I have poor hearing and only my wife can hear the beeping from the cerbo. I have checked back numerous times to see if relay 2 would get alarm functionality. Since this is likely not going to happen. I will look at removing the onboard alarm and install my own relay.
Here's where I need help. My setup is in winter storage and I can not get to it until spring. if anyone has an open cerbo. Please can someone see what the vdc of the onboard circuit is? I can take it from there.
