CRC-1200 Digital Cold Room Controller with Defrost & Fan Control – Subzero

Product details Product Description The CRC-1200 Digital Cold Room Controller is a high-performance solution designed for complete cold room management, including compressor, defrost, evaporator fan, condenser fan, and auxiliary controls. It is suitable for commercial and industrial refrigeration systems where precise control and system protection are essential. This controller supports both time-based and temperature-based defrost with options for heater or hot gas defrost, ensuring efficient frost management in cold room environments. It uses dual NTC sensors for room and coil temperature monitoring, enabling accurate control of cooling and defrost cycles. The CRC-1200 is equipped with multiple relay outputs to control various components such as compressor, fans, heater, solenoid valve (pump down), and alarm systems, allowing complete refrigeration system automation. It also includes advanced features like quick freeze mode, post-drip logic, and evaporator fan control based on coil temperature. With RS485 Modbus communication support, the controller can be integrated into BMS or SCADA systems for remote monitoring. Built-in safety features such as fault logging, door input, high/low pressure protection, and compressor delay ensure reliable and secure operation in demanding HVAC/R applications.
