                          Had to add 2 zones, The taco instructions were great. Just remember that if your adding onto a system that has a domestic HW priority already you will need a zone for that... Thats why I had to get a 3 zone controller. Pex Supply is the best company I have ever bought from, FREE SHIPPING NEXT DAY..Great prices, Nice!

                                this switching relay was a breeze to install. i replaced a pair of honeywell mechanical contacts and ended up putting in a third zone for a 4 loop radiant heat zone. great price, great products. taco makes top of the line equipment. pex supply has great prices and service, way better than going to a local supply house. they are doing the plumbing business right.

                                      First time installing, easy to wire, straight forward and it works great. I like the lights that tell you what zone is running at a glance. I mounted mine away from the boiler on the chimney at eye level.

                                      If You are using zone circulators and a zone boilermate, this is the easiest set up. It will work flawlessly.
