WELCOME BACK OBJECT
Z41 Pro / Lite / COM can send a specific object (the
welcome back object
) to the KNX
bus when the user presses a touch button after a significant amount of time since the
last press. Sending it or not can also depend on an
additional, configurable condition
consisting in the evaluation of up to five binary objects.
The welcome back object can consist in a
one-bit
value or a
scene
value (or both),
depending on the parameterisation.

WELCOME GREETING
This function permits showing the user a welcome message of up to four lines of text on
the display, each of which can be object-dependant or set in parameters.
When a “1” is received through the welcome greeting one-bit object, the display will
become blank and show the welcome text. The same will happen if any of the 14-byte
objects that define the text lines receives a new value from the bus.
2.8
BACKLIGHT
It is possible to configure brightness user-defined levels for the display of Z41 Pro / Lite
/ COM. Two operation modes are available: the
normal mode
and the
night mode
. The
second one is optional. It is provided for temporary situations and environments where
an excess of brightness may disturb the user. In such cases, it will be possible to switch
the mode by means of a one-bit object and/or a scene object.
In order to prevent unnecessary power consumption while the device is idle in normal
mode, the backlight of the screen is partially faded out after a few minutes without any
user interaction. After that, if the inactivity persists for a few more minutes, the backlight
is completely turned off. While partially or totally faded out, any press on the screen will
bring back the normal light level.
The timings for the above behaviour may differ in case a pop-up window is open, as well
as depending on the configuration set in parameters (see section 3.2.3 for details).
The behaviour is different during night mode. When this mode is active, brightness level
established by parameter will remain constant but it is possible to define a specific
