Minimum outside temperature
The minimum outside temperature is a statistically calculated average value
of the coldest outside temperatures over the past few years. It influences the
gradient of the heating curve (colder: shallower heating curve; hotter: steeper
heating curve).
Call up the service level. "Gen. parameters" is shown as the first main menu.
Press "Display" to call up a submenu (here: "Min outside temp").
The display shows the selected submenu.
Hold down "Display" and turn the rotary selector until the required value
appears (here: "-12°C").
The display shows the set value.
Release "Display" to save your input.

USER INFORMATION
Determine the minimum outside temperature for your region (average value)
from Tab. 3, page 29.
If your region is not included in the table, take the value from the heat demand
calculation for your building.
