  1. Make sure that your Mr. Cool unit is installed correctly and is running properly.
  2. Check the box of your Mr. Cool unit and look for the Mr. Cool Smart Kit inside. The Smart Kit is a small box that contains several QR code stickers, a Smart Kit USB adapter, and your user manual.
  3. Remove the cap from the Smart Kit USB adapter.
  4. Open the front panel of your Mr. Cool unit. You can open the front panel of most units by pulling it upward.
  5. Look for the USB port on the Mr. Cool unit. It is usually located behind the front panel, away from the mechanical parts of the unit. It will have an electrical wire coming from it.
  6. Insert the Smart Kit USB adapter into the USB port on your Mr. Cool unit. You can optionally place one of the QR code stickers on the surface of your Mr. Cool unit before you close the front panel. Alternatively, you can place the sticker in a location where you can easily find the QR code in case you need to reconnect your Mr. Cool to the internet.

Getting Into The Wi-Fi Setting Mode

  1. Turn off your Mr. Cool unit and wait for two minutes. Locate the LED button on the remote while you’re waiting.
  2. Turn your unit back on. Once it is completely back on, press the LED button on your Mr. Cool remote control seven times. The letters “AP” would light up on the front cover of your Mr. Cool unit. The “AP” indicates that the unit has entered the Wi-Fi setting mode.

Connecting To The Internet

  1. Open the Mr. Cool app on your phone.
  2. Tap on the “+ Add Device” to add your Mr. Cool unit. Your phone might ask for your permission to allow the Mr. Cool app to access the camera. Allow the app to gain access to the camera before you proceed to the next step. There will be a QR code scanning interface that will appear on the app after you agree to provide the app access to the camera on your phone.
  3. Scan the QR code on any of the stickers from the Smart Kit. The app will then ask you to select a Wi-Fi hot spot. If you have several Wi-Fi hot spots inside your house, select one that is closest to your Mr. Cool unit. Keep in mind that some routers can provide two or even three Wi-Fi hot spots at the same time—one running on the 2.4 GHz bandwidth and the other running on the 5.0 GHz bandwidth. The 2.4 GHz connection is best for your Mr. Cool unit.
  4. Enter the password for the Wi-Fi hotspot that you selected. Passwords for Wi-Fi hotspots are case-sensitive.
  5. After your Mr. Cool unit is successfully connected to the internet through your Wi-Fi router, it will appear on the list of devices on your Mr. Cool app.
  6. Tap on the device name of your Mr. Cool unit, and you can access it through the app on your phone. The app will allow you to access and control your heating and cooling anywhere you are as long as you have access to the internet.
