Taco ZVC403 3-Zone Valve Control works with 2, 3, or 4-wire zone valves. It comes fully fuse protected and includes an isolated end switch. The easy-to-read PC board layout of the Taco Zone Valve Controls eliminates the problems with incorrect wiring and the “unfinished” look of conventional zone valve installations. The sturdy screw connections add additional reliability, while the external indicator lights provide instant diagnostic feedback, reducing installation time.

Mostly Good
By Reviewer (from Michigan) on 1/24/2016
The device fails to give clear descriptions for connections and/or instructions for usage. Must be familiar with reading diagrams. Not for most home owners. (I got the explanation from electrical engineer son, and then it was easy.Would have been better if it had a power cord with it.It is actually a very simple device that seems to work well, if one can hook it up correctly.
