basic Thermostat

Hey guys, Im quiet new to labview and im trying to do a simple project for myself to try to make up a basic thermostat that will keep the temp within the limits automatically when certains temps are met on the upper and lower limits. I can get as far as doing a case structure but i have a hard time understanding how to wire it back so that  it will add a constant of 5 if its too low or take away a constant of 5 if its too high. If there is anything else i should include feel free to ask. Thank you!

We cannot see what you are doing wrong unless you show us your VI. I don't think a "case structure" is sufficient, you might not even need one. 😄 To maintain values across iterations, a shift register is typically a good idea. Do you use one? What are the units of the "5" constant?


(Is this just a software simulation or do you interface to a real temperature sensor and heating system?)

Sorry I thought I added the VI😅. Here it is. Im very new to labview. Im just using 5 as away to bring the temp down or up to keep the thermostat within the threshold. Its only a simulation that im doing.

Sorry, I don't have LabVIEW 2021 here. Can do do a "save for previous".

Hey, just put in the 20.0 version there. Is that ok or do you need an earlier version?

This is still LabVIEW 2021. You need to attach the down-converted version, typically saved in a nearby folder.
