Procedure 3: writing setting data in EEPROM
(The EEPROM of the service P.C. board has been set to the factory default values.)
1
Push the
+
+
buttons simultaneously and
hold for at least 4 seconds. (This number corresponds
to the same number shown on the Remote Controller
Operation Diagram.)
(Under UNIT No., ALL is displayed.)
At the same time, the CODE No. (DN code) 10 is displayed,
and the fan of the indoor unit comes on, with the louver
swinging, depending on the model.
2
Push the left part of the
button to display the
indoor unit No. one by one in the group control. Specify
the indoor unit No. whose service PC board was
replaced.
(This operation is not available if the UNIT No. shows
.)
3
The
button allows you to moved the CODE No. (DN code) up / down by one place.
4
First, set the type and capacity codes of the indoor unit.
(Changing the type and capacity codes in EEPROM overwrites the factory default settings.)
(1) Set the CODE No. (DN code) to 10 (no change)
(2) Use the
button to select the type.
(For example, 0001 is for the 4-way cassette type.) - See the CODE No. list.
(3) Push the
button. (The display should change from flashing to steady.)
(4) Use the
button to set the CODE No. (DN code) to 11.
(5) Use the
button to set the capacity code.
(For example, 0012 is for the 027 type.) - See the CODE No. list.
(6) Push the
button. (The display should change from flashing to steady.)
(7) Push the
button to bring the system back to normal off state.
5
Next, write any setting changes made on-site after installation, such as address settings, in the
EEPROM. Perform the tasks specified in step 1 again.
6
Use the
button to set the CODE No. (DN code) to 01 (To set filter sign lighting time)
7
Check the value displayed with the value jotted down in Procedure 1 and information proved by
the customer.
(1) If there is a discrepancy, change the setting in accordance with the jotted-down value, and push the
button.
(The display should change from flashing to steady.)
(2) If there is no discrepancy, do nothing.
8
Use the
button to change the CODE No. (DN code).
Again, check the value, and change the setting if necessary.
9
Repeat steps 6 and 7 until all the settings are checked.
10
When finished, push the
button to bring the system back to normal off state.
In the case of group operation, turn the unit off, reconnect the indoor-indoor group control wiring and CN41
connectors, and turn on all the indoor units.
(It takes the system about 1 minute to become responsive to remote controller operation.)
* CODE No. (DN code) go from 01 to FF with a few gaps along the way.
If you realize you have wrongly corrected a certain setting after pushing the
button, you can recover the initial
value by pushing the
button, provided that the CODE No. (DN code) is yet to be changed.
