Service Menu
The service menu provides functions for use by installer or service engineer. It is not intended the home owner alters
settings within this menu. It is for this reason password protection is required to prevent unauthorised access to the
service settings.
• From the main setting menu use F2 and F3 to highlight the service icon then press CONFIRM.
• You will be prompted to enter a password. THE FACTORY DEFAULT PASSWORD IS "0000".
• Press CONFIRM. (It takes up to 30 seconds to load the service menu.)
• To reset the password hold down F3 and F4
The service menu is navigated using the F1 and F2 buttons to scroll through the functions. The menu is split across
two screens and is comprised of the following functions;
1. Manual operation

7. External input settings
8. Running information

10. Summary of settings

In this Installation Manual, instructions will be given only for the following functions;
1. Manual operation

Note:
Many functions cannot be set whilst the indoor unit is running. The installer should turn off the unit before trying to
set these functions. If the installer attempts to change the settings whilst the unit is running the main controller will
display a reminder message prompting the installer to stop operation before continuing. By selecting "Yes" the unit
will cease operation.
