Setting the display
Start-up delay
The start-up delay is the time delay between the bus
voltage recovery and the device's functional start. Set a
time after which the current values can be read by other
KNX devices.
Communication objects
You can select the following communication objects:
Here, you set the display options and display functions:
• You can disable the control menu so that the menu
buttons cannot be used to make further changes to
the settings.
• You use the display mode to specify which values you
want to display on the basic display (actual tempera-
ture, setpoint temperature, time, date, external tem-
perature and fan speed). You can display these
values either individually or in alternation. You can
also set the display rhythm for alternating displays.
The display mode can also be set using the control
menu on the push-button.
• For the weekday display, you can set day "1". This
means that the first weekday can be defined as: Fri-
day, Saturday, Sunday or Monday. Each weekday is
then shown in the display with a different number ac-
cordingly.
• Time format and unit of temperature display (Celsius/
Fahrenheit).
• The background lighting on the display can either be
switched off or on at all times, or can be switched on
during operation. You can also set the persistence pe-
riod and the brightness of the background lighting.
|
The parameters for the background illumination
and display mode can be changed using the menu
buttons on the push-button (see operating instruc-
tions).
If you use room temperature control ("Control general"
tab), additional possible settings appear:
• You can specify whether or not the operation mode
can be changed when the frost or heat protection op-
eration mode is activated.
• "Access menu setpoint temperature/operation mode
directly" Here, you specify which operation mode you
want to select with a short push of a button on the
menu buttons. You can choose between the control
menu "Set setpoint temperature" or "Set operation
mode".
• On the display, a symbol can show either the current
controller status or whether heating or cooling is acti-
vated.
