Best Evaporative Swamp Cooler Thermostats 2019
Swamp coolers have many positives about them from low-cost electricity prices to adding moisture in a home.
 
Most homes that have a swamp cooler use a manual evaporative cooler switch to control their swamp cooler. A manual switch simply turns a unit on or off along with other features such as fan only manually.

Manual switches work fine for many people but there are also set-it-and-forget options like a thermostat controls a regular air-conditioning unit.
 
Installing a thermostat that controls a cooler on its own with a set temperature is easy to do and common.
 
The wiring color codes are usually the same and even though it helps to be a handy person, installing one is not that difficult.
 
Below is some of our favorite swamp cooler thermostat controls.

    Wasn’t sure if I needed to buy relays or something other than the thermostat controller. I have the controller and will attempt this install later today. I will let you know how it turns out. (Given the E.M.T.’s fibrulator works)!

    Are there any week-day programmable thermostat that work with evaporative coolers?
    I have been told they do exist but never get an answer on which ones.
    I found the emerson sensi to say it has more compatibility than ever…but not sure if it will work with evaporative (ducted) air conditioners.

    If you have any suggestion it is kindly appreciated.

      I connected a Honeywell day of the week controller in series with my low voltage White-Rogers thermostat.
