I have an Automatic By Pass valve model SBV22 by SUNVIC.
I am trying to find a simple way to calibrate setting so that it opens when
two ports valves in s-plan systems are shut (no heating or hot water)
and minimum flow when any of the heating or hot water is on.
The method described is quite complicated such as to set 20% above the
normal pressure when working so this does not open premature.
I find difficult how you would determine these setting figures.
I saw an other Auto by pass in Srewfix and that comes already set at 2 bar and the setting can be varied.
Is 2 bar a nominal value ?
