The summer / winter heating limit is used to switch the heating on and off in the course
of the year, depending on the temperature conditions. In "Automatic" mode, switching
on / off takes place automatically, so there is no need for the user to do this manually.
By changing the setting, the respective periods of time will be shortened or extended.

The 24-hour heating limit is used to switch the heating on and off in the course of the
day, depending on the outside temperature. This function is used primarily during
intermediate seasons (spring and autumn), enabling the system to respond to short-
time temperature variations.
