Danfoss AK-CC 250A Refrigeration Controller (084B8528)

The AK-CC 250A is a universal temperature controller designed to manage TXV-based refrigeration systems – including cold rooms, freezer cabinets, and display cases used in supermarkets and retail environments. It replaces traditional thermostats and timer relays, combining multiple control functions in a single compact unit.

Key Features

• Dual compressor control – supports up to 2 compressors.
• Two reference temperatures – flexible setpoint configuration.
• Built-in MODBUS communication – ready for integration with supervisory systems, no additional modules required.
• Digital inputs – configurable for a variety of control functions.
• Clock with supercapacitor backup – retains time settings during power outages.
• Pt 1000 and PTC 1000 sensor support – with factory calibration exceeding EN 441-13 accuracy requirements.
• Front-panel buttons and seal – easy service access with protection against unauthorised setting changes.
• Quick installation – simplified mounting and wiring.

HACCP Compliance

The controller supports HACCP requirements through continuous temperature monitoring and logging of periods where alarm thresholds have been exceeded. Factory sensor calibration ensures measurement accuracy beyond the EN 441-13 standard.
