Ducting Requirements & Mode of Operation

Ventilation Mode

In ventilation mode, both motors are running and air is being exchanged with the outside through the supply and exhaust ducts.

Recirculation Mode

In recirculation mode the supply motor continues to run and a damper moves to block off air entering from outside, drawing air instead from the conditioned space. The exhaust to outside motor is OFF when in recirculation mode.

*NOTE: "Defrost" light is illuminated during "Recirculation Mode", indicating damper direction.

Defrost Mode

In defrost mode both the supply and exhaust motors run to draw air through the heat exchange cores. This mode is automatic and does not require field adjustments. Defrost light on side of cabinet illuminates to indicate defrost operation.
