Method and apparatus for electrical load control network
The methods and apparatus described enable automatic configuration, or commissioning, of controller devices and load control devices through a low voltage communication network controlled by one or more controller devices. These methods and apparatus further enable expansion of the load control system by connection of additional loads and or load control devices and or controller devices which will reinitialize the low voltage communication network and automatically reconfigure the controller devices and load control devices connected to the network.
1. A system for controlling the application of electrical line power to a plurality of electrical loads comprising:
a line power network operatively connected to the plurality of electrical loads;
a low voltage power and communication network separate from the line power network;
one or more load control devices operatively connected to the low voltage power and communication network, each load control device transmitting one or more identification signals and one or more control signals through the low voltage power and communication network, for indirectly controlling the application of electrical power to one or more of the plurality of electrical loads;
at least one controller device operatively connected to the one or more load control devices through the low voltage power and communication network, said at least one controller device having a configuration means and providing electrical power to the low voltage power and communication network;
processing means in each of the at least one controller devices, said processing means for receiving and processing identification signals from each of the one or more load control devices and each of the one of more controller devices and the plurality of loads and using the configuration means to generate a plurality of configuration signals upon initial application of electrical power to the system, the processing means transmitting the plurality of configuration signals to the one or more load control devices and the one of more controller devices, the processing means further for receiving and processing one or more control signals from the one or more load control devices and directly controlling the application of electrical power to one or more of the plurality of electrical loads according to the one or more control signals and the plurality of configuration signals.
2. The system of claim 1 wherein the at least one first controller device provides line power to a first portion of the plurality of electrical loads.
3. The system of claim 1 wherein each of the load control devices includes a visual indicator for indicating the power status of the one or more loads of the plurality of electrical loads to which the load control device is bound.
4. The system of claim 1 wherein each of the load control devices includes two or more load control assemblies.
5. The system of claim 3 wherein each of the load control devices must receive a confirmation signal from a controller device that a load is on before the bound load control device can display an on status.
