- 6608Error codeNo response When no response command is returned although acknowledgement (ACK) is received after transmission, an error is detected. When the data is transmitted 10 times in a row with 3 seconds interval, an error is detected on the transmission side. Note:The address/attribute appeared on the display on the remote controller indicates the controller where an error occurred. | No response When no response command is returned although acknowledgement (ACK) is received after transmission, an error is detected.When the data is transmitted 10 times in a row with 3 seconds interval, an error is detected on the transmission side. Note: The address/attribute appeared on the display on the remote controller indicates the controller where an error occurred.
- 6831Error codeMA controller signal reception error (No signal reception): Communication between the MA remote controller and the indoor unit is not done properly. No proper data has been received for 3 minutes.
- 6832Error codeMA remote controller signal transmission error (Synchronization error): MA remote controller and the indoor unit is not done properly. Failure to detect opening in the transmission path and unable to send signals Indoor unit : 3 minutes Remote controller : 6 seconds
- 6833Error codeMA remote controller signal transmission error (Hardware error): Communication between the MA remote controller and the indoor unit is not done properly. An error occurs when the transmitted data and the received data differ for 30 times in a row.
- 6834Error codeMA controller signal reception error (Start bit detection error): Communication between the MA remote controller and the indoor unit is not done properly. No proper data has been received for 2 minutes.
- 7100Error codeHeat source Total capacity error unit The model total of indoor units in the system (including LOSSNAY with heating and moistening system installed) with one heat source unit exceeds limitations.

- 7107Error codeBranch port setting error Branch port No. setting of unit is wrong. Total type number per each port is greater than the specification. Is there a BC controller (Sub)? NO Is single branching setting made on 4 or more indoor units? NO Is the total type number of the indoor unit, on which single branching setting is made, greater than the item 1)? When multiple branches merge, is the smallest number set on the branch port? Change the branch port No.
