To change the pins or add a new
energy savings period:
• To insert a pin, push it straight into the
selected notch on the program dial until it's
completely seated.
• To remove a pin, press against program dial
and pull the pin straight out. DO NOT attempt
to change a pin if it is engaged with the
program index wheel.
• On heating/cooling systems, you must reset the
pins when the seasons change. You will also
probably want to change the lever positions.
Setting the Heating Program:
Decide when you want the temperature to
reach the comfort level. Find the notch on the
dial that's one-half hour before this time and
red
insert a pin. The half-hour head start gives
the furnace time to heat the house before you
wake up or arrive home.
Decide when you want the energy savings
period to start and insert a
that corresponds to this time. After the blue pin
engages, the furnace will be off until room temp-
erature drops to the energy savings set point.
