3 Zone's connecting to one Control Center + 3 thermostats
I have a 3 Floors with separate heat. Top, Main, Basement. I bought the house with only (1) 1/2" zone valve for the top floor. I would like to remove that zone valve and install it with a 3/4" Zone Valve, (as I have all 3/4" copper pipe) as well adding 2 addition 3/4" Zone Valves for the Main floor and Basement.
But the other problem is connecting them all to one Control Center. As of now I have 2 thermostats installed, 1 zone valve, and all connected to the control center.
When heat is called for the top floor, the zone valve opens and heat goes through all 3 levels.
When heat is called for the main floor, the top floor zone valve is closed and gets no heat. But the main floor and basement gets heat.
The basement has a thermostat, but it is not wired up, so it can not call for heat. Only getting it when either the top floor or main floor calls for it.
So this is why I want to install 3 new 3/4" zone valves. One for each level. Than have them all connected to their own thermostat and all connected into the Control Center. I was just quoted for $1000 to do this. I thought that this was high and I could try and do this myself.
Here are some pics.

I'm going to suggest you get one of these to simplify the wiring.
Taco-Hvac: Zone Valve Control
It's a zone valve control module. Using it, you'd only need to run 2 wires to each thermostat, and the wires to each zone valve. It makes the wiring neat and EASY.
Only one connection is made to your boiler TT terminals.

I agree with Dan's choice... use a Taco ZVC... piec'o'cake
It's a working valve? Leave it alone. It ain't broke, don't fix it. Chances are you don't need a ton of flow up there anyway, what's the heat loss of the space? If it breaks, and you wanna change out the valve instead of slapping a new head on it, change it then.
But do install the valves on the other two floors.
Your pump will remain wired to whatever it is currently wired to, but you do have the option to move the pump wiring to the new panel as well. That's optional.

You really don't need anything but the three zone valves and a 24v transformer. A thermostat to each zone valve and daisy chain the end switches back to the thermostat connection on the boiler.

That's true! But I just love them Taco panels... I just think it makes the wiring so much easier.
I use this drawing a lot... explains how to hook up basic system. If you need more valves, just add them to the right side. A standard 40VA transformer will easily run three valves.
(rbecks drawing is good too! and all the other types of valves are on there as well.)
This is for the Honeywell style valves with isolated end switch, 4 wires.
Hooking up the 3 wire variety like the Taco, is just as easy.

It's working the way it is now, just no properly, or I should say efficiently.

Ok, so here's my new diagram.
Now how do I label the colours? Out of my Honeywell zone valves are 4 wires, 2 red and 2 yellow. I was trying to colour it to my diagram, but cant figure it out. Does it work just as simple with positive + and negative - ?

So my current transformer/control center would be fine to dasiy chain these?
Let's back up here though... because I only just now went to look at your pics... I thought I understood what you have there, but after looking, realize that I don't...
I do not understand why that control center was used. What is running from the relay?
To where is the system circulator wired?

Sorry for the late reply. I am still planning on doing this, but now waiting for the summer. The basement loop, I just added an electric baseboard heater for temporary use.
So now back on topic. I really like that all in one unit. I am still going to go with 3/4" Zone valves.
I want everything to connect into that Taco SVC Taco-Hvac: Zone Valve Control
This is what I mean to connect everything together.
