I wonder if you could try adjusting the heating element shut off - see point 7 on page 3 of the manual?
Incubator Chinese No name JN 48 Manual
If adjusting the settings above fails, and you never adjusted the factory settings initially yet the unit overheated out of the box then it's a faulty unit and I would personally return it demanding a new one.
These units (as you correctly say) are supposed to be factory set to around the basic correct temps for egg incubation and only minor adjustments should ever be necessary. Once you start chasing big temp changes either way up or down it's no good. In my case, when my unit eventually died I had to keep winding the temp up to keep it stable but in the end the heater element just packed it in...
BTW, I recommend placing these incubators into a separate insulated box or insulating it in some way in order to help the machine not work so hard to maintain temps and this will prolong the life of the unit.
I have just purchased another cheap Chinese made incubator a JN-448 on eBay here and I'm ensuring I use extra insulation around the unit this time! Two nights ago I had a 64% hatch rate of quail eggs and the temps are remaining very stable I'm hoping to get more life out of this unit by looking after it.
