Automatic Environment Control (AEC-2)

An effective way to automate your ventilation system

The Automatic Environment Control (AEC-2) is a three-stage control that automatically controls the temperature in a room by operating a variable speed fan and up to two single-speed fans or heaters.

To control the temperature, the AEC-2 operates the connected ventilation and heating equipment according to programmed settings. The AEC-2 comes with eight factory-configured operating programs, which can be easily reconfigured for your ideal situation.

The AEC-2 displays alert conditions such as high and low temperatures, power failure, and low line voltage. The AEC-2 has an alarm relay you can connect to an alarm siren, alarm panel, or auto-dialer.

The AEC-2 is ideal for poultry, livestock, greenhouse, or light-industrial buildings.
