Heatcraft Refrigeration 28910103 Control Board
The Heatcraft Refrigeration 28910103 Control Board is a critical replacement component for Beacon II refrigeration systems, engineered to handle precise evaporator management in commercial walk-in coolers and freezers. As a veteran-grade OEM replacement part, this Beacon II controller integrates advanced microcomputer logic to regulate electric expansion valves (EEV), compressor cycling, and specialty defrost schedules. By replacing the Heatcraft 28910101, the 28910103 version offers updated firmware compatibility, ensuring seamless polling of board versions when configured in master/slave evaporator arrays.
For field technicians, the 28910103 circuit board simplifies diagnostics through its onboard LED display, capable of throwing specific error codes for suction pressure transducers, room sensors, and communication loops. This Heatcraft Beacon II board also supports Smart Defrost algorithms, which reduce energy consumption by initiating defrost cycles only when frost accumulation is detected rather than on a fixed timer. Whether you are servicing a Bohn, Larkin, or Climate Control unit, this board maintains tight superheat control and provides a lockable interface to prevent unauthorized setpoint tampering in the field.
Key Benefits- Enhanced System Logic: Optimized for Beacon II refrigeration systems, providing superior temperature stability and EEV control compared to traditional mechanical thermostats.
- Flexible Configuration: Supports multiple refrigerant profiles including R-404A, R-448A, and R-449A, selectable via the onboard programming menu.
- Multi-Evaporator Sync: Designed for easy integration into master/slave configurations via a simple daisy-chain 18-gauge communication wire.
- Integrated Diagnostics: Real-time monitoring of box temperature and system faults reduces troubleshooting time on the job site.
How do I set the board as a Master or Slave?
Access the programming menu and locate the "SLA" setpoint. Use the enter and monitor buttons to toggle between master and slave modes before initializing the Smart Controller loop.
What is the standard power requirement for this control board?
The board operates on a 24 VAC power supply. Always verify the evaporator transformer is tapped correctly (208V vs 240V) to prevent low-voltage errors on the 28910103 controller.
Can this board replace the older 28910101 model?
Yes, the 28910103 is the direct OEM replacement for the 28910101. It will automatically poll existing boards in the system to determine firmware compatibility for shared parameters.
