Recommended values for the slope
of the heating curve
Heating curve setting in “Slope” mode
Below, you can see the family of heating curves that
can be set with the slope value and the selected room
temperature.
The flow target temperatures determined from this
heating curve are limited by the values “T.Pre.MAX”
and “T.Pre.MIN”, which means that if the flow target
temperature is greater than “T.Pre.MAX”, it will be
changed to “T.Pre.MAX”. If it is less than “T.Pre.MIN”,
the heating circuit will be switched off.
Recommended values for the slope of the heating
curve are provided in the
table to the right
.

Heating curves in “Slope” mode for various target room temperatures
Example
:
The target room
temperature is
set to 20°C and
the slope to 1.5.
The flow temper-
ature is then
controlled when
the outdoor tem-
perature is 15°C
to 30°C. When
the outdoor tem-
perature is 0°C,
the flow tempera-
ture is regulated
to 50°C.
a) Setting the lowered temperature:
In the function overview, turn the rotary wheel until
“HEAT CIR.1 F:16” is selected with the pointer.
Press the rotary wheel. In the heating circuit
menu, also select the entry “T.Room.LOWER:”.
Now turn the rotary wheel until the required value
appears and press it again to save the lowered
temperature.
For optimum savings you can always set
“T.Room.LOWER” 4 – 5 K lower than the
target room temperature.
You can set the target room temperature in the
heating times menu (“TIME PROG.:”) (
item 2, p. 35
).

In the heating curve menu, turn the rotary wheel
until “Slope” (

) is selected by the
pointer. The slope can be set by pressing and
turning the rotary wheel until the required value
appears and then pressing it again.
