NOTE
: Wiring of the ABCD bus only requires a four--wire
connection; however, it is good practice to run thermostat cable
having more than four wires in the event of a damaged or broken
wire during installation.
The following color code is recommended for each ABCD bus
connection:
A
— Green = Data A
B
— Yellow = Data B
C
— White = 24 VAC (Com)
D
— Red = 24VAC (Hot)
It is not mandatory that the above color code be used, but each bus
connection in the system
MUST
be wired consistently.
Step 3 — Install Components
INSTALL Evolution
r
DAMPER CONTROL
The Evolution
r
Damper Control is designed so that wires can enter
it from behind, above, or below. Plan wire routing before mounting
Damper Control.
1. Remove cover to access mounting holes.
2. Mount back plate to wall using screws and wall anchors
provided.
3. Level back plate and tighten screws.
INSTALL MASTER ZONING WALL CONTROL

for details.
NOTE
: Improper wiring of the ABCD connector will cause the
Evolution
r
Zoning System to operate improperly. Check to make
sure all wiring is correct before proceeding with installation or
turning on power.
INSTALL REMOTE ROOM SENSORS
1. Separate the sensor cover and mounting back plate by
squeezing the top and bottom of the cover together firmly
by grasping the raised top and bottom ridges. This will re-
lease the cover. Mount to the wall using the screws and an-
chors provided.
2. Pull a 2--conductor wire through hole on right--hand side.
3. Recommended connection is BLACK to either terminal,
WHITE to remaining terminal (sensor terminals are not
marked for polarity because polarity is not important).
Stranded or common bell wire may be used. Lengths up to
1000 ft. will contribute no noticeable error.
4. Push any extra wire into the wall and seal the hole to pre-
vent air leaks. Align the sensor cover with the base plate,
then press firmly until the cover snaps into place.
INSTALL ZONING SMART SENSOR
See the Evolution
r
Zoning Smart Sensor Installation Instructions
for details.
Step 4 — Install Zone Dampers
Proper selection and sizing of dampers is very important for proper
system operation. Be sure to consult the Damper Product Data
Sheet and Evolution
r
Zoning Design Guide for assistance in
making these selections. Selection and sizing information is not
provided in this installation instruction. Zone dampers are available
in round, rectangular, and slip--in design, and may be installed in
any position. Install the damper so that the actuator is visible for
inspection and accessible in the event it would need to be serviced.
The black mark on the end of the damper shaft represents the
position of the damper blade. To wire the damper, locate the
terminals labeled: OPN (open); COM (common); CLS (closed; and
wire appropriately (see Fig. 1 for Damper 24 VAC connection).

If the duct system requires multiple dampers for a single zone, up
to five dampers (maximum) may be wired in parallel. For all
applications, including retrofit, it is recommended to use only
current dampers with direct--drive style actuators.
DO NOT
use
older damper with crank--arm style actuators.
If an actuator is removed from a damper for any reason, it must be
properly aligned when it is reinstalled. This can be done by
rotating the actuator and the blade to their closed positions and
then tightening the actuator (set screw) to the shaft. This assures
alignment at the closed position. (Pressing the quick blade release
button allows the actuator to be manually turned.)
ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
Condensation can damage the actuator. When dampers are
located in an unconditioned space, condensation is likely to
occur in cooling. To prevent condensation and losses, all
dampers and ductwork in unconditioned space must be
insulated or otherwise protected.
CAUTION
!
Whenever condensation might occur, it is recommended that a
plastic actuator cover (p/n, DAMPACTXXCOV) be used over the
actuator. This cover can help prevent condensation on the actuator
by helping to keep out ambient humidity. Insulation may be
applied over the cover to minimize heat transfer.
To install, place the cover over the actuator and seal it in place over
the surrounding insulation with duct tape on all four sides. Sealing
need not be perfect because there will be positive pressure inside
the cover. Do not mount the dampers with their actuators hanging
directly beneath the ductwork. It is best to mount the actuator
facing in either the three or nine o’clock position.
For specific duct types, follow the instructions below:
NOTE
:
All zone dampers and ductwork must be properly
supported according to local codes or SMACNA standards.
