i have H1 heater sign to duex.e2heat
so i need to sign new heater and then disable pin or how i could manage that?

If the Berd Air is your main print cooling fan, it's best to call it Fan 0 not Fan 9. Don't create heater 1. So I suggest you use the following:
M950 F0 C"duex.e2heat" Q100; Fan 0 is connected to duex.e2heat pin, PWM at 100Hz M106 P0 S1
The fan should appear on the dashboard automatically.
You should connect a flyback diode in parallel with the Berd Air motor, because the heater outputs on the Duet don't have built-in flyback diodes.

VCC is Vin (the one on the left in that diagram).
