External setpoint source
Visible if an external setpoint source (analogue input or CIF mod-
ule) was selected previously in the context menu.
Temperature sensor T1
Visible for active control modes, which require a temperature
sensor as actual value (constant temperature).
Temperature sensor T2
Visible for active control modes, which require a second temper-
ature sensor as actual value (difference temperature control).
Free sensor input
Visible for user-defined control.
External delivery head sensor
Visible for index circuit evaluator Δp-c, which requires a differen-
tial 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" [} 179] table).
Q-Limit
Max
Visible for active control modes, which support additional control
function "Q-Limit ". (see "Pre-defined applications in the setting
Max
assistant" [} 179] table).
Q-Limit
Min
Visible for active control modes, which support the additional con-
trol function "Q-Limit ". (see "Pre-defined applications in the
Min
setting assistant" [} 179] 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.
PID: Inversion
Visible for user-defined PID control.
Pump On/Off
Always visible.

Description
Linking the setpoint to an external setpoint 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 con-
trol.
Setting the sensor for user-defined PID control.
Setting the external sensor for the delivery 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.
Setting the inversion for the user-defined PID control.
Switching the pump on/off with low priority. A MAX, MIN, MANUAL
override switches the pump on.
