Proportional control(P-band)
The proportional control function calculates the output based on the difference between setpoint and measured
value. The proportional band (P-band) defines the difference between setpoint and measured value which will
result in a 100% output. Setting the proportional band to 0 disables proportional control.

3-point floating:
For floating point outputs the running time of the actuator used needs to be specified with FC17. Running time is
defined as the time required for the actuator to run from fully open to fully closed and vice versa. Actuators with a
fixed running time are recommended. Once fully open or fully closed the running time for the actuator is extended
for a full run-time cycle. This will allow the actuator position to be synchronized in case it has been moved during
off time or an actuator with variable running time was used.
Pulse With Modulation (PWM)
In PWM mode the digital output will be switched on/off once per cycle. The on and off times are calculated
according to the control sequence.
