Description
The Bard HVAC 8402-146BX is an OEM replacement auto-reset, exposed-face limit control designed for use in Bard wall-mount and packaged HVAC equipment. Color-coded pink for easy field identification, this bimetal disc thermostat provides reliable high-limit protection by opening the circuit when temperatures reach the L185 set point (185°F) and automatically resetting once safe operating temperatures are restored.

Application
This limit control is engineered as a direct OEM replacement for Bard HVAC wall-mount packaged units. It mounts directly to the heat exchanger or plenum surface, sensing temperature through its exposed face. When the system exceeds the 185°F threshold — due to restricted airflow, dirty filters, or component malfunction — the disc opens the control circuit to shut down the heating element and prevent damage. Once temperatures normalize, the auto-reset function returns the unit to normal operation without requiring manual intervention.
