Generic setpoint control with appropriate units rather than temperature

[Rowan Jones]

Is your feature request related to a problem? Please describe.
I need to control a dehumidifier instead of a heater. Everything else except the units is the same. Indeed, we can look at this as an abstract control problem rather than 'thermostat'. We have the setpoint, and the current value. Whether it's temperature or humidity or water level is irrelevant to the control loop. It only matters when displaying the values.

Describe the solution you'd like
Change configuration to setpoint min/max and desired units.

Describe alternatives you've considered
Ignore that temperature is really 'some other controlled parameter'.

Hi, the "temperature" is inherited from the generic thermostat. Changing this means rewriting the full integration.
