- The Damper works in sync with Broan’s SmartSense® whole-house ventilation
system. When any one or more of the SmartSense® exhaust fans turns on, the
Damper fully opens to allow fresh outdoor air into the home. When no SmartSense®
fans are operating, the Damper closes. SmartSense® utilizes LinkLogic™, so
communications between the fans and the Damper occurs over the home’s power
lines, and no additional control wiring between the Damper and fans is necessary.
6.2 Applications with the Direct-Wired Model (MD*T) model)
 Compatible BEST, NuTone, or Broan Range Hood with Damper

‐ The Damper fully opens or closes based on a direct signal from a compatible
BEST or Broan range hood which is “MD-capable.” This signal is triggered by
the operation of the range hood, which is sent through a hard wired connection
between the two devices using a Broan-supplied transformer. Only those BEST,
NuTone, or Broan range hoods which are MD-capable may be used for this
application.
