Planning Program Schedule
The thermostat display shows the day, time, program period, and temperature. The thermostat can be set for four-time periods per day for weekdays and weekends. Before programming the thermostat, you can use the program schedule to plan your program. Fill in the weekday and weekend times and temperatures you desire. If you decide not to program the thermostat, it uses the preprogrammed time and temperature settings in Table

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 99°F (37°C) or any lower than 40°F (4°C).

Programming Thermostat

The thermostat is flexible and can be programmed for different schedules for weekdays and the weekend to meet your lifestyle needs. Use the personal Program Schedule for planning your time and temperature settings for various times of the day. Four time periods are available during weekdays and the weekend—Wake, Leave, Return, 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, including 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 the heating season, and a lower temperature during the cooling season.) Leave is the time period you can set for an the energy-saving temperature while you are away at work or school. (This will be a lower temperature during the heating season, and a higher temperature during the 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, including 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.)

Operating Thermostat

Setting SYSTEM and FAN Switches
Use the SYSTEM and FAN switches to control thermostat operation. SYSTEM settings: Cool: The thermostat controls the cooling. Off: Both the heating and cooling are off. Heat: The thermostat controls the heating. Em. Ht. (heat pump models only): The thermostat cycles emergency heat relay (E) and cycles auxiliary heat (W2), as needed, to maintain setpoint. Terminal L is energized continuously (fault heat relay is
on continuously). The compressor is de-energized. Slide the SYSTEM switch in the lower right corner of the thermostat to select the desired system setting. FAN settings: Auto: Fan operates with equipment. On: Fan operates continuously. Slide the FAN switch in the lower-left corner of the thermostat to select the desired fan setting.

Heat and Cool Indicators
Indicates a call for heat. Indicates a call for cool.
NOTE: In the programming mode, the and indicate the system setting.

Back Lighting (Select Models)
Any key pressed lights the display for approximately ten seconds.

Replacing the Batteries (T8002 Models Only)
The T8002 Thermostat requires three AA alkaline batteries to operate. As the batteries run low, your thermostat shows a “bAt Lo” message in the digital display. The message flashes for one to two months before the batteries run out completely. Replace the batteries as soon as possible after the message flashes. The batteries are located on the right side of the thermostat. Open the battery door from the bottom, lifting out.
If you insert the batteries within approximately 30 seconds of removing the old batteries, the thermostat retains the current time and day. If the display is blank when changing batteries, reset the time and day. Your program does not require resetting; it is stored permanently! Important: Even if you do not see the “bAt Lo” message, replace the batteries once a year to prevent leakage and/or the heating/cooling
system from shutting down due to a lack of battery power.

Minimum Off-Timing
The thermostat minimum off-timer 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 T8000 and T8001, T8002, and T8024 (multistage model) and in first-stage heating or cooling on the T8011 (heat pump model). A flashing flame or snowflake indicates the minimum off-time is in effect.

Troubleshooting
