Wirsbo manifold adjustment
Just curious about the little back disc that controls the flow on the older cooper wirsbo manifolds 7 outlet with the black caps. I saw a post on the Main Wall about someone who said to adjust all of the black disc so that it is about a dimes thickness above the brass collar. Mine discs were level or slightly below and there was about a 14 degree temperature differential (90 vs 76 )between each of supply and return loops. Temperature was 4 degrees.
My question is this. Is there a recommended temp difference between the supply and return loops after the system has been up and running?
Thanks in advance.
