I have 2 zones each with a Honeywell zone valve. (the valves have "end switch on top and TH-TR...TH...TR on bottom) I need to know how to connect the second valve. The first valve is connected to the transformer, thermostat and aquastat and works correctly. On the second I connected to the first valve by running the wire from fist valve "end switch" to the second valve TH-TR & TR with the second thermostat connected to the TH-TR & TH. It doesn't work??? Am I correct in thinking that I don't run the second valve to the aquastat as it is going through valve 1?
Thanks for any help!
