Loc=0: Allowed to modify parameters and do AT
Loc=1: Allowed to modify parameters but cannot AT
Loc=2: Allowed to modify parameters and AT
Loc=4-255: NOT allowed to modify parameters ecept Loc.
Loc=808, Set to 808 and press

Avoid wrong frequent alarm caused by wrong value setting
AoP is to define the place of HIAL,LoAL,HdAL alarms like :
Value 0~4.0 means never alarm, 3and4 mean alarm from
AU1,AU2.
E.g. AOP=403 means HIAL alarm from AU1, HdAL from AU2.LoAL
no alarm
onoF : On-off control, used in normal case
APld: high precision control PID mode
nPld: standard PID control
Run, normal running status, PRG light on
Stop, stop status,below windo shows "stop",PRG light out
Hold, keep current status, program stop counting time at this
moment
rE:Reverse acting.Increase in measured variable causes a
decrease in the output,such as heating control.
dr:Direct acting.Increase in measured variable causes an
increase in the output,such as refrigerating control.
rEbA:Reverse acting with low limit alarm and deviation low
alarm blocking at the beginning of power on.
drbA:Direct acting with high limit alarm and deviation high alarm
blocking at the beginning of power on.
Proportional band in PID with unit℃/F.
Notes:normally use At to confirm P,I,D and Ctl .But can set
known correct value.
Time of integral in PID.No integral effect when I=0 unit is 1
second
Time of derivative in PID.No derivative effect when d=0. Display
unit is 0.1second
Small value can improve control accuracy.
For SSR output, generally 0.5 to 3.0 seconds.
For Relay output, generally 15~40 seconds, because small value
will cause the frequent On-Off of mechanical switch and shorten
its service life. CtI is recommended to be 1/4 ~ 1/10 of
derivative time. When control under on-off control,Ctl use as
restart delay time affer off,for protect compressor application.
CHY is used for on-off control, if PV > SV, output turns off;
PV<SV-CHYS, output turns on.

"0" means 1℃or 1F, "0.0" means 0.1℃/F
Scb is used to make input shift to compensate the error
produced by sensor or input signal.
PV_after_compensation= PV_before_compensation + Scb.
Note:normally set it as 0
