Caution:
Obtain an approval from the client for the following precautions as necessary.
1. The communication between AE-200/AE-50/EW-50 and the air conditioning units will stop while
the software is being updated. Although the unit in operation may detect a communication error
and an error sign may appear on the local remote controllers, the unit will continue its operation
and be operable from the local remote controllers.
* Note that Mr. Slim indoor units or systems with no local remote controllers may detect a communication error and come
to an abnormal stop.
2. Record the operation status of the air conditioning units immediately before updating the
software. After the software update completes, check the operation status of the units, and
manually operate the units as necessary.
3. Some operations and functions, such as scheduled operations, billing function, Peak Cut control,
energy management function, will be disabled while the software is being updated. Check the
setting details of these functions beforehand, and update the software when it does not affect
these functions.
4. If the functions in the table below are used on the TG-2000A, avoid updating the software during
the time period indicated in the right column.
