Does the firmware work on T-962 with 3 buttons?

will the FW work on the oven with just 3 buttons?
there are just few photos, all with 5 buttons

I suppose it is not the same as black 2.0 variant, which is quite different as stated in other tickets

Has anyone managed to get this version of the reflow oven updated with the firmware ?
