AFAM System & AFAM+
Advanced Fresh Air
Management (AFAM) System
An advanced microprocessor controlled fresh air
management system provides programmable
control of the air exchange rate, programmable
delayed vent opening, automatic closure of the air
exchange vent during low ambient conditions, and
data logging of the air exchange rate and vent
opening delay interval.
The AFAM system includes a door control
module, vent door and vent grille. The MP-3000
controller sends a communication signal to the
door control module to position to vent door to the
desired position. The controller can also be set to
delay opening of the fresh air vent for up to 72
hours, in 1 hour increments. This allows faster
product temperature pull-down.
The system is precalibrated for air exchange rates
of 0 to 280 m
3
/hr. (0 to 165 ft
3
/min.). The actual
door position is based on the air exchange setting
and the power supply frequency (Hertz).
If the controller identifies a component failure
during unit startup, an alarm is recorded in the
controller display and data-logger memory. If a
power loss occurs after the AFAM system is
turned on, the controller automatically operates
the vent door based on the previous AFAM Delay
and AFAM Rate settings when power is restored.
Setting AFAM System Values
The AFAM option submenu in the Configuration
menu is factory set to AFAM. The controller then
adds the AFAM, AFAM Delay and AFAM Rate
submenus to the Setpoint menu. If a replacement
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.
