Circulating Pump Switching Relays

JAF

Deciding on the best pump relay for up to 10 zones in a residential set-up is not the easiest thing to do. There doesn't seem to be many mfg out there. What is even harder is to find a control that will integrate an air handler, humidifier and air-air heat exchanger. Any ideas on what has worked for you? Thanks

Zone Controls

Taco makes full line of hydronic zone controls. Switching relays for zoning with circulators, zone valve controls for valve zoning and hydro-air fan controls for air handlers. With the addition of outdoor reset controls that plug directly into the zone panels make for a simple but complete temperature and zoning solution. Taco also offers a complete wiring guide for their zone controls. Contact your local heating wholesaler or our website (taco-hvac.com) for more information. Thanks

Taco

Use Taco expandable zone valve controllers, and all the Taco gadgets for the best system. The only thing is outdoor reset I still use Tekmar. I'm not saying Taco's are bad in that department, I just haven't used them for that situation. But from personal experience, all their other controls are great.

Taco wins! A wide selection of switching and zoneing relays with extra cards for reset, post purge, etc.

I've tried a lot of brands and I am most impressed with the "green boxes"

Also, some of the pump manufactures offer relay boxes that fit right onto their pump wiring enclosure. Think B&G has some new ones out.
