Patent ID: 8160749

Claim:
An energy conservation system comprising: a master controller providing control of power consumption to an occupant of a room through occupant action to create an occupied mode and otherwise be in an unoccupied mode; a thermostat controlled by said master controller; a master radio frequency transceiver located within said master controller and having a broadcast range; a second radio frequency transceiver remote from the master radio frequency transceiver and coupled to an electrical switching circuit responsive to a radio frequency signal received from said master radio frequency transceiver; a controlled power device coupled to the electrical switching circuit such that an energy input to said device is controlled by said master controller in the unoccupied mode wherein the room occupant action that activates said master controller is insertion of a card into said master controller or the activation of a slide switch; wherein said thermostat is in two-way radio frequency communication with said master controller; and wherein said second radio frequency transceiver following a successful receipt of the radio frequency signal with a command from the master controller provides a verification of the received command that is rebroadcast via a separate radio frequency to the master controller.
