$

AMS

Smart LED display panel shows control functions and also shows error code in case of a malfunction.

Efficient trapeziform Inner groove copper tubing compared with traditional copper tubing, it allows more refrigerant flow, improvs heat exchange efficiency and lowers power consumption while keeping the same capacity output level.

Precoated Hydrophilic Aluminum Fins of indoor coil to protect the coil against corrosion and to allow easy and quick removal of unrestricted condensate water between the coil fins to increase airflow, improve heat exchange efficiency and accelerate cooling process.

IAQ

The indoor unit is fitted with a fresh air knock out panel that can be utilized to introduce fresh air into the room. This helps prevent the build of stale air and enhances air quality in working environments and enclosed applications without natural fresh air supply.

Efficient anti dust washable aluminim air filters for clean and healthy air.

Superior air distribution performance : Three fan speeds with external static pressure up to 40 ~ 100 Pa as per the model to satisfy air flow and static pressure requirements to suit various applications.

Optional Smart Link central Control to monitor from a center point, the operation of number of ducted indoor units in the same project site. This feature is particularly helpful in large office applications and hotels.

Standard Smart LCD infrared wireless remote control with complete control functions built in the control system to ensure efficiency at all operating conditions.

ECO function for energy saving and comfortable healthy sleep which automatically changes fan speed to low speed and controls both setting and room temperatures.

Programmable timer for easy on and off selection with energy savings including off timer, on timer, off/on timer and on/off timer functions.

Independent Dehumidification mode whichdehumidifies the room efficiently, but not lower the temperature so obviously as cooling operation.

Patented centrifugal blower, elephant ear propeller, new heat exchangers, improved Air Management System (AMS), and quiet compressor.Statically and dynamically balanced fans for quiet operation.Minimum vibrations with strengthened sheet metal parts by finite element analysis.

Auto

Auto mode which changes automatically the operation mode and capacity output according to temperature difference between room temperature and setting temperature.

Auto fan speed which changes automatically the fan speed to high or medium or low fan speed by sensing the temperature difference between the room temperature and setting temperature.

Smart Link

Key Features

Auto restart function with backup memory. When the power failure happenes during the operation of air conditioner, the microprocessor of the Printed Circuit Board will memorize the operation setting. After the power is recovered, the air conditioner operates automatically ( without remote control but after elapse of compressor safety time delay ), according to the previous operation settings.

3 (three) minutes safety time delay between compressor turning off and turning on for compressor protection against cycling.

Anti-freezing protection of indoor coil when the air conditioner is operating in cool mode with excessive dirt on the indoor coil and / or clogged air filters and / or low ambient temperature operation of cool mode.

3Min.

AntiFreezing

High temperature protection of outdoor coil when the air conditioner is operating in cool mode.This protection is only available for heat pump system.

Hi Temp.Protect

Cool

Defrost protection of outdoor coil when the air conditioner is operating in heat mode at very low ambient temperature.

Cold draft protection when the air conditioner is operating in heat mode to prevent cold air blowing out at the beginning of heat mode which avoids the discomfort to the user.

High temperature protection of indoor coil when the air conditioner is operating in heat mode.

Hi Temp.Protect

Heat

Motors Auto reset – internal thermal protector of indoor

and outdoor fan motors to protect motor windings against excessive current.

Smart self-diagnostic function for malfunctions detection for easy fast service and maintenance.

Smart Refrigerant leak detection by sensitive sensors mounted on both indoor and outdoor coils for easy fast service and maintenance.

Drain pan is designed to protect against rust, to minimize wet surface and residual water during off cycles and to inhibit bacteria growth that may cause smells.

DurabilityAnti-rust, weather proof and long life indoor unit sheet metal parts made of chemically treated and zinc coated ( galvanized ) sheet metal.

Optional coated aluminum fins of outdoor coil for coastal applications to protect against corrosion.

Anti-rust, weather proof and long life outdoor unit sheet metal parts made of chemically treated and zinc coated ( galvanized ) sheet metal.

Powder painted casing of outdoor unit with prefect adhesion of highly resistant ployester paint 60-80 microns thick, which is electro-statically applied and baked at a temperature of 220°C.

The components of both indoor and outdoor units comply with international standards of performance and safety.

Quiet with Minimum Sound Level

Comfort with Complete Control Functions

Complete Safety & Reliability Functions

Follow Me function for smart wired control of comfortable temperature. With this technology, an efficient temperature sensor is built in the wired control just like the air conditioner is following wired control.
