Abb. 9-1 Parameter heating circuits, boost mode
The function "Boost mode" is released separately for each heating circuit.
Influence of the deviation between set point and actu-
al value of room temperatures on flow temperature
The boost mode function is allowed. Should be indivi-
dual for each circuit.
The expected return temperature outside of the
heating-up phase is a result of a re-calculation of the
heating curve with a reduced slope. The percentual
reduction of slope is set here.
The expected return temperature has to be undercut
at least for this time span (see also BOO3)
at least for this value
The deviation to the expected return temperature
multiplied with compensation factor gives the increase
of the flow temperature (boost mode) for the time
defined in BO05
Time period for the boost mode
