Working Great, has lights where I can see them at a glance

Time and space saver
I purchased this unit and it arrived in less then 24 hrs., and I'm a few states away. This unit saved me time and a lot of aggravation. It is so simple to wire your connection and the price was the best, no matter where I looked. If you have multiple zone and a boiler that requires a circulator to drive that boiler, you need to purchase this switch relay.
