4-20mA (via 500 Ohm resistor)

the 55440 is specifically sized for the 3/4" NPT Spirax-Sarco TD52 and related thermodynamic models

By maintaining the factory-specific logic for fan delays and safety lockouts

it provides the throttling accuracy typically reserved for more expensive globe valves while maintaining the high close-off capabilities of a ball valve

Honeywell E3SRMNO2 Remote Sensor R-410A they must be sourced separatelyThe Honeywell E3SRMNO2 is a professional grade remote nitrogen dioxide (NO2) sensor designed for seamless integration with the E3Point standalone gas detection system. Engineered for high risk environments such as parking garages, loading docks, and maintenance facilities, this remote mounted sensor provides critical monitoring of combustion byproducts. This unit is technically identical to part numbers 1309A0057 and ESRMNO2, ensuring full
