Review on 💧 Hydrolevel 3250 Plus Hydrostat Aquastat: Superior Water Level Control Technology by David Romo

This Aquastat would be a good replacement for Honeywell but the claimed features aren't very useful. The zoning function is supposed to save energy but seems to use too high a difference so my tankless coil boiler doesn't work either. I should leave the setting at 1. I like the digital display, ease of setup, and value.
