Description
The AM102R-UT-1 is a thermostatic mixing valve from Resideo (Honeywell Home) for hydronic heating service, 1 inch, NPT 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.
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.
