5-3. Normal Display Operations and Functions
Normal display functions
 Connect the special service checker wiring to the outdoor unit PCB.
The connection is shown in the figure below.
* It is not necessary to disconnect the communications line in the inter-unit control wiring if it has already been
connected at this time.
* Setting modes 1 and 2 can be used even when the outdoor unit is independent (when 1 maintenance remote
controller is connected to 1 outdoor unit and automatic address setting for the indoor units has not been com-
pleted).
* Displays the overall system status for that refrigerant system.
All units start/stop (Fig. 1)

The
 button can be used to start and stop all the indoor units.
 The LED turns ON when 1 or more indoor units is operating.
 The LED blinks when an alarm has occurred at 1 or more indoor units
during operation.
Switching between cooling/heating (Fig. 1)

The
 button switches between heating and cooling modes.
 The specifications are equivalent to the heating/cooling input that was
present on earlier outdoor unit PCBs.
 The display shows the operating mode of the indoor unit with the lowest
number.
All units test run (Fig. 2)

The
 button switches test run ON/OFF for all indoor units.
 Press and hold for 4 seconds to turn ON.
“Test run” is displayed while the test run is in progress.
 Conditions of test runs that are started from the unit remote controller are
not displayed on the outdoor unit maintenance remote controller.Fig. 1

System XX = Outdoor unit system address
YY = Outdoor unit sub-bus address
The item code is displayed as 01– 08. 01 indicates the most recent alarm.
The alarm history is indicated by the alarm code. (If there have been no alarm codes, “
” is displayed.)
(4) To clear the alarm history, press the 
 button. (The outdoor unit alarm history will be cleared.)
(5) To end, press the  button. The display returns to the normal remote controller display.
5-6. Setting Modes: Setting the Outdoor Unit EEPROM
 Setting mode 1

(1) Press and hold the 
 button and  button simultaneously for 4 sec-
onds or longer.
(2) Use the temperature setting 
 and  buttons to change the item code.
The item codes and setting data are shown in the table on the next
page.

 and  buttons to change the setting data.
To confirm the changed setting data, press the 
 button.
(At this time, “Setting” stops blinking and remains lit.)
(4) During this mode, “Setting” is displayed, blinking. The outdoor unit
address display section displays “ALL,” the item code and number (DN
value in the table), and the setting data (6 digits).
(The setting data is displayed in 6 digits. The display changes between
the first 3 digits (Fig. 
A) and the last 3 digits (Fig. B).
When the first 3 digits are displayed, the top point of the colon is lit.)

6. TEST  RUN
6-1. Preparing for Test Run
Before attempting to start the air conditioner,
check the following:
(1) All loose matter is removed from the cabinet espe-
cially steel filings, bits of wire, and clips.
(2) The control wiring is correctly connected and all
electrical connections are tight.
(3) The protective spacers for the compressor used for
transportation have been removed. If not, remove
them now.
(4) The transportation pads for the indoor fan have been
removed. If not, remove them now.
(5) The power has been supplied to the unit for at least
5 hours before starting the compressor. The bottom
of the compressor should be warm to the touch and
the crankcase heater around the feet of the com-
pressor should be hot to the touch. (Fig. 6-1)
(6) Both the gas and liquid tube service valves are open.
If not, open them now. (Fig. 6-2)
(7) Request that the customer be present for the trial
run.
Explain the contents of the instruction manual, then
have the customer actually operate the system.
(8) Be sure to give the instruction manual and warranty
certificate to the customer.
(9) When replacing the control PCB, be sure to make all
the same settings on the new PCB as were in use
before replacement.
The existing EEPROM is not changed, and is
connected to the new control PCB.
