THe websites are just fine. But once again we have the problem that the websites do NOT give a DECIPHERING table for their own plug code system!!! THAT is the PROBLEM!

With out such a chart to decipher the CODE it is impossible to VERIFY such things as HEAT RANGE. The only way to do it is to use the age old (up until about 10years ago) AC codeing system and then cross back into the plug of choice and hope for a miracle.
