Thanks for the info. The weird part about it is that it only seems to do this so far in the morning. It flashes the whole way to work the. After work it works normally with only the red dot showing when no brakes applied

The Triflex # C24VV sometimes does need to be reset occasionally. Try unplugging it and plugging it back in after a few seconds and it should work again.

Otherwise you have a short between the black wire and the red wire and your controller therefore is thinking you have the brakes all the time. If you can check the connections between the two circuits there might be exposed wire between the two and that's why you are seeing the issue.

I also attached a help article on troubleshooting brake controller installs for you to check out as well.

That has to be a condensation issue since the problem only happens in the morning which most likely is related to extra moisture from the night being cooler. I'd be willing to be moisture got into the controller somehow. Try bringing the controller inside with you at night and plugging it back in next morning to see if the problem persists.
