Description
The Heatcraft Refrigeration 89904904P Beacon II Sensor Kit is an integrated sensor set used with electronic refrigeration control in HVAC systems. It is applied in commercial refrigeration equipment such as walk-in coolers and freezers, where it provides temperature and system conditions to the control board. The sensors monitor coil and box conditions and transmit resistance-based signal that allow the controller to regulate refrigerant flow, defrost cycles, and compressor operation. It is typically installed at the evaporator and sensing points within the refrigeration assembly, ensuring accurate input data for coordinated control.
