New Erie Zone Valve wiring problem

Hello there,
I am having to replace an old zone valve with a new valve.

It is a Honeywell Cronotherm system, connected to a junction box which controls two valves.

here are pictures:

Here is the specs on the zv from Erie

On the supply line to the zv the black and red are hot with 24v.

The other zv already connected (not shown in pictures) is an older erie type with two red wires. Its supply line is also 4 wires (same type as supplying the other disconnected valve see picture if nec.) with the red and black hot, and the white and green tapped off with a wiring nut.

There is a line from the junction box going to the relay for the pump.

Any help on hooking this Honeywell system to the erie zv would be a greatly appreciated.

Rhap, everything we can tell you is in that install booklet... there's no way we can look at that terminal strip and tell you what wires to connect where... there's just so much more we would need to be able to see and touch...


The chances are pretty good that the thermostats are only using 2 of those 4 wires... you need to look at the other end, at the thermostat to see what those wires are connected to... do that and let us know what you find... check both thermostats... see if they are the same...
