4.8 Rating 115 Reviews
I have installed many radiant systems for myself and friends. I have never had one fail, and when I accidentally order the wrong one, gives me the best service ever!

Great little circulator relay that can be used in so many ways. Simple, clear wiring diagrams, extra fuses, indicator lights make for a clean installation. Have used these for years.

Replaced Argo with Taco...very happy. Quieter, it doesn't click loud when calling zones.

I'm a homeowner whose twenty-three year old Argo AR842 four zone switching relay stopped working. I suspect the so-called ice cube block that provides power to the four circulators blocks failed

Very easy to install. It replaced a 30 year old version that finally failed. Looks well made and had good installation instructions.
