Modern heating systems are no longer just a collection of pipes and radiators, but rather complex engineering systems that require constant monitoring. Owners of private homes and cottages often face the need for remote temperature monitoring to prevent freezing of the system or, conversely, excessive energy consumption. To address these challenges, EVAN has developed a specialized system. control module, which is integrated into controllers and allows data to be transmitted to the user's smartphone.
The device is a compact unit that connects to the boiler or heat pump's electronics and provides two-way wireless communication. This allows you to not only receive alarms but also fully control the indoor climate from anywhere in the world. GSM Wi-Fi Climate is a key element for creating a complete system smart home based on EVAN equipment.
In this article, we'll detail the device's functionality, installation methods, and software configuration details. Understanding how the module operates will help you avoid common installation errors and ensure the stable operation of your entire heating system for years to come.
Purpose and functionality of the module
The device's primary function is to provide remote access to the heat generator's operating parameters. The module reads data from temperature sensors, records the status of circulation pumps and heating elements, and monitors the presence of voltage in the network. All this information is transmitted to the user via GSM channel or local network Wi-Fi, providing reliable communication even in the absence of wired internet.
The system's functionality allows for various operating scenarios, such as maintaining a minimum temperature when residents are away and warming the house up when they arrive. This is especially relevant for country houses, where constantly running the heating at full power is economically impractical. Controller Automatically switches operating modes according to a set schedule or command from a mobile application.
⚠️ Note: The module's functionality directly depends on the firmware version of the EVAN controller it is connected to. Make sure your primary equipment supports external communication modules.
The device also functions as an emergency alert system. If an emergency occurs, such as coolant overheating, pump failure, or pressure drop, the module immediately sends a push notification or SMS. This enables the owner to quickly respond and call emergency services, preventing serious damage to expensive equipment.
Operating principle and compatibility with EVAN equipment
The module acts as an intermediary between the heating appliance's electronics and the manufacturer's server. Data from the controller is received by the module, which packages it into packets and sends it via a SIM card or router to cloud storage. A user app installed on a smartphone requests the current system status from the server, displaying temperature graphs and equipment statuses.
The most important aspect is compatibility. Module GSM Wi-Fi Climate designed specifically for the EVAN series of controllers, such as SKT And VKAttempting to connect to third-party or older boiler models without the appropriate interface may result in incorrect operation or complete failure of the control system.
For correct operation, the following technical nuances must be taken into account:
- 📡 The module requires a stable cellular network signal at the boiler installation location, especially if only the GSM channel is used.
- ⚡ The device's power supply must be protected from power surges; it is recommended to use uninterruptible power supplies.
- 🔌 The connection is made through a special connector on the controller board, often marked as
RS-485orModule.
When using a Wi-Fi connection, the module can operate in access point mode for initial setup, then switch to client mode to connect to the home network. This simplifies the configuration process, as it eliminates the need to connect a computer directly to the control board.
Specifications and installation requirements
The device is designed for operation in boiler rooms, but has certain temperature and humidity limitations. The module's housing is made of durable plastic, protecting the electronic components from dust, but direct exposure to water or condensation is prohibited. Installation must comply with electrical safety requirements.
Key parameters to consider when choosing an installation location:
- 🌡️ The operating temperature range is usually from -10 to +40 degrees Celsius.
- 📶 The GSM antenna should be placed in an area with reliable signal reception if the signal level inside the control cabinet is low.
- 🔋 The module's current consumption is low, but it requires a stable voltage of 12 or 24 volts, depending on the controller model.
A standard Mini or Micro SIM card is used for connection, depending on the module's slot. It's important to disable the PIN code request on the card when powering it on; otherwise, the module will be unable to register on the network or connect to the server.
| Parameter | Meaning / Description | Note |
|---|---|---|
| Connection type | GSM / Wi-Fi | Dual-band module |
| Supply voltage | 12-24 V DC | Depends on the controller |
| Interface | RS-485 | Modbus protocol |
| Storage temperature | -40...+70 °C | No condensation |
Installing the module requires disconnecting the power supply to the entire boiler. This is a critical safety precaution, as hot-plugging the connector can damage both the module itself and the heat generator's main control board.
Step-by-step installation and connection instructions
The installation process begins with removing the boiler's front panel or control cabinet. Access the controller's electronic board. Locate the connector for additional modules; it's often located at the bottom of the board or on the side and marked accordingly.
☑️ Preparing for module installation
Carefully align the module connector pins with the mating connectors on the board and firmly connect them. Make sure the latches click into place. Then install the antenna by screwing it to the corresponding connector on the module housing or by routing it through the opening in the cabinet.
⚠️ Caution: The antenna cannot be connected or disconnected when the module is powered on, this may cause the radio frequency path to burn out.
After physical installation, assemble the boiler body and apply power. The module's indicators should begin flashing, indicating the boot process and network search. If there is no indicator, check for voltage at the module's power contacts using a multimeter.
What to do if the module is not detected?
If the indicators don't light after powering on, check the connection polarity (if the module is universal) and the presence of 12V on the controller's power bus. Sometimes, activating the module function in the EVAN controller's menu is required.
Software setup and registration
To manage the system, you need to install the official EVAN mobile app, available for iOS and Android. After installation, launch the app and create a user account. This step is required to link the equipment to your personal account.
The process of registering a device in the application is as follows:
- Click the "Add device" button in the main menu of the application.
- Select the connection type (Wi-Fi or GSM) and the model of your module.
- Enter the module serial number found on the housing sticker or scan the QR code.
- Give the device a name (e.g. "Boiler in the house") for easy identification.
When setting up via Wi-Fi, the app will prompt you to enter your home wireless network details (SSID and password). The module will attempt to connect to the router. If the connection is successful, the Wi-Fi indicator on the module will either glow solid or blink.
If using a GSM channel, ensure that the data service (GPRS/3G/4G) is activated on the SIM card, even if the primary control is via SMS. This is necessary for the prompt delivery of push notifications and the functionality of the app's graphical interface.
System management and troubleshooting
The EVAN app interface not only allows you to monitor the current temperature but also manage operating modes. You can switch heating stage powers, turn circulation pumps on and off, and change the target coolant temperature. All changes are applied instantly.
However, users may experience connection issues. If the app shows "Offline" status, check the following:
- 📶 Cellular network signal level at the location where the boiler is installed.
- 💰 Balan
