Usage Features
Precautions for Safety:
- Installation: Installation should be performed by a qualified professional. The remote controller should not be installed in direct sunlight, near heat sources, or where signals cannot reach the indoor unit. Fluorescent lamps with rapid start or inverter systems, or equipment emitting infrared rays, may interfere with signal reception.
- Operation: Prevent liquids from spilling on the remote controller. In case of abnormal operation (e.g., burning smells), immediately turn off the main power supply and contact the dealer.
- Reinstallation/Repair: Do not attempt to repair the unit yourself; contact the dealer for service.
Changing Batteries:
- To load batteries, remove the battery cover and insert two new R03 or LR03 (AAA) batteries, observing the correct polarity (+/-).
- To remove batteries, remove the cover and lightly slap the batteries out onto your palm.
- Replace batteries if there is no receiving beep from the indoor unit or if the air conditioner cannot be operated. Remove batteries if the remote controller will not be used for more than one month to prevent leakage.
Adjusting Clock:
- After inserting batteries, the clock panel will flash AM 0:00.
- Press the CLOCK button (using a pencil tip) to make the display flash.
- Use the TIMER ▲ or ▼ buttons to set the current time. Each push changes the time by one minute; continuous pushing changes it by ten minutes.
- Press the SET button to confirm the time and start the clock.

- Display Lamp: Indicates unit status and errors.
- Lamp (Green): Illuminates when the unit is on.
- Lamp (Green): Illuminates when the timer is reserved.
- Lamp (Orange): Illuminates during heating operation (start, temp. controller active, defrost) and flashes during trouble.
- If "pi, pi" sounds and lamps flash alternately, the desired mode operation is not performed due to disagreement in operation mode.
Automatic Operation (Auto Changeover):
- Select "A" mode using the Mode Select button. The unit will automatically select the operating mode (Cooling/Heating) based on room temperature.
- This mode is not available for SMMS series units other than Super Heat Recovery Multi types, or for Cooling only models.
Adjusting Louver Direction:
- To Set Louver Direction: Push the FIX button during operation. Each push changes the direction.
- For heating, direct louvers downward for hot air to reach the floor.
- For cooling/dry, direct louvers upward to prevent condensation and dripping.
- To Start Swinging: Push the SWING button. Louvers will automatically move up and down.
- To Stop Swinging: Push the SWING button again when the louver is at the desired position.
- Caution: Do not push FIX during swing operation. Stop swinging first. Avoid prolonged downward airflow during cooling/dry to prevent condensation.
Mounting Remote Controller Holder:
- To fix the holder to a wall, first check signal reception by pushing START/STOP at the desired location.
