This menu contains all the settings which can be adjusted by the user of the system.

Since the display is the biggest consumer, while it is not
being operated, it switches into a power-saving mode (only
displaying the time and date).
In the interests of saving even more power to increase
battery life, the parameter [LCD Status] will switch off the
display altogether when the controller is in certain states:
1: Display ON
2: Display ON, with heating programme enabled
3: Display ON, if demand exists for heating
4: Display ON/OFF with time interval (10s OFF/ 5s ON)
5: Display OFF
If a control is operated, the display switches back on
automatically.
*) OV = Own values: space to enter you settings for each parameter in the system
