Hi, I want to control a couple of zone manifolds with pumps as well as an Indirect with it's own pump.
So we have DHW, And a two zone manifold, and a three zone manifold.
Do I need two 3 zone controls or do I need a three and a four?
I was going to do a master / slave and have DHW priority but I am worried that Zone 1 on the slave might initiate priority.
