Heater Blower Operation

Manual operation

When the blower speed is set to a certain level using the blower control SW, the A/C control assembly sends signals to the blower control to control the blower motor speed.

Auto operation

When the auto SW is pushed, the A/C control assembly calculates the necessary blower speed from the SW settings and data received from the sensors and automatically sends signals to the blower control to control the blower motor speed.
