bit11～bit12：not useful
bit13～bit14 auto tune PID
mode (valid in critical
oscillation mode)
00：PID control
01：PI control
10：P control

S3+3
Proportion Gain (Kp)
Range：1～32767[%]
S3+4
Integration time (TI)
0～32767[unit: 100ms]
0 is taken as no
integral.
S3+5
Differential time ( TD)
0～32767[unit: 10ms]
0 is taken as no
differential.
S3+6
PID operation zone
0～32767
PID adjustment band
width value
S3+7
Control death zone
0～32767
PID output value
will not change in
death zone
S3+8
Sampling temperature
filter coefficient
0～100[%]
Filter the input
sampling
temperature in
advanced mode, 0 is
no input filter
S3+9
Differential gain( KD)
0～100[%]
Only for advanced
mode (normal mode
default value is
50%), 0 is no
differential gain
S3+10
Upper limit value of
output
0～32767
S3+11
Lower limit value of
output
0～32767
S3+12
Change of Unit
Temperature Corresponds
to Change of AD Value
full scale AD value *
（0.3~1%）
default value is 10
16-bit no sign, only
for step PID
S3+13
PID auto tune overshoot
0：enable overshoot
1： not overshoot（try to
reduce the overshoot）
only for step PID
S3+14
Current target value
adjusting percentage
every time in auto tune
end transition stage
Cannot adjust
16-bit no sign, only
for step PID
S3+15
Number of times
exceeding the target value
in auto tune end transition
stage when limiting the
overshoot
only for step PID,
default value is 15
S3+16
