7.1.1 System data menu
Settings for the entire heating system can be made in this
menu. For example, the value for the minimum outside
temperature or the thermal storage capacity of the heated
building can be set here. Additional settings for heating
circuit 1 and DHW system I are available in this menu (if directly
connected to the heat source).
