  Operation discription 

● 

Set Value Setting:

In basal display status, we can set setpoint (SV) by pressing 

、 、

  or 

.Press 

    to decrease the value , Press 

  to increase the value, and 

  to move to the 

digit expected to modify. Keep pressing 

  or 

, the speed of decreasing or 

inscreasing value get quick.   

● 

Parameter Setting:

In basal display status, press

  and hold for about    2 seconds can access Field 

Parameter Table. Pressing 

can go to the next parameter; pressing 

  or 

can modify a parameter. The equipment will escape auomatically from the parameter 
table if no key is pressed within 30 seconds. 

● 

Intelligence control and auto tuning

When At control method is chosen, the control parameters can be obtained by 
running auto-tuning. At the first time of running auto-tuning, in basic display status, 
“At” will flash at lower display window and the equipment executes on-off control. 
After 2 to 3 cycles of on-off action, the equipment will obtain the values of PID control 
parameters. If you want to escape from auto tuning status, press 

  and hold for 

about 2 seconds until the "At" flash stops. Depending on the system, the time of auto 
tuning can be several seconds to several hours. After the auto tuning finishes, the 
parameter “At” automatically changes to “OFF”, If user wants to run auto tuning 
again, setting parameter “At” to “on”.   

Note 1: 

Before running auto-tuning, setpoint should be set to an often-used value or middle
