Abstract
A communication system for an appliance is provided. The communication system includes a modular communication device, a clock device, and a controller operably coupled to the modular communication device and the clock device. The modular communication device is operable to communicate with a remote server over a communication and is configured to receive demand response signals from the remote server. The clock device is configured to perform clock estimation operations to estimate a true time for the communication system. The clock device includes a real-time clock chip and a low voltage direct-current (DC) power supply that is configured to supply low voltage power signals to the real-time clock chip based at least in part on an operating condition of the appliance. The controller is configured to operate the appliance based at least in part on the demand response signals received over the communication network.
