Menu 9.2.2 Flow diff HP
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.
