Notes (Only for wireless remote controller):
■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 confirm 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 fluorescent 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 inspected.
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.
■To avoid misplacing the remote controller, install the holder included with the remote controller on a wall and be sure to always place the remote controller in the holder after use.
■If the indoor unit beeps 4 times when you are using the wireless remote controller, switch the auto mode setting to the AUTO (single set point) mode or AUTO (dual set point) mode.
For details, refer to the included Notice (A5 sheet) or the Installation Manual.

•Operation modes that are not available to the connected indoor unit models will not appear on the display.
What the blinking mode icon means
The mode icon will blink when other indoor units in the same refrigerant system (connected to the same outdoor unit) are already operated in a different mode. In this case, the rest of the unit in the same group can only be operated in the same mode.
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. According 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 flowing may be heard, they are not malfunction. The reason is that the refrigerant continuously flows 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.

Notes:
●During swing operation, the directional indication on the screen does not change in sync with the directional vanes on the unit.
●Available directions depend on the type of unit connected.
●In the following cases, the actual air direction will differ from the direction indicated on the remote controller display.
1.While the display is in “STAND BY” or “DEFROST” states.
2.Immediately after starting heat mode (while the system is waiting for the mode change to take effect).
3.In heat mode, when room temperature is higher than the temperature setting.
< How to set the fixed up/down air direction >
Notes:
●This function cannot be set depending on the outdoor unit to be connected.
• For SLZ-M·FA series, only the particular outlet can be fixed to certain
direction with the procedures below. Once fixed, only the set outlet is fixed every time air conditioner is turned on. (Other outlets follow UP/
DOWN air direction setting of remote controller.)
■Explanation of word
•“Refrigerant address No.” and “Unit No.” are the numbers given to each air conditioner.
•“Outlet No.” is the number given to each outlet of air conditioner. (Refer to the illustration below.)
•“Up/Down air direction” is the direction (angle) to fix.
