Don't have a picture

but a recommendation. I use the Taco zone valve control boards. (Model ZVC404) They make it easy to wire complicated zone valve applications. You wire the t/stats to the top terminals and the zone valves wire into the corresponding bottom terminal. They even have lights on the side to let you know when the tstat is calling and on which zone and when the zone valves are open. Just did one last week. Took out a rats nest of wires and left the Homeowner with a good feeling and a nice neat job. Other brands are availible. WW

I just wanted to know because i am new in the feild and most systems i see have the nest of wires and i need to know how they are wired.If you could explain starting from the transformer thru please.

Aquastats and thermostats....

...simply make/break the 24V transformer circuit to the ZV. When the aquastat makes, 24V is sent to the ZV and energizes it to the open position. As the ZV reaches the full open position, the end switch makes and turns on the circ through the circ relay. All ZV end switches are wired in parallel to the circ relay T-T terminals.

Make sense?

Zone Valve wiring

because you are new to the trade I will send you a complete set of diagrams and procedures for zone valves for free. Just e-mail me your postal mailing address and it will be a done deal. My e-mail is gastc@cox.net, look forward to serving you.

Here is a drawing

depicting multiple Honeywell Zone Valves with thermostats. All you are doing is using the aquastat as the thermostat. In other words, the aquastat will make on temperature fall and actuate the zone valve which will in turn fire the boiler via the end switch wires or terminals 3 and 4 in this drawing. Hope this helps.

Glenn's picture

is typical of a different brand zone valve. You can still use his picture though. Terminals 1 and 2 are the yellow wires on a Honeywell zone valve. Terminals 3 and 4 are the red wires.

Don't ignore the instructions packed inside every honeywell product. They will always have illustrations showing diagrams and typical installations in their instructions. If somehow you don't have the instructions you can download their instructions at their website. Try searching for the zone valve model number at http://hbctechlit.honeywell.com.

I always find it helps me to make a diagram on a blank piuece of paper BEFORE you go to the job. Make a picture of the components and how you plan to wire them. You'll find that you will be able to the job quicker, sometimes without even referring to the diagram, once you put it on paper with your own hand.

The Drawing

was done several years ago for a contractor that had the model with the screw terminals instead of wire leads. I've been meaning to update that a bit. Here is a better idea of what you have there. Hope this helps.

the good book

One of them anyway is Carol Feys " Quick and basic hydronic controls" available to the left in "Books and More" Well worth buying to review the wiring topic.
