Ironic this comes up today. Just the other night, I was discussing this with someone and embarrassed myself overlooking that I had the polarity on my meter reversed CN1 pins are active low. This means they are held at 24v until active (at which time the pin grounds thus creating / completing the 24v differential needed to energize the solenoid / relay coil): [image]
