1.1 Appearance
The controller has a 7-inch true color touch-sensitive LCD that provides a user-friendly
interface for you to perform query, settings, monitoring, and maintenance.
The indicator on the panel displays operating status of the precision air conditioner. Figure 1-1
shows the location of the indicator. Table 1-1 lists the relationship of the alarm status,
indicator, and buzzer. If critical alarms, major alarms, and warning alarms are generated
simultaneously, the indicator and buzzer show the status of the alarm with the highest severity
level.

3.2 Initial Configuration
When configuring the temperature and humidity parameters, do not place the cursor
between the decimal point and the following digit of the value. Otherwise, the decimal
point cannot be deleted, and the parameter value fails to be configured.
To ensure the security of user information, you need to import a certificate and key before
using the controller, and periodically update the certificate and key. For details about how
to import a certificate and key, see 5.13 Importing a Certificate and Key.
3.2.1 User Right Authentication
To enhance security, before a user attempts to perform setting and maintenance operations, the
user needs to enter the user name and password for right authentication. Figure 3-2 shows the
setting login screen for an example.
Figure 3-2 Screen for logging in to the settings screen
Users includeAdmin, Engineer, Operator, and Guest. The Admin users have the highest
permission, followed by the Engineer, Operator, and Guest users. The initial passwords
for theAdmin, Engineer, and Operator users are all 000001. The Guest user does not
have a initial password.
To ensure system security, a user needs to change the initial password after initial login.
For the password change method, see 5.3 How to Change a Password. If the login
password is forgotten, refer to 5.4 How to Restore the Initial Password to restore the
initial password.

After login to the system using a user name, the user right is valid when you touch the
screen all the time. If you do not touch the screen, the user right is only valid for 3
minutes. To ensure security, manually log out by tapping at the right corner of the
home screen.
A Guest user can only be used for querying information. Log in as other types of users if
attempting to set parameters or perform maintenance.
Determine the parameter modification for the Admin or Engineer user with Huawei. Huawei will not be
liable for any consequence caused by modification without permission.
3.2.2 Start and Shutdown
Context
Tap the Start or Shutdown buttons on the home screen to start or shut down the precision air
conditioner.
Procedure
Step 1 Tap Start or Shutdown on the home screen. A warning is displayed, indicating whether to
start or shut down the precision air conditioner, as shown in Figure 3-3. Tap Yes. If the device
is successfully started or shut, the system displays a message, indicating that the command is
successfully triggered.
Figure 3-3 Start and shutdown
If a power failure occurs and the precision air conditioner is powered on again, the precision air
conditioner automatically restores to the original state (start or shutdown) before the power failure.
The hardware port for controlling the status of the remote dry contact or On/Off status on remote
is reserved on the ACC. The status of the remote dry contact and On/Off status on remote is on by
default.
The operations that start the air conditioner successfully by the LCD button or by element
management system (EMS) is effective only when the remote dry contact or On/Off status on
remote is on the status of on.
In start mode, the Start button is green (unavailable) and the Shutdown button is gray (available).
In shutdown mode, the Shutdown button is green (unavailable) and the Start button is gray
(available).
