The thermostat display shows day, time, program period, and temperature. The thermostat can be set for four time periods per day for weekdays and week-ends.
Before programming the thermostat, you can use the following chart on page 5, to organize your program schedule.
Fill in the times and temperatures you desire for weekdays and weekends. If you decide not to program the thermostat, it will follow the preprogrammed time and temperature settings shown in Table 1.

Table 1. Preprogrammed Time and Temperature Settings.

Period	Time	Heat Setpoint	Cool Setpoint
Wake	6:00 AM	21°C (70°F )	26°C (78°F )
Leave	8:00 AM	17°C (62°F )	29°C (85°F )
Return	6:00 PM	21°C (70°F )	26°C (78°F )
Sleep	10:00PM	17°C (62°F )	28°C (82°F )

Program Schedule

WAKE and RETURN start times should include extra lead time, based on outside temperature and equipment response time, to give your equipment a head start to heat or cool the house. The temperatures cannot be set any higher than 37°C (99°F) or any lower than 4°C (40°F).

Programming
The thermostat is flexible and can be program-med for different schedules for weekdays and weekends, to meet your lifestyle needs. Use the personal Program Schedule for planning your time and temperature settings for various times of the day. See page 5. Four time periods are available during weekdays and weekends —WAKE, LEAVE, RE-TURN, and SLEEP.

• WAKE is the time the thermostat turns on the heating/cooling equipment after an energy saving period. When deciding what time to set for your WAKE period, include extra lead time, depending on the outside temperature and your equipment response time, to give the equipment a head start to heat or cool the house before you get up.(This will be a higher temperature during heating season, and a lower temperature during cooling season.)
• LEAVE is the time period you can set for an energy-saving temperature while you are away at work or school. (This will be a lower temperature during heating season, and a higher temperature during cooling season.)
• RETURN is the time the thermostat turns on the heating/cooling equipment after an energy saving period. When deciding what time to set for your RETURN period, include extra lead time, depending on the outside temperature and your equipment response time, to give the equipment a head start to heat or cool the house before you arrive home.
• SLEEP is the time period you can set for an energy-saving temperature while you are sleeping. (For more comfortable sleeping, some people choose not to raise the cool temperature during the night.)

IMPORTANT Always press the keys with your fingertip or similar blunt tool. Sharp instruments like pens and pencil points can damage the keys.

Minimum Off-Timing

A minimum off-timer in the T8000C assures that the compressor does not come on again for at least five minutes after it turns off. The minimum off-timer is triggered when the compressor turns off and when the SYSTEM switch position is changed. If the compressor turns off when the setpoint is changed, the minimum off-timer is triggered. Power interruption and power restoration also trigger the minimum off-timer. The minimum off-timer operates in cooling on the T8000C. A flashing snowflake indicates the minimum off time is in effect.
