Blower Control

When the system is in the automatic mode, the automatic temperature control (ATC) module determines the blower speed required from a comfort algorithm. When the system is in the manual mode, the automatic temperature control (ATC) module operates the blower at the speed selected using either the rotary control switch on the integrated control panel or the + and - soft buttons on the touch screen display (TSD). The automatic temperature control (ATC) module also adjusts blower speed to compensate for the ram effect on inlet air produced by forward movement of the vehicle. As vehicle speed and ram effect increases, blower motor speed is reduced, and vice versa.
