I am after a better specification of fuse than is on the board of a daikin split air conditioner
I would first check the electronics before replacing the fuse. Why is the fuse blown?
Beside that question:

Normally, control boards or electronics (without transformers or motors) are protectet with fast blowing fuses.
Here I would use (and it is not a big problem to use) a fast blowing fuse.

In the manual, the manufacturer only describes the fuse with 3.15 A only, and if you want to be really sure you have to contact the manufacturer.
