Wirsbo manifold adjustment/temp differential

wrxz24 Member Posts: 298
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.

    temp differential

    ME was gracious enough to message me info on temp changes with the 7-10 degree differential with the system up and running.  I now have 90 degree water going out and 83 degree water coming in.
