when: The temperature spread from the setpoint is
equal to or greater than: the setpoint plus the 1st stage
deadband (step #6, page 12), plus the 2nd stage dead-
band. This 2nd stage deadband is fixed at one degree
and is not adjustable.
The low speed fan for heat or cool is turned on when:
The temperature spread from the setpoint is equal to
or greater than: the setpoint plus the 1st stage dead-
band (step #6, page 12). This 1st stage deadband is
adjustable from 1-6 degrees and the default is two
degrees.

The temperature spread from the setpoint is equal to or
greater than: the setpoint plus the 1st stage deadband
