Hello community,

I am trying to create a plant loop with a boiler and a mixed water heater (acting as a HW storage tank) on the supply side and a low temperature radiant variable flow heating coil on the demand side. I asked a question a little while ago about how to do this (here) and got some great help. A suggestion was to use a tempering valve on the supply side to determine where the hot water should come from when there is demand by the radiant floor. I have played around with the tempering valve but keep getting errors.

I am currently getting this error: * Severe * TemperingValve object needs to be on an ACTIVE branch

Here is a picture of my plant loop.

Node 9 is the outlet of the boiler Node 4 is the plant loop setpoint node (setpoint manager at the right of the picture) Node 13 is the outlet of the pump

I have tried putting the valve on each branch of the supply side, before and after the boiler or hot water tank. I have posted a comment about this in another question I asked, but I thought it would be better to ask a new question where I can provide more information about what I have tried.

Thank you
