Start fan and stop afer 15 minutes

Sorry being a newbie.

I have a humidity sensor and a switch that controls my central ventilation fan.
I want to do the following with PLEG:

  • start when > 80%
  • stop if <70%
  • stop <80% AND running for 15 minutes.

I tried some things, but it didn’t work.

Could I get some info please?
