Reviewing Your Family Schedule Write the answers to the following questions in the spaces provided to determine the program that fits your family schedule. 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 times does the last person leave in the morning?
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. See Fig. 1. Set the right lever (red mark) to the tem- perature you want for normal comfort periods. NOTE: You may bypass the time program by setting both the red and blue levers to the same temperature setpoint.
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.
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®...

24-HOUR PROGRAM DIAL (GRAY AREA FOR NIGHT SETTINGS) FLIP-UP COVER PROGRAM PINS THERMOSTAT COVER PROGRAM PIN SLOT PROGRAM INDEX WHEEL TIME INDICATOR ARROW Fig. 4—Program components. 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.
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.
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 counter- clockwise 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 to the high temperature period, move the wheel from blue to red.
Troubleshooting Your Honeywell thermostat requires little or no attention. Most problems can generally be traced to the following: Problem No heat. — system switch. May be in OFF or COOL position. — fuse or circuit breaker. — furnace power switch. May be off.
Temperature change — programs pins for correct time occurs at the wrong locations. time. Room temperatures — positions of thermostat setpoint are not correct. levers. — position of subbase system switch. Check Contact a qualified service technician for assistance.
HEAT position. — fuse or circuit breaker. — condensor switch position. Located outdoors and may be turned off. — Y, G, RC thermostat connections. Check Increase anticipator setting by 0.05 Observe heating system operation. Decrease anticipator setting by 0.05. Observe heating system operation.
Replace with two new AAA alkaline batteries as shown on page 10. Reinstall thermostat wallplate or subbase. Use a spirit level. Thermostat should be about 5 ft [1.5m] above floor on an inside wall. Contact qualified service technician for change of location.
System on-length adjustment NOTE: Not applicable on CT1503 Millivolt Heat model. If the thermostat seems to cycle the heating system too fast or too slow, adjust the heating system on-length by moving the anticipator setting lever one indicator mark at a time (Fig. 6);...
