The A5xx Series Wall Mount Refrigeration and Defrost Controllers provide refrigerated space and defrost control for low and medium temperature refrigeration applications.
The A5xx Controller includes five line-voltage, dry-contact relays to control the compressor, defrost heater or solenoid, evaporator fans, and user-provided alarm devices. The A5xx Controller can control two-speed evaporator fans and resistive heat, hot-gas bypass, or passive defrost.
The A5xx Controller’s adaptive defrost adjusts the defrost schedule to the minimum number of defrost intervals required to achieve peak efficiency, save energy, and maintain consistent space temperature.
Refer to the A5xx Series Wall Mount Electronic Refrigeration and Defrost Controller Product Bulletin (LIT-12012987) for important product application information. The A5xx Controller includes an IP65 enclosure with holes in the enclosure base for wall and surface mounting. You can order an optional DIN rail mounting kit (part no. BKT524-1K).
