Description
The York S1-S90-294Q Fan Relay controls motor operation by switching electrical circuits via a 120V coil with a 50/60 Hz frequency. It is extensively used in commercial and residential HVAC systems to ensure consistent fan sequencing and airflow management in furnaces, air handlers, and packaged heating and cooling units. The responsiveness to control signals that cause blower motors to start or stop during heating or cooling cycles. Its structure ensures robust electrical switching performance, allowing for coordinated equipment operation and consistent air circulation between connected components.
