Hi everyone !
I am working on a project, and i have some problem ... I want to set a numeric input state to disable or enable with a switch but hold the value . Could someone help me?The saved value is stored on a file and load from there with the load/save button .... The method i want to use is working with the switch ui element ,but not with the input .

You have a big flow there.I'm not sure I understand what tthe issue is.
Is it the fact that the temperature starts at -20, but if you prss the inject node toset it to 20 and then when you hit the `auto save` button it goes back to -20?

Yes , if i hit the save and then the load button it goes back to -20 ,it works , if i delete this part : 
In my project there will be 2 mode (auto and a manual) controlling tab. I want to save the input data and then load it back

If you just disconnect the wires to the `Auto_en_t` nodes it seems to work fine.

No , it not works for me. The Temperature input node will not be enabled at all.
I updated the code , and the topic to be clear.

Ok, I figured out what is happening and it all revolves around a line in the description of the `numeric` ui node:
> Any input messages will be converted to a number, the **min** value will be used if conversion fails, and it will update the user interface. If the value changes, it will also be passed to the output.
Now go and add a debug node to the output of every node that sends something to your `Temperature` ui node . What do you see?
