Proviso Troubleshooting Guide – Delta Controls

The following describes various errors and troubleshooting steps.

This article is a work in progress.

General

Error message	What this means	Possible solution
Device type unsupported	The device is not supported. For example, you've scanned a Red5VAV controller using Proviso version 2.11 or earlier.	Use a supported device type with the applicable firmware version. Check that your firmware version is compatible with your device type. Update your firmware version as needed.
Device type mismatch	This error may occur if you are using the mass programming feature. For example, if you are programming multiple devices of the same type/model one after another but the device types do not match. This error may also occur if you're attempting to recover the data.	Re-try applying settings to the same device model. For example, if you're using Red5-EDGE, you must also apply your settings to the Red5-EDGE.
Data corrupted	This error indicates the NFC memory is corrupted.	Reboot the device.
Failed to transfer data to device	Writing to the device was not successful.	Keep phone close to device until the operation is complete.

See below for best practices when using NFC:

Double check the location of the NFC tag on the Delta Controls device and your smartphone reader. If you don't know where the NFC is located on your phone, you can look it up online.

Location of NFC tags on Delta Controls devices

Make sure you place your phone directly above the NFC tag and do not move your phone until the successful message displays. Some users have better success when they rest their phones directly on the surface of the device.
If you have a phone case, you may have more issues successfully connecting. Remove your phone case and try again.
Make sure the values are written to the device as intended when using NFC to write values. It is recommended to wait approximately 10 seconds before peforming a second read with Proviso.
