NOTICE
NEVER operate the unit without thermistors and/or
pressure sensors/switches. Burning of the compressor
might result.
INFORMATION
The software is equipped with an "installer-on-site" mode
([9.G]:
Disable protections ), that disables automatic
operation by the unit. At first installation, setting Disable
protections is by default set to Yes , meaning automatic
operation is disabled. All protective functions are then
disabled. If the user interface home pages are off, the unit
will NOT operate automatically. To enable automatic
operation and the protective functions, set
Disable
protections
to
No
.
36 hours after the first power-on, the unit will automatically
set
Disable protections to No , 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
Disable protections to Yes manually.
