Buderus panel rad question

Ron Jr._3

I installed one in my living room last year . It has the manual flow setter valve under a cap . I know to line up the marking with a number or with N for full flow . But what exactly does the cap do ? It has a + and - sign and arrows indicating to loosen the cap brings it in the + area . Any idea what that does ? It does seem to push in a stud that's spring loaded . The instructions that came with it and the one online don't even address the cap at all .



Thanks in advance !

That Cap....

pretty much actvates what you set is up to. Very crude adjustment. More or less its  its a shipping cap.  You would prob be better off getting a TRV for it.

Thanks Kev

I'm looking for full flow / highest temp . I'm guessing if the cap is loose the temp will be higher ?



 It's connected into a baseboard zone with monoflow tees . Might install another this weekend in the kitchen . Hopefully .........

Shipping cap

It is a shipping cap to protect the circuit setter. Replace it with the correct TRV.

Thanks Paul

I'll look into a TRV . Since the rad is in the coldest room on the zone , I really don't need more specific control . Just full flow / highest temp . So if I set to N and leave the cap loose so it doesn't push in the spring loaded pin , I get what I'm looking for ?

Re: Buderus valve cap

Ron, Buderus also has a white knob that looks more like a trv knob but just used to turn on and off. Thats what I would do if you want this going full all the time. Leaving the balance ring in N position is full flow as I remember also. Good luck.

Hi Ron:



Yes, leaving that cap loose allows the valve to be in the fully open position.
