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-P2HTE.

• The unit does not operate by pressing the operation switch.
• The above function is available only when the alarm occurs.
• The PCB check using the remote control switch is not available.
• The indication is the data when you are connecting PC-P2HTE. The indication is not the data before the alarm occurs.

9 Control information
bg --
During the transient periods such as starting time and other, the
indicators “
-- ” or “ 00 ” may be displayed for a limited time.
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 “
-- ”.
This indicates the internal information for the remote control switch.
This does not have any specific meaning.
(Ex.) During the operaton of several compressors, the average
temperature of two compressors is indicated.
If the temperature is higher than 126 ºC, “
