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.
