730 1030 1330 Summer/winter heating limit
The summer/winter heating limit is used to switch the heating on and off in the course
of the year, depending on the outside temperature. In Automatic operation, switching
on/off takes place automatically, so there is no need for the user to do this manually.
The respective periods of time are shortened or extended by changing the setting.
The Summer/winter changeover function switches the heating off when the attenuated
outside temperature exceeds the adjusted changeover temperature.
The heating switches back on when the attenuated outside temperature drops below
the set value minus 1 K.
The required changeover temperature can be parameterized. The function can be
activated/deactivated.
Increase: Winter operation will start earlier.
