The two wires from 24V AC are connected as follows: one is connected to the COM port, and the other is tied to GND (circuit ground). So I think the ‘other wire’ you are referring to is the GND wire. You can access the GND pin in the pinout area.
I didn’t see any attached schematic. Can you post again?
