When conventional substations with PID-regulators work with the principle "correct the error", the enabler^TM is "designed for correctness" and will do the right thing in the first place.

The PID-regulator then is error-correcting or "trial-and-error"-based. A reason for why PID-regulators are so popular is that it is a general method which can be applied even though you do not know so much about the process you control.

The enabler^TM is not based on error correction, but on supply of power based on demand. It is built on the fact that we know the process. It is not a general method - it is knowledge based. In practice measurement of flow and inlet temperature and specific heat capacity of water.

This is not error correction. We want to designate the term "control" as opposed to "regulation" in the PID case.

The result is a stable control which is fast. You do not need to wait for result (outlet temperature measurement).

There is no feedback - which means that this system cannot become unstable. And there are no difficult parameters to adjust.

As a bonus the transferred power is under control. Which means useful measurements and possibility to implement for example power-loan functions (decrease heating system power during high hot water demands).
