The pair of red wires coming out of the 2 zone valves are the end switch. Each individual red wire should be attached to one from the second valve, than from there to the "T-T" of the relay on the boiler. It would be to where you normally hook the thermostat for a single zone system. The yellows are the leads to the motor. I'm not sure what transformer you are using but if it is the 24 volt transformer in the boiler be careful you don't overload it. Hooking up 2 zone valves should be ok. Nevertheless one yellow wire from each zone valve would go to common of the transformer. The other terminal of the transformer goes up to the "R" terminal of the thermostats. Than the "W" wire from the thermostat gets wired to the remaining yellow wire for the matching zone valve. You have to make sure the heat anticipator in the thermostats are set to the ratings of the zone valves. If you have Adobe Reader the link below may work and you can see a diagram direct from Honeywell. If not I can fax you a diagram if you need it.
Hope this helps.
Is this the right way toi do it ? and what is the common on the transformer

Ok..since we have no idea what the original question was (from Jan 2000?)...and we have no idea what kind of system you are even talking about...maybe you should just ask your own question?
Or clarify exactly what you are trying to do? Sunday may be kind of slow for responses though...it usually is.
