Title: Defective Unit
Review: It would be a great unit if it worked, and it does in Celsius. Set to Fahrenheit, the difference (from a reference temperature) is off by 32 degrees. Since F = (9/5)*C + 32, it looks like either the firmware or a memory location is defective. I e-mailed ATD, and they e-mailed their Chinese supplier. They say the units are OK, so it looks like a Quality Assurance failure. I offered to send the unit to them, but they suggested I return it to the people who sold it to me.I'm returning the unit for replacement. If the new unit works, my review will improve._____________________Got a replacement unit, same problem. Celsius works perfectly, but in Fahrenheit the unit thinks the difference between 70 degrees and 70 degrees is 32 degrees.If ATD did quality assurance and fixed a few lines of embedded code, the unit would be first rate.
