User Manual for Della Mini-Split Air Conditioner (Wi-Fi Module)

Quick Start Guide

To begin using the smart features of your Della Mini-Split Air Conditioner, you must first install the DELLA+ app on your smartphone. Ensure your phone is connected to a 2.4GHz Wi-Fi network, as 5GHz networks are not supported. During installation, grant the app permissions for Storage, Location, and Camera to ensure proper functionality.

Wi-Fi Module Specifications

The Wi-Fi module operates on the 2.400 - 2.500GHz frequency band. It supports IEEE 802.11 b/g/n standards (channels 1-14) and security protocols including WEP, WPA, WPA2, and AES128. The module supports IPv4/IPv6/TCP/UDP/HTTPS/TLS/MulticastDNS protocols.

Adding Device to App

There are two modes for adding your air conditioner to the app:

• EZ Mode (Quick Connection): Power on the unit. In the app, select 'Add device'. Reset the Wi-Fi module by pressing the 'DISPLAY' button on the remote controller 6 times (or use the reset button on the unit) until 'CF' appears on the indoor display. Follow the app prompts to complete the connection.
• AP Mode: If EZ mode fails, use AP mode. Reset the Wi-Fi module until 'AP' appears on the indoor display. In the app, select 'AP Mode'. Connect your phone to the 'SmartLife-****' Wi-Fi network in your phone's settings, then return to the app to finish the setup.

Air Conditioner Control

The app provides two control interfaces (Control Form 1 and Control Form 2) depending on the firmware. Both allow you to:

• Power: Turn the unit ON/OFF.
• Mode: Select between Feel, Cool, Heat, Dry, and Fan modes.
• Fan Speed: Adjust speed (High, Med, Low, Auto). Note that fan speed may be restricted in Dry mode.
• Temperature: Increase or decrease the set temperature.
• Air Flow: Adjust swing directions (Up-Down, Left-Right).

Advanced Functions

Depending on your specific model, the 'More' menu provides access to additional features:

• GEN Mode: Allows you to limit the current levels (30%, 50%, 80%) to save energy.
• Electricity Monitoring: View daily, monthly, or yearly energy consumption statistics.
• Self-diagnosis: Automatically checks the system and displays error codes (e.g., E0 for communication failure).
• Anti-Mildew: Dries the unit after turning it off to prevent mold.
• Health: Activates the antibacterial ionizer (if equipped).
• Reservation: Set specific times for the unit to reach desired settings.

Troubleshooting

If you encounter issues, check the following:

• Configuration Failure: Verify Wi-Fi password, ensure the unit is in configuration status ('CF' or 'AP'), and check for firewall restrictions.
• Control Issues: If the app shows 'Identification failed', the unit may have been reset. Reconnect the Wi-Fi to restore permissions.
• Device Offline: Ensure the unit has power, the router is working, and the signal strength is sufficient.
