A. The Vent Damper is continuously powered at Terminal 1.

B.When there is a call for heat, the damper relay coil is energized through Terminal 5 if all limits ahead of the damper are satisfied.

C.The relay coil closes contacts which energize the damper motor, causing the damper to open.

D.When the damper blade reaches the fully open posi- tion, power is sent back to the ignition circuit through Terminal 2 and the damper motor is de-energized.

E.When the call for heat is satisfied, the damper relay coil

is deenergized - closing contacts which energize the damper motor. This causes the damper to close. When the damper blade reaches the fully closed position, the damper motor is de-energized.

POWER FAILURE - The damper blade will stop in the position it was in when power failed. (Combustion can never take place unless the damper blade is in the fully open position.)
