4. Setup
4.1 Battery Installation
- Open the battery compartment on the back of each remote sensor and insert 2 x AAA batteries, observing polarity (+/-).
- Open the battery compartment on the back of the main display unit and insert 3 x AAA batteries, observing polarity (+/-).

4.2 Pairing Remote Sensors
Once batteries are installed in both the main unit and remote sensors, the main unit will automatically begin searching for RF signals from the sensors. The RF reception icon on the main unit will flash. The sensors should connect within 3 minutes. If a sensor does not connect, press the 'CHANNEL' button on the main unit to manually search for the sensor.

4.3 Sensor Placement
Place the remote sensors in desired locations. For accurate outdoor readings, ensure sensors are:
- Protected from direct sunlight and rain.
- Within the maximum transmission range of 100 meters (328 feet) in an open area. Walls and obstacles will reduce this range.
- Away from large metal objects or electrical appliances that may cause interference.

5. Operating Instructions
5.1 Display Information
The main unit's LCD displays the following information:
- Indoor Temperature and Humidity: Shown at the top of the display.
- Remote Sensor Readings: Channels 1, 2, and 3 display temperature and humidity from their respective sensors.
- Comfort Level: An icon (DRY, COMFORT, WET) indicates the current humidity comfort level.
- Temperature/Humidity Trend: Arrows indicate if readings are rising, stable, or falling.
- Low Battery Indicator: Appears when batteries in the main unit or a specific sensor are low.
5.2 MIN/MAX Record
Press the MIN/MAX button to view recorded maximum and minimum temperature and humidity values:
- Press once: Displays maximum recorded values (MAX).
- Press twice: Displays minimum recorded values (MIN).
- Press three times: Returns to current temperature and humidity values.
To clear the MIN/MAX records, press and hold the MIN/MAX button for 3 seconds while in MAX or MIN display mode. The records will reset to current values.
5.3 °C/°F Switch
Press the °C/°F button on the back of the main unit to switch the temperature display between Celsius (°C) and Fahrenheit (°F).
5.4 Backlight Function
Press the LIGHT button on the top of the main unit to activate the backlight. The backlight will stay on for approximately 10 seconds and then automatically turn off to conserve battery power.

6. Maintenance
- Clean the device with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Avoid exposing the main unit or remote sensors to extreme temperatures, direct sunlight, or excessive moisture.
- Replace batteries promptly when the low battery indicator appears to ensure continuous and accurate readings.
- If the device will not be used for an extended period, remove the batteries to prevent leakage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No remote sensor signal (dashes on display) | 1. Batteries are low or incorrectly installed. 2. Sensor is out of range or experiencing interference. 3. Sensor channel not correctly set. | 1. Replace batteries in the sensor and/or main unit. Ensure correct polarity. 2. Move sensor closer to the main unit. Avoid large metal objects or electronics. Try different locations. 3. Press the 'CHANNEL' button on the main unit to manually search for the sensor. Ensure the sensor's channel switch matches the selected channel on the main unit. |
| Inaccurate temperature/humidity readings | 1. Sensor exposed to direct sunlight or rain. 2. Sensor placed near heat sources or vents. | 1. Relocate the sensor to a shaded, dry area. Ensure proper ventilation around the sensor. 2. Move the sensor away from any heat or cold sources. |
| Display is dim or blank | Low batteries in the main unit. | Replace the 3 x AAA batteries in the main unit. |
