When the cooler is in AUTO mode, it will adjust the fan speed and cooling to achieve the new

HUMIDITY CONTROL PROGRAM
Humidity Control has 2 modes.
MODE 1:
The default mode provides a maximum Humidity Limit per the set point within the Wall
Control. In this mode the AUTO control function will respond to the temperature sensor to achieve
comfort conditions in the building according to the temperature set point in the Wall Control. However
the pump will stop (and therefore no moisture is added) when the room humidity rises to the humidity
set point in the Wall Control.
MODE 2:
The alternative mode allows the cooler to attempt to satisfy both temperature and humidity,
with humidity over-riding temperature when the temperature is satisfied but the humidity is not.
The choice of which mode to use is made by changing parameter B4. See instructions below. In the
MANUAL mode no humidity control is enabled.
