6. Setup and Installation
6.1. Battery Installation
The TRV requires 2xAA batteries (not included). To install:
- Unscrew the top cover of the TRV.
- Insert 2xAA batteries, ensuring correct polarity.
- Replace the top cover.
6.2. Mounting the TRV to the Radiator
The TRV comes with various adapters to ensure compatibility with different valve types. Identify your radiator valve type and use the appropriate adapter.
Common valve types and their dimensions:
- RA: 23mm diameter, 63mm height.
- RAV: 34mm diameter, 59mm height.
- RAVL: 26mm diameter, 59mm height.
- Comap: 28mm diameter, 49.5mm height.
- T+A Herz: 27.5mm diameter, 51mm height.
- Herz: 27.5mm diameter, 50mm height.
It is recommended to confirm the model first if the thread size is not M30*1.5mm, to avoid incorrect orders.
- Remove your existing thermostatic head from the radiator valve.
- Select the correct adapter for your valve type.
- Attach the adapter to the radiator valve.
- Screw the MOES TRV onto the adapter until it is securely fastened.
6.3. Connecting to a ZigBee Wireless Gateway (Hub)
A ZigBee wireless gateway (hub) is required for smart functions, app control, and voice control. Ensure you have a compatible ZigBee 3.0 hub.
- Power on your ZigBee wireless gateway and ensure it is connected to your WiFi router.
- Download the Tuya Smart Life App on your smartphone.
- Open the app and add your ZigBee gateway.
- Follow the app instructions to add the TRV to your gateway. This typically involves putting the TRV into pairing mode (refer to the specific pairing steps in the TRV's user guide, usually a long press on a button).
- Once paired, you can control the TRV via the app.
7. Operating Instructions
7.1. Manual Control
You can adjust the temperature directly on the TRV using the physical buttons:
- Use the Up (+) and Down (-) buttons to increase or decrease the target temperature.
- The LED display will show the current and set temperatures.
7.2. App Control (Tuya Smart Life)
After successfully connecting the TRV to the Tuya Smart Life App via the ZigBee gateway, you can control it remotely:
- Open the Tuya Smart Life App.
- Select your TRV device.
- Adjust the temperature, change modes, or set schedules from the app interface.
7.3. Voice Control
Integrate your TRV with Amazon Alexa or Google Assistant for hands-free control:
- Ensure your TRV is connected to the Tuya Smart Life App.
- Link your Tuya Smart Life account to Amazon Alexa or Google Assistant through their respective apps.
- Use voice commands such as: "Alexa, set the bedroom temperature to 22°C." or "Hey Google, what's the temperature in the living room?"
7.4. Programmable Schedule
Set up a 5+2 weekly schedule to automate your heating based on your routine:
- Access the scheduling options in the Tuya Smart Life App.
- Define different temperature settings for various time periods (e.g., morning, daytime, evening, night) for weekdays (5 days) and weekends (2 days).
- Available modes include: Auto-mode, Manual-mode, TempHand-mode, and Holidays-mode.
7.5. Special Features
- Eco-Mode: An energy-saving mode that can be activated via the app.
- Low Battery Tip: The device will provide a low battery reminder.
- Open Window Detection: The TRV can detect open windows and temporarily adjust heating to save energy. This feature can be customized in the Smart Life App.
- Room Temperature Graph: The app provides a temperature curve graph to monitor room temperature in real-time, helping you understand heating patterns.
8. Maintenance
8.1. Battery Replacement
When the low battery reminder appears on the display or in the app, replace the batteries promptly to ensure continuous operation. Use 2xAA batteries.
- Unscrew the top cover of the TRV.
- Remove the old batteries.
- Insert new 2xAA batteries, observing correct polarity.
- Replace the top cover.
8.2. Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
9. Troubleshooting
- Device not responding: Check battery levels. Ensure the ZigBee gateway is powered on and connected to the internet. Verify the TRV is within range of the gateway.
- Temperature inaccuracy: The internal sensor is sensitive. If an external temperature sensor is used (e.g., in a Tuya scenario), ensure the TRV is configured to use that sensor's readings for more accurate room temperature control, as the TRV itself can be affected by the radiator's heat.
- Difficulty pairing: Ensure the TRV is in pairing mode and the gateway is ready to add new devices. Refer to the specific pairing instructions in the TRV's user guide.
- Valve sticking: While not explicitly stated as a feature, regular manual operation (fully opening and closing the valve) can help prevent sticking due to calcification.
- Noise during operation: The TRV operates by moving a valve. Some minimal noise during this process is normal. If the noise is excessive, ensure the installation is secure and there are no obstructions.
10. User Tips
- Battery Life: With 1800 mAh batteries, expect approximately 20 months of battery life (based on reported 5% consumption per month).
- External Sensors: For more precise room temperature control, especially if the TRV is directly on a hot radiator, consider using an external wireless temperature sensor and configuring scenarios in the Tuya Smart Life app to use its readings.
- Child Lock: The child lock feature can be enabled/disabled via the app.
- Manual Override: In case of internet outage or malfunction, the TRV can still be operated manually using the physical buttons.
- Group Control: For rooms with multiple radiators, you can group TRVs in the app to control them simultaneously, ensuring consistent temperature across the room.
