Menu 9.2.2 Maximal deviation from the calculated
flow heat pump
When the current flow temperature deviates from the
set value compared to that calculated, the heat pump
is forced to stop/start irrespective of the degree-
minute figure.
When the current flow temperature exceeds the cal-
culated flow by the set value, the degree-minute figure
is set to 1. The compressor stops when there is only a
heating requirement.
When current flow temperature falls below the calcu-
lated flow by the set value the degree-minute figure is
set to -60. This means the compressor will start. When
the value also falls below menu 9.2.3, the degree-
minute figure can be set to -400. The value is
adjustable between 3 and 25 °C.

the degree-minute value is set to -400. This means that
the additional heat can be engaged directly. The value is
adjustable between 1 and 8 °C.
