Patent ID: 8362725

Claim:
An interface module for coupling at least one of a thermostat and a system controller to an electric motor, the interface module comprising: a first set of input terminals configured to receive an input signal from at least one of the thermostat and the system controller, the first set of input terminals comprising at least one thermostat input terminal and at least one system controller input terminal, wherein the at least one thermostat input terminal is configured to receive signal-level voltage signals from the thermostat and the at least one system controller input terminal is configured to receive, from the system controller, higher voltage signals than the signal-level voltage signals; control circuitry coupled to the first set of input terminals and configured to generate an output signal based at least partially on the input signal that corresponds to one of a plurality of motor profiles stored within a memory of the electric motor, wherein control circuitry is configured to generate the output signal based on at least one of the signal-level voltage signals and the higher voltage signals; and a first set of output terminals coupled to the control circuitry and configured to be coupled to input terminals of the electric motor and to provide the output signal to the electric motor.
