Abstract
A method of operating an HVAC system including a motor having five taps, and an HVAC controller communicatively connected to a plurality of the five taps the motor includes storing, by a processor of the HVAC controller, selected speeds associated with a plurality of operating conditions in a memory of the HVAC control. The processor controls the motor according to the selected speeds and their associated operating conditions using a group of taps of the plurality of taps of the motor to which the HVAC controller is communicatively connected. Data is communicated between the motor and the HVAC controller using one of the plurality of taps of the motor to which the HVAC controller is communicatively connected.
Claims17
An HVAC system comprising:
- a motor having five taps and a motor controller to drive the motor based on simultaneous energization of one or more of the five taps;
- and
- an HVAC controller, the HVAC controller connected to a plurality of the five taps and configured to control the motor based on a plurality of operating conditions, the HVAC controller including a processor and a memory, wherein the processor is programmed to:
- store selected speeds associated with the plurality of operating conditions in the memory of the HVAC controller, wherein the selected speeds comprise more speeds than a number of taps in the plurality of the five taps;
- control the motor according to the selected speeds and the associated operating conditions by simultaneously energizing two or more taps of a group of taps of the plurality of the five taps of the motor;
- and
- receive data communicated from the motor to the HVAC controller on one of the plurality of the five taps of the motor.
