following parameters apply on selection PID only:
08: prop. band %
Control parameter "proportional band" in % of the maximum value
09: integral time
Control parameter "integral time" in seconds
10: derivat. time
Control parameter "derivative time" in seconds
11: prop. shift
Operating range of the proportional band: 0=prop. band below setpoint / 1=prop.
band one quarter above setpoint / 2=.. half above setpoint / 3=.. three quarters
above setpoint. In most applications a setting of "1" ensures best results (ie. fast
reaching the setpoint with minimum overshoot)
following parameters apply on selection C PID only:
18: prop. band %
Control parameter "proportional band" in % of the maximum value
19: integral time
Control parameter "integral time" in seconds
20: derivat. time
Control parameter "derivative time" in seconds
21: prop. shift
Operating range of the proportional band: 0=prop. band below setpoint / 1=prop.
band one quarter above setpoint / 2=.. half above setpoint / 3=.. three quarters
above setpoint. In most applications a setting of "1" ensures best results (ie. fast
reaching the setpoint with minimum overshoot)
22: hyster. units
Hysteresis of the control loop. The hysteresis is specified as absolute value. A small
value results in higher accuracy but causes higher switching rates. A large value

causes less accuracy due to larger oscillations of the process value
23: derivat. time
Control parameter "derivative time" in seconds
following parameters apply on selection D HYS only:
28: hyster. units
Hysteresis of the control loop. The hysteresis is specified as absolute value. A small
value results in higher accuracy but causes higher switching rates. A large value
causes less accuracy due to larger oscillations of the process value
29: derivat. time
Control parameter "derivative time" in seconds
30: min. ON time
Minimum time for output activation specified in seconds. Used to supress short
time output activation. A typical application is when driving certain types of
burners which need a minimum startup time (ignition sequence)
31: min. OFF time
Minimum time for output deactivation specified in seconds. Used to supress short
time output deactivation. A typical application is when driving certain types of
burners which should not be interrupted for short periods
following parameters apply on selection P DIR only:
38: lower val.base
Sets the lower base value which corresponds to 0% control loop output
39: upper val.base
Sets the upper base value which corresponds to 100% control loop output
