Abstract
Intermediate connecting devices and electronically commutated (ECM) motors for HVAC systems are disclosed, as well as methods for their use within the HVAC systems. An interface component device coupled to a system controller and an ECM motor may be configured to receive a first and second signal, and convert the voltage across the received signals to a lower-value voltage signal compatible with the ECM motor. The converted voltage signal may be transmitted to the ECM motor to cause the motor to operate in one of a plurality of operation modes. An ECM motor that includes a tap detection circuit and a processor may be configured to receive a voltage signal from the interface component and detect at which input port the voltage signal is received. The ECM motor may select the operation mode for the motor based on the detection of which input port received the voltage signal.
