Operating Instructions
5Samsung Electronics
1. AUTO MODE : In this mode, operation mode(COOL,
HEAT) is selected automatically by the difference
between the setting and room temperature.
√√In case of Heat pump model.
√√Cooling or heating operation is selected based on
difference of Ts and Tr. Cooling and heating operation
is automatically interchanged during an operation.
√√In case of Cooling only model.
Ts : Setting temperature.
2. COOL MODE : The unit operates according to the
difference between the setting and room temperature.
(16°C~30°C)
3. HEAT MODE(In case of Heat pump model) :
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
*High temperature release function : It is a function to
detect an outdoor overload by the sensor of an indoor
heat exchanger and to turn the outdoor fan or the
compressor ON/OFF for safety.
*Deice : Deicing operation is controlled by indoor unit's
heat exchanger temperature and accumulating time of
compressor's operation.
Deice ends by sensing of the processing time by deice
condition.
4. DRY MODE : Has 4 states, each determined by room
temperature.
The unit operates in DRY mode.
*Compressor ON/OFF time is controlled compulsorily
(can not set up the fan speed, always breeze).
*Protective function : Low temperature release.
(Prevention against freeze)
5. TURBO MODE : This mode is available in AUTO, COOL,
HEAT, DRY, FAN MODE.
When this button is pressed at first, the air conditioner is
operated "powerful" state for 30 minutes regardless of the
setting temperature, room temperature.
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 automatical-
ly 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 :
For operating the air conditioner without the remote
control.
*The operating is the same function that AUTO MODE in
the remote control.

6. Troubleshooting
6-1 Basic items for trouble shooting
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).
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.
PhenomenaNo

The operation is not done.
The wind comes out but the
heating/cooling is not performed.
The remote control does not
operate.
The wind volume is not adjusted.
The temperature is not set.
The operation lamp continues to be
flickering.
The immediate operation starts
without control of remote control
when plugged
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.
• 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.
