The WH0310 Wireless Weather Station with Multi-channel Temperature Sensor is a device designed to monitor indoor temperature, humidity, and barometric pressure. It also supports up to three temperature sensors (additional two sensors sold separately) for monitoring multiple locations.
Function Description:
The weather station consists of a display console and a multi-channel thermometer sensor. The display console shows indoor temperature, humidity, and barometric pressure. It also displays weather forecasts, pressure changing trends, 24-hour/7-day history graphs for barometric pressure, and outdoor/multi-channel temperature readings along with their 24-hour high/low records. The remote sensor transmits temperature data wirelessly to the console.

Usage Features:
Getting Started:
The power-up sequence requires inserting batteries into the remote transmitter(s) first, then the display console.
- Thermometer Sensor Setup:
- Remove the battery door by sliding it down.
- Set the RF sensor channel (1, 2, or 3).
- Insert one AA battery.
- The remote sensor LED indicator will light for 4 seconds, then flash once every 60 seconds when transmitting data.
- Close the battery door.
- For additional remote transmitters, repeat the process, ensuring each is on a different channel.
- Display Console Setup:
- Place the remote thermometer(s) 5 to 10 feet away from the display console for optimal reception.
- Remove the battery door on the back of the display.
- Insert one AA (alkaline, lithium, or rechargeable) battery.
- All LCD segments will light up briefly to verify proper operation.
- Replace the battery door and fold out the desk stand to place the console upright.
- The console will instantly display indoor temperature and humidity. Remote temperature will update within a few minutes. The reception search icon will flash during search mode.
Console Operation:
The console features five buttons: '+' and 'CH' (left), '-' and 'MODE' (right), and 'LIGHT' (top). Any program mode can be exited by pressing the 'LIGHT' button or by waiting for the 30-second time-out.
- ABS/REL Barometer Display: In normal mode, press the 'MODE' button once to switch between absolute (ABS) and relative (REL) barometer display.
- Setting Mode: Hold the 'MODE' button for 2 seconds to enter setting mode.
- Temperature Display Unit: Set to C/F.
- Barometer Display Unit: Set to hPa/mmHg/inHg.
- REL Barometric Pressure Calibration: Range 300.0-1200.0 hPa / 8.86-35.44 inHg / 225.0-900.1 mmHg. Calibration instructions are available at http://www.ecowitt.com/news/102.html.
- Use the 'MODE' button to navigate settings, and '+' or '-' buttons to change values. Press 'LIGHT' to return to normal mode.
- Pressure Tendency Indicator: Updates every 60 seconds. An upward direction indicates improving weather.
- 24H/7days History Graph: Switch between 24-hour and 7-day pressure history graphs using the '+' button.
- Weather Forecast Algorithm: Compares the past 24-hour average pressure against the past 30-day average pressure.
>=4hpa: Sunny-0.5hpa to 3.5hpa: Partly cloudy-3.5hpa to -1hpa: Cloudy <=-4hpa: Rainy- A sudden pressure decrease will trigger a flashing "Rainy" display, indicating an approaching storm.
- RF Channels Setting and Sensor Resynchronization:
- The default display mode for outdoor/multi-channel sensor data is Cycle Mode, indicated by an arrow icon with the channel number. Different channel sensor data will toggle on the LCD.
- Press 'CH' once to exit cycle mode and display the current channel sensor data continuously.
- The cycle sequence is CH1 – CH2 – CH3 – Cycle Mode.
- If the remote sensor signal is lost, dashes '--' will display.
- In cycle mode, hold the 'CH' button for 2 seconds to re-register all channel sensors.
- In non-cycle mode, hold the 'CH' button for 2 seconds to re-register the current channel sensor.
- If only one multi-channel temperature sensor is purchased, the other two channels will display '--'.
- Cycle mode can be canceled to display only the current channel data.
- High Low Record:
- Check latest 24 hours High/Low record: In normal mode, the console displays the latest 24-hour high/low record for outdoor/multi-channel temperature.
- Check history High/Low record: In normal mode, press the '-' button (the 24HR icon will disappear) to check the history high/low records for outdoor/multi-channel temperature since power-on or last clear.
- In cycle mode, hold the '-' button for 2 seconds to clear the high/low record for all channels.
- In non-cycle mode, hold the '-' button for 2 seconds to clear the high/low record for the current channel.
Maintenance Features:
Wireless Communication Best Practices:
To ensure proper communication and minimize interference, distance, walls, and metal barriers:
- Electro-Magnetic Interference (EMI): Keep the console several feet away from computer monitors and TVs.
- Radio Frequency Interference (RFI): If communication is intermittent with other 433 MHz devices, try turning them off for troubleshooting. Relocate transmitters or receivers if necessary.
- Line of Sight Rating: The device is rated for 300 feet line of sight (no interference, barriers, or walls). Typically, 100 feet maximum is achieved in most real-world installations with barriers or walls.
- Metal Barriers: Radio frequency will not pass through metal barriers like aluminum siding. If metal siding is present, align the remote and console through a window for a clear line of sight.
- Sensor Mounting: Mount the remote sensor on a vertical surface, such as a wall, in a shaded area. Do not lay the sensor flat. Direct sunlight and radiant heat sources can cause inaccurate temperature readings. Although weather-resistant, mounting in a well-protected area (e.g., under an eve) is recommended.
The product comes with a 1-year limited warranty against manufacturing defects in materials and workmanship.
