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 insert a red 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 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.
