Taco ZVC406-EXP-4 is a 6-Zone Valve Control (Expandable up to 20 Zones). This model works with 2, 3 or 4-wire zone valves, is fully fuse protected and includes two isolated end switches and a built-in priority switch. The easy to read PC board layout of the Taco ZVC406-EXP model eliminates 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.
All Taco ZVC406-EXP Zone Valve Controls are made in the USA, UL and CSA listed.

Taco ZVC406-EXP-2, 6 Zone Valve Control (Expandable) w/ Priority & Pow
By j-m Grebenc (from Broomfield Colorado) on 11/2/2012
The controller was just as advertized. It made a very tuff job easy. It. took me about 45 minutes to hook up boiler, thermostats, 6 actuator valves, two circulator pumps and main power. Easily lends itself to a very clean and professioinal look. They ship this thing in pretty much bomp proof packaging
