A52x Series Refrigeration Controller with Adaptive Defrost Installation Instructions
Application
The A52x Series Refrigeration Controller with Adaptive Defrost provides refrigerated space control and defrost
control for medium and low temperature refrigeration applications.
The A525 Controller has five integral line-voltage, dry-contact relays to control the compressor, defrost heater or
solenoid, evaporator fans, and user-provided alarm devices. The controller can control resistive heat, hot-gas
bypass, or passive defrost. The controller can also control two-speed evaporator fans. The A524 Controller has
four integral line-voltage relays and controls the same devices as the A525 Controller. The LO-SPD AUX relay is
not available on the A524 Controller, which controls a single speed evaporator fan only.
The adaptive defrost feature allows the controller to adjust the defrost schedule to the minimum number of defrost
intervals required to maintain peak efficiency, save energy, and maintain consistent space temperature. The A52x
Controller has an IP65 enclosure with holes in the enclosure base for wall-surface mounting. An optional DIN rail
mount kit (
Part No. BKT524-1K) is also available.
Refer to the A52x Series Refrigeration Controller with Adaptive Defrost Technical Bulletin (LIT-12012405) for more
details on setting up, operating, and troubleshooting the A52x Controller. You can access and download the A52x
Controller Technical Bulletin from QuickLIT.

Sensor Wiring
See Table 3 on page 7 for information about wire gauge and maximum sensor wire length. See Table 12 and
Table 13 on page 11 for the sensor technical specifications.
Observe the following guidelines when you wire sensors to the A52x Controller:
• Sensor leads are not color coded or polarity-specific; you can connect either of the two sensor leads to the Sn1
or Sn2 terminal and a C terminal.
• Select only the sensor that is designed to operate in the ambient operating range that your A52x Controller is
intended to monitor and control.
• Keep the sensor leads as short as possible in your application. The additional resistance in long sensor cables
can create an offset between the actual temperature and the displayed temperature. Solder or butt splice
connections are recommended.
Use 0.30 mm2 (22 AWG), stranded-wires and twisted-leads cable with a cable shield for extending sensor cable
runs.
