Patent number: 10012403Abstract: A wiring connector housing including a housing body having first and second ends and at least one interference tab extending outwardly from the second end is provided. The wiring connector housing further comprises spaced apart channels located through the housing body extending from the first end to the second end with the first end of the channels each configured to receive a quick connector therein. Each of the second ends of the spaced apart channels being located to register with and receive corresponding quick connect terminals therein. The at least one interference tab is configured to contact an isolation ridge of an electrical relay and thereby prevent the second ends of the spaced apart channels from being improperly registered with the corresponding quick connect terminals.Type: GrantFiled: January 27, 2010Date of Patent: July 3, 2018Assignee: Lennox Industries Inc.Inventors: Carlos O. Chamorro, Randall L. Lisbona, Rick A. Mauk

Patent number: 9909770Abstract: An HVAC controller, a method of operating an HVAC controller and an HVAC system employing the controller or the method. In one embodiment, the HVAC controller includes: (1) a processor couplable to at least two refrigerant pressure sensors via separate data paths to receive input signals therefrom and further couplable to a compressor stage and a condenser fan to provide output signals thereto, and (2) memory coupled to the processor and storing a software program having program instructions capable of causing the processor to command the compressor stage or the condenser fan to turn on irrespective of a state of an input signal generated by either of the at least two refrigerant pressure sensors, and generate an error message at least partially depending upon whether or not a high pressure shutdown occurs after the processor commands the compressor stage or the fan to turn on.Type: GrantFiled: December 19, 2014Date of Patent: March 6, 2018Assignee: Lennox Industries Inc.Inventors: Carlos O. Chamorro, Roger C. Hundt, John P. Stachler, Stephen A. Walter

Patent number: 8444442Abstract: A wiring system for use in an air conditioning system comprising a printed circuit board having wiring receptacles and wiring connectors. In one aspect, at least some of the wiring receptacles comprise two or more wiring sub-receptacles, and each of the wiring sub-receptacles includes a slotted sub-receptacle connection pattern. Furthermore, the slotted sub-receptacle connection pattern of each of the wiring sub-receptacles is different from every other sub-receptacle connection pattern. Each of the wiring connectors includes a ridged connection pattern that is different from every other ridged connection pattern of the wiring connectors, such that a given wiring connector is receivable within only one of the wiring sub-receptacles. An air conditioning system and a method of manufacturing is also provided.Type: GrantFiled: January 24, 2012Date of Patent: May 21, 2013Assignee: Lennox Industries Inc.Inventors: Steven C. Brown, Carlos O. Chamorro, Merlin K. Chapin, Robert W. Gilkison, Aylan A. Him, Randall L. Lisbona, Richard A. Mauk, Michael Renker

Patent number: 8368337Abstract: An HVAC unit includes a transformer and a system controller. The transformer is configured to receive power from a first and a second phase of a three-phase power source and to produce a first reduced-voltage waveform therefrom. The system controller is adapted to sample the reduced voltage waveform to determine a figure of merit of the three-phase power source. The controller is further configured to operate the HVAC unit in response to the figure of merit.Type: GrantFiled: January 27, 2010Date of Patent: February 5, 2013Assignee: Lennox Industries Inc.Inventors: Absalon Bonilla, Carlos O. Chamorro, Richard A. Mauk, John P. Stachler
