slag buildup on the tips

the S1-024-25006-704 serves as a direct replacement to resolve furnace pressure switch stuck open codes and intermittent short cycling

What happens if the power goes out

Siemens Building Technology QPM2162 Sensor 321042-401 Optimized System Airflow: The ifDFor high performance demand controlled ventilation, the Siemens QPM2162 is the professional standard for multi variable duct sensing. This NDIR CO2 sensor provides critical feedback for CO2 concentration, relative humidity, and temperature, allowing for precise ASHRAE compliant air monitoring. This duct mounted sensor utilizes non dispersive infrared technology to ensure long term stability without the need for periodic field recalibrations, making it
