Electric help needed

Here is schematic diagram of Gib thermostat hygrostat. What I want to do, is connect fan ventilate my grow room when temperature raise over 25C/77F and connect my ultra sonic humidifier on when humidity drops under 50%. Unlucky for me, I dont understand this schematic. Wich line goes where?

Please help slow thinking old pot head. We use 230V AC in here.

Here is what I got but someone else will chime in before you do anything okay! 6 = Humidifier - 7 = Dehumidifier - 5 = dual 230v/or24v - 4 = dedicated 230v - 8 = 24v dedicated. I think, hope I helped a little. Peace.

Thank you very much, Moondance. But.. there is L and N line in the fan and in the humidifier. Dont I have to connect em both to box? Wich number? Or do I have to pull N lines for fan and humidifier from wall plug?

Like this: Fan L to the number 3 and fan N from the wall plug, humidifier L to number 6 and humidifier N from wall plug?

Electrician work isnt for me, but in here (damn near russia), we pot heads are popular as child molesters. So I cant ask professional help. I have to be electrician, constructor worker, plumber and ventilation specialist.

Okay I understand completly, you want to look in this section and ask a question in any of the cobb building threads those guys can fabricate anything electrical they will take care of you. https://www.rollitup.org/f/grow-room-design-setup.66/
