controller or new software is installed, a controller
auto configuration will detect the AFAM option
when the AFAM door control module is
connected to the controller.
The default setting for the AFAM in the Setpoint
menu is the last value set (Off, Units or Demand).
The AFAM submenu should be set to Units to
control the vent door to the fresh air exchange rate
setting.
WARNING: After installing or servicing
the AFAM door assembly, remove all tools
and install the vent grille before starting
the AFAM system. Failure to replace the
vent grille before turning the AFAM
system on may result in personal injury or
unit damage.
