7. Notes Regarding Use

Please read this information carefully before attempting a test run.
The following control information should be thoroughly explained and provided to the users of this device. (Please provide these
instructions to the user once the installation is complete.)
* This M-NET Interface operates RACs using the controls of a packaged air conditioner (city-multi), but there are several limita-
tions imposed as a result of the functional differences between RACs and packaged air conditioners.
1. When operating the system using a system controller or ME Remote Controller, these operations will not appear on the
display of the wireless remote controller.
2. The dehumidifying modes of individual RACs cannot be operated using the ME Remote Controller/System Controller.
When an independent dehumidifying mode is set using the remote controller that came with the RAC, "Dry" will appear on
the display because there is no corresponding mode on the ME Remote Controller/System Controller.
3. Functions that are available on the ME Remote Controller/System Controller but that are not available on the RAC can be
operated by switching to a predetermined separate operation mode. (See the "Table of RAC Functions Activated from the
ME Remote Controller/System Controller.")
4. Functions that are available on the remote controller of the RAC but are not available on the ME Remote Controller/System
Controller will produce a predetermined display. In this case, the actual operation and the display may differ. (If the fan
speed is automatically set using the remote controller that came with the RAC, the setting "High" will appear on the ME
Remote Controller/System Controller. Likewise, if the fan direction is set to automatic, the setting "Downward Air Flow 80%"
will appear on the ME Remote Controller/System Controller.)
5. Because the temperature range of the RAC is broader than the ME Remote Controller/System Controller, when the RAC is
set to lower than 17°C or higher than 30°C, the temperature display on the ME Remote Controller/System Controller will
show the minimum or maximum temperature that can be set. (For example, even if the room air conditioner is set to cool a
room to 16°C, the display on the ME Remote Controller/System Controller may read "17°C.")
The RAC operates according to the room temperature detected by the RAC unit.
6. Timer operations should be set using only the remote controller that came with the RAC or the ME Remote Controller/
System Controller. If both are used to set the timer to the same time, the timer will not function properly.
7. When the timer is set using the remote controller that came with the RAC, the timer information will not be displayed on the
ME Remote Controller/System Controller.
8. If the timer is set using the ME Remote Controller/System Controller, the timer set using that device will not be cancelled
even if the unit is turned off using the remote controller that came with the RAC.
9. When manual operations using the system controller are prohibited, the remote controller that came with the RAC will not
function, but the beeping sound that is emitted when it is operating normally will still sound.
10. To clear an error message from the display of the ME Remote Controller/System Controller, briefly turn off the unit using
the ME Remote Controller/System Controller or the remote controller that came with the RAC. (The error display on the air
conditioner unit may be cleared automatically, but it will not clear from the ME Remote Controller/System Controller until
the unit is turned off.)
11. The room temperature sensor installed in the ME Remote Controller cannot be used.
