4) Deletion of information on address not existing
• Deletion of information on address not existing ................................................... 5
This operation is to be conducted when "6607" error (No ACK error) is displayed on the remote controller due to the
setting error during test run, or due to the old memory remaining at the time of the modification of group composition,
and the address with no corresponding units will be deleted.
Note: The connection information (connection between indoor unit and outdoor unit) on the refrigerant system
cannot be deleted.
An example for deleting the system controller "250" from the indoor unit "007" is shown below.
[Operation procedure]
1 With the remote controller under stopping mode or with "HO" displayed on the LED, press and hold the
buttons (A + B) simultaneously for 2 seconds to switch to the registration mode.
2 Use button (G) to switch to the interlocked setting mode (ii). (See the figure below.)
3 Call up the address of existing unit on "OA Unit Address No." using the
button (E) to display the address to be deleted. (See the figure below.) As the error display on the remote controller is
usually transmitted from the indoor unit, "OA UNIT ADDRESS No." is used as the address of the indoor unit.
4 Press the
CLOCK → ON → OFF
