Abstract
A motor control system for heating, ventilation, and air conditioning (HVAC) applications is described. The motor control system includes a thermostat and an electronically commutated motor (ECM) coupled to the thermostat. The ECM is configured to retrofit an existing non-ECM electric motor included in an HVAC application and to operate in one of a plurality of HVAC modes. The HVAC modes include at least one of a heating mode, a cooling mode, and a continuous fan mode. The HVAC mode is determined based at least partially on outputs provided by the thermostat.

27. A motor control system for heating, ventilation, and air conditioning (HVAC) applications, said motor control system comprising:
-
a motor; control circuitry coupled to said motor, said control circuitry configured to determine a motor operating profile at which the motor operates based on a selected mode of operation; and an interface module coupled to said control circuitry, said interface module configured to be electronically connected to a first device and a second device and further configured to provide said control circuitry with the selected mode of operation based on at least one of a first voltage signal received from the first device and a second voltage signal received from the second device. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A motor control system for heating, ventilation, and air conditioning (HVAC) applications, said motor control system comprising:
-
a motor; and control circuitry coupled to said motor, said control circuitry configured to; receive at least one of a first voltage signal from a first device and a second voltage signal from a second device, the second voltage signal being different than the first voltage signal; and determine which motor operating profile at which said motor operates based at least in part on the at least one of the first voltage signal and the second voltage signal.
