dunno mate can,t read chinese.sounds right to me. are terminals 5 and 6 for elv dc (12 - 24V), or is that the rating of the switch?
maybe engineer 54 can help.
L and N in on 3 & 4 . sensor on 7 & 8. then 1 & 2 switch. L to 1 and switched L to heater on 2. N direct to heater. do not wire N to terminal 2 or it will go bang.
