Is there an easy or hard way to disable the circuitry for the indoor blower current transducers? I am aware of the kit including the 1U4 board, but there must be an easier way! Trane says no, but I'm certain that someone out there has had to retro a VFD into an existing system. I could restore the old contactor if need be. But the owner would like to have the VFD leypad active at all times. I remote-mounted the new Yaskawa keypad to the front panel for his accesiblity. The unit is ridiculously "touchy" now, and will lock out on CE anywhere from 5-60 minutes of runtime. The motor is fine naturally
I suspect a "backkick" from the drive perhaps or something like that. I could mount huge chokes on the input, but previous experience tells me that that is a very expesive gamble. Any ideas?
