1. Determine whether the damper blades will rotate clockwise or
counterclockwise to open. See Figure 3.
2. If the blades will rotate counterclockwise, slide the manual override
switch to manual, and move the adjustment lever to the right.
Return the switch to automatic. See Figure 17.
To mount a (modulating) DA-088N024Pxxxx, set the Dual In-line
Package (DIP) switches to the required positions.
1. To access the DIP switches, raise the tab on the lower left side of
the actuator. See Figure 3. The factory setting is clockwise (middle
switch), with a direct-acting feedback signal (right switch).
2. Close the tab over the DIP switches.
To mount a (3-positon) DA-088N024Fxxxx for counter-clockwise
rotation, follow the Counterclockwise Damper Rotation instructions
located in the Wiring Diagrams section when wiring the actuator to the
controller.
