Aquastat
An Aquastat is a temperature control device used in heating systems, similar to how a thermostat works in your home. It monitors and controls water temperature in boilers and heating systems instead of air temperature. Think of it as a safety guard and temperature manager for hot water heating systems. When you see this term in a resume, it usually means the person has experience working with boiler systems and temperature controls. It's a crucial component that heating technicians, HVAC specialists, and boiler maintenance professionals work with regularly.
