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
temperature conditions. In automatic
mode, switching on / off takes place
automatically, so there is not need for
the user to do this manually. By chang-
ing the setting, the respective periods
of time will be shortened or extended.
Increase:
Winter operation will start earlier.
Summer operation will start later.
Decrease:
Winter operation will start later.
Summer operation will start earlier.

24-hour heating limit
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 spring and au-
tumn to respond to short-term tempera-
ture variations.
By changing the value entered, the
respective heating periods will be short-
ened or extended.
Increase: Heating mode will start
earlier. Changeover to ECO later.
Decrease: Heating mode will start later.
Changeover to ECO earlier.

Ext'n 24-hour heating limit
The 24-hour heating limit is extended
by giving consideration to the composi-
