        Comments about 3 Zone Switching Relay:

        This is a great product to control your different zones/circulators and has proven to be very reliable. However, be careful using WIFI thermostats with this product as they may draw too much power off the 24 volt transformer and then cause the relay to go haywire.

                    Needed a controler as I was adding another heating zone as well as indirect water heating. Checked around for what was available and decided on this model. Worked great, very easy to install and Supplyhouse prices were great.

                                      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.
