Hi Tony, yes you are correct, a short press resets the relays to 'bypass' mode (reset mode more accurately) ......AND..... if, like me you fit a power on/off switch to the ATU-10 which is wired across the link to the batteries.? In my boards that's? 2 pin 0.1" header pins.
so, no RF input, short press to reset relays, switch off the power switch.
From memory a very long press just puts it to sleep? RF in will activate it again??? I don't have mine setup here to verify.
