Abstract

There is described a system and method for configuring, commissioning and troubleshooting an HVAC unit. A unit type configuration is established based on a type of HVAC system and temperature data, humidity data, and/or indoor air quality data. A fan configuration is established based on whether a variable frequency drive fan is identified. Cooling and heating stage configurations are established based on a compressor parameter and a heating stage parameter. An available auxiliary termination is identified in response to establishing the configurations. A safety is assigned to the available auxiliary termination in response to identifying the available auxiliary termination. An IO table is provided to an HVAC controller, which includes physical input/output assignments for the terminations of the HVAC controller based on the configurations and the assigned safety. For another embodiment, the fan configuration is established based on one of a traditional stage blower fan or variable frequency drive fan.

Claims (26)

1. A method for configuring, commissioning and troubleshooting an HVAC unit, the method comprising:

establishing a unit type configuration based on a type of HVAC system and at least one of temperature data, humidity data, or indoor air quality data;

establishing a fan configuration based on whether a variable frequency drive fan is identified;

establishing cooling and heating stage configurations based on at least one compressor parameter and at least one heating stage parameter;

identifying at least one available auxiliary termination in response to establishing the unit type configuration, the fan configuration, and the cooling and heating stage configuration;

assigning at least one safety to the at least one available auxiliary termination in response to identifying the at least one available auxiliary termination;

providing an IO table, the IO table including physical input/output assignments for input/output terminations based on at least one configuration and the assigned at least one safety; and

receiving the IO table at the HVAC controller and configuring the input/output terminations of the HVAC controller based on the physical input/out assignments of IO table.

2. The method as described in claim 1 , further comprising identifying a plurality of unavailable terminations of the HVAC controller in response to establishing the unit type configuration, the fan configuration, and the cooling and heating stage configuration.

3. The method as described in claim 1 , further comprising establishing at least one supplemental configuration based on identification of at least one of a sensor, an economizer mode, a damper actuator, an exhaust fan, or a demand control ventilation,

wherein identifying the at least one available auxiliary termination includes identifying the at least one available auxiliary termination in response to establishing at least one supplemental configuration as well as establishing the unit type configuration, the fan configuration, and the cooling and heating stage configuration.

4. The method as described in claim 1 , wherein the at least one safety is selected from a group consisting of a clog filter switch, a smoke detector, an emergency shutoff, a drain pan clog switch, a freeze protection, a pressure switch, or an alarm output.

5. A system for configuring, commissioning and troubleshooting an HVAC unit comprising:

a mobile device configured to:

establish a unit type configuration based on a type of HVAC system and at least one of temperature data, humidity data, or indoor air quality data;

establish a fan configuration based on whether a variable frequency drive fan is identified;

establish cooling and heating stage configurations based on at least one compressor parameter and at least one heating stage parameter;

identify at least one available auxiliary termination based on the unit type configuration, the fan configuration, and the cooling and heating stage configuration;

assign at least one safety to the at least one available auxiliary termination based on the at least one available auxiliary termination; and

provide an IO table including physical input/output assignments for input/output terminations based on at least one configuration and the assigned at least one safety; and

an HVAC controller receiving the IO table and configuring the input/output terminations of the HVAC controller based on the physical input/out assignments of IO table.

6. The system as described in claim 5 , wherein the mobile device identifies a plurality of unavailable terminations of the HVAC controller based on the unit type configuration, the fan configuration, and the cooling and heating stage configuration.

7. The system as described in claim 5 , wherein:

the mobile device establishes at least one supplemental configuration based on identification of at least one of a sensor, an economizer mode, a damper actuator, an exhaust fan, or a demand control ventilation, and

the mobile device identifies the at least one available auxiliary termination based on at least one supplemental configuration as well as the unit type configuration, the fan configuration, and the cooling and heating stage configuration.

8. The system as described in claim 5 , wherein the at least one safety is selected from a group consisting of a clog filter switch, a smoke detector, an emergency shutoff, a drain pan clog switch, a freeze protection, a pressure switch, or an alarm output.
