TEMPERATURE LIMIT & LWCO 3150 HYDROSTAT

The Hydrostat is a universal temperature limit control combined with a low water cutoff, when used with the “hydrostat wells”. When used as a replacement aquastat only, an existing well can be used. This control replaces cold start and triple action aquastats using the existing wells. Replace the existing well with a “hydrostat well” and enjoy the benefit of a built in low water cutoff. Digital read out with LED diagnostics. Uses same terminal designations as standard aquastats. The 3150 is for use with oil boilers and the 3100 for use with gas boilers.
