Installing it in a system with significantly higher or lower tonnage will result in "hunting" or improper refrigerant distribution

This automatic reset limit switch is designed to protect the heat exchanger and blower assembly from thermal runaway by interrupting the burner circuit when temperatures reach the 200°F high-limit trip point

this inducer ensures flue gases are efficiently exhausted through 5-inch to 8-inch pipe diameters

This model features a NEMA 2 / IP54 rating

Durable Construction: Designed to withstand the high vibration and thermal cycling common in commercial HVACR environments

Siemens Building Technology VMP42.10(2) Valve 321042-401 Installing it in a systemThe Siemens VMP42. 10(2) is a versatile 1 2 inch globe valve body engineered for precise control of water and glycol solutions in HVAC terminal units. With a flow coefficient of 0. 47 CV, this unit is specifically designed to integrate with Siemens SSC actuators, facilitating seamless automation for hydronic applications. A key field proven feature of this model is its flexibility: out of the box, it performs as a two way valve, but removing the cap
