Say goodbye to miserable cold spots as a constant flow of temperature-controlled air makes you forget all about air temperature. No more cycling between overheating and chilling! The Roadrunner Comfort uses your cooler smarter, so you can enjoy consistent comfort while you focus on more important things.

The Roadrunner Comfort is a next-generation thermostat for evaporative (swamp) coolers. Its remote sensor-enabled Active Temperature ControlTM actually controls the temperature of the air from your cooler, instead of just switching cold air on & off.

The color touchscreen and intuitive controls make it a pleasure to use. Save energy and water, be more sustainable. Fully guaranteed, customer service second to none.

Ready for some history?

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.
