Thanks for the heads up. I commented in that thread regarding the issue. That problem has now come up twice, and we are working to figure out what causes it. I lean toward an installation issue of some sort as we have 12 or better controllers out there and for us to have a failure rate of 2 out of 12 when the rest have been perfect seems very odd (I use to work in reliability, so I have an understanding of failure rates and failure modes). So something is up, and I need to get those controllers back to work on them and see what is going on. Either way we stand behind our product and are replacing the parts at no cost.
