errore di calcolo

hi, for technical problems in line1 I have all the power of the electrical system. I saw that your total adds the 3 channels together and this gives me an error on the total because in line1, it is already all the power.

how do i configure the web to make sure that the 3 channels do not add to each other?

in my case:

linea1 total power 4.5 kw

linea2 air conditioning 3.5 kw

line 3 services 0.5 kw

but in line 1 they are already inserted, if I leave it as it is, I find total consumption for 8.5 kw

thank you
