    I think I remember hearing when ordering, some of the deverters have a shut off valve. Check the sides of the valves.Also. ..... you only use deverters when you daisy loop the radiators. I would take it off with a manifold.

    The throttle valve may be stuck , plugged or NG ? v
    I have enough experience to know , that I dont know it all

    Possible Solution

    Any chance supply and return are reversed? This has happened to me with these rads. Sympton is very little heat. Swap feeds and all is good. Also diverter valves might not be adjusted correctly for % of flow that gets diverted vs gets into radiator. There is a red knob on the valve where you put the thermostatic valve. It can also be adjusted for flow. Finally, check thermostatic valve. These are great rads when working properly!
