[7-8 Error Code Definitions and Solutions: Codes [6000 - 6999] ]
7-8-15
Error Code [6607] No Error Source Address
1. Error code definition
No ACK error
2. Error definition and error detection method
The error is detected when no acknowledgement (ACK signal) is received after the transmission. (eg. When the data is trans-
mitted six times in a row with 30 seconds interval, the error is detected on the transmission side.)
The address/attribute appeared on the display on the remote controller indicates the controller which did not provide
the response (ACK).
3. Cause, check method and remedy
(1)
Although the address of ME remote controller has been
changed after the group is set using ME remote control-
ler, the indoor unit is keeping the memory of the previous
address. The same symptom will appear for the registra-
tion with SC.
(2)
Although the address of LOSSNAY has been changed af-
ter the interlock registration of LOSSNAY is made using
ME remote controller, the indoor unit is keeping the mem-
ory of the previous address.

Cause
- 233 -
Check method and remedy
Delete unnecessary information of non-existing
address which some indoor units have.
Use either of the following two methods for dele-
tion.
1)
Address deletion by ME remote controller
Delete unnecessary address information using the
manual setting function of ME remote controller.
For details, refer to the following page(s). [6-3-4
Address Deletion](page 154)
2)
Deletion of connection information of the outdoor
unit by the deleting switch
Note that the above method will delete all the
group settings set via the ME remote controller and
all the interlock settings between LOSSNAY units
and indoor units.
Procedures
1)
Turn off the power source of the outdoor unit,
and wait for 5 minutes.
2)
Turn on the dip switch (SW5-2) on the outdoor
unit control board.
3)
Turn on the power source of the outdoor unit,
and wait for 5 minutes.
4)
Turn off the power source of the outdoor unit,
and wait for 5 minutes.
5)
Turn off the dip switch (SW5-2) on the outdoor
unit control board.
6)
Turn on the power source of the outdoor unit.

Do you have a question about the PURY-HP72 and is the answer not in the manual?
Questions and answers
what is the set up mode for recovery, and charging of sys?
Why can control my indoor unit with centralize control
You may not be able to control your Mitsubishi Electric PURY-HP72 indoor unit with centralized control for the following reasons:
1. The power jumper connector on the outdoor unit may not be correctly set. It should be connected to CN40 on only one outdoor unit.
2. The central control switch (SW5-1) on the control board of all outdoor units must be set to "ON."
3. Address settings may not be correctly configured. The main indoor unit should be assigned the smallest address (e.g., IC00), and correct port number settings are required.
4. If using a remote controller alone, an interlock setting from the remote controller is needed.
5. Both ME and MA remote controllers cannot be connected to the same indoor unit group.
6. System controller power issues may occur if the outdoor unit fan rotates due to external forces, causing the system controller to detect an error.
7. Improper wiring or incorrect voltage at TB7 may also prevent operation.
Check each of these conditions to ensure proper centralized control.

Why can’t control indoor unit with centralize control and stay the MA control set up can’t. Control the mode
The Mitsubishi Electric PURY-HP72 indoor unit cannot be controlled with centralized control and the mode control setup does not function due to the following reasons:
1. Central control is not possible if the indoor/outdoor transmission line is used, even if TB7 terminals are daisy-chained.
2. Shielded cables must be used, and the connection must only be made after confirming the voltage is below 20 VDC.
3. Improper connection of the transmission line for centralized control, such as not correctly daisy-chaining terminals M1 and M2 or not short-circuiting the earth and S terminals on TB7.
4. If a power supply unit is not connected to the centralized control line, the power jumper connector must be moved from CN41 to CN40 on one outdoor unit—if this is not done, mode control will not function.
5. Overlapped indoor unit addresses or noise interference on the remote controller lines can also prevent proper control.
6. Failure to set one MA remote controller to MAIN or exceeding its capacity can result in control failure.
All these factors must be correctly configured for centralized and mode control to function properly.
