Irwin,

The PA temp calibration is, as Don already stated, in the manual.

Just wondering, do your fans actually run?

The fans can be tested  in de menu: KPA3.
If set to 'PA nor' then the fans are temp controlled.
If you turn the main dial, PA Fn1 - Fn4  will come on the display, You 
should hear the fans running.
