- Indoor Temperature & Humidity: Displays current conditions at the main unit's location.
- Sensor 1 Temperature & Humidity: Shows readings from the first wireless sensor (green zone).
- Sensor 2 Temperature & Humidity: Shows readings from the second wireless sensor (blue zone).
- Time & Date: Current time and calendar display.
- Max/Min Records: Tracks highest and lowest temperature/humidity for each channel.
- Alarm Indicators: Visual alerts for temperature deviations.
Setup
Battery Installation:
- Main Unit: Open the battery compartment on the back. Insert 3 x AAA batteries (not included), ensuring correct polarity (+/-).
- Wireless Sensors: Open the battery compartment on each sensor. Insert 2 x AA batteries (not included) into each sensor, observing correct polarity.
Note: The main unit can also be powered via the included USB cable. When powered by USB, the backlight remains on and offers three brightness levels.
Sensor Synchronization:
After installing batteries in both the main unit and sensors, the sensors will automatically attempt to synchronize with the main unit. This process may take a few moments. Ensure sensors are within range of the main unit during initial setup.
Operating Instructions
Basic Display:
The main unit displays indoor temperature and humidity, along with readings from Sensor 1 and Sensor 2. Each sensor's data is presented in a distinct color zone (green for Sensor 1, blue for Sensor 2) for easy identification.
Temperature Unit Selection (℃/℉):
Press the MODE button to cycle through display modes. To change the temperature unit between Celsius (℃) and Fahrenheit (℉), locate the dedicated button (often labeled ℃/℉ or integrated with another button like +/-) and press it.
Max/Min Records:
The device records maximum and minimum temperature and humidity values for the past 24 hours or since the last reset. Briefly press the +/- button to switch between 24-hour and all-time record modes. To clear the records, press and hold the +/- button.
Backlight Control:
- Battery Power: The backlight activates for 10 seconds when any button is pressed.
- USB Power: The backlight remains continuously on. Press the backlight button (if available) or a specific button combination to adjust between three brightness levels.

Temperature Alarm Function
The thermometer features an adjustable alarm function for both wireless sensors. You can set specific maximum and minimum temperature thresholds.

Setting the Alarm:
- Press the CH1 or CH2 button to select the sensor channel you wish to configure.
- Press and hold the ALERT button (or a similar button, refer to the specific manual for exact button labels) until the alarm temperature settings begin to flash.
- Use the +/- buttons to adjust the desired maximum and minimum temperature thresholds.
- Press the ALERT button again to confirm and save the settings.
If the temperature in a monitored zone exceeds or falls below the set thresholds, the main unit will emit an audible alarm for two minutes. Press the -/RF button to view pre-set alarm temperatures.
Installation
The main unit and wireless sensors offer multiple installation options for convenience.

Main Unit Placement:
- Stand: Use the integrated kickstand on the back to place the unit on a countertop or shelf.
- Magnetic Attachment: Attach the provided magnetic plate to the back of the main unit and then secure it to any metallic surface, such as a refrigerator door.
- Wall Mount: Utilize the hanging hole on the back to mount the unit on a wall using a screw or hook (not included).
Wireless Sensor Placement:

- Place the wireless sensors inside your refrigerator, freezer, or any other area you wish to monitor.
- Ensure the sensors are placed vertically as indicated in the instructions for optimal performance.
- The maximum transmission distance is approximately 100 meters (328 feet) in open areas. Walls and obstacles may reduce this range.
Maintenance
- Cleaning: Wipe the main unit and sensors with a soft, damp cloth. Do not use abrasive cleaners or immerse in water.
- Battery Replacement: When the low battery icon appears on the display, replace the batteries promptly. For the main unit, use 3 x AAA batteries. For each wireless sensor, use 2 x AA batteries.
- Storage: If not in use for an extended period, remove all batteries to prevent leakage and store the device in a cool, dry place.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit. | Batteries are dead or incorrectly installed. | Replace batteries (3xAAA) or check polarity. Connect USB power. |
| Sensor readings not appearing. | Sensor batteries are dead, sensor is out of range, or not synchronized. | Replace sensor batteries (2xAA). Move sensor closer to the main unit. Re-synchronize by removing and reinserting batteries in both units. |
| Inaccurate temperature/humidity. | Sensor placement, interference, or calibration issue. | Ensure sensors are not near heat sources or vents. Allow time for readings to stabilize. If persistent, contact support. |
| Alarm not sounding. | Alarm thresholds not set or alarm function is off. | Verify alarm settings and ensure the alarm icon is active on the display. |
| Settings reset after battery change. | This model does not retain settings without continuous power. | Re-enter time, date, and alarm settings after each battery replacement. Consider using USB power for the main unit to retain settings. |
