In a particular scenario that I encountered with a low-temp 10hp application with a short lineset (the manufacturer did not provide accumulator on new condensing unit), when coming out of defrost, liquid would make it to the compressor, and result in oil pressure safety trip. After conversation with Copeland, it was determined this to tbe the cause. Initially we compensated for the lack of liquid protection by increasing superheat setting, which of course de-rates capacity somewhat). However, on an unrelated service of the equipment, we took an opportunity to install an accumulator, and re-adjust the TEV to normally accepted settings.
You are stating my case, Herefishy. Adjusting the TEV to compensate for a defrost event makes no sense, first of all.

I don't know about calling it "error". It is a matter of understanding the characteristics of the operation of the equipment / machine, and applying the controls and devices to ensure dependability and perform the task in which it is commissioned.
