Heat/Cool Controller - FK203A Refrigeration Controller
FK 203A is a controller specifically designed for refrigerating units. It has 3 contact control outputs for compressor, evaporator fan and defrost heater.
Internal parameters provide protection against compressor overloads due to several starts repeated in a short time. The defrost parameters are programmable as is the evaporator fan operation. Alarms can be set to indicate working conditions outside the limits set. It can be fitted with a serial interface to form part of a RICS multi-unit system allowing viewing and control of parameters from a pc as well as data logging to record temperatures for tuning and for quality records.
