Just called TT Lee, and it's on all the time. Sounds like a good topic for a

Nope! I should have emphasized "...THINK..." in my post. You
are the second person to say it runs all the time. I got the idea
that it was thermostatically controlled from the schematic which
shows a temperature sensor in addition to the bias diodes on the
PA module and that there is a third line going to the fan
assembly that looks like a control circuit. I just put 2 and 2
together and got the wrong answer. :-) Sorry about that!
