Description
The Heatcraft Refrigeration 08A11175 Fan Delay is a control unit to regulate blower operation timing after heating or cooling cycles for HVAC systems. It is used in air handling units, furnaces and refrigeration equipment where fan start and stop sequencing is controlled. The component controls the continuation of airflow for a predetermined time following the shutoff of the compressor and/or burner, allowing the coils to continue to exchange thermal energy with the air. It is often used in commercial and residential assemblies. It controls fan operation in system control circuits ensuring consistent airflow conduct during fan operating transitions across systems.
