APPENDIX 1: LC-SERIES CONTROLLER ARCHITECTURE

CAUTION: The Bard DC-FCU System has been pre-programmed with what is widely considered to be the best
settings for efficiency and operation. Any changes to internal programming through the LC-Series Controller or the
TEC-EYE not covered within this manual may cause the systems to operate improperly, cause internal damage to
the HVAC units, cause the shelter to overheat, or other very serious consequences. Although complete controller
programming architecture for both the LC-Controller and TEC-EYE has been provided, going outside the boundaries
of what has been covered in this manual not recommended.
