2+1 Hydrolink, using end ports for 3rd zone?

matt_65

Using a 2+1 Hydrolink with Alpha2 pumps for zoning, boiler on its own pump through the primary end ports to the left. I've got it flipped over and flanged for the first 2 zone pumps for baseboard and air handler, check valves installed in pumps.

I'm going to be running the 3rd zone as low temp from the "+1" end taps on the right to a mixer then pump then manifold, I can treat those end taps as a 3rd circuit in this case right?

(those straps are redundant, its secured tight with lags through the mounting holes)

Yes, but refer to the instructions about maximum flow rates.

yes you can use the end ports. I have also mounted them vertically.
I would add a good air separator also, the small air vent included need some help.
