Field-Serviceable: Rigid yet flexible aluminum allows you to bend and cut to exact fitment requirements on-site

calibrated to "open" and break the electrical circuit at 160 degrees F and "close" to restore operation once the temperature drops to 120 degrees F

What causes a 160-degree rollout switch to trip

it eliminates the mechanical failure points found in traditional electromagnetic relays

The HH12ZB200 is the sanctioned direct replacement for HH12ZA199

McDonnell & Miller P-1-SS Probe Rod Field-Serviceable: Rigid yet flexible aluminumThe McDonnell & Miller P 1 SS Probe Rod (Part Number 179530) is a critical component for high precision liquid level control in hdyronic and steam systems. Engineered from 12 inch 316 stainless steel, this probe rod provides superior corrosion resistance and structural integrity for long term immersion in boiler environments. Designed for seamless integration with RS series sensors, the P 1 SS is commonly utilized with PCH, PCL, and LPC 2000 liquid
