Auto Operation of Auxiliary Heater, Auxiliary Heater Enabled, Auxiliary Heater Disabled, and Auxiliary Heater Used Independently. 20 Aux heater can only enabled in Heat mode CAUTION Auto Operation of Auxiliary Heater: Upon power on, the air conditioner will determine whether to start the auxiliary heater automatically based on the ambient temperature in heating mode. At this moment, the air conditioner operates in "Auto Operation of Auxiliary Heater" mode. Auxiliary Heater Used Independently: The auxiliary heater can be used independently without starting the compressor. It only applies to certain customized models. The auxiliary heater can only be started in heating mode. The auxiliary heater is an additional heating component to the air conditioner, but the power consumption will increase after the auxiliary heater starts working. Powerful operation: After powerful operation is enabled, the IDU will accelerate cooling/heating. Powerful operation is only available for cooling or heating mode. After powerful operation is enabled, the maximum runtime of the IDU is 30 minutes. After powerful operation is disabled, the IDU will be controlled normally. Power operation will quit in case the operating mode or fan speed is changed. 21 Wind sensing of smart panel : The wired controller can set the IDU air flow to "Comfortable" or "Off". If the air flow is set to

"Comfortable", the fan speed and swing angle of the IDU will automatically adjust to a relatively comfortable level.

Under group control, the device sends commands to all IDUs in a unified manner.

(1) One to more group control Enable the one to more function by entering the Engineering Settings > IDU Settings > SiteConfig. Once this function is enabled, the system enters the one to more group control by default. Under group control, the device sends commands to all IDUs and all IDUs execute the same commands. The main interface of the device under one to more group control is the same as that under one to one control. The function in the list should be subjected to the IDU. 41 5.16 Fault Prompt Fault List C51/E9 communication fault between wired controller and IDU Press "Information" to view error codes on the homepage when fault occurs. Error display 1. In case any IDU or ODU fails, the wired controller displays the fault code. In case a communication fault occurs between the wired controller and any of the IDUs, the wired controller reports "C51". 2. The wired controller can record up to 10 faults, each of which includes the address of the faulty device, the fault code, and the time when the fault occurs. 42 Error code:C51 6 FAQ The air conditioner is not working, but prompts that neither cooling nor heating option can be set. What should I do?

The set mode is inconsistent with the operating mode of ODU. Please change the set mode to cooling/heating. The word "Filter" is displayed on the operation panel. What should I do?

Please contact the after-sales service to clean or replace the filter/heat exchanger. Please contact your local dealer What should I do if the air conditioner is not running as strongly as it should be? What are the possible causes?

Please check in the following sequence:

1. Whether the set mode is cooling or heating;

2. Whether the louvers of the air outlet face down;

3. Whether there is any barrier 20 cm around the IDU and whether the IDU is clogged and needs to be cleaned. 4. If the problem persists, Please contact your local dealer. How can I adjust the temperature on my air conditioner? What is the ideal room temperature for human comfort?

The set temperature on air conditioner should be different from the room temperature. The most comfortable temperature for summer is between 24C and 26C, and that for winter is between 18C and 20C. You may set the temperature depend on actual situations. 43 Why does the air outlet of my air conditioner drip?

The room is filled with a great amount of moisture. Please close the doors and windows. Why does the ODU of my air conditioner drip?

1. During cooling in summer, condensation water generated by the unit is discharged to the outside through the IDU drainage pipe. If the drainage pipe is close to the ODU, the condensation water may be mistaken for the water leaked from the ODU. The ODU does not drain any water during cooling. 2. During heating in winter, the ODU may be frosted. Then, the unit will defrost and the defrosted water will flow from the drainage outlet at the bottom of the ODU. This is a normal phenomenon instead of a fault of the air conditioner. To deal with this, you may contact the after-sales personnel or the installer to install an ODU drainage pipe. How should I use a wired controller? Please provide simple operation instructions. Please scan the QR code on the user manual for the operation instructions. Why does air conditioner fail to start after it is powered on?

In winter, it takes some time for your air conditioner to warm up. Please wait a few minutes. 44 Why does air conditioner keep operating after it is powered off?

After your air conditioner is powered off, there is some residual moisture inside the conditioner. It operates for a while to eliminate the moisture, so as to reduce the possibility of mould growth. Why are the air conditioner functions non-adjustable?

If the display panel presents a centralized controller icon, the air conditioner is locked. In this case, please contact the air conditioner system administrator. 45 7 INSTALLATION 7.1 Installation Precautions To ensure correct installation, read the "Installation" section of this manual. The content provided here covers warnings, which contain important information about safety that must be followed. CAUTION Entrust a local distributor or local service agent to appoint a qualified technician to perform the installation. Do not try to install the unit by yourself. Do not knock, throw, or randomly disassemble the wired controller. The wiring must be compatible with the wired controller current. Use the specified cables, and do not place any heavy object on the wiring terminals. The wired controller line is a low-voltage circuit, which cannot come into direct contact with the high voltage line or be laid in the same wiring tube together with the high voltage line. The minimum spacing of wiring tubes is 300 to 500 mm. Do not install the wired controller in corrosive, flammable and explosive environments or places with oil mist (such as a kitchen). 46 Do not install the wired controller in a wet place and avoid direct sunlight. Do not install the wired controller when it is powered on. Please install the wired controller after painting the wall;

otherwise, water, lime and sand may enter the wired controller. 7.2 Installation Method 7.2.1 Wiring requirements One-to-more and two-to-more IDU 1#
