We at least need to know whether it is a gas or oil system and do you use the boiler for domestic hot water or not. Is this a new installation or are you replacing the valves?

It's new

It's oil heat boiler for domestic hot water . It is a new installation. I'am using a Honeywell Triple Aquastat relay line volt burner control with Taco zone valves.

Now that information is helpful. You will need a Honeywell AT72 transformer (or equivalent) to power the zone valves. You should bring the thermostat wires down to the zone valves and connect one side of the thermostat to terminal #1 on the zone valve. Then take a 2 conductor wire from the valve closest to the transformer (for neatness) and connect it to the remaining thermostat wire with a wire nut and terminal #2. Take the other end back to the transformer. It doesn't matter which wire goes to which terminal. Then use a 3 conductor wire and go from zone valve to zone valve connecting 1 wire from the loose thermostat wire with the wire nut another to terminal #2 and the third to terminal #3 until all three valves are wired. Then from the valve closest to the aquastat (for neatness) run a 2 conductor wire from terminals #2 and #3 down to T and T on the aquastat. Bingo.

And DO NOT forget to set the heat anticipators in your thermostat (if they are not digital) to .9 amps.

Still need help

Hi Ken, Thanks for your help for sure. But I don't understand the second part. I'am going to try diagram here. Maybe this will help me. Zone value three is the closest to the transformer and Bolier control. I understand that you want me to run two wires from the bolier control to zone value three as this is the closest one. Do I connect all the white to terminal 2 in a row and then run it back to the transformer. Do I connect all red wire in a row. If this right. Were does it connect to. Do I connect the other white thermostat wire to #2 on the zone values. Hi If you have the time and the best time to call you. I will gladly call you. If you don't mine. You can e-mail at ba4ic@yahoo.com. I figure I have about two the three weeks before I need to use the heat. I'am keep working on it. Hope you can fine the time. Also Hope you understand this. The only reason I have to make is that I burn out the thermostat control on the boiler control. I'am using cheaper control before I hook up the new one. As I preview this. It' not looking like I set it up on the postThanks Bill

Your description sounded exactly right. I couldn't understand the diagram. The only problem with one valve being closest to the transformer and the control is that you end up with 3 wires under a couple of terminals and it gets a little tough to do a nice job without shorting something out or having a wire jump out from under a terminal.

Hi, A few question Thanks.,

Hi Ken, I understand that the one thermostat wire goes to #1. The other one coming from thermostat wire get all tied (White)(Is This Right) together and does this go to c on the transfomer are somewhere else. The red wire that goes on #3 to all the zone valves. Does that come off the P on the transformer are somewhere else. Now the white wire that goes to the #2 on all the zone valve were does this go. I do Have to get power to the zone valves. Using the the red wire on #3 from the transformer.Is this right. You said once I do this. All I have do Is run the red wire to the T and white wire to the T on the B control from the closest zone valve. If you don't understand. I was wondering If you fax a diagram to me of the wiring. E-mail me if you can. I will gladly pay you for your time.
