4 .MEMORIES After turning off, the operation status; air outlet volume, air direction selection, set temperature and some other control settings, will be automatically stored in the memory. Operation resumes with exactly the same setting/configuration as it was prior to shutdown, when unit is turned on. HIGH EFFICIENT REFRIGERATION The use of high efficient, energy saving, and low noise rotary compressors produced to world class standards by Mitsubishi and Toshiba, has been adopted in Holtstar air conditioners. CONTROL BY TIMERS Switching on or off of the unit can be programmed or preset in advance within 12 hours. AIR EXCHANGE DEVICE This device helps to discharge the dirty air in the room and take in the natural fresh air outside so as to keep the air clean and fresh. INDEPENDENT DE-HUMIDIFYING This function enables the swift removal of the water vapour content in the air within the room, both in rainy season and humid weather. INTELLIGENT DEFROSTING The initiation and process of defrosting is controlled by micro processor to ensure effective heating conditions. MULTI FOLDS EVAPORATOR This evaporator is composed of durable and high conductivity internally-threaded copper pipes, sandwiched in hydrophilic aluminum fins for improved heat exchange. The four five fold/faced evaporating surface allows for a compact design, yet greater heat exchange surface area and thus greater cooling efficiency. It also eliminates the air flow noises emanating from the cross flow fan wheels. ENHANCED AIR DELIVERY AND NOISE REDUCTION A number of unique design considerations accounts for the extra quiet operation and enhanced air delivery of the holtstar air conditioner, both in the indoor and the outdoor units. The sawteeth design of the fan blades (in the latest model) greatly reduces the vibration noises at the end of the vortex, and the operating noises of the outdoor unit. Noise reduction is further enhanced by the large diameter centrifugal fans design, which allows for increased air intake at relatively lower operating speeds. Again, the unique air duct design enhances larger air delivery volume at lower operating noise levels. The low noise rotary compressors of the outdoor units contributes immensely to the achievement of quiet operation. 260V 140V SLEEP MODE AUTOMATIC CONTROL Once the sleep mode is activated, the temperature is automatically adjusted and controlled. During refrigeration process, the preset temperature will rise by 1 degree C for two hours of continuous running. During heating process, the preset temperature will drop by 3 degrees C for 3 hours of continuous running. By so doing,the room temperature is always kept at a comfortable level. W I D E V O L T A G E D E S I G N [ I N V E R T E R T Y P E A I R CONDITIONERS] Unit can still function well within a voltage range of 160v 260v, a steady level of voltage delivery void of frequent fluctuation, however, will guarantee safety of use and minimize failures. This can be achieved with use of stabilizers. COLD CATALYST TECHNOLOGY The cold catalyst serves to sterilize and remove unpleasant odors. It can completely degrade the methyl oxide in the room air that might cause cancer disease. It will also effectively remove the odd odors like those of methyl hydrosulfate, ethyl mercaptan, etc. Compared to the optical catalyst, the cold catalyst has the advantage of recycled use without going through regeneration process. CORRUGATE HIGH EFFICIENT FILTER SCREEN This super filter screen is easy to remove for cleaning, highly effective in mold prevention and anti-bacteria, ensuring the healthy environment in the room. INTERNAL THREADED COPPER PIPES These internally threaded pipes raise the heat exchange efficiency by 30-50% than in the ordinary copper pipes, as the refrigerant flows faster and more forcibly inside the copper pipes, thereby reducing the energy consumption. HYDROPHILIC ALUMINIUM FINS The heat exchange of Holtstar air conditioners is facilitated through the use of Hydrophilic aluminum fins, which reduces water retention on fin surfaces, enabling the film-like condensation of return warm air and thus eliminating clogging of fin surfaces by bridging water droplets, and improving the heat exchange rate by 40%. HEALTHY IONS The air in air conditioned environments is usually characterized by excess positive ions, which could lead to nausea, headaches etc. Holtstar air conditioners have inbuilt super quality brush-type ion generators, which neutralizes this condition by means of ionization. The ion generators produce large quantities of anions to neutralize the positive ions in the air so that the room air is made clean, fresh and full of active oxygen suitable for human consumption. THREE DIRECTIONAL SWINGING PATTERN AIR DELIVERY TECHNOLOGY There are air delivery direction and air swinging buttons on the remote controller, by which the fixed directional air delivery can be realized. A three dimensional air delivery pattern can be selected using this medium to suit the convenience of the user. Air direction is facilitated in the evaporator through the combined action of the vertical sweep/guide vanes, the dual horizontal sweep flaps and of course the blower wheel which produces the upward thrust. This design ensures a swift and even distribution of air without creating any discomfort of air thrust on the user.

5 BIOLOGICAL ACTIVE ENZYME A sophisticated biological filtering technology is applied in the design of the air filtering system. This enables the filtering channel to effectively kill the gram-positive germs, gram-negative germs, funguses, phycovirus, saccharomycetes, viruses etc with a sterilization rate as high as 99.9%. HANDY REMOTE CONTROLLER The remote controller is designed stylishly in the form of a handy mobile phone, with a led display for convenience of use. It is user-friendly, with a soft-touch operation and special luminous buttons that enable easy operation in the dark. DYNAMIC VFO LED MULTI-COLOUR DISPLAYS This comes with a stylish and fashionable colourful display design that complements interior decorations/outlook and distinct demonstration of operational status details. ATTRACTIVE APPEARANCE AND EXQUISITE DESIGN Front panels reflect an embodiment of beauty, compactness and simplicity. All models come in compact and attractive forms, occupying less space, presenting higher taste and grace..intelligent CONTROL TECHNOLOGY A number of intelligent control technologies are adopted, such as the sleep mode automatic control, automatic defrosting and a combination of others culminating to economic energy saving operation, etc. these intelligent control technologies make the operation of the machine user-friendly while providing great comfort of conditioned atmosphere. They fully reflect the care and personalization of the HOLTSTAR DESIGN.
