The Set Temperature Display Area shows the temperature the unit is
set to achieve when operating. This temperature can be increased or
decreased using the TEMPERATURE UP & DOWN buttons.
In order to achieve the best results we recommend that a setting of between 22C and
24C will give the best results in terms of room comfort. Constant changes in set tempera-
ture will not give better comfort but will increase energy consumption. Operating the unit
with an abnormally low set temperature in cooling or abnormally high set temperature in
heating for extended periods may also cause erroneous operation.
The Fan & Louver Display Area shows the fan speed and also whether
the automatic swing louver is operational.
To start or stop the swing louver mechanism press the SWING button. All four louvers
operate simultaneously and can not be controlled individually. This function can only be
set when the unit is running.
To change the fan speed press the FAN button when the unit is running. This will scroll
between high, medium, low and automatic fan speeds.
Swing Louver
Low Fan Speed Medium Fan Speed High Fan Speed
Automatic Fan Speed is shown by the display continually changing from low to me-
dium to high fan speed.
In order to prevent malfunction it is strongly recommended not to use the low or
medium fan speed settings when using the unit in cooling or automatic modes with a
set temperature below 21C or in heating or automatic modes above 25C. Under cer-
tain conditions the units internal controls may over ride the fan speed selected by the
user.

The Output Device Display Area is designed to show which of your sys-
tems internal components are operating at that moment in time, except
for the Indoor Fan and Swing Louver which are shown separately in the
Fan & Louver Display Area. It can also display if the keyboard lock is
set.
The Internal Drain Pump is used to remove condensate water produced during
cooling, automatic and dry modes from the indoor unit.
The Reversing Valve is used to reverse the flow of refrigerant in order to allow
the unit to heat instead of cool. This is lit in heating mode.
The Outdoor Fan is used to reject heat from the room in cooling or dry modes or
collect heat from outside in heating mode.
The compressor is used to pump refrigerant around the system to allow the unit
to heat or cool. It is located in the outdoor unit.
The electric heat symbol is used to show when an optional electric heater device
is energised. Your Highcool unit does not have this heater and if it is displayed
you can cancel it using the HEATER button. It has no effect on your unit.
The Defrost Symbol shows when the unit is in heating but has stopped to melt
any ice formed on the outdoor heat exchanger. This will happen from time to
time to allow the system to operate efficiently.
The Keyboard Lock is used to prevent unauthorised access to the controller.
When it is lit none of the keys on the controller can be used. This allows the
operator to set the units operating mode and start / stop times then prevent
others from interfering with the operation of the system. It is enabled or disabled
by pressing and holding the RESET button for six seconds.
