Setting the control functions
Settings menu
Setpoint temperature (ΔT-c)
Visible for active control modes, which re-
quire an absolute temperature difference
as setpoint.
Setpoint speed
Visible for active control modes, which re-
quire speed as setpoint.
Setpoint PID
Visible for user-defined control.
External setpoint source
Visible if an external setpoint source (ana-
logue input or CIF module) was selected
previously in the context menu.
Temperature sensor T1
Visible for active control modes, which re-
quire a temperature sensor as actual value
(constant temperature).
Temperature sensor T2
Visible for active control modes, which re-
quire a second temperature sensor as ac-
tual value (difference temperature con-
trol).
Free sensor input
Visible for user-defined control.
External delivery head sensor
Visible for index circuit evaluator Δp-c,
which requires a differential pressure as
actual value.
No-Flow Stop
Visible for active control modes, which
support the additional function "No-Flow
Stop" (see "Pre-defined applications in
the setting assistant" [} 198] table).
Q-Limit
Max
Visible for active control modes, which
support additional control function "Q-
Limit " (see "Pre-defined applications in
Max
the setting assistant" [} 198] table).
Q-Limit
Min
Visible for active control modes, which
support the additional control function
"Q-Limit " (see "Pre-defined applica-
Min
tions in the setting assistant" [} 198]
table).
Emergency operation speed
Visible for active control modes that reset
to a fixed speed.
PID parameter Kp
Visible for user-defined PID control.
PID parameter: Ki
Visible for user-defined PID control.
PID parameter Kd
Visible for user-defined PID control.
Description
Setting the setpoint of the temperature
difference for the control mode "Constant
temperature difference (ΔT-const)".
Setting the setpoint of the speed for the
control mode "Constant speed (n-const)".
Setting the setpoint of the user-defined
control via PID.
Linking the setpoint to an external set-
point source and setting the setpoint
source.
Setting first sensor (1), which is used for
temperature control (T-const, ΔT-const).
Setting the second sensor (2, ΔT-const)
used for temperature control.
Setting the sensor for user-defined PID
control.
Setting the external sensor for the deliv-
ery head with index circuit evaluator.
Setting automatic detection of closed
valves (no flow).
Setting an upper threshold of the volume
flow.
Setting a lower threshold of the volume
flow.
The pump automatically switches to this
constant speed if the set control mode
fails (e.g. sensor signal fault).
Setting the Kp factor for the user-defined
PID control.
Setting the Ki factor for the user-defined
PID control.
Setting the Kd factor for the user-defined
PID control.
