Hello, I have a honeywell zone valve V4043h that I would like to wire up with a salus room thermostat to a boiler which has a volt free terminal. The stat on it's own works perfect with the boiler however when I'm trying to hook the valve in it doesn't work. the stat has two wires that connect to the volt free boiler - N.O normally open and COM. I connected the COM from the stat to the boiler's volt free L (which has about 40 VAC). and the N.O from the stat to the BROWN from the valve. The Blue from the valve to N. The GRAY and ORANGE I connected to each side of the volt free terminal. However when the stat calls for heat the valve motor does not respond. How can i make it work?
Thanks
