Set AFAM+ System Values

The Controlled Atmosphere (CA) option submenu in the Config menu is factory set to AFAM+. The controller then adds the AFAM, AFAM Delay, AFAM Rate, and CO2 Max submenus to the Controls 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 and gas sensor are connected to the controller.

  • AFAM+: This setting turns on the AFAM+ system to control the CO2 gas level. The controller then adds CO2 Max and AFAM Delay submenus to the Controls menu.

The default setting for AFAM in the Controls menu is the last value set (Off, AFAM, or AFAM+). Controlled Atmosphere (CA) and Fresh Air Vent Man must be set to AFAM+ to control the vent door to the CO2 gas level.
