Installing this on a 230V circuit will cause immediate failure of the heating element

providing a hard break in the safety circuit when internal plenum temperatures exceed the factory-defined threshold

Whether you are performing a routine control board swap or a complex repair on an 80MGF or G24M unit

it manages the internal water pressure and temperature fluctuations typical in high-volume environments

Durable Construction: High-grade copper sheath provides superior heat conductivity and corrosion resistance

Honeywell 30112A Potentiometer Els PW 17895 Installing this on a 230VThe Honeywell 30112A Potentiometer is a critical component for technicians managing Modutrol motor series and relay control systems. This 135 Ohm potentiometer is engineered for seamless integration with the S443A manual potentiometer, providing precise resistance modulation for HVAC industrial automation and commercial boiler applications. Built to withstand demanding boiler room environments, it operates effectively across a temperature range of 18C
