Functional description

The actuator moves a damper blade or a damper blade mechanism to the minimum or maximum position.

Minimum and maximum positions can be set on potentiometers or using mechanical stops.

1-wire control or 2-wire control (3-point) can be used.

1-wire control is actually an open/close control or min/max control.
