Abstract: An HVAC system includes an HVAC controller and a motor having five taps and a motor controller including a motor memory and a motor processor. The motor memory stores a first set of control data and instructions that cause the motor processor to drive the motor according to the first set of control data in response to energization of one or more of the five taps. The HVAC controller includes an HVAC controller processor and an HVAC controller memory. The HVAC controller processor is programmed to output instructions to the motor on one tap of the five taps, the instructions instructing the motor controller to change at least one element of the first set of control data to create a second set of control data different than the first set of control data.
