Description
For the "constant pressure" control mode, there is
the option to choose between two different ways of
determining the base-load pump
1) Cascade – the base-load pump is always the
pump that is started first
2) Vario – the base-load pump is always the pump
that is started last
Can only be changed when the drives are switched off.
Number of pumps that are started when the system
is started after a standby. The optimal number of
pumps is subsequently set automatically.
This can be used to meet high water demands more
quickly. The number cannot be greater than the
maximum number of pumps that are to be running
simultaneously.
The parameter menu for all settings that influence
operation
The setting menu for setpoints 1 and only in EXPERT
menu for setpoint 2 as well
The first setpoint.
In the p-v control mode, this value corresponds
to the setpoint at maximum volume flow (menu
1.2.1.3). The initial value depends on the pump
being used.
The second setpoint.
In the p-v control mode, this value corresponds
to the setpoint at maximum volume flow
(menu 1.2.1.3). The initial value depends on
the pump being used.
The maximum volume flow for the system. When
current volume flows are equal to or greater than
this value, the setpoint for maximum volume flow
(menu 1.2.1.1 or 1.2.1.2) is used. If the value is set to
zero, the control device calculates the maximum
volume flow automatically.
The factory setting is set depending on the pump.
The setpoint in the event of zero flow relative to the
setpoint at maximum volume flow.
The initial value depends on the pump being used.
