Notes:
1 . See map in next figure for dry bulb changeover.
Examples:
- Minneapolis, Minnesota is in “Region 6" and resides in “Moist” subregion, thus designation is 6b. Economizer changeover setting should be
75°F.
- Charleston, South Carolina is in “Region 3" and resides in “Moist” subregion, thus the designation is 3c. Economizer changeover setting
should be 65°F.
2 . Go to SETUP menu and input setting for parameters listed in the table above.
3 . Use the Dry bulb changeover map to determine region of country based on unit site location.
4 . Fixed speed compressor units 8°F deadband.
5 . eFlex™ compressor units 4°F deadband.
