MRCOOL Comfy Mode: Advanced Temperature Control

One of the standout features of the MRCOOL Smart Controller is the Comfy mode, which offers a sophisticated level of temperature control for your ductless mini-split heat pump.

Setting up Comfy Mode

To use the Comfy mode, you’ll need the following:

  1. An MRCOOL Ductless Mini-Split System
  2. An MRCOOL WiFi Dongle
  3. A stable internet connection

Here’s how to set up the Comfy mode using the MRCOOL app:

  1. Open the MRCOOL app on your phone or tablet and tap on the AC icon. Choose to power “On” the AC for which you want to set the “Comfy” mode.
  2. Set the AC in “Cool” mode and set the temperature to 67 degrees Fahrenheit. This is 1 degree Fahrenheit cooler than the Comfy range of choice.
  3. Tap on “eSaver” in the navigation bar on the app.
  4. Hit “My Rules” in the app.
  5. Tap on the “+” icon to add a new rule.
  6. Select “Comfy” as the trigger.
  7. Set the temperature range for Comfy, for example, between 68-70 degrees Fahrenheit.
  8. Save the rule.

How Comfy Mode Works

The Comfy mode triggers “on” when the room temperature is 1 degree higher or 1 degree lower than the optimal temperature range set by the user. For example, if you choose the temperature range for Comfy to be between 68-70 degrees Fahrenheit, the AC will trigger “on” if the room temperature falls below 68 degrees Fahrenheit or reaches a temperature higher than 70 degrees Fahrenheit. In a matter of minutes, the temperature will increase or decrease in the room through the MRCOOL mini-split heating and cooling system.

This advanced feature provides homeowners with greater flexibility and control over their MRCOOL ductless mini-split heat pump, allowing them to automatically and simply manage their heating and cooling while maintaining their ideal level of comfort and reducing monthly energy costs.
