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, this
Set point is reduced by the Set-back difference.
The fixed set point control is activated when there is no outdoor sensor AF connected to the sys-
tem or when it has been configured in the function block
Type of characteristic
. In the case that
the fixed set point control is configured and an outdoor sensor is connected, the outdoor tem-
perature is displayed in the InF5 level. The outdoor temperature does not have any effect on the
control loop.
