Patent ID: 8870087

Claim:
An environmental control device comprising: a temperature sensor; an audio module; an input/out module operatively connected to an environmental system; a memory module; a processor in communication with the temperature sensor, the audio module, the input/out module and the memory module, wherein the memory module stores a control routine comprising processor executable instructions and a user-selected audio file associated with a predefined event related to the environmental system, the processor executable instructions configured to: receive a control indication corresponding to a temperature sensor signal from the temperature sensor, an environmental system output signal from the input/output module, or an input from a user via the environmental control device; determine whether the control indication corresponds to the predefined event; and generate, via the audio module, an audible signal based on the user-selected audio file in response to determining that the control indication corresponds to the predefined event, the predefined event being an input of a setpoint change greater than a predetermined setpoint change from the user via the environmental control device.
