24 Rittal enclosure cooling unit
7Operation
7.1 General
The cooling unit is equipped with a touch function dis-
play for making basic settings and displaying error mes-
sages. This is an industrial-grade touch display which is
pressure-sensitive and may therefore be operated with
gloves.
As well as operating directly on the cooling unit itself,
there is also a smartphone app available. This offers al-
most the same functions as the actual display, and ad-
ditionally provides extended explanations of error mes-
sages, as well as the option of contacting the Rittal Ser-
vice team directly.
7.2 Layout of the display
The display is divided into a top section on a dark back-
ground, and a bottom section with the menu bar. This
layout is always identical, but the content of the two sec-
tions will vary according to the menu selected.
7.2.1 Start screen
The start screen is always displayed while the cooling
unit is in normal operation, provided there are no error
messages.
