An HVAC controller, a method for operating a HVAC unit and a HVAC unit are disclosed herein. In one embodiment, the HVAC controller includes: (1) a memory configured to store a unique default network address for the controller and (2) a processor configured to automatically generate the unique default network address based on a seed value that is uniquely associated with the HVAC unit.

HVAC unit, a method of generating a network address for a HVAC unit and a HVAC controller therefor

One aspect of the disclosure describes a controller for a heating, ventilation, and air conditioning (HVAC) unit. In one embodiment, the HVAC controller includes an interface and a processor. In this embodiment, the interface is configured to receive a delay originating signal. In one embodiment, the processor is configured to: (1) automatically generate an offset delay value for the HVAC unit upon receipt of the delay originating signal; (2) apply the offset delay value based on an offset enabled configurable parameter; and (3) delay starting identified components of the HVAC unit based on the offset delay value.

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.

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.

Airflow managing system, a method of monitoring the airflow in an HVAC system and a HVAC system

An HVAC controller and a method of controlling an HVAC system. In one embodiment, the controller includes: (1) a processor couplable to at least one indoor air quality sensor to receive values therefrom representing at least three levels of indoor air quality and (2) memory coupled to the processor and configured to store a software program capable of causing the processor to control an HVAC system based on magnitudes of the values.

Heating, ventilation and air conditioning system controller having a multifunctional indoor air quality sensor and method of controlling the system based on input from the sensor

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.

Customer equipment profile system for HVAC controls

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.

Air conditioning wiring system

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.

HVAC equipment phase and voltage monitor and control

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.
