Help with low voltage wiring

targetman Member Posts: 105
I'm currently installing an Argo AT using the Argo AZ-4P control. It's a replacement for a small house and the HO wants to use the two existing zone valves. I don't have much experience with zone valves but I said ok and bought the AZ-4P. The existing zone valves are Honeywell V8043F models. I would like a little verification of the terminal wiring. Argo control zone 1 has terminals T-T for stat and terminals 1 2 3 4 for zone valve. The Honeywell zone valve has five terminals, TH-TR , TH , TR , and end switch. I guess I'm just not getting it.
