Reading and editing
values
In order to edit values, you must have Write access rights. If you
only have Read access, you can view a value, but not modify it.
In the example below, the values which you can edit are indicated as
follows:
Figure 6-1 Display and direct access keys
Key:
Arrowhead
The arrowhead symbol at the end of a line indicates
that you have the necessary Write access rights to edit
this value. You can use the direct access key to switch
to Edit mode (press briefly) or to navigate to the next
level down (sustained pressure). If there is no
arrowhead symbol adjacent to any of the other values,
this means that you have no access to these values.
Direct access key
To edit the value
Setpoint for cooling
, press the
direct access key adjacent to the line concerned.
Note
As the procedure described below is always the same, it is only
described once, in order to keep this manual as easy to read as
possible. If you are required to edit a value in any subsequent
routines, the procedure referred to is the one described here.
To keep the manual as clear as possible, the instruction "Press the
direct access key" is not repeated.
Example: "Select the month and the year".
