Hi Bing,
I was thinking of doing a similar project for my Degree in Mechatronics.
Could you send any info to me,as i was interested inhow your project turned out.
Do you need a motor to get a fan to work to turn on?
or is it better to use a heater to warm up the room?
Any info i would appricate it

If you are close to a degree in mechatronics, you should be able to answer your questions by yourself...

Hello Henrik, and all looking for a on/off temperature controller,
Here is a VI I created based off of Henrik's hysteresis-set point controller. I modified it so that the set point is the average of Ton and Toff, and so that the hysteresis is the difference between Ton and Toff divided by 2.
I am planning to read the temperature in from a thermocouple, and will output an on/off signal to a relay using the logic from the heater on/off.
I hope this helps any other people who are looking for this type of a controller.
Also, I would be interested to see Henrik's solution to this type of on/off controller (rather than hysteresis/set point).
Best,
Thomas

OMG that code is more than 8 years old.... I can't remember how many new PC's I got inbetween 😄
Maybe I find the time to look for that old vi... if I find that old harddrive ..
Q&D LV-Forum help vis rest on my local drive....

I know this thread is a few months old but is there chance you can post your example in 2017 version?
Thank you in advance

made a picture ... the main control scheme is drawn in a minute ... this one is for cooling .. homework would be to change it to a heater 😄

Good Morning Henrik,
Yes, your block diagram is easy to follow. I was referring to Thomas' Heaters Control.vi , Although I should be able to use your example, it would be nice to see what other ideas are out there. Thomas' vi is from a 2018 version, I'm using 2017. Even a screenshot would do.
Regards,
Sandro

Good Morning
May I know why we have subtract the error with the hysteresis band and also what is the conversion done in the expression node why is it done
