I would concur, especially with control devices that can turn on to heat. Although, a lot of more basic controllers only handle binary states for input. I'd argue that a calibrated (bang-bang with thermistor/thermocouple) on an analog control would be much easier to tune and easier to implement. That way, the hysteresis could be dynamically tuned out of the system with a constant input to stabilize losses. I did something similar to that with I experimented with a peltier heated 3d printing bed. I fried the first batch of peltiers since I wasn't aware they *HATED* binary states, and would die in a crack of the ceramic matrix. My next round was to implement "Using PWM to Generate an Analog Output" ( https://ww1.microchip.com/downloads/en/Appnotes/90003250A.pdf https://ww1.microchip.com/downloads/en/Appnotes/90003250A.pd... )
