Image Description: This image compares the use of the built-in sensor versus an external sensor.
The "Built-in Sensor" section shows a thermostat on a wall in a small room, suitable for even temperature distribution.
The "External Sensor" section shows a thermostat with a connected 3-meter external sensor cable in a larger room, suitable for uneven temperature distribution.
  • Built-in Sensor: Ideal for smaller rooms with uniform temperature distribution.
  • External Sensor: Use the provided 3-meter external sensor cable for larger rooms or areas where temperature distribution might be uneven.

Accessing Advanced Options:

To access advanced settings, follow these steps:

  • With the device turned off, press and hold the Power button and the Mode (M) button simultaneously for five seconds.
  • Once in the advanced options mode, press the Mode (M) button to cycle through different options.
  • Use the Up and Down arrow buttons to adjust parameters for the selected option.
  • To exit the advanced options mode, press the Power button.

Within these options, you can configure:

  • Temperature Calibration: Correct the thermostat's temperature display if it differs from the actual room temperature.
  • Child Safety Lock: Prevent unintended changes to settings.
  • Frost Protection: Automatically activate heating if the temperature drops below a set threshold to prevent freezing.
  • Power Failure Data Backup: Ensures your settings are retained after a power outage.
  • Backlight On/Off: Control the display backlight.
  • Temperature Scale Change: Switch between Celsius (°C) and Fahrenheit (°F).

Maintenance

To ensure the longevity and optimal performance of your CNBINGO Digital Room Thermostat, follow these simple maintenance guidelines:

  • Cleaning: Gently wipe the thermostat's surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the display or casing.
