Modern water heaters are no longer just containers with heating elements, but have become fully-fledged elements of a smart home system. Model Ariston Velis Evo 50 Equipped with an advanced digital interface that allows you to control the temperature and operating modes remotely. However, to take full advantage of remote control, you need to properly integrate the device into your home network.
The setup process may seem complicated at first glance, but if you follow the steps, it only takes a few minutes. The key point The key is having a stable signal and a compatible mobile device. In this article, we'll cover each step in detail, from checking the package contents to troubleshooting common connection issues.
Before proceeding with the software, make sure your router operates in the 2.4 GHz band, as many IoT devices do not support the 5 GHz frequency. It's also important that your smartphone has the latest operating system installed. Connecting the Wi-Fi module is only possible when turned on for the first time or after resetting the settings to factory settings.
Equipment preparation and compatibility testing
Successful integration of a water heater into a network directly depends on proper infrastructure preparation. Ensure your router uses WPA2 encryption, as older security protocols may block smart device connections. Owners of dual-band routers are advised to temporarily separate the networks or force their phones to use the 2.4 GHz band.
To control it, you will need a smartphone or tablet running iOS or Android. The application Aqua Ariston Net (or its current equivalent Ariston Net) must be downloaded from the official app store. Please register an account in advance, as adding new hardware is not possible without authorization.
⚠️ Attention: The mobile app interface and feature names may vary slightly depending on the module firmware version and region of use. Always refer to the latest documentation in the "Help" section within the app.
Check the boiler's location relative to the access point. The Wi-Fi signal must be able to reliably reach the water heater's location. If the device is located in a niche or a closed cabinet, the signal strength may be critically low for reliable operation.
Installation and activation of the communication module
Water heaters series Velis Evo They often come with a communication module already installed, but it needs to be activated. In some models, the module must be inserted into a special slot on the front panel or inside the case, after the device is disconnected from the power supply. After powering on, the communication indicator should start blinking, indicating network search mode.
If the indicator light is off or remains solid, it may indicate that the module is locked or requires a reset. Activating Pairing Mode often requires pressing a specific combination of buttons on the control panel. Typically, this involves simultaneously pressing the temperature control buttons or the dedicated "On/Off" button for 5-7 seconds.
It's important to understand the difference between the module's operating mode and setup mode. In normal mode, the indicator may blink slowly, while in setup mode, it blinks rapidly. Rapid blinking indicates that the device is ready to receive commands from the smartphone.
What to do if the indicator does not blink?
If the Wi-Fi indicator doesn't respond to presses, try completely disconnecting the water heater for 10-15 seconds. Then, turn it on again and immediately try pairing. If this doesn't help, the module may be damaged or incompatible with your control board version.
Step-by-step setup via mobile app
The pairing process begins with launching the app on your smartphone. After logging into your account, click the "Add New Device" button. The system will prompt you to select a device category—in our case, a water heater. The app will automatically enter search mode or prompt you to scan the QR code located on the device's sticker or in the instructions.
Next comes a critical step: entering your Wi-Fi network details. The app will ask for the network name (SSID) and password. Make sure you enter the password correctly, observing capitalization. Even a single character error will prevent the water heater from connecting to the router.
After confirming the data, the configuration process will begin. During this time, your phone transmits network parameters to the water heater. Keep your smartphone no more than 1–2 meters away from the device. The process can take 30 seconds to 2 minutes.
☑️ Connection checklist
Once setup is complete, the indicator on the water heater's control panel should glow steadily or change to a flashing pattern, indicating a successful connection. The app will display the "Online" status, and you'll be able to see the current water temperature.
Table of indicators and their meaning
Understanding your device's alarms helps you quickly diagnose problems without having to call a service center. Ariston Velis Evo 50 equipped with an informative LED panel that reports the module status.
| Indicator status | Meaning | User action |
|---|---|---|
| Turned off | The module is turned off or there is no power supply | Check the power connection |
| Slow blinking | Standby / Searching for network | Wait or restart the search |
| Fast blinking | Pairing mode | Perform setup via the app |
| Constant light | Successful connection to Wi-Fi | Control is available via the app |
| Red color / Error | Connection or password error | Check the password and repeat the setup. |
Please note that the color indication may vary depending on the specific control board revision. In some versions, the error status may be indicated by all indicators flashing at once.
Solving common connection problems
The most common cause of connection failure is the use of 5 GHz networks. Wi-Fi modules in household appliances often operate only at 2.4 GHz. If your router combines both frequencies under one name, try temporarily separating them in the router settings or using the guest network only for the 2.4 GHz band.
Another common issue is the use of special characters in the Wi-Fi password. Some older firmware versions of the modules may not handle complex passwords correctly. As a test, try creating a temporary network with a simple alphanumeric password.
⚠️ Attention: Using public Wi-Fi networks (in hotels and cafes) with web-based authentication (Captive Portal) will prevent the water heater from connecting. A network with WPA/WPA2 password protection is required.
If the app says "Device not found," check the app's permissions on your smartphone. Android and iOS require geolocation and local network access to work with Wi-Fi modules. Without these permissions, data transfer is impossible.
Remote control functionality
Once successfully connected, you have extensive control over your microclimate. You can set the heating temperature precisely to the degree, something impossible with the buttons on the housing (in 5-degree increments). This optimizes energy consumption.
System Ariston Net Allows you to program a schedule. For example, you can set the water heating to run only at night if you have a dual-tariff meter, or when guests arrive. Consumption statistics will help you analyze how much energy is being used for heating.
An important feature is legionella protection. The app can automatically run a high-temperature water heating cycle once a week to disinfect the tank. You will also receive notifications about the need for maintenance or anode replacement.
Frequently Asked Questions (FAQ)
Is it possible to connect one water heater to multiple phones?
Yes, the system allows you to create a family or group of users. The device owner (administrator) can invite other users through the app by sending an invitation link. Guests will have access to basic management features, but they will not be able to delete the device or change basic network settings.
What should I do if the internet is down, but the Wi-Fi router is working?
If the router is running but there's no internet access, the water heater may remain connected to the local network but will not transmit data to the server. External app control (via mobile data) will be unavailable. Control may still be possible within the home network if the app supports local mode, but most often an active internet connection is required for authorization.
Do the settings reset when the power goes out?
No, the Wi-Fi module and its settings are saved in the internal memory. Once power is restored, the water heater will automatically attempt to connect to the previously saved network. If the router changes the device's IP address, the module will re-locate it using DHCP.
How to completely reset Wi-Fi settings on an Ariston Velis Evo?
A full reset typically requires holding the power button or a combination of buttons on the control panel for 10-15 seconds until the indicators flash in a specific pattern. The exact sequence depends on the software version and is described in the "Reset" section of the user manual.
