The N323R is a Refrigeration controller designed to control the temperature of refrigeration cases and cold rooms, embedding several specialized functions for best system performance. The N323R can read two temperature probes (controller and defrost probes) and has three relay outputs for controlling the compressor, the defrost and the fan. The controller can be ordered with optional features such as to comply with the application’s requirements. The label on the instrument housing shows the complete instrument configuration.
