20100293991 | AIR CONDITIONING WIRING SYSTEM - A wiring system for use in an air conditioning system comprising a printed circuit board having a perimeter and wiring receptacles located proximate the perimeter 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. | 11-25-2010 |
20100295493 | HVAC EQUIPMENT PHASE AND VOLTAGE MONITOR AND CONTROL - 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. | 11-25-2010 |

The microcontroller is configurable to directly transfer the data between the memory and a portable flash memory device. The HVAC system control unit further includes a portable flash memory device interface for coupling the portable flash memory device directly thereto. | 11-25-2010 |
20100298985 | CUSTOMER EQUIPMENT PROFILE SYSTEM FOR HVAC CONTROLS - Disclosed herein is a heating, ventilating, and air conditioning (HVAC) unit and controller with memory provisions for storing, receiving, and transmitting customer equipment profiles. The controller may include a plurality of profiles that allows a selection thereof for restoration. A method for configuring HVAC equipment, including a customer profile database and efficiently transmitting unique customer and factory profiles, is also disclosed. | 11-25-2010 |
20100298988 | STAGGERED START-UP HVAC SYSTEM, A METHOD FOR STARTING AN HVAC UNIT AND AN HVAC CONTROLLER CONFIGURED FOR THE SAME - An HVAC controller, a method of starting a HVAC unit and a HVAC system are disclosed herein. In one embodiment, the HVAC controller includes: (1) an interface configured to receive a delay originating signal and (2) a processor configured to automatically generate an offset delay value for the HVAC unit upon receipt of the delay originating signal and delay starting identified components of the HVAC unit based on the offset delay value. | 11-25-2010 |
20100298993 | AIRFLOW MANAGING SYSTEM, A METHOD OF MONITORING THE AIRFLOW IN AN HVAC SYSTEM AND A HVAC SYSTEM - An airflow managing system for monitoring airflow of a HVAC system, a HVAC system and a method of monitoring the airflow in a HVAC system is provided. In one embodiment, the airflow managing system includes: (1) an air pressure sensor configured to obtain an air pressure measurement directly from a scroll of an air blower of the HVAC system and (2) a HVAC controller configured to determine an airflow rate for the HVAC system based on the air pressure measurement and corresponding parameters associated with the air blower. | 11-25-2010 |
20120122323 | AIR CONDITIONING WIRING SYSTEM - 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. | 05-17-2012 |
