The control keeps flashing the change panel code. It has a new pad, water to the solenoid, and the solenoid opens with 24 volts applied to it. I was told to reset the control to set it to test/reset for x amount of minutes then set it back. I tried this numerouse times for different amounts of time with no results-no 24 volts to solenoid when the control is set above the required humidity. Is the control stuck? or is there a different way to reset the control?
