When setting control is in pause control and temperature is controlled at the setting value before the stop, by re-selecting 
the start status, the program will start running from the step where the program was paused and carry out the remaining 
part.

Note: When any settings or changes of the program parameters are made, please save the settings/changes to the
controller by opting for parameter SAVE. Otherwise, the settings/changes will be reset upon power-off.

How to 

SAVE:

Select

 in  the  menu,  then  press  the 

  keys  and  select 

 to  complete  saving.   The 

 key is displayed only when any settings/changes are made. 

Using RS485 communicatiion writing value 1 to address 1129H, the parameters will be saved.

Remote Mode: 

Input of setting value can be dynamic, an analog value (voltage or current) can be converted into a dynamic input

value. Two methods can be used for the conversion: positive slope or negative slope, they are depicted as follows:
a

  Positive slope Remote setting: Display of Remote analog input is in positive proportion with setting input, e.g.: Remote input

type is selected as 1~5 V analog voltage, Remote higher limit of input is set as 5000, Remote lower limit of input is 1000, 
decimal display is set as 0; when Remote input is 5V, the screen shows 5000; when Remote input is 2V, the screen show 
2000; this is the dynamic setting of the screen display. (Dynamic setting value =(Remote higher limit of input – Remote lower 
limit of input)*(Remote input value - lower limit of Remote input)/( higher limit of Remote input - lower limit of Remote input)+ 
Remote lower limit of input) 

b

  Negative Slope Remote setting: Display of Remote analog input is in negative proportion with setting input, e.g.: Remote 

input type is selected as 1~5 V analog voltage, Remote higher limit of input is set as 5000, Remote lower limit of input is 1000, 
decimal display is set as 0; when Remote input is 5V, the screen shows 1000; when Remote input is 2V, the screen show 
4000; this is the dynamic setting of the screen display. (Dynamic setting value =(Remote higher limit of input – Remote lower
