Zoning with Munchkin / Vision?

Nick_11

Looking at primary secondary piping with 4 baseboard zones, all homerunned to primary loop off a Munchkin. I've heard that Vision II 1025 card is not available. I understand that Vision I wiring is for 1 central pump, 1 indirect DWH w/priority. Could (should) I do this with a Vision I Controller? How?

Originally looking at Grunfos UPS15-58 IFC pumps. Any other solutions (Taco pzc pumps; Taco zone controllers, Tekmar controllers, etc.)that would give still take advantage of outdoor reset, indirect temp control, modulation, etc.?

Thanks

Vision I will provide

you outdoor reset on your baseboard heating system. This is typically a good idea. Using Vision I you will still need to do Primary/Secondary Piping (the Munchkin requires high flows). You will need a boiler pump that will pipe into your baseboard loop through a set of closely spaced tees. Then on your baseboard loop you can put your Circulating pump that will circulate out to your four zones.

Your Boiler Pump and DWS pump should be as Follows:

Munchkin 50 or 80.....Grundfos UPS15-42F speed 2

Munchkin 140..........Grundfos UP26-64F

Munchkin 199..........Grundfos UP26-96F
