million cycles and will provide years of quiet and
reliable operation.

Ensure that the installation process does not alter the
damper in a way that will cause interference to the blade
moving freely.
CAUTIONS
Use cautions when mounting components to surfaces
that may have concealed wiring beneath the surface.
!
Read and follow all instructions carefully.
Follow all local electrical codes during installation. All
wiring must conform to local and national electrical
codes.
Read entire manual before installing products.
Caution! Direct Damper Controls are not an
alternative to zoning. Installing too many controls on
a single HVAC system could cause airflow and
pressure problems.

using the VP and GND terminals. Up to 6 R80DV Dampers can
be controlled by a single Manual Wall Control.

The R80DV Damper actuator has a Close position limit that can
be used to insure a minimum airflow even when the thermostat
tries to fully close the damper. The minimum Close position can
be set from about 50% closed to fully closed.
This should be used when a large number of R80DV Dampers
are used with the same HVAC system to insure that static
pressure does not damage the ducts.

Slide off the cam cover.
Loosen the set screw and
rotate the close cam counter
clockwise to the desired stop
position. Tighten the set screw
and replace the cam cover.

The damper requires
24VAC power that can
be provided by a 40VA,
24VAC transformer.
40VA transformer can
power 10 dampers. The
transformer can be a
plug-in type or a
transformer mounted on
a junction box in the
ceiling.
