#1091 Missing proto for chilled water mixing

Karol Jarolimek Wed 6 Dec 2023

There is no proto for:

chilled water mixing valve cmd point

but there is:

hot water mixing valve cmd point

Is this an omission or on purpose?

I pushed a change to add it

Why are you mixing chilled water? A hot water mixing valve is for tempering hot water to a safe (non-scalding) level.

Are you mixing heating and cooling water? Maybe I am confused about the use case for these scenarios.

Thank you Brian.

@Doug I think some systems (e.g. chilled ceilings and beams) work at higher temperatures than cooling coils, so the chilled water is mixed with return.
