3.3.1 Cooling
The recommended maximum return-air temperature is 105°F (40°C) and maximum dew point is 59°F
(15°C). The recommended minimum return-air temperature setpoint Dry Bulb is 85°F (29°C).
Operating outside this envelope can decrease equipment reliability.
NOTE: If running in supply-air control, the minimum supply-air setpoint is 68°F (20°C), and the
maximum supply air temperature is 80°F (27°C).
NOTE: When running above 77°F (25°C) supply air temperature, the superheat readings on the
refrigeration circuits may be higher than 7.2°F (–14°C). The EEVs will run out of stroke and limit mass
flow, which will result in higher than normal superheat.
