3.3 Operating buttons
The three operating buttons can be used to control the functions of
the device.
Use the [Set] button to configure the set temperature.
Use the [Menu] button to pull up the menu, in order to con-
figure settings.
Use the[Stop] or [Start] button to switch the device to standby
or operation mode.
The device supports two operating modes.
In Standby operation mode, the device's pump and tem-
perature control unit are turned off. Power is supplied to the
display on the device. This operating mode is suitable for
adjusting settings, for example.
In Operation mode, the components of the device are acti-
vated.
Use the [Display] button to switch back and forth between the
home screen and the display window for warnings (only pos-
sible if a warning has been generated by the device).
Use the [Down] and [Up] arrow buttons
to navigate through the menu and/or
change set values.
Use the [OK] input button to confirm the selection in the dis-
play.
Use the[ESC] menu item to navigate one window back in the
menu.
If no entry is made in the home screen for 10 seconds, the
operating button configuration will fade out and the tem-
perature display will be magnified in the display. If you press on
any one of the operating buttons, they will darken again.
If no entry is made in the menu for 30 seconds, then the dis-
play will return to the home screen.

tions, such as set temperature, on a PC. You can develop and use
your own programs for controlling the device.
