zone valve controls?

steve novak

I am installing six zones with either taco 571's or Honeywell v8403's. Its a gas fired hot water system. I wanted some opinons on the Taco ZVC406 vs the Weil-McLain WMZV-6. I was also thinking the Honeywell R8889 but that only gives me four zone without expanding it.

ZVC406-exp

Taco, ZVC406-EXP gives you the capacity for the 6 zones, with one zone for priority, typically used for domestic water. An extra set of N/o, N/C, dry contacts dedicated to the priority zone Six, gives you the capacity to power a circulator without the need of an additional relay, saving you time, and money.. The N/C can be used for the primary pump, to eliminate the redundancy of both pumps running. Additionally, we offer an interface connection for an outdoor reset control, Two boiler staging control, or an injection mixing control. These are a few of the attributes the ZVC board has to offer. For your convenience I have attached the Catalog data off the Taco web site, www.taco-hvac.com. Please advise, if you have any additional questions or concerns. Joe Mattiello
