KMD-7401C | Controller: HPU, Clock

The KMD-7401 and KMD-7401C are intelligent, programmable, 4 input/4 output direct digital controllers. Each controller is capable of independent, stand-alone operation or may be networked together using the same peer-to-peer communications format as other KMC Digital Controllers. The KMD-7401C has auto-reset of time after power restoration.

Application

The KMD-7401 and KMD-7401C controllers were specifically designed for Heat Pump Unit applications and contain factory programmed (canned) control sequences with descriptors. The factory programming has options for controlling a fan, compressor, reversing, valve, and optional auxiliary heating. 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-7401 and KMD-7401C. This allows the controllers to be completely user programmable.
