DEVICE CONTROL MODULES FOR DEMAND MANAGEMENT SYSTEMS
First Claim
1. A device control module for making a non-demand management system capable electrical device demand responsive to a demand management system, the device control module comprising:
- a relay configured to be electrically connected to a power circuit of the electrical device to control power supply to a load device of the electrical device;
a relay driver operated to open and close the relay; and
a controller operating the relay driver, the controller receiving a demand state signal from the demand management system supplying power to the electrical device, the controller operating the relay driver based on the demand state signal;
wherein the relay is configured to power off the load device of the electrical device irrespective of the main control operation of the electrical device.

Abstract
A device control module for making a non-demand management system capable electrical device demand responsive to a demand management system includes a relay configured to be electrically connected to a power circuit of the electrical device to control power supply to a load device of the electrical device. The device control module includes a relay driver operated to open and close the relay and a controller operating the relay driver. The controller receives a demand state signal from the demand management system supplying power to the electrical device and operates the relay driver based on the demand state signal. The relay is configured to power off the load device of the electrical device irrespective of the main control operation of the electrical device.
