2. Safety Information

• Read all instructions carefully before use.
• Ensure the device is connected to a power source that matches its voltage requirements (100~240VAC, 50Hz/60Hz).
• Do not exceed the maximum total power output of 1100W/110V or 2200W/220V for connected heating and cooling devices.
• Keep the device and probe away from water unless the probe is specifically designed for immersion (IP68 rated NTC probe is water-resistant).
• Do not disassemble or modify the device. Refer all servicing to qualified personnel.
• Unplug the device from the power outlet before cleaning or performing any maintenance.

3. Package Contents

The Inkbird ITC-308-WIFI package typically includes the following items:

• Inkbird ITC-308-WIFI Thermostat
• NTC Temperature Sensor (2m, IP68 Stainless Steel Probe)
• User Manual

4. Product Features

• Wi-Fi Connectivity: Connects to a 2.4 GHz Wi-Fi network for remote control and monitoring via the InkbirdSmart or Inkbird Pro app.
• Dual Relay Output: Features two outlets for simultaneous connection of heating and cooling devices.
• Temperature Range: Measures temperatures from -40°C to 100°C (-40°F to 212°F) with 0.1°C accuracy.
• Temperature Unit Switch: Easily switch between Celsius (°C) and Fahrenheit (°F) display.
• High/Low Temperature Alarms: Configurable alarms notify you via the app if the temperature exceeds preset maximum or minimum limits.
• Probe Error Alarm: Alerts you if the temperature probe malfunctions.
• Temperature Calibration: Allows for fine-tuning of temperature readings for enhanced accuracy.
• Refrigeration Compressor Delay Protection: Protects cooling equipment by providing a delay before restarting the compressor.
• Plug-and-Play Design: Easy to set up and use.

The thermostat supports both cooling and heating functions simultaneously, as depicted by a refrigerator for cooling and a radiator for heating.

The device provides instant temperature alarms, sending notifications to your smartphone when the temperature exceeds preset limits.

5. Setup

5.1 App Installation

Download the 'InkbirdSmart' or 'Inkbird Pro' application from your smartphone's app store (available for iOS and Android).

5.2 Wi-Fi Connection

1. Plug the ITC-308-WIFI into a power outlet.
2. Open the Inkbird app and follow the on-screen instructions to add a new device.
3. On the ITC-308-WIFI, press and hold the 'WiFi' button until the Wi-Fi indicator light blinks rapidly.
4. Confirm the indicator light is blinking rapidly in the app and proceed with the connection.
5. Enter your 2.4 GHz Wi-Fi network password when prompted. The device will connect to your network.
6. Once connected, the device will appear in your app, allowing you to monitor and control it remotely.

Remote monitoring and control are possible via the Inkbird app on a smartphone, allowing users to check and adjust settings from anywhere with a 2.4GHz Wi-Fi connection.

6. Operating Instructions

The ITC-308-WIFI allows for precise control of heating and cooling devices. Parameters can be set directly on the device or through the Inkbird app.

6.1 Key Parameters

• TS (Target Temperature): The desired temperature you want to maintain.
• HD (Heating Difference): The temperature difference below TS at which the heating device will activate.
• CD (Cooling Difference): The temperature difference above TS at which the cooling device will activate.

6.2 Setting Temperature Parameters

To set the parameters, use the 'SET' button and arrow keys on the device, or adjust them directly within the Inkbird app. For example, to maintain a target temperature (TS) of 16°C with a heating difference (HD) of 2°C and a cooling difference (CD) of 3°C:

• Set TS = 16°C.
• Set HD = 2°C. The heater will turn on if the temperature drops to 14°C (TS - HD) and turn off when it reaches 16°C.
• Set CD = 3°C. The cooler will turn on if the temperature rises to 19°C (TS + CD) and turn off when it reaches 16°C.

This diagram illustrates how to set the target temperature (TS), heating difference (HD), and cooling difference (CD) to maintain a desired temperature range. For example, to maintain 16°C within a range of 14°C to 19°C, set TS=16, HD=2, and CD=3.

6.3 Other Settings

• Temperature Unit Switch: Change the display unit between Celsius and Fahrenheit in the app settings.
• Temperature Calibration: Adjust the temperature reading if there is a known discrepancy with a reference thermometer.
• Refrigeration Delay: Set a delay time (e.g., 0-10 minutes) to prevent rapid cycling of the compressor, which can extend its lifespan.
• High/Low Temperature Alarm Limits: Define the upper and lower temperature thresholds that will trigger an alarm notification.

7. Maintenance

• Cleaning the Device: Wipe the main unit with a soft, dry cloth. Do not use abrasive cleaners or immerse the unit in water.
• Probe Care: Regularly inspect the NTC probe for any signs of damage or corrosion. Clean the probe gently if necessary, ensuring it is free from debris that could affect readings.
• Software Updates: Check the Inkbird app periodically for firmware updates to ensure optimal performance and access to new features.

8. Troubleshooting

• Device Not Powering On: Ensure the device is securely plugged into a functional power outlet. Check the power cord for any damage.
• Incorrect Temperature Readings: Verify the NTC probe is correctly connected and positioned. Check for any physical damage to the probe. Perform a temperature calibration if a consistent offset is observed.
• Wi-Fi Connection Issues: Ensure your Wi-Fi network is 2.4 GHz. Check that the device is within range of your Wi-Fi router. Restart the device and attempt to reconnect via the app.
• Heating/Cooling Device Not Activating: Check the power connection of the heating/cooling device to the thermostat. Verify that the TS, HD, and CD parameters are set correctly and that the current temperature is outside the set range.
• Alarm Triggering Frequently: Review your high and low temperature alarm limits (HH/LL) in the app to ensure they are appropriate for your application.
• Probe Error Alarm: If a probe error alarm occurs, check the probe connection. If the issue persists, the probe may need replacement.
