Controller: AHU, KMDigital
The KMD-7301 and KMD-7301C controllers are intelligent, programmable, 4 input/4 output direct digital controllers. Each controller is capable of independent, stand-alone operation or may be networked with other controllers using the same peer-to-peer communications format as other KMC digital controllers. The KMD-7301C includes auto time reset after power restoration.
The KMD-7301 and KMD-7301C controllers were specifically designed for air handling unit applications and contain factory programmed (canned) control sequences with descriptors. The factory programming has options for fan control based on occupancy/night setback limit/proportional hot and chilled water valve control, economizer and freeze protection routines. Program area 5 is for additional user programming. This feature allows the controllers to be user modified to add special sequences. The factory programming may also be removed to allow full use of all five programming areas in both the KMD-7301 and KMD-7301C. This allows the controllers to be completely user programmable.
