many features:
• The compact LCD transmitter is able to operate the indoor unit within 8 meters of distance.
• Fan speed can be set at low/medium/high or automatic.
• Sleep mode auto control will gradually increase or decrease the set temperature to provide a comfortable
surrounding for sleeping.
• The real time timer allows the unit to be switched ON and OFF automatically based on user settings.
• Ionizer or non-thermal plasma is available to create better air quality.
• 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.
