Abstract: The method is for operating a remotely-controlled switching device of an energy management system. The switching device is mounted in series on a local electrically powered circuit on which are also mounted in series a load and an electronic thermostat. The method includes generating a first pulsed signal for controlling the switching device, the switching device opening and closing the circuit in response to the first signal. The circuit is opened to prevent the load from operating and is closed when operation of the load is allowed. The method includes generating a second pulsed signal for controlling the switching device at least when the circuit is opened by the switching device in response to the first signal. The second signal causes the switching device to temporarily close the opened circuit at given intervals for keeping an internal circuitry of the thermostat energized while still substantially preventing the load from operating.

Abstract: An electrical load controller circuit for controlling power consumption is described. A detection circuit detects the current flowing through a supply line and produces an output signal representative thereof. A comparator circuit compares the output signal with an adjustable reference signal which is indicative of the maximum power to be consumed by loads connected to the supply line. All of the loads are connected to switching circuits, and these are enabled and disabled by signals received from a decade counter which is in turn controlled by inverters and timer circuits whereby loads can be placed in service in a sequential manner. A modulator intermittently controls the time periods that the electrical load is connected to the supply line as well as the ON and OFF periods of the loads for daytime or nighttime operation.
