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 night program.

See Fig. 5. for program examples.

Setting the Cooling Program

Decide when you want the temperature to

reach the comfort level. Find the notch on the
program dial that’s 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.
