Does anyone have an issue when activating switches, for example, activate Switch 1 (on port 1), but another switch randomly activates at the same time and stays active until power is removed? I had the TIU with wifi interface, all was working well. I replace with the WTIU, of course I can only utilize 1 of my TIU's, I have 2, but can't even throw switches correctly on the AIU I can control. The first time it happened I reacted too slow to removing power and actually burned up 2 switch motors.
