Abstract
Abstract An apparatus for controlling operation of diagnostic test modes with a remote control for a room air conditioner. Program keys are selected and activated to allow a user to input a particular diagnostic test mode to the air conditioner. The user then monitors the actions of the room air conditioner to ensure that the room air conditioner successfully completes the selected diagnostic test. Two remote control units are utilized, one to operate the room air conditioner in a conventional way while a second remote unit transmits codes to cause the air conditioner to run a diagnostic test. The remote control units includes a microprocessor to accept and process the entered selections for the diagnostic tests.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
An electronic control for use in operating a room air conditioner in a particular diagnostic test mode, said electronic control comprising: a remote control unit adapted to be located remote from said room air conditioner, said remote control unit including: input means for selecting the operational parameters of the particular diagnostic test mode of said room air conditioner and for generating selection signals; processing means for processing said selection signals into a plurality of output signals, said output signals including an encoded sequence corresponding to the particular diagnostic test selected said room air conditioner operating according to said encoded sequence; memory means for maintaining in memory said selection signals are operably associated with said processor means; and first wireless communication means for sending said output signals; and a room air conditioner control unit including a second wireless communication means for receiving said output signals, and switch means for controlling said room air conditioner in the particular diagnostic test mode selected, said switch means operatively connected to said second wireless communication means.
Claim 2
Dependent Claim
171 words
An electronic control for use in operating a room air conditioner in a particular diagnostic test mode, said electronic control comprising: a remote control unit adapted to be located remote from said room air conditioner, said remote control unit including: input means for selecting the operational parameters of the particular diagnostic test mode of said room air conditioner and for generating selection signals; processing means for processing said selection signals into a plurality of output signals, said output signals including an encoded sequence corresponding to the particular diagnostic test selected said room air conditioner operating according to said encoded sequence; memory means for maintaining in memory said selection signals are operably associated with said processor means; and first wireless communication means for sending said output signals; and a room air conditioner control unit including a second wireless communication means for receiving said output signals, and switch means for controlling said room air conditioner in the particular diagnostic test mode selected, said switch means operatively connected to said second wireless communication means.
Claim 3
Dependent Claim
27 words
The electronic control of claim 1 wherein said first and said second wireless communication means respectively send and receive said output signal via an intermittent infrared beam.
Claim 4
Dependent Claim
42 words
The electronic control of claim 1 wherein said input means includes a plurality of keys, said keys enabling said processor means to load said selection signals into said memory means, said keys further enabling and disabling the particular diagnostic test mode selected.
Claim 5
Dependent Claim
49 words
The electronic control of claim 1 wherein said input means includes a plurality of keys, said keys enabling said processor means to load said selection signals into said memory means, said keys further enabling and disabling a plurality of diagnostic test modes in said room air conditioner control unit.
Claim 6
Dependent Claim
25 words
The electronic control of claim 1 wherein said processing means prevents two different diagnostic test mode selection sequences from being loaded into said memory means.
Claim 7
Dependent Claim
36 words
The electronic control of claim 1 wherein said processing processes selection signals to create an output signal to force a power on reset of said room air conditioner control unit and leave a diagnostic test mode.
Claim 8
Dependent Claim
