FUNCTION
The Autoadapt function antuomatically control the
pump performance within the specifi ed perfor-
mance range. (1) Adjusting pump performance ac-
cording to the system sizing; (2) Adjusting pump
performance according to the variation of load his-
tory. When it comes to autoadapt, the control mode
of the pump is propotional pressure control. Best
energy effi cient mode.
The operating performance point of the pump moves
forward or backward along the the Min. propotional
pressure curve, depending on the heat demand. The
pressure of pump decreases at falling heat demand
and increased at rising heat demand.
The operating performance point of the pump moves
forward or backward along the the Max. propotional
pressure curve, depending on the heat demand. The
pressure of pump decreases at falling heat demand
and increased at rising heat demand.
Based on the heat demand of the system. the oper-
ating performance point of the pump move in or out
the Min. constant pressure curve. The pressure of
the pump stay remain, irrespective of the fl ow.
Based on the heat demand of the system. the oper-
ating performance point of the pump move in or out
the Max. constant pressure curve. The pressure of
the pump stay remain, irrespective of the fl ow.
The pump runs at certain speed and performes a
constant curve. For rate III mode, it means the pump
performes the Max. curve under all operating con-
ditions. To set the pump to rate III mode for only a
short period of time means rapid pump venting.
Highest energy consumption mode.
The pump runs at certain speed and performes a
constant curve. For rate II mode, it means the pump
performes the Medium curve under all operating
conditions.
The pump runs at certain speed and performes a
constant curve. For rate I mode, it means the pump
performes the Min. curve under all operating condi-
tions. Smallest energy consumption mode.
The night mode is activated under certain condi-
tions, where the pump runs with minimum perfor-
mance and energy consumption. Smallest energy
consumption mode. This mode can be activated only
when pump is installed on supply piping.
