Configuration

By default, the AHU application is not set to autologin to the web server. To log in to the AAC20 web server, insert the IP address of the AAC20 controller in the Internet browser's address bar and confirm with Enter.

Log in using the default admin credentials:

• login: service

• password: 2468

or log in using default end user (lower level of permissions than the service user - no possibility to change configuration, only setpoints) credentials;

• login: user

• password: 1357

Remember to copy necessary web server files to the controller's SD card (files from the selected AHU application example\Generation Output Files folder folder) and flash memory (index.html) in order for the web server to work properly. More on using the AAC20 web server is available in the Visualization Web Server user manual.
