Happy January, and welcome to 2019! More importantly, welcome to the new MRCOOL Smart Controller, the best wireless control system for any ductless mini-split heat pump system ever made (so far!).

What’s a MRCOOL Smart Controller?

The MRCOOL Smart Controller is our new wireless control system that integrates with your smartphone and/or other smart-home devices. Which ones? Right now the Smart Controller is compatible with both Alexa and Google Assistant.

Yeah, sure, all that compatibility is great, but what does this thing do?

Well, I’m glad you asked.

Amazing MRCOOL Smart Controller Kit Features!

  • Global Control – Control your MRCOOL air conditioner or heat pump via your smartphone from anywhere in the world.
  • Weekly Scheduling – Powerful 7 day scheduling functionality helps you schedule your air comfort as per desired settings and time.
  • Filter Maintenance Reminder – Because changing the filter is important, and you don’t need to keep forgetting.
  • Geo Fencing – Automatically turn your ductless unit on before you arrive and switch the system off automatically after you have left the premises.
  • Zone Control  – Create dedicated air comfort zones. Single touch control for all home systems by creating zones.
  • Usage Statistics – Keep track of your heating or cooling usage to control your electricity costs. Save energy, save money, live free, etc. 
  • Timeline of Actions – Check a complete timeline of actions of your AC. Check who is using your AC, what settings are being used and when.

Awesome, right?

Who wouldn’t want all those tools to get the very most out of their brand new MRCOOL ductless mini-split heat pump system? And we use that term generally, because the Smart Controller will work seamlessly with all current generation ductless mini-splits that we make. To learn more, but a new MRCOOL unit that includes the Smart Controller or buy a new Smart Controller kit from your favorite dealer!

  1. My only Wifi access is a Fair signal from a PublicWifiRouter which of course I cannot alter. My computer and phone usually can lock on to that Wifi signal, but it looks like MrCool cannot (because of its fixed location in the center of my house). I installed the MrCoolApp on my phone. My phone ‘grabbed’ the MrCool HVAC signal fine. My phone has both LTE and Wifi connections. My phone can provide a WifiHotspot (via LTE) and can also connect to Bluetooth devices. The one and only thing I cannot provide is a DIRECT connection between MrCool and the PublicWifiiRouter. Is there any hope in such a situation? THANKS.

    1. P.S. I have no interest at all in Global Control or Geo Fencing. I hope only for Usage Statistics, Weekly Scheduling, and maybe Timeline. ~ I LOVE my DIY MrCool! It cut my cooling bills in half last summer (with increased comfort) and keeps this increasingly-old geezer from needing to build a fire in the woodstove except in the coldest winter weather. (For decades I have tried to avoid fossil fuel use. I would prefer to heat ONLY with wood, as I have for decades, but MrCool has given me an energy-efficient compromise for my Last Chapter.)

      1. Thanks. I sent an email a week or so ago and received a notice that it was refereed to the app developer but as of yet no response. I just called and left a voice message with tech support.

  2. I have the Mr Cool smart controller application installed on my smartphone and it works very well. I would like to have the same application on my desktop computer (Linux). My mini-split is 160 miles away and I would like to check during the day without having to bring it up on my phone.

    1. I second Ken Morgan’s request! I would like to have a desktop version of the app, as well–either Linux or Windows, but Java would cover all the options (hint hint…. ;-).

  3. I’m having trouble my Mr kool app because I don’t have a QR code STICKER. I INSTALLED IT AND IT WORKS GREAT. Is there a way to get the sticker?

    1. You shouldn’t need a QR code sticker to connect the Smart HVAC app on your phone. The system should connect to the Smart HVAC app via the Smart Controller USB. Once you create an account on the app, and the USB is installed in the unit, you can tap the + button to start setting up your system. When you go to your phone’s Wi-Fi settings, connect your phone to the Smart Controller Wi-Fi, which should appear as SmartHVAC_B103_xxxxxx. Once you’re connected, go back to the Smart HVAC app, connect to your Wi-Fi network from the list that pops up, and press the connect button when you’ve entered the password. After this, connection should be complete. If you run into any issues during this process, please give us a call at 270-366-0457.

  4. Hi, I’ve been trying to get my smart controller to work on our Mr Cool mini split since last summer. I’ve called support several times and no one answers or returns messages. Not sure what to do. I’m a tech nerd and usually don’t have trouble getting connected devices setup but it simply won’t work with the instructions I have. Mr Cool support was so, so awesome before last summer. Anytime I had a question before or after purchase, the phone was answered promptly and someone knowledgeable was able to help. I’m a little scared not being able to get in touch with anyone for months now. Any info/support would be great.

  5. If I set mine to say 82 F on the app, it just keeps blowing cold and the room temp is now 77 F.
    Is it normal to just keep blowing 82 F ‘cold’ air and never stop when it reaches the set temp in the room?
    I have tried auto, and Comfy. Still just keeps chilling.
    Is there a thermostat reset or anything I have overlooked?

  6. I know you can shut off the beep temporarily, but I really need to turn this feature off for good. Every time it beeps, my dog freaks out and gets very scared. Might as well be fireworks to her. I looked for a way to do this through the app. Seems like it should be a simple preference in the settings.

  7. Yeah same problem. Assuming the thermostat uses the unit/room temp rather than the app/phone temp but the unit keeps cooling way past the setpoint. Ideally it would cycle off and on based on setpoint +/- deadband. Also, a way to turn off led from app?

    All-in-all, a truly kick ass system. Love the DIY setup, I honestly do see me going back to the “old school” way. Keep up the good work!
