Connecting electric or solid fuel boilers of the brand Evan Connecting to a wireless network allows for remote monitoring of temperature conditions, which is especially important for country houses where defrosting the system while the owners are away is unavoidable.

The setup process may seem complicated at first glance, but with basic knowledge of network interfaces and careful study of the instructions, the procedure takes little time. In this article, we'll cover all the details of connecting Evan controllers to a router via Wi-Fi or using GSM modules that support internet connection.

It is worth noting right away that direct connection Wi-Fi access isn't available for all boiler models, as many require additional expansion boards or external communication modules. Understanding the architecture of your heating system is the first step to successfully digitalizing your equipment and creating a comfortable indoor climate.

Checking the compatibility of equipment and modules

Before you begin setting up your network parameters, you need to make sure that your boiler Evan Technically capable of interacting with wireless networks. Basic models often only come equipped with terminals for connecting room thermostats, so implementing Smart Home features requires upgrading the device with specialized controllers.

The most common solution is to use series controllers ZET or specialized GSM modules that have slots for SIM cards and antennas. If you plan to use a Wi-Fi router for data transfer, make sure the module you choose supports local network operation via TCP/IP protocols or has a built-in Wi-Fi adapter.

⚠️ Caution: Do not attempt to connect the boiler's low-voltage control contacts directly to the router ports without using an intermediate controller, as this is guaranteed to result in the electronics being burned out.

It's also important to check the firmware version of the installed controller, as older versions may not support modern Wi-Fi network encryption standards. Updating the firmware often resolves connection issues and allows for the use of advanced mobile app functionality.

Network preparation and necessary tools

Successful integration of a boiler into a network depends on proper infrastructure preparation, including a stable router and correct security settings. You'll need to know your network's SSID, Wi-Fi password, and, in some cases, reserve a static IP address for the device in the router's DHCP server settings.

To complete the setup, please have a laptop or smartphone with internet access, as well as an Ethernet cable if the controller supports a wired connection for initial configuration. Make sure the router operates in the 2.4 GHz band, as many industrial and consumer IoT modules do not support the 5 GHz frequency.

  • 📡 A stable Wi-Fi signal source with coverage at the boiler installation location.
  • 📱 A smartphone with the app installed Evan Comfort or similar software for your model.
  • 🔌 Twisted pair cable for initial setup if wireless mode is not available.
  • 🔑 Authorization data from your personal account or the manufacturer's cloud service.

Pay special attention to the router's location: a metal boiler room enclosure or thick walls can shield the signal, resulting in connection interruptions. If necessary, use Wi-Fi repeaters or extended antennas for the communication modules.

Physical connection of the communication module

The communication module installation process begins with the mandatory de-energization of the boiler and all devices connected to it, as the work is performed inside the electrical control panel. After removing the controller's protective cover, locate the external module connector, usually marked as RS-485, UART or has a specific connector for GSM/Wi-Fi boards.

If you're using a GSM module with GPRS/3G/4G data transfer, install a SIM card from any carrier with the data service activated and the PIN code request disabled. For Wi-Fi modules, connect the antenna to the corresponding connector on the board and secure the module in the housing.

After physical installation, power up the boiler and wait for the self-diagnostics procedure to complete, which is usually indicated by the status indicator. The LEDs on the controller should light up, indicating communication between the main control unit and the installed communication module.

In some models, it is necessary to activate support for the external module through the menu of the controller itself, by switching the corresponding parameter to the value Enabled or OnWithout this software activation, the controller will not poll the communication module and transmit data to the network.

Configuring Wi-Fi connection settings

Network settings are most often configured through the web interface of the controller itself, which provides its own access point, or through specialized software on a PC. Access the controller settings menu using the button sequence on the control panel and go to the section Network Settings or Wi-Fi Config.

In the list of available networks that opens, find the SSID of your home router and enter the password, taking care to ensure that the characters are case-sensitive. If automatic search doesn't work, select manual entry and select the encryption type, which typically corresponds to the standard WPA2-PSK.

Parameter Default value Recommended value Note
Opening hours Client Client To connect to a router
Encryption type Auto WPA2-PSK The most compatible standard
Communication port 8080 8080 or 502 Depends on the protocol
DHCP Enabled Enabled To obtain IP automatically

After saving the settings, the controller will attempt to establish a connection with the router, which may take up to 60 seconds. A successful connection is confirmed by a change in color or blinking pattern of the network indicator on the controller and module.

⚠️ Note: Controller interfaces may differ depending on the year of manufacture and firmware version, so check the names of menu items with the official instructions for your specific modification.

Registration in the application and cloud service

To enable remote control, you need to register the device in the manufacturer's cloud service or a third-party platform that supports your controller's protocol. Download the official app. Evan Comfort (or similar, as indicated in your passport) on your smartphone and create an account using a valid email address.

In the app, select the option to add a new device and scan the QR code located on the controller housing or in the documentation, or enter the serial number manually. The system will automatically detect the model and offer to set up notifications about critical changes in the heating system.

What should I do if the app doesn't detect the device?

Make sure the smartphone and controller are on the same local network (if configured locally) or that the controller has an internet connection indicator. Also, check whether the router's firewall is blocking outgoing connections from the device.

Once the device is linked, you can not only monitor the temperature of the coolant and air in the room, but also create schedules, configure scenarios, and receive push notifications about alarms. Remote access allows you to quickly respond to voltage surges or temperature drops, preventing the system from freezing.

Diagnostics and troubleshooting

During operation, situations may arise where the connection to the boiler is lost or the parameters are displayed incorrectly. The first step in diagnostics should always be checking the status indicators: if the red network error indicator is illuminated, check the signal strength and the correct password.

A common issue is the router's IP address changing during a reboot, causing the app to lose access to the device if a static IP isn't reserved. Issues can also arise when updating the router's firmware, which changes security standards or disables older protocols.

  • 🔄 Reboot the controller and router to update network leases.
  • 📡 Check the Wi-Fi signal strength at the boiler installation point using your smartphone.
  • 🔒 Make sure MAC address filtering is not enabled in your router settings.
  • ☁️ Check the status of the manufacturer's servers for maintenance.

If software methods don't help, reset the network settings on the controller to factory defaults and repeat the connection process. In complex cases, it may be necessary to reflash the communication module via the USB port using a specialized converter.
