The "auto" modes allow the bath to operate automatically in the manner described above.
The cooling "on" function eliminates this auto feature and the refrigeration is on at all
times unless the front panel switch is turned off or until some other menu selection is
made. The hot gas bypass mode selection works the same way. The "auto" function is the
default and active until off or on is selected. "On" means it is always on with no
automatic selection and "off" is always off (or cooling always on maximum). It may
desirable for different reasons to eliminate the automatic functioning; therefore, these
selections are made available either through the front panel or through the digital
communications interface.
