I am looking for a solution to control automaticly the temperature in a room.

The setup will be done with a frequency drive with a 0-10v input control

The fan should be always running on 10hz on normal mode ( from 0 to 16 degrees )

once the temperature will go up over the 16 degrees the fan should need to be raise up every degree by 5Hz up to 50Hz at the maximum.

I have already search a lot of these situations but i can't find a solution, its the first time i needed analog in and oudputs 

 Thanks for the very fast answer, that program i wouldn't never found on my own.

I need to look what logos i still have at the shelf but these are maybe 0BA4 but i will look and come back if i find no 0BA6 more.

Is there also a possibility to change the set temperature in the display and change it from there with the buttons instead of changing the program ?

Here is a possible solution.
Up to 16 ° C for 10 Hz are given, then for every 1 ° C increase gradually 5Hz more.

Since you have not specified a logo, the hardware is set to 0BA6.

Nice program created there!

Just want to add something. Keep in mind when your PT100 sensor has a wirebreak, de measured value will decrease. In my opinion you want maximum rpm from the fan at that moment.

Offcourse, your process will decide what is the best solution.

Kind Regards
