|MOUNTING
Mount the Smart Damper.
To minimize air noise, the Damper should
be installed as near to the trunk line as is reasonable. Install the
damper whatever direction is convenient. Be sure that the Smart
Node
is easily accessible as you will need access to it. Each end of the
damper should be secured using at least three screws spaced evenly
around the circumference. Flex duct can be secured using a zip tie.
|WIRING
Powering the Smart Damper Smart Node.
Using the correct polarity,
plug the 24VAC 18/2AWG coming from either the transformer or from
the previous Smart Node of a different zone. Color code so that red is
always in the ~ port. Strip back 18/2AWG wire ~1/2” and insert until
wire is locked in place.

Wiring the Smart Damper(s).
Plug the RJ 45 harness on the primary
damper into the Damper 1 port on the Smart Node. If there is a
second damper, use the 20’ RJ45 male to female extension cable to
plug the secondary damper into the Damper 2 port on the Smart
Node.
If there are more zones keep running your bus line to each primary
damper securing cables so that there is no excessive strain on any
connection points.
