Restoring the time phases to the factory settings
Note
The time phases are only restored to the factory set-
tings when you reset
all
settings for the selected heat-
ing circuits.
The steps for restoring factory settings can be found
on page.
Heating curve
Adjusting the heating curves
■
You can alter the heating characteristics if the room
temperature does not meet your requirements for
any prolonged period of time.
■
You alter the characteristics by changing the slope
and level of the heating curve. For more information
regarding the heating curve, see page.
■
Please observe the modified heating characteristics
over several days (if possible, wait for a major
change in the weather) before making further adjust-
ments.
Changing the slope and level
For assistance, use the following table.
Heating characteristics
Measure
Example
The living space is
too cold during the
cold season
.
Adjust the heating curve
slope
to the
next
highest
value (e.g. 1.5).
Slope
1.5
Level
0 K
The living space is
too hot during the
cold season
.
Adjust the heating curve
slope
to the
next
lowest
value (e.g. 1.3).
Slope
1.3
Level
0 K
The living space is
too cold during
spring/autumn
and during the
cold
season
.
Adjust the heating curve
level
to a
higher
value (e.g. +3).
Slope
1.4
Level
3 K
The living space is
too hot during
spring/autumn
and during the
cold
season
.
Adjust the heating curve
level
to a
lower
value (e.g.
−
3).
Slope
1.4
Level
-3 K
The living space is
too cold during
spring/autumn
, but warm enough dur-
ing the cold season.
Adjust the heating curve
slope
to the
next
lower
value and the
level
to a
higher
val-
ue.
Slope
1.3
Level
3 K
The living space is
too hot
during
spring/autumn
, but warm enough dur-
ing the cold season.
Set the heating curve
slope
to the
next
higher
value and the
level
to a
lower
val-
ue.
