Model WRCD Remote Control Damper
About the WRCD Damper
The WRCD damper is a variable position damper that is adjusted by using the WRC Wireless Remote Control.
It has an under-sized diameter that allows it to slip into the collar of a ceiling diffuser or grill. The WRCD can
increase comfort by regulating airflow into a given area to eliminate over-cooling and over-heating, or it can
save energy by reducing airflow to vacant spaces.
1. Adjust the Minimum Flow
Damper Bypass
The WRCD damper motor has a Minimum
Flow Position Limit that can be used to ensure
some air passage when the WRCD damper is
closed. The Minimum flow position can be set
from about 50% open to fully closed.

2. Install the damper in the ductwork
Remove the flex-duct from the ceiling
register or diffuser collar.
3. Connect the damper to a 24 volt AC power supply
Connect the damper motor terminals as shown. Before leaving the
damper installation location, program the zone number and address
number as explained in step 4.
Damper motors are rated
3.5VA and 130 miliamps dur-
ing operation; 2.25VA and 90
miliamps when idle.

Adjusting the Minimum Flow Position Limit
Set the damper to the fully open position by applying 24VAC across
the COM and 24VAC damper motor terminals. The damper will
cycle open-close-open to calibrate itself. Loosen the set screw and
rotate the Minimum Flow Cam clockwise to increase the airflow for
the damper when it is minimized. The fully clockwise position is
50% open and the fully counterclockwise is 0% open (fully closed).
After adjustment remove and connect power to allow the damper
to re-calibrate itself.
Insert the damper into the collar and
secure it with sheet metal screws.
Attach the flex-duct to the damper and
secure the inner sleeve to the damper
using the cable tie provided.

Alternately you can shorten the inner
sleeve by the length of the damper
and slide the outer insulation over
the damper and secure it with duct
tape. Cut a slot in the insulation to
fully expose the actuator.
