34" WC but the switch remains open (check for continuity across terminals)

making it essential for high-demand industrial and commercial heating applications

As a direct successor to the DHY1220 and DHY1295

This left-hand specific coupler is designed to eliminate slippage and ensure responsive adjustment of the air damper within the ductwork

allowing technicians and facility managers to identify which specific detector has entered an alarm state when the detector itself is not easily visible

Aaon OE250 Sensor Els PW 17895 34" WC but the switchThe Aaon OE250 Outside Air Temperature Sensor is a critical component for achieving precise HVAC head pressure control and economizer logic in Aaon rooftop units.
