A sound level control system for a heating, ventilation, and air conditioning (HVAC) system is provided. The sound level control system comprises an outdoor unit with a compressor, an outdoor fan, and an outdoor controller and a communication device located at a predefined distance from the outdoor unit. The communication device measures sound levels in response to operating the outdoor unit. The outdoor controller is configured to receive a first noise level limit for a predefined time period, receive an instruction related to selective control of the outdoor unit, selectively control both of the compressor to rotate at a first compressor speed and the outdoor fan to rotate at a first fan speed based on the noise level limit for the predefined time period, and receive information related to whether a sound pressure level at a predefined location exceeds the first noise level limit for the predefined time period.

Limiting operation of a HVAC system for low-noise municipalities

A method of operating a diagnostic data collection device and a diagnostic data bus for an HVAC system are disclosed. In an embodiment, the diagnostic data collection device includes a diagnostic communication interface and a flexible interface module. The interface module measures electrical properties associated with an HVAC component. Electrical properties may include a sensor output and may include analog and digital signals. The diagnostic data collection device generates an exception message if the sensed property is out of specification. Evaluation rules are provided to detect various types of failures, including transient failures, steady state failures, and trending failures. The diagnostic data collection device self-calibrates by recording electrical properties during normal operation of the HVAC equipment. A plurality of diagnostic data collection devices may be coupled by a diagnostic data bug independent of the HVAC system's control bus, to ensure operational integrity of the diagnostic system.

Method of operating a diagnostic data bus in an HVAC system

Apparatuses, methods and systems for configuring electronically programmable heating, ventilation, and/or air conditioning ('HVAC') systems are disclosed. One embodiment is a system comprising a server system in operative communication with a database, a remote client and an electronically programmable HVAC controller. The system is structured to transmit a template HVAC configuration profile to the client, receive from the client a modification of the template profile transmitted to the remote client, validate the modification, in response to a programming request from the client, transmit a programming instruction including a modified HVAC configuration profile to the HVAC controller.

Apparatuses, methods and systems for configuring electronically programmable HVAC system

A control device includes a graphical user interface for an automated schedule. The automated schedule may include multiple schedule periods. Schedule parameters may be adjusted by selecting a portion of one of the schedule periods, for example, on a touchscreen display. The control device may be a thermostat to control temperature in a building.

System and method for configuring a schedule

A diagnostic data collection device and a diagnostic data bus are disclosed. In an embodiment, the diagnostic data collection device includes a diagnostic communication interface and a flexible interface module. The interface module is configurable to measure one or more electrical properties associated with an HVAC component, such as voltage, current, resistance. Electrical properties may include a sensor output and may include analog and digital signals. The diagnostic data collection device generates an exception message if the sensed property is out of specification. Evaluation rules are provided to detect various types of failures, including transient failures, steady state failures, and trending failures. The diagnostic data collection device self-calibrates by recording electrical properties during normal operation of the HVAC equipment. A plurality of diagnostic data collection devices may be coupled by a diagnostic data bug independent of the HVAC system's control bus, to ensure operational integrity of the diagnostic system.

Diagnostic data bus for acquiring and communicating diagnostic information from HVAC systems

Systems and methods of operating a heating, ventilation, and/or air conditioning (HVAC) system are disclosed that may include starting a timer substantially concurrently with the HVAC system, entering a cooling cycle, and preventing a multi-speed blower in the HVAC system from changing speeds until the timer expires.

Latent capacity adjustment

A forced airflow air conditioning system includes a humidifier which is operable to humidify air bypassed from a supply air plenum to a return air duct or vice versa, the humidifier airflow being controlled by a damper closure member which is operably connected to a bimetal spring actuator or to an electric motor, both responsive to temperature of air flowing through the system. One embodiment includes an electric motor connected to the damper closure member and in circuit with a humidistat for opening the damper when humidification is required.
