Ok, let me make sure I understand. Right now my temperature is 43. I have the first slot set, if less than 32 - then B4 ON, the second one says, less than 22, then B5 ON, the third is set to, if more than 32, then B6 ON. when I run the parameter check, it says the third one fails? Additionally it is turning B5 ON, not B6. I just figured that if the temperature was actually more than 32, then this one would not fail, the other 2 would. Is that what you expect? When I turn it around and uncheck the option to use a third party temp file, it reports the 1st two don't match the parameters. Sure seems like a bug, but I could be wrong.
