I’ve set the 202U up exactly the way pictured in the image from the website I supplied. Namely, I have an external 24V power source connected and the garage door wires are in the COM and the B/O ports. All dim switches are set to “off” to give a pulse to both ports. The garage door is functional and plugged in. Both remotes are programmed (and i tried both relay ports). Unless you have other troubleshooting steps to offer, I can only conclude that the unit is defective as nothing happens when I press the remote buttons (other than the light interior to the unit lights up, showing that it’s receiving the signal).
Any ideas, or should I return?
