Series' brief Introduction

1. Comfortable: wide-angle airflow
The vertical dual-flap and horizontal wide-angle louvers ensure the cool/warm air
reaching every corner of the room.

2. Health air purifying and negative ion function

An air purifying filter with deodorizing and disinfecting function keeps the air clean
and users healthy. The negative ion generator can produce the negative ion that
make the air fresher and cleaner.

3. Quiet operation

Fan with Random-pitched Blades.
Random-pitched blades help to reduce operating noise while maintaining a high
airflow rate.

4. Energy efficient

The design of inner-grooved copper tube greatly increases the refrigerant contact
area and the efficiency of cooling/heating functions.

5. Convenience

Washable panel and Auto-restart function:

- The grille can be removed easily and washed when necessary.

- All series have auto-restart function after a power failure. At the end of a blackout,
all Units automatically restart with the previous settings.

6. Wide variety of functions
24-Hour Timer:

24-Hour Timer allows Users to select the exact time they would like the air conditioner
to turn on and turn off.

7. Night-set models
When the air conditioner is operating on the timer-off circuit. The preset room
temperature gradually rises (going down in Heating) before the Unit's stop. Users can
sleep comfortably without sudden change in temperature.

8. "Dry" Program
This function automatically reduces the level of humidity while maintaining the preset

indoor temperature.

2. Operation modes.

1. Full-automatic approach.(

After the air conditonic is switched on, when the system is at the automa tic option, the
appropriate operation mode will be chosen according to the difference between the set temperature
and the indoor temperature . In the following option conditions, Tr stands fo r indoor temperature
and Ts stands for set temperature.

The system will choose the operation mode according to the following conditions when entering
into the automatic operation option for the first time.

Tr≥Ts-3℃ Choose the cooling mode

Tr＜Ts-3℃ Choose the warming mode

Under the automatic option, the system will switch between the cooling and warming modes
according to the change of the indoor temperature. If the air conditionic is under the cooling mode,
when the set temperature for stopping th e compressor is reached, the compre ssor will be stopped.
The indoor temperature will be tested aga in 15 minut es after the s top of the co mpressor . At the
moment, if the tested temperat ure is un der the Tr＜Ts-3℃ condition, the system will be switched into the

warming mode. If not, the system will remain in the cooling mode. If the air conditionic is under the warming mode,

when the set temperature for stopping th e compressor is reached, the compre ssor will be stopped.
The indoor temperature will be tested aga in 15 minut es after the s top of the co mpressor . At the
moment, if the tested temper ature is under the Tr（compensation value not included）≥Ts+3℃ condition,

the system will be switched into the cooling mode. If not, the system will remain in the warming mode. If the system
is stopped by a change on the set temperature, the decision of mode switching will be made 3 minutes later.

When the system is switched to the automatic option from other opti ons, if the operation
conditions changes ( new decision should be made before new operation), the system will be stopped
for 3 minutes and then enter the relative mode according to the inlet air temperat ure.

This mode has the timing fu nction an d dorman t function. Under the cooling m ode, the c ooling
dormant function is stimulated while the dormant heating function takes effects under the heating
mode.

This mode has the strength/ mute function. Under the cooling mode, the cooling st rength function i s
stimulated while the strength heating function takes effects under the heating mode.

The airflow speed control can choose the low, medium, high or automatic option and send the
airspeed signal to the outdoor system.

Automatic lowered airflow direction board. (the same with the cooling or he ating mode.)

2． Cooling operation mode
* Temperature control range: 16℃---30℃
* Temperature difference: ±1℃

* Control features: When Tr（inpu t airflow）>Ts（set temperature）℃, the compressor will be
opened,the indoor fan will operate at the set speed and the mode signal will be sent to the outdoor
system. When Tr（input airflow）< Ts（set temperature）℃, the compressor will be opened,the indoor
fan will operate at the set speed and the mode signal will be sent to the outdoor system. The system
will keep the original status if Tr= Ts.

* Airflow speed control: (temperature difference 1℃)

Automatic: When Tr>=Ts+3℃, hi gh speed.
When Ts+1℃=<Tr<Ts+3℃, medium speed
When Tr<Ts+1℃, low speed
When the sensor is off, low speed

When the airflow speed has no delay from the high to low switching, the speed should be delayed
for 3 minutes (remain at high speed for 3 minutes.) before the next switch.

Manul: When the system is operating, you can set the high, medium or low speed manually. ( When

the sensor is on or off, the system will chan ge the speed 2 seconds after rec eiving the signal.)

*Airgate location control: the loca tion for the airga te can be set accordin g to your needs.
*Defrosting function: preventing the frosting on the indoor heat exchanger (when cooling or

demoisture). When the compress or works continu ously for 5 minute s (adaptable in EE PROM) and the
