Note!
The
4-point characteristic

Adaptation
function is not
active (CO1, 2 -> F08 - 0).
5.2
Fixed set point control
During the times-of-use, the flow temperature can be controlled according to a fixed set
point. Outside the times-of-use, the controller regulates to a reduced flow temperature.
Set the desired rated flow temperature as
Day set point, and the reduced flow temperature
as
Night set point.

Note!
A fixed set point control in heating circuit 2 with CO2 -> F02 - 0 can only be configured if
CO1 -> F02 - 0 is set as well, because the heating circuit 2 with CO2 -> F02 - 0 only uses
the measured outdoor temperature provided by heating circuit 1.
