Type of use Function
Not configured This analogue input is not used. No settings re-
quired
Setpoint sensor Use analogue input as setpoint sensor.
For example, delivery head.
Differential pressure sensor Use analogue input as actual value input for differ-
ential pressure sensor.
For example, index circuit evaluator.
Temperature sensor Use analogue input as actual value input for tem-
perature sensor.
For example for control mode T-const.
External sensor Use analogue input as actual value input for PID
control.

Table 47: Signal types
Example setpoint sensor
The following signal types are available for the type of use “Setpoint sensor”:
Setpoint sensor signal types
0 ... 10 V: voltage range of 0 ... 10 V for transfer of setpoints.
2 ... 10 V: voltage range of 2 ... 10 V for transfer of setpoints. Cable break is detected
for a voltage below 2 V.
