About the BAC-7401
This section provides a general description of the KMC Controls
BAC-7401 controller. It also introduces safety information. Review
this material before installing or operating the controller.
The BAC-7401 is a native BACnet, fully programmable controller designed to
control heat pump units. Use this versatile controller in stand-alone environments or
networked to other BACnet devices. As part of a complete facilities management
system, the BAC-7401 controller provides precise monitoring and control of
connected points.
