Step Button
As explained throughout these instructions the “STEP” utton is used to increment various
features such as the comfort level, fan speed or the time after which the unit will turn off.
On/Off Cool Button (Automatic Mode)
Press the utton marked “ON/OFF COOL” once and the sequence of events listed elow will
occur automatically.
1. A range of lights will appear on the display. The top light will indicate the current room
temperature. The lower flashing light will indicate your required comfort level.
2. Each press of the “STEP” utton will change your required comfort level. For example at comfort
level two (2) the unit will cool less than comfort level one (1).
3. Your unit will not operate the fan immediately. Should the unit e fitted with a dump valve the unit
will fill the water sump. Should the unit not e fitted with a dump valve the sump will already e filled
with water.
4. Next, the pump will move water over the filter pads (pre-wetting) thus saturating your pads so the
first urst of air will e cool.
5. After the pre-wet cycle is finished the pump will continue to operate and the fan will come on
automatically. The fan will adjust its own speed according to the difference in temperature etween
that inside your house and your selected comfort level.
6. As the room temperature nears the preset comfort level the fan of the unit will automatically slow
down and the num er of lights will decrease, indicating the lowering temperature. As your house
temperature rises the fan speed will automatically increase to reduce the temperature to your
required comfort level or as close as possi le. Note that the desired comfort level is not always
achieva le as the humidity of the outside environment is varia le.
7. To turn your unit off simply press the “ON/OFF COOL” utton once again.
