DAMPER LINKLOGIC™
CONTROL LINK INSTRUCTIONS
1. LinkLogic™ devices communicate via the power line. A phase
coupler is required if LinkLogic™ damper control and master de-
vice (such as LinkLogic™ enabled range hood or SmartSense
control) are wired to opposite electrical phases.
2. Make sure power is applied to LinkLogic™ damper control and
master device.
3. Start master device link process per its installation instructions.

4. When instructed, using a small screwdriver or paperclip, press
SET button for 3-seconds to activate damper control's link
mode.
5. After exiting master device link mode, turn master device on
and off and check damper control on and off accordingly.
After link is established, damper control will remain in its initial
state until master device is turned on and off.
Damper control's LED is on when damper is open and off when
damper is closed.
6. If LinkLogic™ enabled range hood does not cause damper
control to turn on and off, check that PLM (power-line modem)
jumpers are properly installed. Refer to range hood and PLM
installation instructions.
A qualified HVAC contractor should also ensure the proper
operation and venting of all combustion equipment in the home.
7. LinkLogic™ damper control can be linked to multiple master
devices. If damper control is not turning off with newly linked
master device, make sure another device is not on, which would
cause the damper to remain on (open).
8. In order to erase damper control links and return it to factory
default state, proceed as follows.
a. Remove power from damper control.
b. Press and hold SET button for 10-seconds (LED may light
when SET button is pressed and then dim to off).
c. Continue holding SET button and turn power on.
d. LED should be on when SET button is pressed and power
is applied.
e. After 3-seconds, release SET button.
f. After 3-seconds, LED should light.
g. If LED does not light, repeat this process.

MAINTENANCE

Regular maintenance is necessary to ensure the proper operation
of the Damper system. Failure to conduct such routine maintenance
can jeopardize the ability of the Damper to introduce fresh air into
the home. Regular maintenance should include the following
activities:
®
• Clean the outside bird screen to ensure it is free from debris
and open to allow fresh air to enter.
• Clean or replace the interior filter(s) which serve to filter fresh air
before it enters the home.
• Maintain a clear opening at the outdoor end cap, which means
preventing the buildup of snow, leaves, or vegetation at the end
cap.
• During regular HVAC maintenance, have the mechanical
contractor inspect the Damper system for proper operation.
