Abstract

A room energy conservation system has a radio frequency transmitter located within a master controller. When an occupant leaves the room, the radio frequency transmitter communicates to a remote receiver to limit the electrical power available from a coupled electrical switch.

Claims

1. An energy conservation system comprising:

a master controller activated by a room occupant action;

a radio frequency transmitter located within said master controller and having a broadcast range;

a radio frequency receiver remote from said radio frequency transmitter and coupled to an electrical switching circuit responsive to a radio frequency signal received from said radio frequency transmitter; and

a controlled power device coupled to the electrical switching circuit such that the device is coupled to an energy source upon activation of said master controller.

2. The energy conservation system of claim 1 wherein said master controller in a deactivated state causes said electrical switching circuit to deactivate said controlled power device.

3. The system of claim 1 wherein the master controller is mounted within a lodging room proximal to an entryway.

4. The system of claim 1 wherein the room occupant action that activates said master controller is insertion of a card into said master controller.

5. The system of claim 1 wherein said radio frequency transmitter is a crystal.

6. The system of claim 1 further including a thermostat control unit.

7. The system of claim 1 wherein the radio frequency transmitter further comprises a frequency modulation switch that allows for the transmitted frequency to be varied.

8. The system of claim 1 wherein the electrical switching circuit is a relay.

9. The system of claim 1 wherein the electrical switching circuit is a power transistor.

15. Use of a radio frequency signaling system as claimed in claim 1 to lessen energy consumption in a vacant room.

10. A process of room energy conservation comprising the steps of:

activating a radio frequency transmitter upon a room occupant action within a room;

sending a radio frequency signal from said transmitter to a radio frequency receiver coupled to an electrical switching circuit within a controlled power device;

activating said controlled power device in response to the radio frequency signal being received by the receiver; and

deactivating the RF transmitter upon a room occupant action when leaving the room.

11. The process of claim 10 further comprising the step of:

modulating a thermostat control unit with a radio frequency signal.

12. The process of claim 10 wherein the master controller is mounted within a lodging room proximal to an entryway.

13. The process of claim 10 wherein the electrical switching circuit is a relay.

14. The process of claim 10 wherein the electrical switching circuit is a power transistor.
