Before mounting CPO-VAV2A controller
Before mounting the CPO-VAV2A onto the VAV box damper
shaft, do the following:
1. Ensure that the diameter of the damper shaft is within the
allowed limits (round: 8…16 mm, square: 6…13 mm).
2. Ensure that the damper shaft has a length of at least 40
mm.
3. Determine the direction (CW or CCW) in which the damper
shaft rotates to open the damper. The installation
procedure varies depending on the damper direction.
4. Determine the angle of the damper opening (can be
adjusted in increments of 5.5°).
If damper rotates CW to open
If the damper rotates clockwise (CW) to open, mount the
CPO-VAV2A as follows:
1. Manually open the damper.
2. Push down the declutch button of the CPO-VAV2A, and
while holding it down, manually rotate its shaft adapter fully
to the clockwise position.
3. Mount the CPO-VAV2A to the VAV box damper shaft.
4. Set the mechanical end limits of the CPO-VAV2A (see
Figure 2 on page 3 ). When the CPO-VAV2A closes, the
damper will thus rotate
5. CCW until the mechanical end limits are reached.
If Damper Rotates CCW to Open
If the damper rotates counterclockwise (CCW) to open, mount
the CPO-VAV2A as follows:
1. Manually open the damper.
2. Push the declutch button of the CPO-VAV2A, and while
holding it down, manually rotate its shaft adapter fully to
the counterclockwise position.
3. Mount the CPO-VAV2A to the VAV box damper shaft.
4. Set the mechanical end limits of the CPO-VAV2A (see
Figure 2). When the CPO-VAV2A closes, the damper will
