4. Setup Guide
4.1 Battery Installation
- Remote Sensors (F007TH):
- Remove the battery cover from the back of each remote sensor.
- Insert 2x AAA batteries into each sensor, observing polarity (+/-).
- Replace the battery cover, ensuring it is securely fastened to protect against elements.
- Main Console Unit (WS-08-X4):
- Open the battery compartment on the back of the main console.
- Insert 4x AAA batteries, observing polarity (+/-).
- Close the battery compartment. The console display should activate.
4.2 Setting Sensor Channels
Each remote sensor has dip switches inside the battery compartment to assign a unique channel (1-8) and select temperature units (°F or °C). It is crucial to assign a different channel to each sensor you intend to use.
- Open the battery compartment of a remote sensor.
- Locate the small dip switches (labeled 1-4).
- Refer to the chart printed on the sensor's back cover (or within the manual) to set the switches for your desired channel (e.g., Channel 1, Channel 2, etc.).
- Switch 4 typically controls the unit of measure (°F or °C).
- After setting, replace the battery cover.
4.3 Syncing Sensors with Console
Once batteries are installed and channels are set for all sensors, the main console will automatically begin searching for signals. If a sensor is not detected, use the sensor search mode:
- Press and hold the "CHANNEL" button on the main console for a few seconds until the console enters search mode.
- The console will scan for available sensors. Ensure sensors are within range.
- Once detected, the temperature and humidity readings for each channel will appear on the display.
4.4 Sensor Placement Guidelines
- Place remote sensors in shaded areas to avoid direct sunlight, which can cause inaccurate temperature readings.
- Ensure sensors are protected from direct rain and snow.
- Position sensors within the effective transmission range of the main console (up to 300 feet line of sight, 100 feet with obstructions).
- Avoid placing sensors near large metal objects or electrical appliances that may interfere with the wireless signal.
5. Operation
5.1 Understanding the Display

Figure 1: The Ambient Weather WS-08-X4 main console displaying indoor and multiple outdoor sensor readings, alongside the four included remote sensors.
The main console displays indoor temperature and humidity, along with readings from up to eight remote channels. Each channel shows temperature (°F or °C) and humidity (%). Comfort level and rate of change indicators may also be present.
5.2 Scroll Mode
In scroll mode, the console automatically cycles through and displays the indoor thermo-hygrometer readings and each detected remote channel at 5-second intervals. This allows for continuous monitoring of all active locations without manual intervention.
5.3 Min/Max Memory
The console records the minimum and maximum temperature and humidity values for both the indoor unit and each remote sensor. These values can be reset daily (at midnight) or manually.
- Press the "MIN/MAX" button to view the recorded minimum and maximum values.
- To manually reset the Min/Max values, press and hold the "MIN/MAX" button until the values clear.
5.4 Alarm Function
The device includes a time of day alarm. Consult the full user manual for detailed instructions on setting and managing alarms for specific temperature or humidity thresholds.
6. Maintenance
- Battery Replacement: Replace batteries in both the main console and remote sensors when the low battery indicator appears on the display. Use fresh, high-quality AAA batteries.
- Cleaning: Wipe the console and sensors with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Sensor Protection: Periodically check remote sensors for any signs of water ingress or damage. Ensure they remain in shaded, protected locations.
