Your thermostat can be set for four time periods (Wake, Leave, Return, and Sleep) for the
weekday schedule (Monday through Friday), and four time periods for the weekend schedule
(Saturday and Sunday). Without additional programming, your thermostat follows the same
preprogrammed schedule for both weekdays and weekends (see Table 1).
The preprogrammed schedule is shown in Table 1. You may keep this schedule or organize your own. Schedules are adjustable as often as you wish. If you decide to keep this schedule, no further programming is necessary.

SYSTEM settings control the thermostat operation as follows:
Fan Setting
To select the desired fan setting, slide the FAN switch in the lower left corner of the themostat.
Emergency Heat
The Emergency Heat feature allows you to Òturn onÓ the electric heat section of the system by moving the system switch to the Em. Ht. position. The indicator flashes and points to Em Ht when the system is in emergency heat mode. The indicator may also point to Aux Ht if the system calls for additional back-up heating.
Auxiliary Heat
The auxiliary heaters assist the heat pump under normal conditions when low outdoor temperature occurs. The indicator points to Aux Ht when the auxiliary heating equipment operates.
Minimum Off-Timing
Your thermostat comes equipped with a minimum off-timer. At certain times during heating or cooling, the system will not start up again for at least five minutes after it turns off (the compressor is off and canÕt be heard). This occurs when you change the SYSTEM switch position while the compressor is off or when you change the temperature setting, causing the compressor to turn off. The minimum off timer is also triggered during a power interruption and power restoration. You will know the minimum off time is in effect by a flashing or on the display.
CAUTION
Equipment Damage Hazard.
Can cause permanent damage to the compressor or other equipment. To avoid possible equipment damage, do not operate the cooling when the outside temperature is below 50°F (10°C). See equipment manufacturer instructions. To avoid possible compressor damage, allow the compressor to remain off for five minutes before restarting.
