Press and hold MODE button for 2 seconds to select Auto MODE. Use the
temperature arrow setting buttons to set the desired temperature. There will
be a 2 minute “Pre-Wet” cycle which turns only the pump on to wet the media
before the fan turns on. If the room temperature is 4°F higher than the set
temperature, the fan will start on high(Hi) speed. When the room temperature
drops within 2°F of the set temperature, the fan will enter low(Lo) speed until
the set temperature is reached. Both the fan and pump will shut off at this
point. Pressing the fan speed button can also manually set the fan speed in
Auto MODE. The pump cannot be independently turned off in Auto MODE.
