7.4.4. Installer
The installer menu should be accessed only by qualified personnel. Some of the set
points that can be regulated from this menu can have large effects on the unit perfor-
mance depending on the type of commissioning and installation. There should be a
proper match between installer set points and type of installation in order to optimize
the performance and lifetime of the unit.
In order to access the Installer Menu, a 4-digits password needs to be entered. The
password is: 2016. All temperatures are expressed in °C.
