• Supports AKV electronic expansion valve applications
• Integrated refrigeration temperature and superheat control functions
• Modbus communication capability
• Suitable for maintenance and replacement of installed ADAP-KOOL systems

Technical Specifications

Compatible System and Applications

The controller is used in commercial refrigeration cabinets, supermarket display cases and evaporator control systems. Compatibility depends on the installed valve, sensors, wiring, communication network and controller parameter configuration.

Maintenance and Replacement Notes

AK-CC 550 is a legacy controller. Do not select a replacement only by the AK-CC 550 family name. Confirm order number 084B8020, supply voltage, software version, sensor configuration, valve type, wiring terminals and communication requirements. Migration to an AK-CC55 controller may require wiring and parameter changes.
