* PremierLink controller cannot be used with Staged Air Volume (SAV™)
2-speed indoor fan motor.
**To meet new DOE mandatory efficiency requirements for U.S. installations,
2 Speed Motor (SAV) system is required. 48TC*M models for installation
in the U.S. meet DOE efficiency standard but 2 Speed (SAV) is not required
or available.
