We lost communication to the MP580 furnace that is connected via COM5, after losing communication to the furnace there was an error on the BCU that stated incomplete binding. We unassigned the MP580 and reassigned with no prevail. Then we unassigned the MP580 cleared the ram and reset the BCU where we can still cannot read the points off of the MP580. There is an option to rebuild the MP580 however we don't want to create more problems. Can anyone give us further assistance with this I see there is an option for Rover to be used however we do not have that software. If someone does have access to Rover or know what may need to be done please let me know!
