Hi,
Is there any version of firmware for hot air with digital control of fan engine?

I receive this error when i try to download the firmware:
Выбранное вложение отсутсвует.
The selected attachment is missing.

?

What is happening with the fw files ? Выбранное вложение отсутсвует. The selected attachment is missing....

Firmware are missing only the 900°С is working.
Why don't you add another switch combination to set max working temp.

What firmware can i use on this diagram for solider and fan. The firmware in the link makes only noise on the buzer i don't know why.

Вот то что, у меня получилось. не фонтан конечно но всё же, переднюю панель придумаете сами так как детали разные.
Также прикрепил файл прошивки и схемы БЕЗ ДИОДА!!!
