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.
