To me it sounds a lot like the board is failing. I was just wondering where you hear the faint click. I assume it is on the board and not a relay in the thermostat.

I'm pretty sure the click is the relay, but I'll have a closer listen next time. The board is brand new as well, it was replaced as I assumed the old DSI board was the culprit. I had the same situation prior to the dinosaur board.

Thanks all of you for your knowledge sharing on this!
