The Roadrunner Comfort controller is much more than a thermostat, but this still applies: How a Swamp Cooler Thermostat can make your home more comfortable

Evaporative cooler controller evolution
These old controllers are all still being used in many homes throughout the US southwest.
Unmarked Switches
Early evaporative cooler (EC) controllers used individual switches to turn on the water pump and the fan, with a third switch to select hi/lo fan speed.
The Rotary Knob
This rotary control offers simplified operation and labeling of switch positions (imagine that!). An improvement on separate switches, it uses a single knob to select fan and pump combinations.
SelectaStat II
An early thermostat for evaporative coolers, it uses existing high voltage wiring and a mechanical sensor to control the temperature. It works by turning on and off the cooler, so the air coming in goes back and forth between none and the coldest temperature possible.
Dial Cooler Controller
This digital thermostat uses individual relays to switch the pump and fan motors. It installs easily in place of rotary or toggle switch controls. But the tiny display can be hard to read. And it’s still just switching the system on and off.
MasterStat
This controller provides a larger display but requires the installation of a relay box, usually at the cooler itself, plus new low-voltage wiring between the cooler and the controller. It puts circuits and relays outdoors, likely shortening their lifetime. And it still switches everything on and off.
Digi-Stat
An improved version of the same thing. A remote thermostat with an outdoor weatherproof box looks more modern and has more buttons but still requires expensive installation. And it still switches everything on and off.
