Features A5LCY-E-2010
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 reflected by the blinking of the LED lights at indoor unit and by wireless handset 7-
segment display.
Technology
Incorporate PI control to achieve more precise temperature control, faster and smoother response. Enhanced
design using
Electronic Expansion Valve to achieve optimum refrigerant control as compared to capillary tube.
Discharge pipe temperature control, high pressure limit control, input current control and heat sink
temperature control to improve reliability.
On / Off Button on Indoor Unit
On/Off button is provided on 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).
Auto Restart
Auto restart function allows the unit to automatic restart as the last setting condition when the power supply is
resumed after power failure. However, the compressor will restart randomly if more than one unit is installed
and sharing the same phase of power.
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.
Night Set mode auto control will gradually increase or decrease the setting temperature to provide a
comfortable surrounding for sleeping.
Air flow direction can be controlled automatically.
Room temperature is controlled by electronic thermostat.
The delayed timer (from 1 to 9 hours) allows the air conditioner to be switched On and Off automatically
based on user settings.
Energy Saving
Equipped with energy saving selection to limit the maximum power consumption to just 700W. This feature is
also useful in preventing circuit breakers from being overloaded due to the use of multiple indoors and other
electrical devices. This new series is also designed with Standby Electricity Saving Function to reduce the
power consumption when unit is not in used.
