Step 3. Install Modulating Damper
1)
Install a modulating damper in the trunk line supplying air to
the space. Up to four dampers can be connected to define a
zone.
2)
Plug one end of the Plug&Play cable into the "IN" connector
on the damper actuator and the other end into the Zone 1
connector on the DDC2 Damper Control.

Using Multiple Dampers to Define a Zone
If needed, up to 4 dampers can be connected together to
define the space.

Step 4. Apply Power
Turn on power to the HVAC equipment. Observe a green LED on
the DDC2 circuit board and a green LED on the damper actuator.
Step 5. Mount the WLDC Wall Control
The WLDC Damper Control can be mounted on any wall about
5' off the ground (typical thermostat height) using the hardware
kit included.

Step 6. Power the WLDC Damper Control
Install the CR2450 Coin Cell Battery included in the kit.
Press and hold in the areas
indicated near the top of the
control to release the cover.
Replace cover by lining up the plastic tabs on the wall base to
the grooves on the bottom of the cover then snap into place.
Testing Airflow
At the thermostat, activate a heating or cooling call. Set airflow
to 100%. Measure or feel the airflow going to the space as a
reference. Now rotate the knob on the WLDC fully counter
clockwise to 0% to reduce airflow. Within about 15 seconds the
LED on the WLDC will blink green after a successful
communication. You should measure or feel very little airflow.
Now rotate the knob clockwise to 50%. Measure or feel the
airflow going to the space. You should feel more airflow but not
as much as at 100%. If not, see troubleshooting. If the LED does
not blink green, see Troubleshooting.
Troubleshooting
LED does not blink
Make sure the battery is installed correctly. Also an indicator
of low battery.
LED only blinks red
Make sure the DDC2 Damper Control is powered - green
LED on. Also make sure the WLDC and DDC2 are within
range - about 100' within the home. To see the LED on the
DDC2, you may need to remove the cover.
Also, make sure the ID # on the WLDC is matching the ID #
on the DDC2. The ID numbers can be found on the ID
labels on the circuit boards.
