4. Setup
4.1 Battery Installation
- Remote Sensors: Open the battery compartment cover on each remote sensor. Insert 2x AA batteries into each sensor, observing the correct polarity (+/-). Select a unique channel (1, 2, or 3) for each sensor using the internal switch. Close the battery compartment.
- Main Display Unit: Open the battery compartment cover on the back of the main unit. Insert 3x AAA batteries, observing the correct polarity (+/-). Close the battery compartment. Alternatively, connect the provided USB cable to the USB-C input on the main unit and plug the other end into a 5V USB power adapter (not included) for continuous power.
4.2 Initial Pairing
Once batteries are installed in both the sensors and the main unit, the main unit will automatically begin searching for signals from the remote sensors. This process may take a few minutes. Ensure the sensors are within range of the main unit during initial setup.
- If a sensor does not connect, press and hold the 'CH' button on the main unit for 3 seconds to initiate a manual search.
- Ensure each remote sensor is set to a different channel (1, 2, or 3) to avoid interference.
5. Operating Instructions
5.1 Display Features

The 4.4-inch LCD display provides the following information:
- Indoor Temperature & Humidity: Displayed at the top.
- Outdoor Temperature & Humidity: Displayed for each connected remote sensor (Channels 1, 2, 3).
- Comfort Level Indicator: An icon indicating the current comfort level (Humid, Comfortable, Dry).
- Temperature & Humidity Trend Indicators: Arrows showing if values are rising, falling, or stable.
- Frost Point Warning: An icon may appear if outdoor temperature approaches freezing.
- Low Battery Indicator: Appears when batteries need replacement.
5.2 Temperature Unit Selection (℃/℉)
Image: Switching between Celsius and Fahrenheit temperature units.
To switch between Celsius (℃) and Fahrenheit (℉), press the 'C/F' button located on the side of the main unit.
5.3 MAX/MIN Records

The comfort level indicator provides a quick assessment of the environment based on humidity:
- Humid: Humidity > 70%
- Comfortable: Humidity 40% - 70%
- Dry: Humidity < 40%
5.5 Trend Indicators
Image: Temperature and humidity trend indicators.
Arrows next to the temperature and humidity readings indicate the trend over the last hour:
- Up Arrow (↑): Increasing (Temp +1℃, Humidity +5% RH)
- Down Arrow (↓): Decreasing (Temp -1℃, Humidity -5% RH)
- Horizontal Arrow (→): Stable (Temp within 1℃, Humidity within 5% RH)
5.6 Alarm Settings

The display backlight can be adjusted:
- USB Power Mode: When powered by the USB cable, press the backlight button (light bulb icon) to cycle through three brightness levels: High, Low, and Off. The backlight will remain on continuously.
- Battery Power Mode: When powered by batteries only, pressing the backlight button will illuminate the screen for 10 seconds before automatically turning off to conserve power.
6. Sensor Placement and Installation
Proper placement of the remote sensors is crucial for accurate readings and optimal wireless transmission.
Image: Example of multi-sensor placement around a home.
- Range: The sensors have a transmission range of up to 100 meters (328 feet) in open areas. Walls, metal structures, and other electronic devices can reduce this range.
- Protection: To ensure accuracy and durability, protect the remote sensors from direct sunlight and rain.
Image: Guidelines for correct outdoor sensor installation.
- Ideal Locations: Place sensors under an overhang, porch, or in a shaded, well-ventilated area.
- Mounting: Use the integrated wall mount hole to secure the sensors to a vertical surface.
7. Maintenance
- Battery Replacement: Replace batteries in the main unit and remote sensors when the low battery indicator appears on the display. Always replace all batteries in a unit at the same time.
- Cleaning: Clean the display unit and sensors with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Storage: If storing the device for an extended period, remove all batteries to prevent leakage.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit | Batteries are dead or incorrectly inserted; USB power not connected. | Check battery polarity and replace if necessary. Ensure USB cable is securely connected to a working power source. |
| Outdoor sensor data not displayed | Sensor out of range; low sensor battery; incorrect channel setting; interference. | Move sensor closer to the main unit. Replace sensor batteries. Ensure sensor channel matches the selected channel on the main unit. Press and hold 'CH' button on main unit to re-scan. Avoid placing near large metal objects or other electronics. |
| Inaccurate readings | Sensor exposed to direct sunlight or rain; sensor placed near heat/cold sources. | Relocate sensor to a shaded, protected, and well-ventilated area away from extreme temperature sources. |
| Backlight not staying on | Main unit is running on battery power. | Connect the main unit to a USB power source for continuous backlight. |
