2. COOL MODE : The unit operates according to the difference between the setting and room temperature.
(18°C~30°C)
3. HEAT MODE : The unit operates according to the difference between the setting and room temperature.(16°C~30°C)
*Prevention against cold wind : In order to prevent the cool air from flowing out at the heat mode, the indoor fan does not operate or operates very slowly in the following cases. At this time, the indoor heat exchanger will be preheating.
- For 3~5 minutes after the initial operation
- For deicing operation
- The operation of an indoor fan in accordance with the temperature of an indoor heat exchanger
The temperature of indoor heat exchanger below 28˚C
28˚C~below 34˚C

When this button is pressed again, or when the operating time is 30 minutes, turbo operation mode is canceled and returned to the previous mode.
*But, if you press the TURBO button in DRY or FAN mode that is changed with AUTO mode automatically.
6.
SLEEP MODE : Sleep mode is available only in COOL or
HEAT mode.
The operation will stop after 6 hours.
*In COOL mode : The setting temperature is automatically raised by 1°C each 1hour When the temperature has been raised by total of 2°C, that temperature is maintained.
*In HEAT mode : The setting temperature is automatically dropped by 1°C each 1hour.
When the temperature has been dropped by total of
2°C, that temperature is maintained.
7. FAN SPEED : Manual (3 step), Auto (4 step)
Fan speed automatically varies depending on both the difference between setting and the room temperature.
8.
COMPULSORY OPERATION :

6. Troubleshooting
Since the inverter air conditioner is equipped with Electrical control circuits at both Indoor & outdoor unit, the trouble shooting shall be performed according to the error mode.
Inside the controller of the outdoor unit (inverter), the large capacity of electrolytic condenser so that it takes the time to discharge after the power off since the electrical charge remains(the charging voltage DC 340V).
Take care of the electrical shock by contact on the charging part before the discharge after the power off. (It takes approximately
2 minutes to discharge).
6-1 Basic items for trouble shooting
1. Is the power source proper?
The power source shall be in the range of the rated voltage ±10%. If it is out of this range, it may cause the abnormal operation.
2.
Is the connection made between the indoor and outdoor unit?
The connection between indoor and outdoor unit shall be performed with 4 wire. (connection cable of indoor and outdoor unit + ground wire).
3. The phenomena as follows are not out of order.
No
1
Phenomena
The operation is not done.
Cause and reason
• Is the power off or the power unplugged?
• Does it stop because it is the completion time?
• Unplug and plug again the power source for 2 minutes.
2 The wind comes out but the heating/cooling is not performed.
3 The remote controller does not operate.
4 The wind volume is not adjusted.
5 The temperature is not set.
6 The operation lamp continues to be flickering.
7 The immediate operation starts without control of remote controller when plugged
• Is the filter clogged with dust or dirty?
• Is there any direct light on the outdoor unit or any obstacle against it?
• Is the selected temperature too high?
Lower the selected temperature lower than the current one (during cooling).
• Is the selected temperature too low?
Raise the desired temperature than the current one? (during heating)
• Is the "Fan only Mode" operation?
• Is the battery run out?
• Is the battery inserted in the wrong way(+, -)?
• Is the detection part of the indoor unit blocked?
• Does it interfered with the radio of neon sign?
• Is the operation selected among one of Auto / Dry / Turbo / Sleeping?
• The temperature setting is not required since the wind volume set automatically.
• Check again at the state of Cooling / Fan only / Heating.
• Is the operation selected among the Dry / Turbo / Sleeping / Fan only Mode.
Since the temperature is automatically set, the temperature setting is not required.
• Check again at the cooling / heating state.
• The standard temperature ±2˚C during the automatic operation.
• Push the Operation / Stop button.
• Unplug and plug the power source.
• It is the case that the auto restart function works.
✳
Auto restart function is the convenient function where the operation state is memorized in the Memory IC during the blackout and the operation restarts when the power comes back.

√
Check whether the connection wire of Display board is correctly connected to CN53 connector.
√
Check the voltage of remocon battery. - the voltage of one battery shall be higher than about 1.4V, and then the remocon operates normally.
√
