4. Setup

4.1 Power Connection

1. Ensure the power source is off before making any connections.
2. Connect a USB 5V power supply to the USB port or a DC 7-32V power supply to the designated DC input terminals.

4.2 Sensor Connection

1. Carefully plug the 1-meter DS18B20 temperature probe into the sensor socket on the controller.
2. Position the sensor in the area where temperature monitoring is required.

4.3 Relay Wiring

The controller features four dry contact relay outputs (NC, COM, NO) for each channel. These outputs act as switches for your external appliances.

1. Identify the appropriate terminals (NC, COM, NO) for the appliance you wish to control.
2. Connect your appliance's control circuit to the COM and either NO (Normally Open) or NC (Normally Closed) terminals, depending on your desired default state.
3. Important: The maximum load current for each channel is 10A. If controlling appliances with higher power requirements, a contactor must be used to prevent damage to the controller.

4.4 App Installation

1. Download the 'Tuya Smart Life' application from your smartphone's app store (available on iOS and Android).
2. Register or log in to your Tuya Smart Life account.

4.5 Device Pairing

1. Ensure your Wi-Fi router is operating on the 2.4GHz frequency band. This device does not support 5GHz Wi-Fi networks.
2. For optimal pairing, place the controller close to your Wi-Fi router.
3. Power on the controller. The network indicator LED should begin to flash, indicating it's in pairing mode. If not, press and hold the Reset button until it flashes.
4. Open the Tuya Smart Life app, tap the '+' icon to add a device, and select the appropriate device type (e.g., 'Switch' or 'Temperature Controller').
5. Follow the on-screen instructions in the app to complete the pairing process, including entering your Wi-Fi network credentials.
6. Once successfully paired, the network indicator LED will stop flashing and remain solid.
7. The device also supports Bluetooth for local control when offline (within range) and 433Mhz RF (fixed code) for additional remote control options.

5. Operating Instructions

5.1 App Interface Overview

After successful pairing, you can access the controller's functions through the Tuya Smart Life app. The interface provides options for:

• Remote ON/OFF: Manually switch each channel on or off.
• Rename: Customize the name of the device and individual channels.
• Schedule/Timing: Set up automated schedules, countdowns, and cycle timers.
• Temperature Calibration: Adjust sensor readings for accuracy.
• Temperature Sensitivity: Configure the responsiveness of temperature-based actions.
• Real-time Monitoring: View current temperature and historical data.
• Device Sharing: Share control of the device with other Tuya accounts.

5.2 Temperature-Based Automation

The core functionality of this controller is to automate appliances based on temperature. You can set specific temperature ranges to trigger the ON/OFF state of connected devices.

1. In the app, navigate to the device settings or automation section.
2. Create a new automation rule.
3. Select the temperature sensor as the trigger condition.
4. Define the temperature threshold (e.g., 'when temperature > 25°C').
5. Choose the action (e.g., 'Switch 1 ON' or 'Switch 2 OFF').
6. Save the automation rule.

7. Troubleshooting

• Device not connecting to Wi-Fi:
  • Ensure your Wi-Fi network is 2.4GHz. 5GHz networks are not supported.
  • Check the Wi-Fi signal strength at the device's location.
  • Restart your Wi-Fi router and the controller.
  • Verify that the correct Wi-Fi password has been entered during pairing.
  • Try resetting the device to factory settings (press and hold the Reset button) and re-pairing.
• Device appears offline in the app:
  • Check your internet connection and Wi-Fi router status.
  • If within Bluetooth range, you may still be able to control the device locally via the Tuya app's Bluetooth function.
• Connected appliance not switching:
  • Verify all wiring connections (NO, COM, NC) are secure and correct.
  • Ensure the load current of the appliance does not exceed 10A per channel. For high-power devices, a contactor is required.
  • Check the temperature automation rules or schedules in the Tuya app to ensure they are correctly configured and active.
• Inaccurate temperature readings:
  • Ensure the temperature sensor is properly connected to the controller.
  • Verify the sensor is placed in the desired monitoring environment and not exposed to direct heat sources or drafts that could skew readings.
  • Use the temperature calibration feature in the Tuya app to fine-tune the sensor's readings if necessary.
