Some things confuse me:

For information, I changed the position of terminal C of the two-speed switch on L1 of the LOGO Power.

If I interpret your circuit diagram correctly, you have 230 VAC on connection "C" of the switch. Connections "1" and "2" of the switch are connected to inputs I1 and I2 of the LOGO. You have a 12/24 RCE (6ED1052-1MD08-0BA1). However, these inputs cannot handle 230 VAC, max. 28.8 VDC.

This could destroy the LOGO!.

I would like to add a command for a circuit breaker, once the machine door is opened the fan stops.once the door is closed the program resumes its normal course.

What do you mean by a circuit breaker?
Or mean you a normal switch (NO or NC)?

I would also like to add a two speed switch.To be able to turn the fan once outside the program temperature ranges.

What function should the switch have exactly in which position? He has 3 positions (1-0-2).

...,  once the machine door is opened the fan stops.once the door is closed the program resumes its normal course.

This is a NO switch.

When the door is closed:
Is the switch open?
Or is the switch closed?

Regarding the speed switch.1=25hertz, 0=0hertz, 2=50hertz.

And what is the condition for selecting whether the analog value to the AQ comes from the thresholds or from the speed switch?
