Operation

A floating control signal controls the damper actuator. The actuator’s
angle of rotation is proportional to the length of time the signal is ap­plied. A 24 Vac control signal to wires 1 and 6 (G-Y1) causes the ac­tuator coupling to rotate clockwise. A 24 Vac control signal to wires 1
and 7 (G-Y2) causes the actuator coupling to rotate counterclockwise.

To reverse the direction of rotation, the wires 6 and 7 (Y1 and Y2)
can be interchanged.

In the event of a power failure or with no control voltage, the damper
actuator holds its position.

Life Expectancy

An improperly tuned loop will cause excessive repositioning that will
shorten the life of the actuator.
