Taco zvc405-4, Taco 5 Zone Valve Control
By Gregg G. (from 68 Asher Ave. Pawcatuck, Ct 06379) on 8/31/2013
I just installed it yesterday and ran it threw it's course. It seemed like it all worked. We'll see this winter when it the zone valves call for heat if it all works, I hope... Well constructed.

What's the difference between this ZVC and a switching relay?
Read 1 answer
ZVC is a Zone Valve Control, intended for controlling 24V (2, 3 or 4-wire) zone valves. Switching relay (Taco SR series) is for controlling standard 115V circulators.

What else do you need to buy to install this ? transformer? etc?
Read 1 answer
The unit already comes with (2) built-in transformers (1st for zones #1-3, 2nd for zones #4-5) and has (2) standard 120V power inlets. Taco ZVC is an intermediary between the 24V zone valves and 24V thermostats, so both of these will be needed for the installation.
