Features

Self Diagnosis
The microprocessor provides the possibility to detect and diagnose any fault or malfunction that occurs in the
system. The error will be refl ected by the blinking of the LED lights.
Advance Technology
Incorporating fuzzy logic control enables greater fl exibility in system control handling to achieve
• Powerful, effi cient and economical operation.
• Even room temperature control.
• Constant and quiet compressor operation.
• Enhanced system reliability and reduced maintenance costs.
On / Off Button on Indoor Unit
On/Off button is provided on the front panel of the unit. It can be used when the remote controller is missing or
if its battery has run out. (Note: This button can also be used for forced operation mode)
Wireless Remote Controller
• The compact LCD transmitter is able to operate the air conditioner unit within the distance of 8 meters.
• Fan speed can be set at high / medium / low / super low or automatic.
• Sleep mode auto control will gradually increase or decrease the setting temperature to provide a
comfortable surrounding for sleeping.
• Air fl ow direction can be controlled automatically.
• Room temperature is controlled by electronic thermostat.
• The real time timer allows the air conditioner to be switched On and Off automatically based on user
settings.
• Turbo mode function is available to enables the required set temperature to be achieved in a short time.
• Personalized Setting allows user to preset and store 2 groups of personal settings (including timer setting)
in the handset.
Higher Energy Savings
The inverter compressor is programmed to run at the optimum speed. This is controlled by input frequency that
varies according to the indoor load requirements.
Once the indoor set temperature is achieved, the input frequency supply to the compressor will be reduced.
Hence, less power is required to maintain the unit operation and this will consume less energy.
Improved Compressor Life Span
For this multi-split inverter system, once the unit is started, the compressor rotation speed is steadily ramp up
or down based on load requirement throughout the operation. This control method gives the compressor motor
a smooth operation. It helps to reduce the wear and tear of the compressor motor. In the long run, the life span
of compressor is increased.
Overheating Protection (for heat pump unit only)
In case the internal and/or the external temperature are too high, or the fi lter is dirty and clogged up, the
refrigerant may be overheated. The compressor will reduce its running speed in order to lower the temperature
of heat exchanger. If the temperature is still very high, the compressor will stop.
