This may cause a bang, explosion or fire when the unit is used, serviced or disposed of. Lights up while the signal is being transmitted to the indoor unit when the button is pressed. When the backlight is off, pressing any button turns the backlight on and does not perform its function.
When the system is centrally controlled, the button function guide corresponding to the locked button is displayed. When the backlight is off, pressing any button will turn the backlight on and it will stay on for a certain amount of time depending on the screen. Appears when the built-in thermistor on the remote control is activated to monitor the room temperature (a).
This setting is only necessary if the operation of City Multi units is connected to LOSSNAY units. Request cable: You can check the details of the operation data, including the temperature of each thermistor and the error history. Self-Check The fault history of each unit can be checked via the remote control. password To change the maintenance password, do the following.
When the remote control is not working properly, use the remote control control function to troubleshoot the problem.

TROUBLESHOOTING9
Current and past error codes are recorded and displayed on the wired remote control or the control board of the outdoor unit. If an air conditioner error occurs, the indoor unit sensor emits an intermittent beep, the operation light flashes, and the error code is displayed.
Procedure]
For about 2 minutes after it is turned on, the operation of the remote controller is not possible due to the system turning on. 1~4 Check pipe

Indoor/outdoor unit communication error (signal reception error) 1 Abnormal if indoor control board. 6 minutes after power on, it cannot receive any signal normally. Abnormal when data cannot be read normally from the persistent memory of the internal controller board. board 1 Replace the internal controller board. Remote control panel 1 Abnormal if the data cannot be read even-. directly from the persistent memory of the remote control panel.
1 Defective remote control 1 Replace the remote control. due to abnormal water leakage) 1 The unit has abnormal water leakage when the following conditions, a) and b) are met while performing the above-mentioned detection. a).

Note: Refer to the manual of outdoor unit for the details of remote controller. ance failure 1. 3 Normal operation (Each connector on the vane motor side is disconnected or set the fixed vanes by wired remote control.). 2) LED2 on indoor controller board. 2 Refrigerant address for outdoor unit is incorrect or not set. Under cluster control system, there are some units whose refrigerant address is 0.
1 Check the connection of the remote control wires in the case of double triple indoor unit system. When the same problem occurs even if the indoor controller board is replaced, replace the wireless remote control board.
9-5. EMERGENCY OPERATION
9-6. HOW TO CHECK THE PARTS
Do not pull out the connector (CNMF) for the motor while the power is on. This causes problems with the indoor controller circuit board and the fan motor.) Self-check. Check power supply (Remove the connector (CNMF)) Measure the voltage on the indoor controller PCB.

9-8. FUNCTIONS OF DIP SWITCH AND JUMPER WIRE
Each function is controlled by the dip switch and the jumper wire on control P.C. board
10 SPECIAL FUNCTION
- Take the cover off the electric box of the decorative panel. (2 screws) 2) Set up the dip switches of SW22 or SW2 on the control board of the
- Put the cover back on the electric box of the decorative panel
- Press the "Down" button to lower the air intake grille
- Remove the filter or air intake grille and clean them
- Attach the filter and air intake grille
- Press the "Up" button on the remote controller to put the air intake grille in place
- Ensure that the air-conditioner is not running
- Remove the filter and/or air intake grille to clean them
How to operate the up/down function using the wireless remote control 1) Make sure the air conditioner is not running. By default, the air intake louver will automatically stop at a landing distance of 1.6 m from ceiling level. If the air intake grille is not placed in the correct position at the same time, the operation is automatically retried.
Wireless remote control for automatic filter lift panel Make sure the air conditioner is not running. How to operate the up/down function using the wired remote control (PAR-30MAA / PAR-31MAA). Raise or lower all air intake louvers managed by the remote control at the same time.
If you press the button ( ) while the air intake grill is moving down, the air intake grill may stop lowering, but it will not stop immediately. As standard, the air intake grill stops automatically at the lowering distance of 1.6 m from the ceiling level. If you press the button ( ) while the intake grill is moving up, the air intake grill may stop rising, but it will not stop immediately.
After a while, the air intake grille will begin to rise and then return to its place. .. buttons simultaneously for 2 seconds or more. If you press the "FILTER" button, when "Unit No." or "Refrigerant address no." flashes, after a while the up/down air flow direction of the displayed air conditioner will be switched down; and the air flow will be up/down the air flow direction of the displayed air conditioner will be changed downwards; and the airflow direction of the other valves will all be blocked. In step 5) described below, identify the target air conditioner by changing the "Unit No." and.
Up/down operation with individually specified conditioner (when used in combination with Mr. SLIM model). Raise or lower the air intake grille of the specific air conditioner you choose from among all those managed by that remote control. The air intake louver does not move in the no-load detection or obstacle detection state.
2) Special operation
When using the wired remote control, there will be a slight delay in stopping due to transmission speed.

10-4. TROUBLESHOOTING
When you restart the unit to work after power off or OFF operation, the unit that was working will start working. and set the request code no. which is not the same as the current one and set the previous request code no. 2) Level 2 power-on function Function overview. When the 1st unit is NOT able to provide sufficient capacity for extremely high demands and the actual room temperature reaches the set point *, the 2nd unit starts working in conjunction with the 1st unit. When the actual room temperature drops to 4 degrees C below the set point *, the 2nd unit automatically stops working.
ROTATION FUNCTION (AND BACK-UP FUNCTION, 2ND STAGE INCLUSIVE FUNCTION). 1) Rotation function (and Back-up function). This function is only available by the grouping control system (INDOOR UNIT: OUTDOOR UNIT=1:1) of 2 refrigerant groups. Indoor main unit must be connected to the wired remote control, and the transmission line (TB5) for main and sub unit must also be connected. This function cannot be set by the wireless remote control.).
How to set the rotation function (Backup function, Level 2 power on function) You can set these functions with the wired remote control.
