Is the "passport I/O control unit" analog or digital?
How many power leads does the fan motor have?

What is the model and serial numbers of your passport I/O control unit?

FAN
Fan-speed operation is automatic, allowing fan speed to decrease as set-point temperature is approached in the Cool Mode.
The fan operates at low speed when set point is satisfied.
Normally the automatic fan speed operation is reversed in the Heating Mode, however, you can program the fan to operate the
same as in the Cooling Mode.
Press the Fan button to select manual fan speeds if you want to override automatic operation. You can program the fan to run
only during a cool or heat cycle, otherwise the fan runs constantly.

I had a similar problem with Marine Aire. Pull out the manual, check the codes for each parameter, somehow some of mine had changed, when I reset them, fan worked normally again.
