Auxiliary Medium Blower Speeds

When the Medium blower speed is selected, the auxiliary blower motor switch applies a ground for the auxiliary blower motor. Voltage is routed from the auxiliary blower motor, through the high blower motor control circuit, through 2 series resistors in the auxiliary blower motor resistor assembly to achieve the desired auxiliary blower speed. The circuit is grounded by the medium 1 blower motor control circuit, auxiliary blower motor switch and ground circuit. When the Medium High blower speed is selected, the auxiliary blower motor switch applies a ground for the auxiliary blower motor. Voltage is routed from the auxiliary blower motor, through the high blower motor control circuit, through a resistor in the auxiliary blower motor resistor assembly to achieve the desired auxiliary blower speed. The circuit is grounded by the medium 2 blower motor control circuit, auxiliary blower motor switch and ground circuit.
