The Armstrong 110123-121 is an aquastat designed for Astro circulators, featuring a bi-metallic disc snap-acting control. This unit is suitable for maintaining a hot water range between eighty-five degrees Fahrenheit and one hundred five degrees Fahrenheit.
This aquastat effectively regulates the temperature in hot water lines and is designed for use in potable hot water re-circulation systems. It automatically activates the circulator when temperatures fall below eighty-five degrees Fahrenheit and deactivates it when temperatures exceed one hundred five degrees Fahrenheit.
