If your BOFA unit is running and loses power, the standard behavior when power is returned to the unit is for it to return to an idle state - even if the unit was running when power was lost.
Some customers would like the behavior to be for the unit to return to the last state it was in when power was lost.
If you wish for this to be your system's behavior, install the attached CON File Foreced Run Option.con onto your BOFA unit. This will cause the system to return to its previous state after about 15 seconds when power has been returned to the unit.
You will save this file to a USB stick and upload it to the BOFA unit via the BOFA unit's USB port.
