7.1.15 Abnormality confirmation approaches
1. indoor temperature sensor abnormality:
Under the operation, the normal temperature ranges from 120 degree to -30 degree. When the temperature
goes beyond this range, the abnormality can be confirmed. If the temperature goes back into the range, the
system will automatically resume.
2 .indoor heat interaction sensor abnormality:
Under the operation, the normal temperature ranges from 120 degree to -30 degree. When the temperature
goes beyond this range, the abnormality can be confirmed. If the temperature goes back into the range, the
system will automatically resume.
3 .indoor malfunction:
Out door malfunction: When the indoor system receives the outdoor malfunction codes, it will store the code
into E2 for the malfunction list resume. The indoor system will continue to operate according to the original
status, the malfunction code will not be revealed or processed.
4. transmission abnormality:
If the indoor system can’t receive the outdoor system for 8 minutes, the communication abnormality can be
confirmed and reported and the outdoor system will be stopped.

8.1System configuration
After the installation and test operation of the room air conditioner have been completed, it should be
operated and handled as described below. Every user would like to know the correct method of operation
of the room air conditioner, to check if it is capable of cooling(or heating) well, and to know a clever method
of using it. In order to meet this expectation of the users, giving sufficient explanations taking enough time
can be said to reduce about 80% of the requests for servicing. However good the installation work is and
however good the functions are, the customer may blame either the room air conditioner or its installation
work because of improper handling. The installation work and handing over of the unit can only be
considered to have been completed when its handling has been explained to the user without using
technical terms but giving full knowledge of the equipment.
