Zones are the number of areas that you want to control independently of each other. If two rooms can be controlled together, they can be one zone; if they need to be controlled separately, they should be separate zones.
Taco ZVC406 6-Zone Valve Control works with 2, 3, or 4-wire zone valves. It comes fully fuse protected, includes two isolated end switches and a built-in priority switch. Easy to read PC board layout 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.
All Taco ZVC406 Zone Valve Controls are made in the USA, UL and CSA listed and protected by an extended 3 year warranty.

Neat and Tidy
from Newton, MA
I purchased a 4-zone relay to consolidate several pump zones onto a common variable-speed circulator. Not a lot one can add to what is said about these ubiquitous Taco controls; they are as advertised and make your wiring jobs neater. Let me re-phrase. You can always do a sloppy wiring job no matter what controls you use. The Taco line removes your bad excuses. :)

Wish everything was this simple.
from Anchorage, AK
This unit does exactly what it says it will do. My heating system is three zones, plus an in-floor radiant system. The control wiring for this systems was a maze of cable, relays, and guesswork. Seriously needed replacing.The Good:Simple, clean wiring.Zone indicator lights let you tell at a glance what zone is calling for heatIncludes transformer and relays so that you can bypass your internal boiler controls (if desired)Simple screw down connections for control and power wiring.Tech support was very helpful and replied quickly.The Bad:The manual could be a bit more clear. Need to review the manual while looking at the circuit board to get the full picture. I actually contacted Taco tech support, then found the information I was looking for printed on the circuit board.Access holes do not prevent dust from entering unit.The Ugly:Working clearances internal to the unit are very tight. Need to be careful about wire routing to ensure a clean install. Ensure and test that power is off before working on unit, even connection of low voltage. 24 volts can kick up quite a few sparks.
