Also, remember that mixing valves fail. I have had situations where mixing valves that served all of the units on a floor have failed on the hot side, resulting in a complete system having water above 120F. We have asked our Facilities group to ensure the valves are part of the building preventative maintenance plan after we had to rebuild or replace a number of them.
