Energy Saving
Total energy saved can be as high as 30% compared to the conventionally controlled units.
Efficient
McQuay DC Inverter series achieve excellent efficient with high EER & COP rating.
Comfortable
Users enjoy better comfort and quietness with inverter technology. When the environmental factors, such as
temperature, humidity, airflow and/or outside ambient conditions, are obtained and processed through a con-
trol algorithm, the compressor motor speed can be varied to optimize the cooling power to create a more
precisely controlled room temperature (i.e. less temperature fluctuation).
R410A Refrigerant (New)
Introducing the new type of refrigerant - R410A which is environmental friendly with Zero Ozone Depletion
Potential (ODP = 0). R410A also provides the higher volumetric capacity and better refrigerating effect per unit
of volume.
Advance Technology
The traditional conventional air conditioners repeat "the start" and "the stop" during the thermostat cycle off and
causes the room temperature to be unstable. Incorporating fuzzy logic control into the McQuay Inverter design
enables greater flexibility in handling the system control.
This result in:
- Powerful, efficient and economical operation.
- Even room temperature control.
- Constant and quiet compressor operation.
- Enhanced system reliability and reduced maintenance costs.
Self Diagnostic
Both indoor and outdoor LED Error Code Indicator helps to simplify the trouble shooting process. Where there's
fault detected during operation, the defect code will be to indicate the faults.
Wireless Remote Control
- The compact LCD transmitter is able to operate the air conditioner unit within the distance of 9 meters.
- Fan motor speed can be set at low / medium / high or automatic.
- Sleep mode automatically increase set temperature since room temperature is lower at night thus
achieving comfort surrounding.
- Airflow direction can be controlled automatically.
- Room temperature is controlled by electronic thermostat.
- The unit can be preset to on and off automatically for maximum of 15 hours by using timer on/off.
- Introducing turbo mode, which allows inverter compressor operates at high power and maximum
speed to achieve required temperature quickly.
