Garage door opener Remotec ZFM-80

So I finally got the ZFM-80 to work with my garage door after taking apart a remote and soldering the relay connection to the wireless remote. However, the problem here is that my garage only takes a signal from the ZFM-80 when it’s turned on. Given the ZFM-80 has an on and off in order for me to open/close my garage door I have to push the button twice. Once to turn off the ZFM-80 then a second time to turn it on which it appears then sends the connection. So essentially I have to push it two times in order to push the command through. Is everyone else experiencing this same behavior? Is there something I’m doing wrong here? I kind of thought this was a switch that didn’t have an on/off position but rather when you activated it the device would short/close the loop for a brief moment and then disconnect. Anyone have any thoughts?
