Hi all ,
I've got a second hand wp40 jebao wavemaker from a fellow reefer recently , the thing all works great and its incredibly silent , however, I cannot change the settings via the controller , anyone knows why ? When i press the mode button or the speed/feed buttons non of it works , Im not sure why , but the only the lights on the h1 setting is blinking , the rest are all off. Also , i cannot tune the durations between each wave with the knob , anyone migt know ? I tried to unplug it but nothing works
