3. Setup
Follow these steps to set up your INKBIRD Plug in WiFi Thermostat:
- Unpack the Device: Carefully remove the thermostat and temperature probe from its packaging.
- Plug In: Insert the thermostat into a standard 120V AC power outlet.
- Connect Probe: Plug the temperature probe into the designated port on the thermostat. Ensure it is securely connected.
- Download App: Download the INKBIRD app from your smartphone's app store (iOS or Android).
- Register/Log In: Open the INKBIRD app and create an account or log in if you already have one.
- Add Device: Follow the in-app instructions to add your C236TWIFI-15A-US thermostat. This typically involves putting the device into pairing mode (refer to the device's display or quick start guide for specific button presses) and connecting it to your home WiFi network.
- Placement: Position the temperature probe in the area where you need to monitor and control the temperature. Ensure it is not directly exposed to heat sources or drafts that could skew readings.
4. Operating Modes
The INKBIRD thermostat offers flexible programming with four primary working modes:
Figure 4.1: Overview of the four flexible programming modes.
4.1. Temperature Mode (TEMP. MODE)
In this mode, the device controls your connected appliance based solely on temperature readings from the probe. You set a START temperature and a STOP temperature.
- Heating Function: When the START temperature is set lower than the STOP temperature, the outlet functions as a heater control. The appliance turns ON when the temperature falls below START and turns OFF when it rises above STOP.
- Cooling Function: When the START temperature is set higher than the STOP temperature, the outlet functions as an AC control. The appliance turns ON when the temperature rises above START and turns OFF when it falls below STOP.
4.2. Time Mode (TIME MODE)
This mode allows you to turn the device on or off at specific times you set, functioning as a programmable timer independent of temperature.
4.3. Temperature Time Mode (TEMP TIME MODE)
This advanced mode combines temperature and time control. The device will control your appliance based on both the set temperature and specific time periods, offering more nuanced control for complex applications.
4.4. Manual Mode (MANUAL MODE)
In Manual Mode, you can manually turn your device on or off from a remote location via the INKBIRD app. This provides immediate control without relying on programmed settings.

5. Maintenance
To ensure optimal performance and longevity of your INKBIRD thermostat, follow these simple maintenance guidelines:
- Cleaning: Wipe the thermostat and probe with a soft, dry cloth. Do not use abrasive cleaners or immerse the unit in water.
- Probe Care: Ensure the temperature probe is clean and free from debris. Avoid bending or kinking the probe cable excessively.
- Storage: If storing the device for an extended period, unplug it from the power outlet and store it in a cool, dry place.
6. Troubleshooting
Refer to the table below for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on. | No power from outlet; device malfunction. | Check the power outlet with another appliance. Ensure the thermostat is properly plugged in. |
| Cannot connect to WiFi. | Incorrect WiFi password; out of range; router issues. | Verify WiFi password. Move thermostat closer to router. Restart router. Ensure 2.4GHz WiFi is used. |
| Temperature readings are inaccurate. | Probe not properly inserted; probe damaged; probe exposed to external factors. | Ensure probe is fully inserted. Check probe for visible damage. Reposition probe away from direct heat/cold sources. Perform temperature calibration via the app if available. |
| Appliance not turning on/off as expected. | Incorrect mode selected; START/STOP temperatures set incorrectly; cooling delay active. | Verify the selected operating mode. Double-check START and STOP temperature settings. Adjust cooling delay if necessary. |
| High/Low temperature alarm sounds frequently. | Alarm thresholds set too close to operating range; actual temperature fluctuation. | Adjust the high/low alarm thresholds in the app to a wider range. Investigate environmental factors causing temperature swings. |
| Settings lost after power outage. | This should not happen. | The device features power-off memory. If settings are lost, contact support. |
