Although the wireless controller is used for the wall type indoor unit with the built-in receiver part, you can check the alarm
code by connecting the PC-ART.
N O T E
• The unit does not operate by pressing the operation
switch.
• The above function is available only when the alarm oc-
curs.
• The PCB check by means of the remote control switch is
not available.
• The indication is the data when you are connecting
PC.ART.
The indication is not the data before the alarm occurs.
Contents of the Check mode 1
The next indication is shown if you press the part “▲of the TEMP switch.
If you press the part “▼ of the TEMP switch, the previous indication is shown.

Indication of the category code
Indication of the temperature, etc
(Ex.) During the operaton of several compressors, the average
temperature of two compressors is indicated.
If the temperature is higher than 126 ºC, “
”
This indicates the internal information for the remote control switch
This is indicated only when a remote sensor is connected.
The indicator "--" is normally displayed.
RPK series cannot connect a remote sensor.
Therefore, the indicator is "--".
During the transient periods such as starting time and other, the
indicators "" or "" may be displayed for a limited time.
