6.2. Outdoor Unit Errors
Current errors of the outdoor unit are displayed in the last position of the main menu of the
SCMI-01.4 module. The first line contains the title
Error
and the second line contains four
two-digit hexadecimal error codes (or the sum of these codes, if multiple errors occur). After
eliminating the displayed errors, this item will cease to be displayed. To view already not
displayed errors, you should press
ESC
and
ENTER
keys simultaneously, when the default
screen of the SCMI-01.4 module is displayed. You must press these keys in the given order,
i.e. first press and hold
ESC
key and then press also the
ENTER
key. The display shows:
Err -1
AABBCCDD
The number –
1
after the title
Error
identifies the last (previous) error and the second line is
the same as when displaying the current error, i.e. four two-digit hexadecimal error codes (or
the sum of these codes, if multiple errors occur). You can use the ▼/▲ keys to display other
previous errors with numbers from
–2
to
–8
, i.e. it is possible to display up to eight previous
errors. If the number of errors stored in the SCMI-01.4 module memory is lower than 8,
horizontal dashes will be displayed instead of error codes in the empty positions. If the
number of previous errors exceeds 8, all stored error records are shifted and the oldest one
is deleted. In this way, the error list is updated whenever a new error occurs and it cannot be
deleted nor changed by another way. Summary of errors is given in the following tables:
