Maintenance

Troubleshooting
If you encounter issues with your PAC-USWHS002-WF-2, refer to the following common problems and solutions:
Connectivity Issues
- Device Not Connecting to Wi-Fi:
- Ensure your Wi-Fi network is 2.4 GHz. While some dual-band routers work, the device primarily uses 2.4 GHz.
- Avoid special characters, such as apostrophes, in your Wi-Fi network (SSID) name. This has been identified as a common cause of connection failure.
- Try creating a guest network on your router with a simple SSID and password for the device.
- Reset the device: Use a paperclip to press and hold the reset button (typically a small hole near the lights) until the lights indicate a reset (e.g., two blinking blue lights for no internet, four rapid blue blinking lights for ready for install).
- Ensure your router is within range and providing a strong signal.
- App Not Responding / Slow Response:
- Verify your mobile device has a stable internet connection.
- Ensure the PAC-USWHS002-WF-2 is connected to the internet (indicated by specific light patterns, e.g., three blinking blue lights for operational and connected).
- Allow a few minutes for the device to come online and synchronize with the app after initial setup or power cycle.
- Check for updates to the kumo cloud app.
Installation Pin Requirement
- App Requires Installer Pin: Some setups may require an installer pin. A common default pin is 9999. If this does not work, contact your HVAC installer or Mitsubishi Electric support.
Compatibility
- Device Not Working with Indoor Unit: Confirm your indoor unit is compatible with the PAC-USWHS002-WF-2. Refer to the compatibility chart provided in the setup section or consult Mitsubishi Electric documentation.
- Cannot Use MA Remote Controller: An MA remote controller cannot be used simultaneously when an indoor unit is connected to both PAC-USWHS002-WF-2 and MHK1.
