3. Setup Instructions
3.1 Initial Connection
- Plug the INKBIRDPLUS Digital Thermostat Outlet into a standard 110V-120V AC power outlet.
- Connect your heating or cooling appliance (e.g., heater, fan, refrigerator) to the outlet on the thermostat. Ensure the appliance's power consumption does not exceed 15A/1800W.
- Place the temperature probe in the desired location where you want to monitor and control the temperature. Ensure the probe is not directly exposed to heat sources or drafts that could skew readings.
4. Operating Instructions
4.1 Temperature Control Mode (Heating/Cooling)
The device operates in either heating or cooling mode based on your set temperatures.
Image 4.1: Example applications for heating and cooling control.
- Setting Heating Mode: Set the 'Start Temperature (ON)' to be lower than the 'Stop Temperature (OFF)'. The device will activate the connected appliance when the measured temperature drops below the 'Start Temperature' and turn it off when it reaches the 'Stop Temperature'.
- Setting Cooling Mode: Set the 'Start Temperature (ON)' to be higher than the 'Stop Temperature (OFF)'. The device will activate the connected appliance when the measured temperature rises above the 'Start Temperature' and turn it off when it drops to the 'Stop Temperature'.
To adjust temperature settings:
- Press the SET button once. The 'Start Temperature (ON)' will flash.
- Use the UP or DOWN buttons to adjust the desired 'Start Temperature'.
- Press SET again. The 'Stop Temperature (OFF)' will flash.
- Use the UP or DOWN buttons to adjust the desired 'Stop Temperature'.
- Press SET a third time to confirm and exit the setting mode. The display will return to showing the measured temperature.
4.2 Timing Functions
The thermostat offers four timing modes (F01-F04). Press the MODE button repeatedly to cycle through these options.
F01: Cycle Timer Mode
This mode allows the appliance to cycle ON and OFF for set durations. For example, ON for 12 hours, then OFF for 12 hours, repeating.

F02: Countdown ON Mode
The appliance will remain OFF for a set countdown period, then turn ON and stay ON indefinitely.

F03: Countdown OFF Mode
The appliance will remain ON for a set countdown period, then turn OFF and stay OFF indefinitely.

F04: Countdown ON and Countdown OFF Mode
The appliance will turn ON for a set duration, then turn OFF for another set duration, and then stay OFF indefinitely.

To set timing functions (for any F01-F04 mode):
- Press the MODE button until the desired timing mode (F01-F04) is displayed.
- Press the SET button. The first time parameter (e.g., ON hours for F01) will flash.
- Use the UP or DOWN buttons to adjust the value.
- Press SET to move to the next time parameter (e.g., ON minutes, then OFF hours, etc.).
- Repeat step 3 and 4 until all parameters are set.
- Press SET one last time to confirm and exit the setting mode.
5. Calibration
If you suspect the temperature reading is inaccurate, you can calibrate the device:
- Unplug the thermostat from the power outlet.
- Plug the thermostat back into the power outlet.
- Immediately after plugging in, press and hold the MODE button for a few seconds until the screen indicates it is in calibration mode.
- Use the UP or DOWN buttons to adjust the temperature reading to match a known accurate thermometer.
- Press the SET button to confirm the calibration and exit the mode.
6. Maintenance
- Keep the device clean by wiping it with a dry, soft cloth. Do not use abrasive cleaners or immerse the device in water.
- Ensure the temperature probe is clean and free from debris for accurate readings.
- Avoid placing the device in areas with extreme humidity, dust, or direct sunlight.
- Regularly check the power cord and probe cable for any signs of damage.
7. Troubleshooting
7.1 Common Issues
- Inaccurate Temperature Reading:
- Ensure the probe is correctly placed and not affected by external factors (e.g., direct sunlight, drafts, or being too close to the appliance being controlled).
- Perform a temperature calibration as described in Section 5.
- Check the probe cable for damage. A damaged probe may require replacement.
- Appliance Not Turning ON/OFF:
- Verify that the 'Start Temperature' and 'Stop Temperature' are set correctly for either heating or cooling mode (refer to Section 4.1).
- Ensure the connected appliance is properly plugged into the thermostat outlet and is functioning independently.
- Check if the thermostat is in a timing mode (F01-F04) that might override temperature control. Switch back to temperature control mode if necessary.
- Confirm the appliance's power draw does not exceed the thermostat's maximum capacity (15A/1800W).
- Display Not Working:
- Ensure the thermostat is securely plugged into a live power outlet.
- If the screen is locked, unlock it according to the device's specific instructions (usually a combination of button presses).
- Try resetting the device by pressing the recessed Reset button.
