I'm getting an error that

   ** Severe  ** TemperingValve object needs to reference a node that is the outlet of a pump on its loop
   **  Fatal  ** Errors found in input, TemperingValve object LGSTORE1 ZN SERVICE WATER LOOP TEMPERINGVALVE

but the TemperingValve IS referencing the outlet node of a pump on its loop.

Here is the TemperingValve object with Node 137 as the pump outlet node.

Here is the pump with outlet Node 137.

Here is the branch with that pump on it.

And here is the BranchList with the pump and tempering valve on it. The first branch is a Pipe:Adiabatic, the second and third branches is a splitter mixer setup with the TemperingValve object and a WaterHeater:Mixed object, and the fourth branch contains a Pump:ConstantSpeed, WaterHeater:Mixed, and Pipe:Adiabatic from the previous screenshot.

Lastly, here is the splitter and mixer.

It looks like everything is connected correctly to me. Can anyone shed any light on this? Here is a link to download the IDF file.

Turns out that putting the pump object before the TemperingValve rather than after in the plantloop resulted in no errors from energyplus. This is not explicitly stated in the IO Reference, but other objects have similar conditions on relative placement of dependent objects in loops.

I will report this as a documentation bug.

Here is the working idf file if anyone cares.
