more, Air Conditioning Dampers or Fresh Air dampers. Move the switch to instantly power the
damper(s) Open or Closed. Can be used with most Power Open/Power Close type dampers. Can
also be used on Power Open/Spring Close type dampers.

cannot be wired in parallel. A Green LED will illuminate when the switch is in the OPEN position.
