Right, that's what I am saying. If the manufacturer wasn't a secret, I might be more help.

This is why Vintage Air uses a thermistor in the case on the GENIV units. That tells the ECU what the temp is, cycling the compressor accordingly so it doesn't freeze up. On the GenII units I have had to hide the thermostat so the customer would quit setting it on kill and freezing the unit.
