How a Swamp Cooler Thermostat can make your home more comfortable

Ready for some history?

Evaporative cooler controller evolution

These are all still found in many homes throughout the US southwest.

Unmarked Switches

Early (and cost-conscious) 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 simplified operation and introduced labeling of switch positions (imagine that!). An improvement on separate switches, the rotary switch used a single knob to select fan and pump combinations.

SelectaStat II

An early thermostat for ECs, this simple device is still working in many homes today. It uses a high voltage mechanical sensor to control the temperature, similar to other thermostats of its day. And it uses existing wiring. But it works by turning on and off the cooler, so the air coming in goes back and forth between none and the lowest 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.


This controller provides a nicer design for your wall 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.


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.
