SUMMER WINTER What comfort temperature would you like to maintain? What energy savings temperature would you like to maintain? What time does the first person get up in the morning? Is anyone home all day? What time does the last person leave in the morning? What time does the first person return home in the evening? What time does the last person go to bed? ______ ______ ______ ______ ______ ______ ______ ______ ______ ______ ______ ______ ______ ______ 8 69-0395--2 Setting The Temperature For Heating: Set the left lever (blue mark) to the energy savings temperature you want when you are sleeping or your home is unoccupied. Set the right lever (red mark) to the temperature you want for normal comfort periods. NOTE: You may override the time program by setting both the red and blue levers to the same temperature setpoint. 9 LOW TEMPERATURE SETTING LEVER 50 60 70 80 HIGH TEMPERATURE SETTING LEVER 12 50 60 70 80 3 For Cooling (not applicable on heating-only model): Set the left lever (blue mark) to the temperature you want for normal comfort periods. Set the right lever (red mark) to the energy savings temperature you want when you are sleeping or your home is unoccupied. See Fig. 1. 9 6 M8279 Fig. 1--Setting high and low temperature levers. 69-0395--2 Setting Subbase Switches (if applicable) The subbase system switch controls system operation as follows: HEAT: Heating system is controlled by the thermostat. Cooling system is off. COOL: Cooling system is controlled by the thermostat. Heating system is off. OFF: Both the heating and cooling systems are off. If the fan switch is at the AUTO position, the fan is also off. AUTO: In a cooling only application, only cooling operates. In a heating only application, only heating operates. The subbase fan switch controls fan operation as follows: ON: Fan operates continuously. AUTO: Fan operates with cooling equipment as controlled by the thermostat or with the heating equipment as controlled by the plenum fan switch. In electric heat, heat pump, and fan coil systems, the fan is controlled by the thermostat in heating and cooling. To switch positions, use thumb or index finger to slide lever to desired position. Switch lever must stop in detent over desired function indicator mark for proper circuit operation. 10 69-0395--2 Inserting Clock Batteries Power is supplied to the clock by two AAA alkaline batteries (included). Install batteries in thermostat as shown in Fig. 2. Once a year, or when batteries are dead, replace with two new AAA alkaline batteries. We recommend Energizer® batteries. The thermostat itself will operate without batteries, but will not operate as a fuel saver. BATTERY LOCATION FOR (2) AAA BATTERIES; INSTALL WITH POSITIVE ENDS UP M9619 Fig. 2--Inserting clock batteries. 11 69-0395--2 Setting The Clock Lift thermostat flip-up cover and you'll find the 24-hour program dial, slotted in 10-minute increments. Adjust the clock to the current time by moving the minute hand carefully in the clockwise direction. Do not reverse the minute hand. When time is correctly set, the Time Indicator Arrow (see Fig. 3) will point to the correct time and corresponding daytime (light) or nighttime (dark) band of the program dial. EXAMPLE: For 11 PM, the time indicator arrow will point directly to the dark band. For 11 AM, the arrow will point to the light band on the dial direction one hour. When daylight saving time ends, move the minute hand carefully in a clockwise direction 23 hours. Do not reverse the minute hand, or damage to the clock mechanism may occur.

Refer to the energy savings chart on the back cover for typical heating and cooling savings with your new thermostat. for high temperature (comfort period); a blue pin is inserted at 10:00 PM for low temperature (energy saving period). 24 HOUR PROGRAM DIAL (GRAY AREA FOR NIGHT SETTING) PROGRAM PINS FLIP-UP COVER Before setting your program: Lift thermostat flip-up cover and you'll find the 24-hour program dial. The slots on the program dial (Fig. 4) are for the program pins, which can be inserted at 10-minutes intervals. Three red and three blue program pins are included with your thermostat. The red pins start the high-temperature period; the blue pins start the low-temperature period. A heating program is preprogrammed. A red pin is inserted at 6:00 AM PROGRAM PIN SLOT PROGRAM INDEX WHEEL THERMOSTAT COVER TIME INDICATOR ARROW PROGRAM PIN STORAGE M9614 Fig. 4--Program components. 13 69-0395--2 Two additional sets of pins are located in the program pin storage area. You can set up to six temperature changes with the pins supplied. We recommend at least five hours for each energy saving period. To change the pins or add a new energy savings period-- · To insert a pin, push it straight into the selected notch on the program dial until it is completely seated. · To remove a pin, press against program dial and pull the pin straight out. Do not attempt to change a pin if it is engaged with the program index wheel. · On heating/cooling systems, you must reset the pins when the seasons change. You will also probably want to change the lever positions. Setting the heating program: Decide when you want the temperature to reach the comfort level. Find the notch on the dial that is one-half hour before this time and insert a red pin. The half-hour head start gives the furnace time to heat the house before you wake up or arrive home.

Fig. 5--Programming examples. 14 69-0395--2 Decide when you want the energy savings period to start and insert a blue pin at the notch that corresponds to this time. After the blue pin engages, the furnace will be off until room temperature drops to the energy savings setpoint. You can set both a day and a night program. See Fig. 5 for program examples. Setting the cooling program (not applicable on heating-only model): Decide when you want the temperature to reach the comfort level. Find the notch on the dial that is one-half hour before this time and insert a blue pin. The half-hour head start gives the air conditioner time to cool the house before you wake up or arrive home. Decide when you want the energy savings period to start and insert a red pin at the notch that corresponds to this time. After the red pin engages, the air conditioner will be off until room temperature rises to the energy savings setpoint. 15 69-0395--2 Temporarily changing the program You may temporarily raise or lower the temperature if you come home early, stay up late, plan to be out for the evening, leave on vacation, etc. You can make a temporary change one of two ways--move the program index wheel or push the setting levers together. A move of the program index wheel will change the program just until the next regularly scheduled change is due. · Lift the thermostat cover. · Move the program index wheel counterclockwise so the time indicator arrow points to the desired color on the dial. EXAMPLE: If you are currently at the high temperature period and want to switch to the low temperature period, move the wheel from red to blue. If you are currently at the low temperature period and want to switch 16 to the high temperature period, move the wheel from blue to red. The change will be in effect until the next regularly scheduled change.
