What's new in v5.4.5

This release brings the most innovative features for users who own a MRCOOL Multi Zone Mini Split System. Since these systems can only operate in either heating or cooling mode at one time. This limitation can lead to Mode Conflict situations when one indoor unit is switched to heat mode while others are operating in cool mode or vice versa. This release will help you solve Mode Conflict issues permanently resulting in smooth operation of your multi zone mini split systems.

How to install MRCOOL SmartHVAC on Android 5.0+

You'll need about 145.3 MB of free space.

  1. Download the APK — tap Download APK above (72.7 MB). Chrome shows “File might be harmful” for every APK file; choose Download anyway only if you trust this file.
  2. Open the file — tap the download notification, or open Files › Downloads and tap com-smarthvac-83-68096614-8b6235ec45e8d9a52ebe589a07fa0b05.apk.
  3. Allow the install (first time only) — Android 8 and later asks for permission the first time an app opens an APK: tap Settings in the prompt, turn on Allow from this source, then go back. Manual path: Settings › Apps › Special app access › Install unknown apps (on Samsung: Settings › Apps › ⋮ › Special access). On Android 7 and older: Settings › Security › Unknown sources.
  4. Check the file (optional) — the MD5 of the downloaded file should be 8b6235ec45e8d9a52ebe589a07fa0b05. If it differs, the file is damaged or was changed: delete it and download again.
  5. Tap Install — Android asks “Do you want to install this app?”. If Google Play Protect shows a warning, read it before you continue: the source store rated this file Trusted, but only install apps from sources you trust. If an earlier version is installed, this one only installs as an update when it is signed with the same certificate (SHA-1 shown above).
  6. Open MRCOOL SmartHVAC — tap Open on the install screen, or find it in your app drawer.
Common install problems
  • “App not installed” — a version signed with a different certificate, or a newer version, is already installed (Android doesn't allow downgrades). Uninstall it first; back up your data, because uninstalling deletes it.
  • “There was a problem parsing the package” — the file is incomplete, or your Android is too old (this version needs Android 5.0+). Download it again, or pick an older version.
  • “App not compatible with your device” — this build contains native code for x86 32-bit, x86 64-bit, ARM 32-bit, ARM 64-bit only. Devices with other processors can't install it.
  • Blocked by Play Protect — Play Protect checks apps from outside the Play Store. Only continue if you trust the source.
