Engineered with a two-circuit hook-up (SPST)

Durable Construction: Features a nickel-plated bulb (1/4" x 5-9/16") to resist corrosion in harsh kitchen environments

It is essential for technicians performing routine maintenance or rebuilding the pressure pilot to ensure stable set-point control and prevent hunting or sluggish valve response

this zone adder utilizes plug-and-play connectivity to bridge additional dampers and thermostats into the existing master control logic

Precision Control: The limited knob design prevents over-adjustment while allowing specific differential tuning for optimized compressor cycles

Hydrolevel 500 Low Water Cut-Off Freon Engineered with a two-circuit hook-upThe Hydrolevel 500 Low Water Cut Off is a professional grade safety control engineered for hot water boilers in both residential and commercial applications. Operating on 24VAC, this electronic LWCO utilizes a probe to monitor water conductivity, effectively preventing dry firing and mechanical failure. Unlike mechanical float switches, this solid state control features no moving parts, eliminating the need for periodic blowdowns. The unit is equipped
