Proceed as follows to enter the installer password from the "Home Screen":
1. Keep pressing the "arrow down" key until the
"200# Settings" menu is displayed.
2. Press <ENTER>.
3. Keep pressing the "arrow down" key until the
"280# Password Setting" menu is displayed.
4. Press <ENTER>.
☑ The "280# Password Setting" sub-menu opens.
5. Press <ENTER>.
6. Determine the password. Calculate the checksum
(sum of all digits) of the operating hours. In the
message shown here:
1 + 2 + 3 + 4 + 5 + 6 = 21
7. Enter the password by pressing the up/down arrow buttons.
8. Confirm the password by pressing <ENTER>.
☑ The installer password has been entered.
Operating level [1] = the installer level is set.
9. Exit the menu by pressing the <ESC> key.
Switching operating levels
• If the password is invalid, the Sunny Island does not switch to the installer level. In this case,
recalculate and re-enter the installer password as described in this section.
The installer level is switched back to the user level if:
• the Sunny Island is switched off and on again.
• specific parameters are entered (e.g. the "510.01 InvRs" parameter) that cause a restart.
• an incorrect password is entered.
• no activity takes place within five minutes.
