Demand (Tankless) Water Heater with Thermostatic Shower Control

You know, I started looking into this, and now I don't understand what
a "thermostatic" shower valve does. I thought it would adjust the
relative flow of the incoming hot and cold water supplies to provide
the desired temperature, regardless of the incoming temperatures. But
I have read a number of the manuals which state that if you adjust
your water heater temperature, you have to recalibrate the
"thermostatic" valve. In which case it doesn't seem very thermostatic
to me.
Are there any thermostatic shower mixing valves that will maintain the
set temperature given fluctuating hot water supply temperatures?
Cheers, Wayne
