Operating modes
Operating mode CON / VAV - variable air volume control
Variable air volume control (VAV): The operating point is determined by the setpoint
(DC 0…10 V or DC 2…10 V signal at YC input) and the Vmin / Vmax settings.

Operating range
Override control in VAV / VVS mode with Y1 and Y2 inputs
Using the Y1 and Y2 control signals, the damper of the air volume controller can be driven
either to the fully open or fully closed position, overriding the setpoint YC.

Action
VAV control with
DC 0/2…10 V setpoint
DIR r → rotates CW
DIR L → rotates CCW
Damper opens fully
VAV control with
DC 0/2…10 V setpoint
DIR r → rotates CCW
DIR L → rotates CW
Damper closes fully
The actuator can also be driven to "fully closed" by setting Vmin ≤ 0 % and YC = 0 V.
