Life Saver
On eBay the original part can range from $259-689. Your price was so reasonable. There is an orange wire hanging and the manual did not explain what it was for. That is my only suggestion for correction. It works fine without it. Thanks for the retrofit solution.

Fixed my aging MasterCool unit
Easy to install and allowed me to fix my aging AdobeAir cooler that the electronics went bad on. Otherwise, the cooler is still in decent shape so this saved me from having to replace the whole cooler.

New controller
I just mounted it directly to the new cooler since it’s exterior now. My plugs didn’t have an extra drain outlet either but I only need that once a year. Thermostat is a little sensitive with it going between low and high a lot sometimes. Other than that works great. New thermostat is way nicer than old one.

115 VOLT COOLER CONTROL & THERMOSTAT RETROFIT KIT FOR MASTERCOOL PLUS OR CONTRACTORS SERIES
It’s working great. I purchased the control & thermostat kit last year That this one replaced. The one I purchased last year never worked right. This one works perfectly and was very easy to install. Delivery was very fast.

Awesome upgrade
I was able to follow the wiring diagram and called in for one question. I live in Colorado and I called around to see if anyone was familiar with the Adobe Mastercool systems. No luck. I took to the task myself and was able to figure it out. I have basic wiring knowledge. Ensured the breaker was off and went to work. Very nice unit, I think it saved me $3-3.5K by not having to replace the cooler. Thank you!

Could not find original replacement
Replaced my original contractor series with this new system, installation was a breeze, chose to use the dump pump option , working great. Would highly recommend this replacement product.

I guess this is a "one size fits all" fix. my problem was there wasn't adequate room to install the box in the vertical position so I mounted it horizontally on the top of myHPC640E cooler, sealing the perimeter and hoping the cover is actually wate
Had to call the "Salesman" as I couldn't ascertain the unit was acceptable in the horizontal position-otherwise no hitches.

Cooler Kit
It all appears to work well. I installed it on July 24, 2019 and I appreciated your phone call to clear up a non existent problem

Controller/thermostat kit for MasterCool plus
So far so good... This unit is working excellently... Hopefully it will last many years.... I would recommend it highly... Contractors should be made aware of its existence...

110 volt Evap Control Box
Worked out great. This item is a newer design to my old box, so some rewiring was required. I'm not an electrician, just your average DYI homeowner. With average intelligence and following the wiring diagram, this was a simple job.
