Description
The Resideo AM100R-US-1 is a 1/2″ union-end thermostatic mixing valve engineered for reliable, precise water temperature control in hydronic heating and domestic hot water systems. With a broad operating range of 70°F to 180°F, this valve automatically blends hot and cold supply water to deliver a consistent, user-set outlet temperature — protecting occupants from scalding and preventing system inefficiencies caused by temperature fluctuations.
The union connections on both inlet and outlet ports simplify installation and future serviceability, allowing the valve body to be removed without disturbing the surrounding piping. This makes the AM100R-US-1 an ideal choice for new construction and retrofit hydronic applications alike.
