Ctl Control period
Smaller value will result in higher control accuracy.
For SSR output, generally 0.5 to 3 seconds.
For Relay output, generally 15 to 40 seconds, because small value will
cause the frequent On-Off of mechanical switch and shorten its service
life. Ctl is recommended to be 1/4 – 1/10 of derivative time. When
control under on-off control, Ctl is used as delay time to restart to
protect the compressor.

Scb Input shift
Scb is used to make input shift to compensate the error produced by
sensor or input signal.
PV after compensation= PV before compensation + Scb.

FIL PV input filter
Higher degree of FIL gives more powerful noise filtering.
Large FIL value stabilized the input signal but the system response
speed will be slow. Generally speaking, 1 to 3 will be used.
If great interference exists, FIL can be gradually increase to limit the
momentary fluctuation among 2 to 5 unit.
When the instrument is being metrological verified, FIL should be set to
0 or 1 to minimize the response time.
