Abstract:
An air recirculation control system is basically provided with a thermal sensing arrangement, a blower speed sensing arrangement, a recirculation door actuator and a control device. The thermal sensing arrangement detects a prescribed temperature condition. The blower speed sensing arrangement provides a prescribed blower signal indicative of a prescribed blower speed condition. The recirculation door actuator operates a recirculation door. The control device selectively activates the recirculation door actuator to switch between a normal air intake mode and a recirculation override mode based on the prescribed temperature condition detected by the thermal sensing arrangement and the prescribed blower signal received from the blower speed sensing arrangement.
