOTES:
• Available schedule times are at 15-minute intervals.
• With default settings, all four periods can be programmed. This can be
changed to allow only Occupied1 and Unocc1 programs. To use only
Occupied1 and Unocc1, see Step 8 in the Advanced Settings section.
