While the HR92's all have their own independent logic, when they're in a single room zone they are all receiving the same inputs - the same set point and the same measured room temperature relayed via the controller, so they tend to make the same decisions about the valve pin position.

It will be interesting to see what the three different valve pin positions are when checked.
I'll let you have the readings, I have anyway switched to full stroke the hr92...

Let's see...
