Installation
This document provides the information needed to install
CPO-VAV2A controller. It describes the dimensions, mounting
details and the terminal connections to these devices.
Safety instructions
• When performing any work (installation, mounting, startup), all instructions given by the manufacturer and in
particular the safety instructions provided in this document
are to be observed.
• The CPO-VAV2A controller must be installed and mounted
only by authorized and trained personnel.
• If the unit is modified in any way, except by the
manufacturer, all warranties concerning operation and
safety become invalid.
• Make sure that applicable local standards and regulations
are observed at all times.
• Use only Honeywell supplied or approved accessories.
• Before the system is dismantled, disconnect the power
supply by either removing the power terminal block from
the controller, or by means of local isolation. Read the
following caution note carefully.
Caution
Disconnect the power supply before you start to install the CPO-VAV2A controller. Do not reconnect the power supply until you have completed the installation.

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

Caution
Round ductwork installation is not applicable for America and Canada without appropriate enclosure.

Mounting Caution
Use the anti-rotation bracket and screws included in the unit
pack to mount the CPO-VAV2A. DO NOT use the single screw
to mount the CPO-VAV2A.

Mounting the CPO-VAV2A unevenly with damper housing can
damage actuator. Mount the actuator flush with the damper
housing or add a spacer between the anti-rotation bracket and
the VAV box damper housing.

Serial Number Label
There is a separate label with product serial number in the unit
pack. The user can choose to paste this label on the front of
housing to easily check the product serial number.

Air Flow Pick-up
Connect the air flow pick-up to the two connectors on the
CPO-VAV2A. See Figure 11. Connect the high pressure or
upstream tube to the air flow pick-up connector labeled (H)
and the low-pressure or downstream tube to the connector
labeled (L).

Best practice for zero calibration of air flow sensor
The controller must be powered up for a minimum of 1 hour
before performing the zero calibration for the air flow sensor.

data on MS/TP bus
Controllers with Automatic MAC addressing functionality can
be identified by a label covering the MAC address rotary
switches. This information is also printed on the product label
available on the controller. When a controller with Automatic
MAC addressing feature is powered ON, can assign its own
unique MAC address ranging from 1 to 30. It can also coexist
with other unitary controllers whose MAC addresses are set
manually. The controller can automatically adjust the MAC
address at any time to avoid duplicate addresses in the
network. The automatic MAC address assigned through this
process is retained when the controller is powered OFF.
To disable Automatic MAC addressing, remove th e label on
the rotary switches and set the switches to the manual
