2. FEATURES
Space Saving
Different types of fan coil units are designed to be both versatile and space saving to suit every interior design. Ceiling
concealed type for the sophisticated, luxurious floor space saving, all kind of interior decoration; ceiling exposed type for
economical and space saving installation; etc.
Zone Control
These fan coil units can be installed in different zones as each unit operates independently. Zone control on energy
saving, different comfort requirement; better air distribution needs can therefore be easily achieved.
Standardisation Of Fan Coil Unit Control
The fan coil unit controller is standardized using W1V3 I.C, which enables the selection of valve / valveless and cooling
/ heating applications. This allows the user to choose the desired application by just plugging in or removing the jumpers
at certain connectors on the PCB. The advantages of these units are lesser inventory for finished goods stock and spare
parts. For more details, please refer to General Installation guide.
Unique Features For MWM-FW Series
Easy Installation
The wall mounted fan coil unit is easily installed because of its compact size, slimness and light weight. Slim and short
outdoor unit can be easily installed even in a narrow balcony and passageway and yet have a stable profile.
Space Saving
No space is required on either floor or ceiling. This newly developed super slim design for wall mounting maximises floor
space usage and enhance ceiling appearance where ceilings are low.
Quiet Operation
Cooling comfort is improved by whisper-quiet operation which is achieved by a tangential fan.
Excellent Air Distribution
Air discharge direction can be adjusted in four directions, manually or automatically by using LCD remote control, coupled
with good air flow, the unit provides excellent air distribution.
Facilitated Maintenance Ensured
The new design cassette filter is slide-out type which can be easily removed at the air inlet grille for cleaning. Maintenance
is easy for electrical components, piping and wiring as these are all easily accessible by merely removing front plastic
panel.
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. Air flow 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.
Slit Fin
The unique Hydrophilic slit fin has greatly improved the air flow and the contact surfaces with the air thus to boost the
cooling capacity.

Unique Features For ACK-AW/BW Series
Built In High Head Drain Pump
The unit comes with a built in high head drain pump. Condensate water can be pumped up to 700mm and drain out
smoothly.
4-way Air Discharge And Air Swing
These features greatly improve the air distribution in the conditioned space.
Wireless And Wired Controller Option
Wireless Handset is the standard controller. However if wired controller required, Netware2 & SLM3 wired controller is a
wise choice(optional).
Unique Features For RCM-DW Series
2-way Air Discharge And Air Swing
The 2-way air discharge couple with the air swing function, provide better air distribution in the conditioned space.
Easy Maintenance
The air filter and components can be easily accessed from the bottom of the unit. This make servicing and maintenance
become a simple task.
Wireless And Wired Controller Option
Wireless Handset is the standard controller. However if wired controller required, Netware2 & SLM3 wired controller is a
wise choice(optional).
Unique Features For ACC-CW Series
Elegance And Prestige
As the unit is installed above the ceiling with only the supply and return air grille exposed to view, the air conditioned space
will appear as elegant and prestigious as a centralized air conditioned area.
Evergreen Design
This unit will never become obsolete as the unit is completely concealed away. Interior decoration for maximum aesthetic
beauty as well as interior design is easily achieved.
Superior Air Distribution
As the conditioned air can be distributed to every corner of the area by air duct, this will ensure more pleasant living
environment, thus provide extra comfort to the occupants.
Optional Duct Accessories
The optional duct accessories makes the ducting and installation work so easy.
Wired Controller
Netware2 & SLM3 wired controller offers simple and flexibility in controlling the unit.
Unique Features For ADB-BW Series
Superb Air Distribution
These units are designed with high air flow and static, enables adequate distribution of air to the desired space. Providing
comfort to every corner of the room.
Reliability
The structures are strong and robust to ensure the product operation life.
Versatile
Multiple rooms can be cooled together by just using one unit of ADB.
