Applications
Primarily used as a fan-proof-of-operation (fan status) switch and dirty filter alarm in AHUs, fan coil units, and exhaust fan systems. When pressure drops below 300 Pa (fan stopped or filter blocked), the relay switches to trigger a BAS alarm. A fundamental safety and diagnostic device in commercial HVAC systems required by ASHRAE and local MEP codes.
