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 in the AUTO position, the fan is also off. ON--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 plenium 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. Stop switch lever in detent over the desired function indicator mark for proper circuit operation. 9 69-0333--6 Inserting Timer Batteries Power is supplied to the timer by two AAA alkaline batteries (included.) Install batteries in thermostat as shown. See Fig. 2. One 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 M8585 Fig. 2--Inserting timer batteries. 10 69-0333--6 Setting The Timer Lift thermostat flip-up cover to find the 24-hour program dial, slotted in ten-minute increments. Adjust the timer to the current time by carefully turning the knob clockwise . Do not reverse the knob. When time is set correctly, 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 p.m., the time indicator arrow will point directly to the dark band on the dial. For 11 a.m, the arrow will point to the light band on the dial. TIMER SETTING KNOB TIME INDICATOR ARROW M1856 Fig. 3--Setting the timer. Daylight saving time When daylight saving time starts, carefully move the knob clockwise one hour. When daylight-saving time ends, carefully move the knob clockwise 23 hours. Do not reverse the knob, or damage to the timer mechanism may occur. 11 69-0333--6 Programming You can program your thermostat to automatically lower and raise the temperature one or more times every 24 hours. Refer to energy savings chart on the back cover for typical heating and cooling savings with your new thermostat. Before setting your program Lift thermostat flip-up cover to find the 24-hour program dial. The slots on the program dial (Fig. 4) are for the program pins that can be inserted at ten-minute 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 a.m. for high temperature 12 (comfort period); a blue pin is inserted at 10:00 p.m. for low temperature (energy saving period). 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 saving 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 the 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. 69-0333--6 24-HOUR PROGRAM DIAL (GRAY AREA FOR NIGHT SETTINGS) 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. · Decide when you want the energy saving 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 saving setpoint. · You can set both a day and a night program. See Fig. 5 for programming examples.

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 saving 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 saving setpoint.

Fig. 5--Programming examples. 14 69-0333--6 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--moving the program index wheel or pushing the setting levers together. Moving 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. PROGRAM INDEX WHEEL TIME INDICATOR ARROW M1857 15 69-0333--6 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 to the high temperature period, move the wheel from blue to red. The change will be in effect until the next regularly scheduled change. 50 60 70 80 Pushing the setting levers together will hold a particular temperature until you change the levers back. This method is recommended for a long-term absence: · Simply push both levers to the temperature you wish for system control. This temperature will stay in effect until you change the levers back. 50 60 70 80 M2500 16 69-0333--6 Troubleshooting Your Honeywell thermostat requires little or no attention.
