[. . . ] To set times as you program the cooling temperatures, use the TIME AHEAD and BACK keys as described in Step 2. First program the WAKE temperature for weekdays. WAKE Press and release. The display shows WAKE and the time and temperature you programmed for heating. AM SUN WAKE HEAT SET PT SET HEAT/COOL Press and release so COOL shows on the display, along with the preprogrammed cooling temperature. AM SUN WAKE COOL SET PT DAY If display reads SAT or SUN, press and hold until MON TUE WED THU FRI appears. AM MON TUE WED THU FRI WAKE COOL SET PT 15 WARMER COOLER Press and hold until the display shows the desired temperature. If the display blinks while you hold down TEMPERATURE WARMER or COOLER, you have reached the setting limit. If your thermostat can switch automatically between heating and cooling, the cooling temperature must be at least 2 degrees higher than the corresponding heating temperature. For example, if the heating setting is 21° C, the minimum cooling setting is 23° C. If you desire a lower cooling setting, the heating setting must first be lowered accordingly. AM MON TUE WED THU FRI WAKE COOL SET PT 16 PROGRAMMING YOUR THERMOSTAT Program the LEAVE temperature, if desired. LEAVE Press and release. Use for improved air circulation during special occasions or for more efficient electronic air cleaning. In winter, the fan on most systems starts a few minutes after the furnace comes on. The fan starts and stops with the furnace in some electric heat systems. FAN ON AUTO FAN ON AUTO 21 Then set the system switch. HEAT: The thermostat controls your heating system. AUTO: The thermostat controls either your heating or air conditioning system, depending on room temperature. Energy-saving temperature The lower (heating) or higher (cooling) temperature that lets you save on heating and cooling costs when you're asleep or away. Program The times and temperatures you set to define the comfort and energy savings periods for each schedule (weekdays, Saturday, Sunday). Programmed Recovery Recovery automatically starts early enough so your house is at the comfort setting by the time you've chosen. The thermostat turns the heating or cooling equipment on and off to maintain this temperature at the thermostat location until another temperature setting goes into effect. Setup Raising the temperature in the house for a set period every day in summer for energy savings. The higher temperature is the energy saving temperature. 35 Period key One of the four keys--WAKE, LEAVE, RETURN, or SLEEP--that you press to check or program the start time and temperature for a time period. Preprogrammed schedule This is the schedule programmed into your thermostat at the factory. It sets a night program that provides energy savings if you don't set your own program, or if your personal program is lost for any reason. The program, which is the same for all days of the week, is: Period WAKE LEAVE RETURN SLEEP Start Time 6:00 AM - - - - - - No - - - - - - No 10:00 PM Temperature Heating Cooling 21° C 26° C program - - - - - - - program - - - - - - - 16° C 26° C Recovery The time when the thermostat operates the heating or air conditioning equipment to return the house from the energy savings to the comfort temperature. If thermostat is set for Programmed Recovery, the thermostat starts the recovery period early so the house will be at the comfort setting by the time you've chosen. Saturday program schedule The schedule of WAKE, LEAVE, RETURN and SLEEP period start times and temperatures that you program to run on Saturdays. [. . . ] The temperature displayed on the thermostat doesn't always match the room temperature on another thermostat located right next to it. Can I control when the furnace comes on in the morning? Remember, whichever way you set your thermostat, if it is so cold outside that your house drops to your sleep temperature, the furnace will turn on and off at night to control the temperature at that setting. It bypasses all program settings and holds the temperature at the present setting. To increase or decrease the temperature while on HOLD, use the WARMER-COOLER keys. [. . . ]
