1. Introduction
Thank you for choosing the PROTMEX Wireless Weather Station. This device provides comprehensive indoor and outdoor environmental data, including temperature, humidity, barometric pressure, and weather forecasts. It also features a clock with alarm functions and a convenient USB charging port.
2. Package Contents
- 1 x PROTMEX Weather Station Main Unit (Indoor Receiver)
- 1 x Wireless Remote Sensor (Additional sensors may be purchased separately for models PT20B and PT20C)
- 1 x DC 5V Power Adapter (for Main Unit)
- 1 x User Manual (this document)
3. Initial Setup
3.1 Powering the Devices
- Remote Sensor: Open the battery compartment on the back of the remote sensor. Insert 2 x AAA 1.5V batteries (not included), ensuring correct polarity. Close the battery compartment.
- Main Unit (Indoor Receiver):
- Option 1 (Power Adapter): Connect the DC 5V power adapter to the "DC 5V" input socket on the back of the main unit and plug it into a wall outlet.
- Option 2 (Batteries): Open the battery compartment on the back of the main unit. Insert 3 x AAA 1.5V batteries (not included), ensuring correct polarity. Close the battery compartment. Note: Using batteries alone may limit backlight functionality.
3.2 Pairing the Remote Sensor
Once both units are powered, the main unit will automatically search for the remote sensor's signal. This may take a few minutes. The outdoor temperature and humidity readings will appear on the main unit's display once connected.
If the outdoor readings do not appear, press and hold the "CH" button on the main unit to manually initiate a search for the sensor. Ensure the remote sensor is within the 60-meter (200 ft) line-of-sight wireless transmission range.
3.3 Initial Time and Date Setting
The weather station features a Radio Controlled Clock (RCC) via DCF signal. It will attempt to synchronize the time automatically. If manual adjustment is needed or preferred:
- Press the "SET" button to enter time setting mode.
- Use the "+" and "-" buttons to adjust values.
- Press "SET" again to confirm each setting and move to the next (e.g., 12/24 hour format, hour, minute, year, month, day).

- Comfort Level: An emoji icon indicates the indoor comfort level based on temperature and humidity.
- Data Trend: Trend arrows indicate whether temperature, humidity, and air pressure are rising, falling, or remaining steady.
- Temperature Alerts: Set high and low temperature alert values for indoor and outdoor readings. An icon will flash and an alert sound will activate when the temperature reaches the set value.
- Moon Phase: Displays the current moon phase.
- Frost Warning: A snowflake icon will appear when the outdoor temperature is between -2°C and 3°C (28.4°F and 37.4°F).
4.3 USB Charging Port
The main unit includes a USB output port (5V) that can be used to charge other devices like mobile phones, MP3 players, or tablets when the weather station is powered by its DC 5V adapter. A charging status indicator will be visible on the display.
5. Maintenance
- Cleaning: Wipe the display and unit surfaces with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace batteries in both the main unit and remote sensor when the low battery indicator appears on the display. Ensure correct polarity when inserting new batteries.
- Placement: For optimal performance, place the remote sensor in a shaded, dry location outdoors, protected from direct sunlight and rain. Ensure it is within the wireless range of the main unit.
6. Troubleshooting
- No Outdoor Reading:
- Ensure batteries are correctly installed in the remote sensor and main unit.
- Press and hold the "CH" button on the main unit to re-establish connection.
- Move the remote sensor closer to the main unit, ensuring it's within range and free from obstructions.
- Check for interference from other electronic devices.
- Incorrect Time/Date:
- Ensure the unit is receiving the DCF signal (if applicable to your region).
- Manually set the time and date using the "SET" and "+/-" buttons.
- Display is Dim/Off:
- Ensure the main unit is powered by the DC 5V adapter for full backlight functionality.
- Short press the "SNOOZE/LIGHT" button to adjust brightness. Long press to turn it off/on.
