ATORCH GR2PWS Tuya WiFi Smart Din Rail Energy Meter Instruction Manual

1. Produs terminatview

The ATORCH GR2PWS is a smart Din Rail energy meter designed for real-time monitoring of voltage, current, power, and energy consumption in home and industrial settings. It features a 1.50-inch TFT-LCD HD display and supports WiFi connectivity for remote control and data analysis via the Tuya or Smart Life mobile applications. This model (GR2PWS) includes a built-in latching relay for prompt alarm and power cut-off functionality.

Variante de produs:

• Basic version (GR2P): Only provides prompt alarms; does not cut off power.
• WiFi version (GR2PW): Provides prompt alarms; does not cut off power.
• WiFi + Relay Version (GR2PWS): Provides prompt alarms and can cut off power.

Attention: This product is designed for unidirectional current measurement and cannot be used in solar power generation systems as it does not handle negative current.

2. Configurare și instalare

2.1 Despachetarea

Carefully unpack the energy meter and ensure all components are present:

• ATORCH GR2PWS Smart Din Rail Energy Meter (or GR2PW/GR2P variant)
• Manual de utilizare

2.2 Instalare fizică

The meter is designed for installation on a standard 35mm DIN rail. It can be easily clipped onto the rail without the need for screws.

2.3 Schema electrică

Important: Strictly follow the schematic diagram for wiring. Ensure correct wiring to prevent damage to the device or electrical system. The measured voltage and current should not exceed the calibration range.

Note on Initial Power-on (GR2PWS):

When the GR2PWS meter is first powered on, the built-in magnetic retention relay needs to be reset. This process takes more than ten seconds, during which the output will be maintained (delay protection). Over-limit protection functions (such as overvoltage, subvoltage, overcurrent, and overpower protection) will only take effect once startup is complete and the measurement interface is displayed. It is recommended to connect an air switch at the output end and wait for the meter to fully start before turning on your device's air switch.

2.4 App Download and WiFi Pairing

To utilize the smart features, download the 'Tuya' or 'Smart Life' app from Google Play (Android) or Apple App Store (iOS).

WiFi Connection Steps (for meters with WiFi modules):

1. Download the 'Smart Life' or 'Tuya' App.
2. After powering on, the device's red light flashes and remains on to enter distribution network mode, waiting for WiFi connection.
3. Follow the in-app instructions to add the device. You will need to select your WiFi network (2.4GHz only) and enter the password.
4. Once paired, the app will display the device interface.

It also shows remote control via the mobile app.

3. Instrucțiuni de utilizare

3.1 Interfață de afișare

The meter features a 1.50-inch TFT-LCD HD display panel (240x320 RGB Dot-matrix) that shows various electrical parameters in real-time. You can switch between Chinese and English interfaces.

3.4 Electricity Price Settings

The meter supports three electricity payment modes:

• Single rate electricity price: For basic calculation of electricity bills.
• Tiered electricity prices: Allows setting two types of electricity tariff coefficients (e.g., different rates for consumption above/below a certain kWh threshold).
• Peak and valley electricity prices: Enables setting different prices for specific time segments throughout the day (e.g., 00-07H, 07-11H, 11-19H, 19-00H).

3.5 Prepayment Function (GR2PWS only)

The GR2PWS model supports a prepayment function. When enabled, you can recharge the quantity of electricity (kWh). If the remaining energy is insufficient, the meter will automatically prompt you. When the remaining available power capacity reaches zero, the alarm will be disconnected, and power will be cut off.
