Programming You can program your thermostat to automatically lower and raise the temperature one or more times every 24 hours. 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 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 has been preprogrammed. A red pin is inserted at 6:00 AM for high temperature (comfort period); a blue pin is inserted at 10:00 PM 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. 24-HOUR PROGRAM DIAL (GRAY AREA FOR NIGHT SETTINGS) FLIP-UP COVER PROGRAM PINS THERMOSTAT COVER PROGRAM PIN SLOT PROGRAM INDEX WHEEL MANUAL PROGRAM ADVANCE BUTTON PROGRAM PIN STORAGE TIME INDICATOR ARROW M8692 Fig. 4-Program components. 69-0574-2 10
