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 set

point.

Setting the Cooling Program

Decide when you want the temperature to

reach the comfort level. Find the notch on the

program 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.
