Environment

LON Devices

Cause

  1. Using the device for the first time or after re-flashing the firmware.
  2. Power cycling the device.

Resolution

If nvi has any binding it receives the value from source nvo.
If nvi does not have the binding then manually set the value.
If nvi is a multistate SNVT it returns to default value.
