Note 11. The SV can also be set directly during the normal operation mode. Press (^) or (v) key to switch

the display from process value (PV) to set value (SV). Press (^) or (v) key again to increase or decrease SV

by 1 degree.

① When AH1=AL1，relay is disabled,

② AH1＞AL1 is for absolute high alarm. See fig. 4.

③ AH1＜AL1 is for absolute low alarm. See fig. 5.

Auto-Tuning function (also called self tuning) can automatically optimize the PID parameters for the

system. The auto-tuning function will heat up the system then let it cool down. It will repeat several

times. Based on the response time of the system, the built-in artificial intelligence program will

calculate and set the PID parameters for the controller.

A）To activate auto-tuning, press and hold

auto-tuning is in progress. When "AT" stops blinking, the auto-tuning is finished. Now, newly calculated

PID parameters are set and are used for the system. Please note that Auto-tuning is only for PID control

mode (when "outy"is set at 1 or 2)
