The Series PS-800 conductance-style, low-water cutoff boiler controls have been enhanced, says the company. These microprocessor-based controls are designed to provide contractors and install-ers with easy-to-understand troubleshooting diagnostics, continuous boiler protection against low-water conditions, and are suitable for steam and hot water boilers in residential, commercial, and industrial applications, the company says. Probe sensitivity has been doubled and a new shortened probe sensing feature indicates grounding problems, according to the manufacturer.
