Troubleshooting the Outdoor Unit SiAUY361411EA
125 Troubleshooting
1.5 Main Operations in Servicing
Caution • If you are instructed to reset the outdoor unit's power supply, after turning off the power, make
sure that none of the LEDs on the circuit board are lit before turning the power back on.
• After completing inspection or repair, be sure to perform sufficient actuator checks and test
runs to ensure that operation is normal.
1.5.1 Test Run
„
Configuring the memory switches
You can change the preconfigured settings (factory defaults) by selecting "3. Configure items" in
the STOP mode. For information on how to change the memory switches, see
page 114 [How
to Use the Checker on PCB] and page 121 [STOP Mode] .
• You can configure the quiet mode, energy saving mode, snow sensor, periodic inspection
reminder and other settings.

Clearing the error code (alarm)
If trouble or a failure occurs during operation and the system stops with an error code
(alarm) shown, follow the steps below to clear the alarm display.
There are four ways of clearing the alarm display. Clearing the alarm display not only clears the
alarm shown on the outdoor unit but also resets the warning counter simultaneously.
[Clearing the alarm display from an indoor unit remote controller]
Stop one or more indoor units by turning the RUN switch from ON to OFF. (If the alarm display
is latched (retained) to all the indoor unit remote controllers, however, only the alarm display for
the indoor unit on which you turned OFF the RUN switch will be cleared.)
[Clearing the alarm display from the onboard checker]
1. Using the onboard checker (Checker on PCB), press and hold down for 3
seconds or longer when the unit is running or alternately showing the total operated hours
and an alarm to clear the alarm.
2. With the onboard checker set to the STOP mode, select "1. Alarm display" and, when an
alarm is shown, press and hold down for 3 seconds for longer. (However, if the
alarm display is latched (retained) to all the indoor unit remote controllers, the remote control
unit showing the alarm must be turned OFF.)
[Clearing the alarm display from a monitor communication device]
Send a "Clear Alarm" signal from a PC or other device to the outdoor unit according to the
specifications of the monitor communication device. (However, if the alarm display is latched
(retained) to all the indoor unit remote controllers, the remote control unit showing the alarm
must be turned OFF.)
[NOTE] Clearing the alarm display from an indoor unit remote controller may not be possible
depending on the error code (alarm). In this case, clear by turning the power off and
then back on.
„
Rewiring the communication cables between the outdoor and indoor units
If you have changed the number of connected outdoor or indoor units, or performed any
operation related to the communications between outdoor and indoor units (such as circuit
board replacement), with all the units and devices for which you want to establish
communications powered on, perform rewiring on one of the outdoor units.
[Rewiring method]
Press and hold down SW2 (Rewire Checker button) located on the main circuit board for 5
seconds or longer.
Make sure that the dot next to the left digit of the 7-segment hour meter display starts double
flashing.
