When using the wireless remote controller, point it towards the receiver on the indoor unit.

■

If the remote controller is operated within approximately 2 minutes after power is supplied to the

indoor unit, the indoor unit may beep twice as the unit is performing the initial automatic check.

■

The indoor unit beeps to conﬁ rm that the signal transmitted from the remote controller has been

received. Signals can be received up to approximately 7 meters in a direct line from the indoor unit in an area 45° to the left and right of the unit. However, illumination such as ﬂ uorescent lights and strong light can affect the ability of the indoor unit to receive signals.

■

If the operation lamp near the receiver on the indoor unit is blinking, the unit needs to be in-

spected. Consult your dealer for service.

■

Handle the remote controller carefully! Do not drop the remote controller or subject it to strong

shocks. In addition, do not get the remote controller wet or leave it in a location with high humidity.

Information for multi system air conditioner (Outdoor unit: MXZ series)

► Multi system air conditioner (Outdoor unit: MXZ series) can connect two or more indoor units with one outdoor unit. Accord ing to the capacity, 2 or more units can operate simultaneously.

• When you try to operate 2 or more indoor units with 1 outdoor unit simultaneously, one for the cooling and the other for heating, the operation mode of the indoor unit that operates earlier is selected. The other indoor units that will start the operation later cannot operate, indicating an operation state in blinking. In this case, please set all the indoor units to the same operation mode.

• There might be a case that the indoor unit, which is operating in (AUTO) mode. Cannot change over to the operating mode (COOL HEAT) and becomes a state of standby.

• When indoor unit starts the operation while the defrosting of outdoor unit is being done, it takes a few minutes (max. about 15 minutes) to blow out the warm air.

• In the heating operation, though indoor unit that does not operate may get warm or the sound of refrigerant ﬂ owing may be heard, they are not malfunction. The reason is that the refrigerant continuously ﬂ ows into it.

Automatic operation

■

According to a set temperature, cooling operation starts if the room

temperature is too hot and heating operation starts if the room temperature is too cold.

■

During automatic operation, if the room temperature changes and

remains 2 °C or more above the set temperature for 15 minutes, the air conditioner switches to cooling mode. In the same way, if the room temperature remains 2 °C or more below the set temperature for 15 minutes, the air conditioner switches to heating mode.

Cooling mode 15 minutes (switches

from heating to cooling)

5.3. Temperature setting

► To decrease the room temperature:

Press button 3 to set the desired temperature. The selected temperature is displayed 3.

► To increase the room temperature:

Press button 3 to set the desired temperature. The selected temperature is displayed 3.

• Available temperature ranges are as follows: Cooling/Drying: 19 - 30 °C Heating: 17 - 28 °C Automatic: 19 - 28 °C

• The display blinks either 8 °C - 39 °C to inform you if the room temperature is lower or higher than the displayed temperature.

(This display does not appear on the wireless remote controller.)

5.4. Fan speed setting

■

Press the Fan Speed button 5 as many times as necessary while the

system is running.

• Each press changes the force. The currently selected speed is

shown at 5.

Note:

●

The number of available fan speeds depends on the type of unit connected.

● In the following cases, the actual fan speed generated by the unit will differ

from the speed shown the remote controller display.

1. While the display is showing “STAND BY” or “DEFROST”.

2. When the temperature of the heat exchanger is low in the heating mode.

(e.g. immediately after heating operation starts)

3. In HEAT mode, when room temperature is higher than the temperature

setting.

4. When the unit is in DRY mode.

Because the room temperature is automatically adjusted in order to

maintain a ﬁ xed effective temperature, cooling operation is performed a few degrees warmer and heating operation is performed a few degrees cooler than the set room temperature once the temperature is reached (automatic energy-saving operation).
