•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 control 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 provide 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 cause the unstable of room temperature. 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 troubleshooting process. Where
there’s fault detected during operation, the defect code will 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 fast.
