Hehe, you just need to learn Chinglish.
I am looking at getting one of the TA4 PIDs because my Auber PID took a dump for no known reason.
Reading the manual, it appears that you are to hold down the "<</AT" button for 3 seconds or more to enter auto-tune mode.
Yes, assuming you are using an SSR to control power to your element, you should set the module to SSR output.
You may want to take a look at other threads involving the Auber PIDs and copy those settings for the PID portion. Otherwise, the factory defaults will probably work fine.
Let me know how it goes.
There are a terrible lot of lies going around the world, and the worst of it is half of them are true.
