Product Info

The EAA 21G2773B1STB44 Control Board is an internal machine management and signal-processing microcontroller board engineered for massive climate control infrastructure, commercial HVAC units, and industrial water chillers. Acting as the logical core of the compressor or evaporator subsystem, this circuit board processes thermal inputs from multi-stage sensor arrays and coordinates output relays to control motor velocity, expansion valves, and fluid pressure loops.

Operating Logic Power: Low-voltage DC input

Onboard Indicators: Multi-segment diagnostic status LEDs

Input Interfaces: Temperature thermistor sensor ports, pressure transducer feedback headers

Output Actuation: Multichannel solid-state control relays for solenoid and valve regulation

Communication Interface: Proprietary serial fieldbus link for master-slave chiller configuration networks
