Hi Fernando,
Is there a reason why +12v is connected to pin 9 on the fan circuit but not connected on the dosing circuit? Apart from that, both circuits seem identical

Hi!
You're right, the circuits are identical.
I never had problem of reset while the dosing pump was working so, I haven't the 12 V connected on pin 9 to make the circuit more simples.
Anyway you can connect it to prevent problem of reverse current.
Best regards.
