Systems and methods for configuring and communicating with HVAC devices

A mobile device for configuring a building device of an HVAC system, comprising:

• a display;
• and
• a processor configured to:
• receive data associated with at least one of diagnosis and operation of the building device, the data received from the building device using near field communication (NFC);
• display the data on the display;
• responsive to a command entered on a user interface of the mobile device, update the display to display a log of communications made using NFC with the building device on a logging screen wherein the log of the communications includes time stamps corresponding with the communications, wherein the logging screen provides at least a portion of the operational data and the time stamps corresponding to the at least the portion of the operational data;
• receive a configuration parameter update, the configuration parameter update replacing or modifying at least one of the configuration parameters;
• and
• transmitting the configuration parameter update to the building device via NFC.

A device interface application for a mobile device and for use with a building device, the device interface application comprising instructions causing the mobile device to:

• receive a plurality of configuration parameters of the building device from the building device using near field communication (NFC);
• receive logging data associated with the building device from the building device using NFC, the logging data comprising operational data and time stamps corresponding to the operational data;
• display the plurality of configuration parameters on a display;
• responsive to a command entered on a user interface of the mobile device, updating the display to display at least a portion of the logging data in a logging screen on the display, wherein the logging screen provides at least a portion of the operational data and the time stamps corresponding to the at least the portion of the operational data;
• and
• provide a configuration parameter update to the building device via NFC in response to at least one of a write commend provided using the mobile device or a write and lock command using the mobile device.
