QA CONTROLLER
AUTO
Press the AUTO key, “A” is shown in digit one on the display. Now press COOL, FAN or EXHAUST (it is
not usual to operate the unit in AUTO EXHAUST).
The “set” temperature is displayed for 5 seconds. Whilst the “set” temperature is displayed, alter to the
desired setting. To redisplay the “set” temperature press the << key.
The fan speed is automatically adjusted to maintain the desired temperature level. The greater the
variation between the ambient and “set” temperatures, the faster the fan speed and greater the cooling
effect. The fan will come on when the temperature is 1 degree below the set temperature.
When the ambient temperature reaches 3 degrees below the “set” temperature, the fan switches off. The
pump continues to operate for 1 hour after the fan has switched off. After one hour of ‘no fan operation’
the system shuts down.
A temperature that is set at an unrealistically low level will not be achieved, due to the limitations of
evaporative air conditioning. A low temperature setting causes the system to operate at maximum fan
speed. continuously.
If either “AC”, “AF” or “AE” are displayed and the fan is not operating, the system is active and will
automatically switch ON when the ambient temperature reaches the “set” temperature.
If only “A” is displayed, the system is in AUTO Mode, but not switched on.
The Timer operates in AUTO Mode as well. The system switches on, only if the temperature rises above
the ‘set’ temperature, and only once the Timer period has elapsed.
The temperature displayed is accurate for the purpose of operating the AUTO feature of your air
conditioning system. Do not obstruct the ventilation slots in the keypad base as this may cause an
incorrect temperature reading.
BUSHFIRE MODE
This mode is activated by pushing the “COOL” button twice. The fan remains off so that smoke will not be
introduced into the house. The pump circulates water keeping the pads wet. The periodic drain cycle will
function as normal.
To operate this mode:
•
If the system is operating in COOL mode. Press “COOL”. The “C” on the keypad display will
change to a flashing “P”. The fan will turn off and the pump will continue to circulate water.
•
If the system is off. Press COOL / COOL. The display will show a flashing “P” and in approxi-
mately 60 seconds the pump will start circulating water keeping the pads wet.
To return to “COOL” mode press the “COOL” button and the fan will come on. The “P” on the display will
be replaced with a “C”.
AMENDING THE WATER MANAGER PERIODIC DRAIN TIME
The Water Management System has a default five hour drain cycle. This five hour drain cycle is adequate
for most water supplies. Consult your dealer for advice.
With different water qualities it may be necessary to vary this cycle as follows:-
Press the AUTO key and keep it depressed. Press the TIMER key until the required drain cycle time is
reached, and release the AUTO key. Press the OFF key. The periodic drain cycle has now been altered to
the displayed time.
Do not adjust the periodic drain cycle to an unrealistic high number. Regular drain cycles are required to
maintain water purity and cooling efficiency.
