Resideo 50027910-001 Pressure Switch 321702-401 this sensor is engineered toThe Resideo 50027910 001 Pressure Switch is a high precision differential pressure switch engineered for air movement verification in HVAC and humidification systems. Designed as a direct replacement component for Honeywell TrueSTEAM models, including the HM506, HM509, and HM512, this switch ensures critical airflow is confirmed before the steam humidifier engages. For pros in the field, this means protecting the heat exchanger and ductwork from
