THE OPTIMUM COMFORT AND ENERGY SAVINGS SOLUTION s This thermostat is actually a small but powerful computer. When calculating the exact time to turn on your furnace or air conditioner, it considers: (1) air temperature, (2) temperature of the wall and (3) when you want the comfort temperature established. M168 Your new thermostat is so smart, it's almost human. 3 69-0819 s During programmed recovery, the thermostat gradually increases the control temperature and turns the equipment on and off several times to save energy by avoiding overshooting the comfort temperature. You can see the current control temperature anytime during recovery by pressing the PRESENT SETTING key. s This smart control learns from experience. Each day it checks how closely it hit the target and adjusts the recovery start time accordingly. It typically takes four to eight days after installation for this thermostat to adjust to the weather, your life style, home construction and heating/cooling system. The thermostat calculates the LEAVE/RETURN recovery separately from the SLEEP/WAKE recovery. IMPORTANT: With Programmed Recovery, program the times when you want your home comfortable. The thermostat will decide how early to begin the temperature changes. NOTE: Some models will show 32° F instead of the current temperature, indicating the thermostat is operating on backup batteries until the thermostat is mounted on the wallplate and the system is powered. 4 69-0819 System Operating in Comfort Mode AM PM SET PT SUN MON TUE WED THU FRI SAT COOL ON HEAT ON WAKE LEAVE RETURN SLEEP TEMPORARY UNOCCUIPIED TEMPERATURE AM PM SET PT SUN MON TUE WED THU FRI SAT COOL ON HEAT ON WAKE LEAVE RETURN SLEEP TEMPORARY UNOCCUIPIED Recovery Begins AM PM SET PT Recovery Continues System Operating in Energy Savings Mode AM PM SET PT SUN MON TUE WED THU FRI SAT COOL ON HEAT ON WAKE LEAVE RETURN SLEEP TEMPORARY UNOCCUIPIED SUN MON TUE WED THU FRI SAT COOL ON HEAT ON WAKE LEAVE RETURN SLEEP TEMPORARY UNOCCUIPIED ENERGY SAVINGS PERIOD RECOVERY FROM ENERGY SAVINGS COMFORT PERIOD TIME M171 THE THERMOSTAT USES THE SAME SCHEME TO RETURN GRADUALLY TO LOWER COMFORT TEMPERATURE DURING THE COOLING SEASON. 5 69-0819 Programming Your Thermostat The thermostat can be programmed in your hand before it is installed or after it is on the wall if you make sure the batteries are installed. If you need to install or replace the batteries, refer to the Maintaining Your Thermostat section. Your thermostat can be programmed for seven days (separate programs for each day of the week). PROGRAMMING The personal programming chart can be helpful for plannng your program schedule of time and temperature settings for various times of the day. Four time periods are available: MORNING is the time period when you want the zone at a comfortable temperature to begin the day. (This will be a higher temperature during the heating season, or a lower temperature during the cooling season.) This is the only period that must contain a time and temperature for every day. MIDDAY is the time period you can set for an energysaving temperature while the zone is unoccupied. (This will be a lower temperature during the heating season, or a higher temperature during the cooling season.) EVENING is the time period when you want the zone at a comfortable temperature for family activities in the evening. NIGHT is the time period you can set for an energysaving temperature while you are sleeping or the zone is unoccupied. Set it to start at your family's normal bedtime. (For more comfortable sleeping in the cooling season, some people choose not to raise the cooling temperature during the night.) You can set a different schedule for each day of the week because your requirements will probably be different for each day. Fill in the times and temperatures you desire for each day of the week. If you decide not to program the 6 69-0819 thermostat, it will automatically control heating from 6:00 AM to 10:00 PM at 70° F [21° C]. The temperature will be 60° F [16° C] from 10:00 PM to 6:00 AM. Cooling is automatically controlled at 78° F [26° C] 24 hours a day. Also, you do not need to enter a time and temperature program for all periods if your schedule does not require it. For example, a zone that is occupied Monday and Tuesday only requires programs for MORNING and NIGHT.
