Abstract
An HVAC unit includes an HVAC motor and a system controller. The HVAC motor is coupled to a motor controller. The motor controller is configured to receive a command signal bearing a digitally encoded operating level of the HVAC motor. The system controller is coupled to the motor controller, and is configured to transmit the command signal to the motor controller. The system controller modulates the command signal with the digitally encoded operating level in response to a service demand.
