So I've been trying for the last three hours to get the fans in the utility room to come on. Hot as hell in there. Measured surface temps on electrical cabinets, was 130-135 degrees. So hot in fact, it was tripping the breakers in said cabinets. So, after much deliberation and searching, I found the frequency drives for the fan motors, disabled the imax controller, and increased the ramp up time to 50 seconds. And Voila! Fixed the problem. Nice breeze in there. I'll be really happy if it stays fixed. Have lots of work to do.
