Question:

Zone valves with aquastat?

I threw a birthday party last night, all went well until 2am when a crazy (drunk!) lady cut all the wires from my heating system (i guess as a prank??? dunno, she is never invited back). I have everything up and running when using one thermostat and connecting the thermostat wires (red directly to tv, Brown directly to W, and white directly to T) and not using the two Honeywell zone valves (model number V8043F. How do I connect those two zone valves to the L8148E aquastat?The valves have on bottom Th-TR, TH and TR and the two top screws are labeled end switch.If you need photos I can take them :)Thanks in advance!

The zone valves should have 4 wires, 2 yellow and 2 red.The yellow wires are connected to the 24 volt thermostat circuit in a series. The corresponding thermostat turns the motor on, opening the zone valve, closing the end switch and turning on the boiler and the pump. The red wires are the end switch wires. They are just wired together in parallel and anytime at least one opens, it turns the boiler/pump on. Now, you must have one of the Tstat wires going to the boiler, when it calls for heat, it turns the boiler/pump on. You probably have the zone valves locked in the open position. So you will have heat all over the house but just not as much control as you had when you were running individual zones. But, you know what? Your system would be more efficient if you left the zone valves locked open and ran the system from one thermostat! To make it even better, you can run the circulation pump all heating season long ( just wire it direct to 120v) and just use the thermostat to turn the boiler(burner) on when there is a call for heat. If one zone or the other is too hot, try turning a valve down on the return line(if you have valves) to balance the heat. Hope this is not too complicated and hope to help!...................................
