to the world of energy savings with your new Honeywell thermostat. The Honeywell name is your assurance of accurate control and reliable operation for years to come.
Your new thermostat will automatically lower and raise the temperature in your home one or more times every 24 hours. This allows you to significantly lower your fuel costs, while awaken­ing (or returning home) to a comfortable temperature.

Setting the Temperature
For Heating:
Set the left lever (blue mark) to the energy
saving temperature you want when you are sleeping or your home is unoccupied.
Set the right lever (red mark) to the tempera-
ture 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.
For Cooling:
Set the left lever (blue mark) to the tempera-
ture you want for normal comfort periods.
Set the right lever (red mark) to the energy

Inserting Timer Batteries
Power is supplied to the timer by the 24 Vac transformer, by two AAA alkaline batteries (included), or by the heating or cooling control circuit. Backup batteries may be installed to supply power to the timer if power is interrupted when using a 24 Vac powering method. 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. Properly dispose of old batteries.
