Cause

An invalid value is being overwritten continuously to a local point (to the Room Controller) by a dashboard widget or a third party device(e.g. via Bacnet).

Resolution

The invalid value must be corrected before proceeding with the binding process.

 

Example: A value of 0 is being written to the Occupancy command point which only take values of ([1 = Local Occupancy], [2 = Occupied] or [3 = Unoccupied]). The write and read traffic generated prevents other room controllers from joining the network.
