1.4.  In  the  event  of  an  over-temperature  alarm,  the  buzzer  beeps  continuously,  the 

ALM

  warning  light  is 

illuminated, and the heat-out is cut off. For an under-temperature alarm, the buzzer beeps continuously, and the 

ALM

 warning light flashes. If the over-temperature alarm is triggered by a change in the temperature setting 

value, the 

ALM

 warning light is illuminated, but the buzzer does not beep.

2. Auto-Tuning of PID

 

 
In the non-

set state, press the “SHIFT/AT” button for 6 seconds. The controller will enter the pre

-auto-tuning state, 

displaying the prompt “AT” in the upper window and “

OFF

” in the lower window. Users can use the “DEC” or 

“INC” button to choose between showing “

OFF

” or “

ON

”. When it displays the prompt “

ON

”, press the “SET” 

button,  and  the  controller  will  initiate  the  auto-

tuning  program.  The  “AT”  light  flashes  during  auto

-tuning,  and 

after the process concludes, the light stops flashing, and the parameter value is saved automatically. During the 
auto-

tuning process, pressing the “SHIFT/AT” button for another 6 seconds will stop the auto

-tuning program. 

If an over-temperature alarm occurs during auto-tuning, the buzzer remains silent, the 

ALM

 warning light is not 

illuminated,  and  the  heat-o

ut  is  cut  off.  The “SET”  button  becomes  invalid,  and  the  lower  window continuously 

displays the temperature set value. 
 
 
 

3. Internal Parameters Settings  

 

 
In the non-

set state, press the “

SET

” button for 3 seconds. The controller will display the password prompt “Lc”. 

Adjust the password to the  required value, then press the “

SET

” button again to enter the internal parameter 

setting  state.  If  you  press  the  “

SET

”  button  for  another  3  seconds,  it  will  return  to  the  running  state,  and  the 

setting value will be saved automatically.
