Lock Function Setting: LoC1, LoC2, or OFF. LoC1 mode will lock all settings, LoC2 locks everything
except the setpoint value, and OFF will not lock any settings. Press
and keys simultaneously, to
release the lock status.

OUT: The Output value adjustment and display in manual tuning control. (Not available in ON/OFF or
Auto-tuning control).

2. Regulation Mode: Control parameters Settings
LED Ex
p
lanation Default
AT (Auto-Tuning): ON or OFF, when set ON, the execution of the auto-tuning function in PID control
mode is automatically started. (Only available when PID control is selected in initial settings)
OFF
P (Proportional Band in PID control): Sets P value. 47.6
I (Integral Time in PID control): Sets I value. 260
D (Derivative Time in PID control): Sets D value. 41
PdoF: Offset output when P or PD control function is on. PID in initial settings is selected and the value
of Ki (Integral Time in regulation mode) is equal to zero.
0
ioF: Default value of integral volume when PID control is ON and the Ki (Integral Time in regulation
mode) is not equal to zero. AT function can automatically set this parameter when PID control is active
and Ki≠0.
0
HtS (Heating Hysteresis): Available only in ON/OFF control. Sets the value the heating hysteresis. 0
CtS (Cooling Hysteresis): Available only in ON/OFF control. Sets the value the cooling hysteresis. 0
HtPd: PID heating control cycle setting. Only available when a PID control is selected in the initial
settings.
ClPd: PID cooling control cycle setting. Only available when a PID control is selected in the initial
settings.
Output Selection:
Voltage: 4 sec.
Relay : 20 sec.
TPoF: Regulates the temperature deviation value. 0
CrHi: Regulates the 20 mA output deviation value. 0
CrLo: Regulates the 4 mA output deviation value. 0
HtS (Heating Hysteresis): Available only in ON/OFF control. Sets the value the heating hysteresis. 0
