Appendix V
Control System Field Conversion
The unit can be converted to a different control system in the field. Locate the unit’s
current control system in the “From” column and the new control system in the “To”
column that is in the same row as the current control system. Follow the steps outlined in
the “New” column to complete the field conversion.
NOTE: Contact the factory for the BACview Admin password if required and to
have the wiring diagram updated when doing a control system field conversion.
Failure to do so will result in inaccurate documentation that can complicate possible
future troubleshooting efforts.
