Parameter 26 - Night temperatur (standard value)
Setting range:
5.0. . . 30.0 °C
Factory setting:
16.0 °C
Application:
Determination of the set back standard room temperature - sim-
ple adjustment for all set back room setvalues in case of other
occupation situations (e.g. change of tenents or owner)
This parameter determines the desired room temperature when
operated in operational modes

Parameter 27 - Heating curve adjustment
Setting range:
0,2. . . 3.5
Factory setting:
1,75
Application:
Adaptation of the heating power to the object to be heated in
accordance with the corresponding climatic zone and the con-
struction specific conditions.
This parameter determines the slope of the heating curve.
The adjustment of the heating curve depends on the type of
installation and determines which flow temperature will be achie-
ved at the respective outside temperature.
The slope determines by how many degrees the flow temperatu-
re changes, if the outdoor temperature rises or drops by one
degree.
Notes:
Possible corrections should always be made in
small steps of 0.1!
With pure room control (parameter 4 - room
factor = RC) this parameter is ineffective!
