Product Overview
Main Display Unit
The main unit features a color LCD screen displaying indoor temperature and humidity, as well as temperatures from the two remote sensors. It has buttons for backlight control, ℃/℉ switching, and alarm settings.
Wireless Remote Sensors
The two compact wireless sensors are designed to be placed in refrigerators, freezers, or other areas you wish to monitor. They transmit temperature data to the main unit.

Setup
- Insert Batteries: Open the battery compartment on the back of the main unit and each remote sensor. Insert 2x AAA batteries into the main unit and 2x AAA batteries into each sensor, ensuring correct polarity (+/-). Batteries are not included.
- Power On: The main unit will automatically power on once batteries are inserted or USB power is connected. The sensors will also power on.
- Pairing Sensors: The main unit will automatically search for and connect to the remote sensors. Ensure sensors are within range during initial setup. The channel indicators (CH1, CH2) on the main unit will display the sensor temperatures once connected. If a sensor does not connect, try re-inserting its batteries or moving it closer to the main unit.
Operating Instructions
Switching Temperature Units (℃/℉)
Long press the '℃/℉' button (often combined with the backlight button) on the main unit to switch between Celsius and Fahrenheit display modes.
Viewing and Clearing MAX/MIN Records
- The main unit automatically records the maximum and minimum temperatures for the indoor unit and each sensor.
- Press the 'MEM' button to cycle through current, maximum (MAX), and minimum (MIN) temperature readings.
- To clear the MAX/MIN records, long press the 'MEM' button while MAX or MIN values are displayed. The records will reset to current temperatures.
Temperature Alarm Function
The thermometer allows you to set high and low temperature alarms for each remote sensor (CH1, CH2).
- Press the 'ALERT' button to enter alarm setting mode. The alarm icon will flash.
- Use the '+' and '-' buttons to adjust the desired high temperature limit for CH1. Press 'ALERT' again to confirm.
- Repeat the process to set the low temperature limit for CH1, then high and low limits for CH2.
- Once all limits are set, press 'ALERT' one last time to exit alarm setting mode.
- If the temperature from a sensor exceeds the set limits, the main unit will emit an audible alarm and the screen backlight will turn red. The alarm will sound every 20 seconds.
- To silence the alarm, press any button. The red backlight will remain until the temperature returns to within the set range.

Backlight and Power Modes
- USB Power: When the main unit is connected via the USB cable, the backlight will remain continuously on for easy viewing.
- Battery Power: When powered by 2x AAA batteries, the backlight will automatically turn off after 8 seconds of inactivity to conserve battery life. Short press the backlight button to temporarily activate it.

Installation
Main Display Unit Placement
The main unit offers multiple installation options:
- Magnetic Attachment: Use the integrated magnets on the back to attach it to a refrigerator door or any metallic surface.
- Wall Hanging: Utilize the hanging hole to mount it on a wall hook.
- Tabletop Stand: Deploy the foldable stand on the back to place it on a flat surface like a kitchen counter or desk.
Remote Sensor Placement
Place the remote sensors in the desired monitoring locations, such as inside a refrigerator, freezer, wine cellar, or outdoor area. Each sensor has a hanging hole for convenient placement. Ensure sensors are not exposed to direct sunlight or rain to prolong their lifespan.

Maintenance
- Cleaning: Wipe the main unit and sensors with a soft, damp cloth. Do not use abrasive cleaners or immerse the devices in water.
- Battery Replacement: Replace batteries in the main unit and sensors when the low battery indicator appears on the display. Ensure to use fresh AAA batteries and dispose of old batteries responsibly.
- Storage: If storing the device for an extended period, remove all batteries to prevent leakage and damage. Store in a cool, dry place.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit | Dead or incorrectly inserted batteries; No USB power. | Check battery polarity, replace batteries, or connect USB power. |
| Sensor temperature not displayed or '---' shown | Sensor out of range; Dead sensor batteries; Pairing issue. | Move sensor closer to main unit; Replace sensor batteries; Re-insert sensor batteries to force re-pairing. |
| Temperature alarm not working | Alarm not enabled; Alarm limits set incorrectly. | Ensure alarm is activated in settings; Verify high/low temperature limits are appropriate. |
| Inaccurate temperature readings | Sensor exposed to direct heat/cold source; Sensor placed too close to a wall/obstruction. | Relocate sensor to a more representative area; Ensure proper air circulation around the sensor. |
