INFORMATION
The software is equipped with an "installer-on-site" mode
([4‑0E]), that disables automatic operation by the unit. At
first installation, setting [4‑0E] is by default set to "1",
meaning automatic operation is disabled. All protective
functions are then disabled too. To enable automatic
operation and the protective functions, set [4‑0E] to "0".
12 hours after the first power-on, the unit will automatically
set [4‑0E] to "0", ending "installer-on-site" mode and
enabling the protective functions. If – after first
installation – the installer returns to the site, the installer
has to set [4‑0E] to "1" manually.
