HOT START SYSTEM

(Heat Pump Models Only)
To prevent a cold blast of air when the air conditioner turns on in the heating mode the
indoor unit incorporates a computer controller hot start system.
The indoor unit microprocessor monitors the temperature of the indoor heat exchanger
and operates the indoor fan at a speed lower than the normal low until the heat exchanger
temperature reaches a target temperature. When this target is reached the fan switches
from extra low to normal low. The air conditioner will then operate at normal low until a
second higher target temperature is reached at which point the fan will switch to selected
speed. This hot start feature is also utilised after defrost and during the heating cycle
when the compressor switches back on after the room temperature has fallen more than
1°C below the selected temperature.
AUTOMATIC RESTART AFTER POWER FAILURE
If the air conditioner is operating during a power failure it will automatically restart in the
same mode when the power is restored.
DUAL REMOTE CONTROL OPERATION (Optional)
A second (optional) remote control may be added to the system to allow setting and
control of the unit at two different locations. This is particularly useful in two storey
applications where one controller can be installed upstairs and the other controller
downstairs. When dual controls are used the air conditioner will obey the last command
entered into either controller. Both controllers will display the same information so if the
temperature on the downstairs controller is increased from 21 to 23 degrees, the upstairs
controller will also indicate 23 degrees.

EFFECTIVE OPERATION

For best results from your air conditioner we recommend the following:-
• Do not leave open any windows or door which will allow the loss of conditioner air.
• Draw blinds or curtains over windows to prevent direct sunlight entering during the
cooling cycle.
• Set the desired room temperature to avoid excessive heating or cooling.
• Keep the air filters clean.
