Hi,
This might be a bit on the basic side. But we are having some discussions of how to best control our heating process.
We have a small heating system with a quite heavy metallic piece being heated by circulating water. The water is heated with a electric heater.
Visualised: https://docs.google.com/drawings/d/1SIzLkL8jCQrVGOVacTOovkQCTvriJZHtjZSTb11QTAA/edit?usp=sharing
The question is; is it best to control the system based on the temperature before the metal piece or the temperature after the metal piece? I.e. TI 01 or TI 02?
The ones preferring controling the TI 01 say the control system will be much faster. The ones preferring controlling the TI 02 say the control system will be more rigid and less prone to becoming unstable.
Is there a clear "correct answer"?
Thank you!
