EXTERNAL INFORMATION
When the heat pump door is closed, information can be received via an
information window and a status lamp.
Information window
Status lamp
Information window
The information window shows part of the display that is on the display
unit (located behind the door to the heat pump). The information window
can display different type of information, e.g. temperatures, clock, etc.
You determine what is to be displayed in the information window. Your
own combination of information is entered using the display unit. This
information is specific to the information window and disappears when
the heat pump door is opened.
Instructions on how to set the information window can be found on page
69.
Status lamp
The status lamp indicates the status of the heat pump: continuous green
light during normal function, continuous yellow light during activated
emergency mode or continuous red light in the event of a deployed
alarm.
