Abstract

A self configuring air conditioning system. The system includes a system controller for an air conditioning system operably connected to a compressor and an expansion valve, a first portable wireless remote controller for providing commands and information to the system controller by wireless transmission, and a second portable wired remote controller for providing commands and information to the system controller by wired transmission. The system further includes a wireless receiver operably connected to the system controller for receiving wireless remote transmissions from the first portable wireless remote controller, and an interface operably connected to the system controller for receiving wired remote transmissions from the second wired remote controller. The system also includes means, operatively associated with the system controller and responsive to the interface, for automatically establishing a first air conditioning system operating configuration if the wired remote controller is present, and for establishing a second air conditioning system operating configuration if the wired remote controller is absent.

Claims

1. A method of configuring an air conditioner for remote control by either a wired receptacle or a wireless receiver comprising the steps of:

determining, independently of a control wire connection between the air conditioning system and a portable wired remote controller, if the portable wired remote controller is physically connected to the air conditioning system by means of the wired receptacle;

providing an indication that the portable wired remote controller is physically connected to the wired receptacle;

automatically configuring the air conditioning system to operate using the portable wired remote controller if the portable wire remote controller is physically connected to the air conditioning system;

automatically configuring the air conditioning system to operate with a wireless remote controller and the wireless receiver if the portable wired remote controller is not connected to the air conditioning system; and

operating the air conditioning system in accordance with the established configuration.

2. The method of claim 1 including the further steps of periodically re-executing the determining step, and excluding the operation of the nonconfigured operation until the result of the determining step changes.

3. The method of claim 1 including the further step of providing a thermostat function in the wireless remote controller.

4. The method of claim 3 including displaying thermostat function parameters on a liquid crystal display on the wireless remote controller.

5. The method of claim 1 including the further step of displaying system status and commands on a liquid crystal display on the wireless remote controller.

6. The method of claim 1 including the further step of automatically upgrading from a wired remote controller to a wireless remote controller.

7. The method of claim 1 including the further step of automatically downgrading from a wireless remote controller to a wired remote controller.

8. The method of claim 1 including the further step of transmitting commands and information from the wireless remote controller to the air conditioning system using infrared media, ultrasonic media, radio frequency media, or spread spectrum radio frequency media.

11. The system of claim 1 wherein the first portable wireless remote controller provides a thermostat function.

12. The system of claim 1 wherein the inside heat exchanger is within a housing which includes storage within the housing for either the first or second remote controller.

13. The system of claim 1 wherein the first portable wireless remote controller includes a liquid crystal display.

9. An air conditioning system comprising:

an outdoor heat exchanger;

an indoor heat exchanger;

refrigeration conduit for serially connecting the outdoor heat exchanger to the indoor heat exchanger, and the indoor heat exchanger to the outdoor heat exchanger;

means for controlling the operation of the outdoor heat exchanger, the control means including an infrared receiver and a wired remote receptacle operably connected to the control means by a control wire connection;

wherein the control means includes means, independent of the control wire connection, for determining the presence of a connector in the wired remote receptacle;

means, responsive to the determining means, for inhibiting the operation of the infrared receiver if a connector has been determined to be in the receptacle;

means, responsive to the determining means, for inhibiting the operation of the wired remote receptacle if a connector is not in the receptacle;

means, responsive to the determining means, for enabling the operation of the infrared receiver if a connector is not in the receptacle; and

means, responsive to the determining means, for enabling the operation of the wired remote receptacle if a connector has been determined to be in the receptacle;

wherein the determining means includes a contact switch in the wired remote receptacle.

10. A self configuring air conditioning system comprising:

an air conditioner including an outside heat exchange unit, an inside heat exchange unit, first refrigerant conduit connecting the outside heat exchange unit to the inside unit, second refrigerant conduit connecting the outside unit to the inside unit;

a system controller for the air conditioning unit operably connected to the outside heat exchange unit;

a first portable wireless remote controller for providing commands and information to the system controller by wireless transmission;

a second portable wired remote controller interconnected to the system controller by a control wire connection and providing commands and information to the system controller by wired transmissions on said control wire connection;

means, operably connected to the system controller, for receiving wireless remote transmissions from the first portable wireless remote controller;

means, operably connected to the system controller, for receiving wired remote transmissions from the second wired remote controller, the wired remote receiving means including means, independent of the control wire connection, for providing an indication that the second wired remote controller is physically connected to the system controller;

means, operatively associated with system controller and responsive to the wired remote receiving means, for automatically establishing a first air conditioning system operating configuration if the wired remote controller is physically connected to the system controller and for establishing a second air conditioning system operating configuration if the wired remote controller is absent; and

means responsive to the automatic establishing means, for disabling all non-established air conditioning operating system configurations.

14. An air conditioning system comprising:

an outdoor heat exchanger;

an indoor heat exchanger;

refrigeration conduit for serially connecting the outdoor heat exchanger to the indoor heat exchanger, and the indoor heat exchanger to the outdoor heat exchanger;

means for controlling the operation of the outdoor heat exchanger, the control means including an infrared receiver and a wired remote receptacle;

wherein the control means includes;

means for determining the presence of a connector in the wired remote receptacle;

means, responsive to the determining means, for inhibiting the operation of the infrared receiver if a connector has been determined to be in the receptacle;

means, responsive to the determining means, for inhibiting the operation of the wired remote receptacle if a connector is not in the receptacle;

means, responsive to the determining means, for enabling the operation of the infrared receiver if a connector is not in the receptacle; and

means, responsive to the determining means, for enabling the operation of the wired remote receptacle if a connector has been determined to be in the receptacle;

wherein the determining means detects the presence or absence of a jumper within a plug attached to the wired remote receptacle.
