I am havng trouble figuring out the wiring schematic. There are 4 wires that connect to the valve. I have the correct supply of power from the transformer.
See attached. I believe I have the 24v common and the 24v hot hooked up as I can head an audible click of the valve when my pid supplies the power however I am not sure what to do about the 24v thermostat/pressure input.
Current setup is 110V to PID output 24vDC>>>SSR
110V hot and common from SSR>>>Transformer
24VAC from Transformer >>>Valve.
The transformer must be powered continuously to supply power to the valve internal electronics, not through the PID.
The PID output connects in place of the thermostat as per drawing.
