The Lochinvar & A.O. Smith 100208404 is a Pressure Switch, an essential safety component in HVAC systems, most often found in water heaters and boilers. It monitors the air pressure in the system to make sure that air gets moved into and out of it correctly, and prevents malfunctions, like a backdraft or improper combustion. The switch permits the burner to ignite when the input pressure is detected at the correct level to minimize wasted fuel. Key benefits of the proposed system are improved safety, system efficiency, and reliable performance. It’s this switch that is necessary to keep proper system airflow, prevent potential damage, and keep the equipment in top condition for as long as possible.
