or the unit cycling frequently due to high limit trips

often indicating the switch is stuck open or tripped due to airflow issues

Reliable Operation: Employs pilot operation to ensure consistent performance even in high-flow scenarios

protecting the heat exchanger from the stresses of restricted airflow or blower failure

This ensures the integrity of the ceramic insulators and the critical limit switch calibration remain at factory standards
