Wiring Honeywell V8043E, replacing Taco valve

Hi,

The previous owner of my new home replaced one of the Taco Zone Valves with a Honeywell V8043E 2-wire valve, but never connected any of the wires. There are 4 wires, 2 red from the aux and an orange one and a yellow one from the motor itself.

I have two questions:

1) The official honeywell manual states that these are the "Yellow leads" and never distinguishes between the yellow and the orange wire. Since the system was designed for Taco ZVs, there are three wires that I need to connect to the honeywell. Which "Yellow lead" do I connect to which wire? One of the wires is supposed to go to the thermostat, and the other is supposed to go to the power supply.

2) There are two red wires, one of them was taped off my the previous owner. Should I just ignore that one?

Here is a photo: http://i.imgur.com/b1MiuWj.jpg

Thanks in advance.

I hope not a friend or relative, but the previous owner wasn't too bright...

It seems that he removed the actual wire leads that the valve comes with. Those leads are spliced onto the yellow and orange wires.

I don't have time right now to explain in detail, but there is no 'polarity'. Pretend the motor wires are both yellow.

The Taco valves have terminals 1, 2, 3

If you tie one red and one yellow together, they become terminal 2.

The other yellow call terminal 1

The other red call terminal 3

Clearly, you know your way around these systems extremely well, because that was an awesomely simple explanation!

Here are the results: http://i.imgur.com/LFHHGH7.jpg

It was as if you were there guiding my hands.

Unfortunately, even though the zone valve was opening and closing based on the thermometer, the furnace wasn't turning on. I double checked the relay and realized that the green wire had become disconnected.

And forgot to mention: It wasn't a friend or relative, but from what I understand, he was a plumber! So... I dunno if that's better or worse

Thank you again, from me and my family!

He probably disconnected those little colored "hoses" to see if any water would come out. Probably surprised the heck out of him to find that they are filled with copper wire.
