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 transmitted
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).

Address
which

be existed
- - (1) Although the address of ME
remote controller has been
changed after the group is set
using ME remote controller,
the indoor unit is keeping the
memory of the previous address.
The same symptom will
appear for the registration with
SC.
Delete unnecessary information
of non-existing address
which some indoor units have.
Use either of the following two
methods for deletion.
(2) Although the address of
LOSSNAY has been changed
after the interlock registration
of LOSSNAY is made using
ME remote controller, the indoor
unit is keeping the memory
of the previous address.
1) Address deletion by ME remote
controller
Delete unnecessary address information
using the manual setting
function of ME remote
controller. Refer to this service
handbook "IV [2] Group Settings
and Interlock Settings via
the ME Remote Controller 1. (3)
Address deletion".
2) Deletion of connection information
of the outdoor unit by the
deleting switch
Note that this switch deletes
all the group information set
via ME remote controller and
all the interlock information
of LOSSNAY and the indoor
unit.
