I recognise this heater controller so I did a search ...
funny thing is if you do a search for "chinese heater controller manual" the first link is to a thread I posted on this very forum

Unfortunately I didn't post any instructions, but I was able to say:
"Initial stumbling block as no instructions and buttons in Chinese, but now I have sussed it out, this controller is actually pretty good. It has a temp sensor in so you can set a target for the heater to go to; It also has a clock and you can set 2 timers for it to go and and off (it is just a 24 hour clock, no days, so you cannot set different profiles for say weekdays and weekends)."
So it does work

Here is one with the buttons labelled in English which will help a bit I think ...
I did eventually find a manual for it but I have no idea where it is. If I come across it, I will post it up.
FWIW, I think most people ditch this controller and fit one of the graphical LCD Controllers instead.
