I researched all of the available thermostats and controllers for swamp coolers and this particular model seemed to be the best solution for my "new" 1970s home. Installation was a bit tricky because the unit is pretty bulky and needless to say, there are a lot of wires coming into that single gang electrical box and this adds even more wires in addition to the included wire nuts. The electrical connections were easy to make but shoving it all back in the box takes some careful arrangement of wires. This thermostat works great, even though mine is mounted in a less than ideal location directly below the swamp cooler vents. I find that I can thermostatically control the cooler but have to set the temperature lower than what I want the room temperature to average. It favors low fan speed for economy, only rarely running in high speed for short periods of time. We are now comfortable and saving a lot of water and energy since even on 90+ degree days so far this year, the swamp cooler only cycles on for a few minutes at a time several times per hour, and we now just leave it on round-the-clock for comfort and convenience. My next task is to add adjustable "Up Vents" to each bedroom and the kitchen so I can control air flow to each room and keep my windows closed and locked.

Note that there is an automatic 2 minute pre-wetting of the pads before the fan kicks on but this only seems to occur when the swamp cooler is started up after being shut off for a period, and not when cycling on and off under thermostatic control. The pre-wet delay can be overridden too. The thermostat has a timer which allows for the swamp cooler to be either turned on or off 2, 4, or 8 hours in the future. This has little value for me, but I would have paid more to have true programability based on a weekly/daily clock.

One piece of advice I was given was to double check that the needed common white wire is present in the electrical box. The common wire is not connected to the typical rotary switch which I was replacing, but fortunately it was present in the electrical box, so I was able to easily connect it to my new thermostat.

This thing is nice! As a life-long AC user, maybe I can live with a swamp cooler after all!

I decided to automate our Swamp Cooler(s) and found the Dial 7625 on Amazon at a good price.

Even though the unit is almost beneath the cooler outlets and therefore doesn't accurately control the temperature, it is still valuable as it pre-wets the cooling pads and detects if it needs to go on full or half power to cool.

It is easy to select "cool" instead of "auto" once the unit has done an initial cool down and in fact "cool' can be selected, then the timer set to run for an additional two hours. Although not fully automated, this process works well for us and is easier than clicking the previous manual switches. Nice product that fully met my expectations.
