Features
Save Energy
This decentralized, year-round heating and cooling system consists of a two-pipe closed loop water circuit, through
which non-refrigerated water circulates continuously throughout the building. Locating the piping within the building
negates the need of for piping insulation. These systems achieve energy conservation by pumping heat from warm
to cold spaces whenever they coexist anywhere within the building. On demand for heating a space, the conditioner
will absorb heat from the loop circuit, whereas on demand for cooling a space, the conditioner will reject heat to the
loop circuit. The system provides the essential benefit of decentralized and individual choice of heating or cooling.
The occupant may select heating or cooling or shut off the conditioner, serving an individual space without affecting
conditioners operated in other spaces. The occupant may realize this freely at any time of the day or year.
Flexible Investment
The period of the project installing is short and the original cost of investment is low. It is convenient to install
according to occupant demand.
Convenient Control
Each room can be controlled individually without affecting the other space.
High Efficiency
The unit is operated in high efficiency and saves running cost due to water as cooling and heating media.
Running Quiet
The unit is designed into split configuration which is a thorough solution to the noise problem. The indoor unit can be
installed wherever is suitable. The outdoor unit can be placed on outside of the wall or the ceiling, at the balcony or
aisle. It is an ideal device for home, industrial or commercial place due to its low noise.
Elegant, Neat And Tidy
While the rest of the unit is concealed, the wall or ceiling air grilles is exposed. This design concept has in mind: (a)
aesthetic beauty (b) optimum space utilization. It is ideal for office, hotel, hospital and restaurants application.
Easy And Flexible Installation
The physical height of the unit is only 224 mm, and only a clearance of 75 mm between any beam and the false
ceiling is required. It is therefore offering greatest flexibility in selecting installation location.

Microcomputer remote control
The microcomputer remote control has following functions
•Five optional operation modes (heat/cool/dry/fan/auto).
•Fan speed can be set at high, medium, low and automatic.
•Sleep mode automatically increase set temperature since temperature is lower at night thus achieving healthy
sleep.
•Microcomputer controlled thermostat precisely controls room temperature resulting in energy saving and increases
comfort.
•Hot start and hot keep mode do not supply air for 30 sec. After deicing as well as initial operation of heating mode.
This prevents cold draft and maintains the indoor comfort.
•Timer on/off can be preset for the maximum of 15 hours.
Easy maintenance
This simple design concept has a friendly maintenance and servicing in mind. Access to all the internal parts of the
unit can be from either side panels or the top panel of the unit by loosening a few screws.
