1. Уводзіны
The Legrand 199120 Drivia with Netatmo Connected Modular Load Shedder is an advanced energy management device designed to optimize your electrical consumption and prevent power outages due to overload. This device measures the total electrical consumption of your single-phase installation in real-time and allows you to monitor and manage your energy usage efficiently through the Home + Control application.
By using this connected load shedder, you can avoid untimely power cuts and control consumption peaks, potentially reducing your electricity contract costs. It intelligently manages your most energy-intensive appliances by progressively shedding them based on customizable priorities when overconsumption is detected, and automatically re-powers them once the risk subsides.

4. Настройка і ўстаноўка
The Legrand 199120 is designed for installation in an electrical panel on a DIN rail. It requires prior installation of a connected starter pack 'with Netatmo' to function.
4.1. Pre-installation Requirements
- A compatible electrical panel with available DIN rail space (1 module width).
- A Legrand 'with Netatmo' connected starter pack already installed and configured.
- A stable Wi-Fi network connection.
- The Legrand Home + Control application installed on your smartphone or tablet.
4.2. Этапы ўстаноўкі
- Адключыць харчаванне: Before starting any work, cut the main power supply to your electrical panel at the general circuit breaker. Verify that the power is off using a voltagэлектронны тэстар.
- Устанавіце прыладу: Install the Legrand 199120 Connected Modular Load Shedder onto an available DIN rail in your electrical panel. It occupies 1 module space.
- Connect the Current Transformer: Pass the main phase wire of your electrical installation through the closed measuring current transformer (toroid). Ensure the toroid is correctly oriented according to any markings. Connect the toroid's cable to the designated input terminals on the load shedder.
- Падключэнне да электрасілкавання: Connect the load shedder to the appropriate power supply terminals within your electrical panel as per the wiring diagram provided in the full product documentation (not included here).
- Аднавіць сілу: Once all connections are secure and verified, restore the main power supply to your electrical panel.
- Спалучэнне з праграмай: Open the Legrand Home + Control application on your smartphone. Follow the in-app instructions to add and pair the new connected load shedder to your existing 'with Netatmo' installation. This typically involves a pairing process initiated on the device and confirmed in the app.

5. Аперацыя
The Legrand 199120 load shedder operates in conjunction with the Legrand Home + Control application to provide real-time monitoring and intelligent load management.
5.1. Маніторынг у рэжыме рэальнага часу
- Once installed and paired, the device automatically transmits real-time total electrical consumption data to the Home + Control app.
- Вы можаце view daily, weekly, monthly, and annual consumption statistics in both monetary value (€) and kilowatt-hours (kWh) within the app.
5.2. Load Shedding Configuration
The primary function of the load shedder is to prevent your main circuit breaker from tripping due to overconsumption. This is achieved by temporarily disconnecting non-priority loads.
- Set Thresholds: In the Home + Control app, configure your subscribed power threshold and the maximum consumption limit. These values define when load shedding should be initiated.
- Prioritize Loads: Within the app, you can customize the priority of your connected appliances. This allows you to define which appliances should be shed first (lower priority) and which should remain powered (higher priority) during an overconsumption event.
- Аўтаматычнае кіраванне: When the total consumption exceeds the set threshold, the load shedder will progressively disconnect appliances according to your defined priorities. As soon as the consumption returns to a safe level, the shed appliances will be automatically re-powered.
