Chiller PID
Posted: Friday 31 March 2017 10:44
Hello, I'm Roland and I'm new here.
Currently I have a ds18b20 for measuring the temperature of a chiller
and logging on a Raspberry Pi with Domoticz... This works great.
But now I would like to use this system to control the chiller.
I want to have the possibility to set different temperatures at several times.
My idea was to connect a solid state relay to one of the GPIOs of the Raspberry pi
to switch the compressor. So nothing really special on this...
But is there a PID construction for Domotics? Jumo has regulators which have
even an "auto tune" function to determine the system parameters. That would be great.
Can anyone help me to get a PID sample project just as simple to have
one temperature sensor to regulate the temperature in one area?
Thanks in advance!
