I would like to install a three way modulating valve, thisvalve was sold by Dwyer Instruments , with a brand name of W.E.Anderson, model 3zv20324. It has a 24volt motor that required a separate 110 to 24 transformer... this valve has three wires (1) the motor lead 24 v ;this connects to the transformer . (2) control lead that connects to the + terminal on the controller. the controller provide the power dc for 4 to 20 mA control circuit. (3) a common.. now this common I am connecting to both the other terminal of the 24v ac transformerand also the - terminal on the controller. I will include this diagram: the problem is it does not work.. the control is another Dwyer product: Love Control 16a3151. Does this wiring seem correct?
