This document serves as the Technical Manual for the IEWH/ICHH Series High Wall Inverter air conditioner, operating at 220-240V/1/50Hz. It provides comprehensive information regarding the device's functions, usage, and maintenance, emphasizing safety precautions throughout.
Function Description
The IEWH/ICHH Series High Wall Inverter is a split-type air conditioning unit designed to provide comfortable airflow and prolong its service life through various protective functions. It operates in multiple modes including cooling, heating, dry, and fan-only, with an inverter technology for efficient performance.
Key protective functions include:
- Delay-starting protection for the compressor: To maintain pressure balance in the cooling system, the compressor restarts at least 3 minutes (5 minutes in heating mode) after being turned off. There's an initial 1-minute delay for the compressor to start after the unit is first electrified.
- Freeze-prevention: During cooling and dehumidification operations, the compressor or outdoor fan may stop, and the indoor fan speed will automatically increase to prevent the indoor heat exchanger from freezing.
- Dry for enzyme-prevention (optional): In cooling mode, the indoor fan motor continues to run at a low speed for 3 minutes after the unit is turned off to maintain a dry internal condition, preventing enzyme growth.
- Reset power or Auto restart (alternative):
- Reset power: In the event of a power suspension, the air conditioner automatically switches off. When power is restored, the unit automatically resets. For energy saving, if no one is in the room, the air conditioner enters PAUSE status, requiring the user to turn it on via the remote controller.
- Auto restart: The unit stores the last operating mode, airflow settings, and temperature settings. If a power failure occurs during operation, the unit will automatically resume the same operating conditions once power is restored.
- Cooling overload working (optional): If the outdoor heat exchanger temperature becomes too high during cooling operation, the indoor fan speed automatically adjusts to a lower gear, and the compressor may stop.
- Drip proof (optional): During cooling and dehumidification, the louver blades automatically adjust their position to prevent water dripping.
Usage Features
The air conditioner is controlled via a remote controller, which offers a range of settings and display options.
- Display Screen: Shows current settings such as temperature, operating mode (AUTO, HEAT, COOL, DRY, SWEEP), fan speed (Auto, High, Medium, Low), and various indicators (RUN, TIMER, Compressor, Temperature). Flashing indicators signify abnormal operation, requiring contact with the distributor.
