Understanding program schedules

The daily schedule is split into four events

WAKE: temperature you would prefer to wake up to.
LEAVE: temperature when you are away from the house.
RETURN: temperature you would prefer to return home to.
SLEEP: temperature you would prefer while sleeping.

The times shown in the table below are the defaults. The start time and temperature of each section can be changed to fit your schedule. (See Changing Program Schedules section on pages 15-16.) This thermostat is pre-set to use the following program settings recommended by the Department of Energy (see table below). These settings are intended to reduce your heating/cooling expenses. The fan program is pre-set to AUTO for all events.

Event designator	Start time	Set temperature		fan
Event designator	Start time	Heat	Cool	fan
WAKE	6:00 AM	70°F (21°C)	78°F (26°C)	AUTO
LEAVE	8:00 AM	62°F (17°C)	85°F (29°C)	AUTO
RETURN	5:00 PM	70°F (21°C)	78°F (26°C)	AUTO
SLEEP	10:00 PM	62°F (17°C)	82°F (28°C)	AUTO

Optionally, the thermostat can be set to a two-event or commercial schedule. (See Setup Menu).

Event designator	Start time	Set temperature		fan
Event designator	Start time	Heat	Cool	fan
wAkE/oCCUPiED	6:00AM	70°F (21°C)	78°F (26°C)	AUTO
LEAVE/UNoCCUPiED	10:00PM	62°F (17°C)	82°F (28°C)	AUTO

Progressive recovery

The Progressive Recovery feature allows the thermostat to activate the heating and cooling equipment prior to an event in order to reach the desired temperature at the start of the next scheduled event.

Example: If the WAKE time is 6 am, and the set temperature is 70°, the heat will come on before 6 am, so the temperature is 70° by the time you wake at 6 am.
