Resideo AM102R-UP-1/U 1 in Union ProPress LF Mixing Valve R - Heat Only

The AM102R-UP-1 is a thermostatic mixing valve from Resideo (Honeywell Home) for hydronic heating service, 1 inch, ProPress connection.

A mixing valve solves a problem that has no other answer: a water heater has to be kept hot enough to suppress bacterial growth in the tank, and that temperature is too hot to deliver to a tap. The valve blends stored hot water with cold on its way out, so the tank stays hot and the fixture does not.

This is a heat-only valve. The R series is built for hydronic heating loops — radiant floor supply temperature, boiler protection, blending on a heating circuit. It is not for potable water service. Fitting a heat-only valve on domestic hot water puts a component outside its rating on the water people drink and bathe in. Check the model before ordering if the application is potable.

Union ProPress ends are pressed rather than soldered, and the unions mean the valve body still comes out without touching the pipe.

Set the outlet temperature with a thermometer at the fixture, not by the dial alone, and re-check it after the system has settled. Inlet conditions move the mix, and a valve set on a cold line reads differently once the loop is up to temperature.
