Compressor Controller 20100005

Controller used for managing the temperature of refrigerators and freezers.
Nirrau Compressor Controller 20100005 is a professional temperature control system designed for refrigerators and freezers using R290 refrigerant. It integrates a master temperature control module and a slave display module to deliver stable, reliable operation for long-term refrigeration applications.

The controller is divided into two core components:

  • Temperature Control Module (Master): Receives analog and digital inputs (defrost NTC sensor, ambient NTC sensor, door contact sensor) and manages 4 independent relay outputs for compressor, defrost heater, internal micro fan, and lighting. It maintains operation with the last programmed settings even if communication with the display module fails.
  • Display Module (Slave): Provides a user interface to show real-time temperature, configuration status, and system alarms. It communicates with the control module to relay user settings and operates as a passive viewing component— the system can function fully without it.

All electrical and sensor connections must be made to the control module’s relay box, not the display module.
