Regulators and cascade regulators.

[Xadhoom]

i sometimes find myself wanting to control temperature in an area, and to do so i often use water or air pipes running trough it to cool or heat, when i do that i want more control over the temperature then just a simple on/off.

example, i want to heat up an area for farming, i then use water pipes running trough it to heat, if i'm able to better control the water temperature i would be able to heat it up faster when im starting up or other unexpected events happens, a cascade regulator would then lower the input water temp to easy stabilize the temperature.

a simple PI-regulator would do the trick imo.

You can simulate one with a bunch of thermo switches and creative wiring, look at the old hydrogen bubbler topic to get some ideas.
