Abstract: A wall plate for mounting and supporting an electrical controller (e.g. a switch), an electronic controller (e.g. an electronic thermostat), or a similar wall-mounted electrical equipment, to an electrical outlet box is disclosed. The wall plate is configured to be secured to the outlet box via fasteners. The wall plate comprises a generally central opening through the electrical wires located in the outlet box can be accessed. The wall plate also comprises at least one outwardly extending lug configured to be received in a corresponding recess in the controller, and an outwardly extending supporting base configured to support and secure the controller to the wall plate. The wall plate allows the controller to be mounted to it instead of being mounted to the outlet box, thereby easing the installation of electrical and/or electronic controller.

Abstract: A control system is disclosed which comprises a first control module generally integrated into a controlling device (e.g. a thermostat), and a second control module generally integrated into an electrical apparatus (e.g. a heating apparatus) under the control of the controlling device. The second control module is responsive to command signals remotely transmitted thereto by the first control module over the power lines which power the electrical apparatus. In response to the signals, the second control module can selectively turn on, or off, or modulate, some or all of the electrical components (e.g. heating elements, fans) of the electrical apparatus.
