Welcome to the forums.

How many wires do you have from the thermostat to the zone valve area ?
A Honeywell zone valve should have two yellow and two red wires.
The thermostat would connect into the yellow wires and a transformer.

Pictures of your zone valve wiring would be helpful too.... How to insert pictures.
