Setup
1. Battery Installation
The main display unit requires 2 AA batteries, and each remote sensor requires 2 AAA batteries. Batteries are not included.
- Open the battery compartment on the back of the main display unit.
- Insert 2 AA batteries, observing the correct polarity (+/-).
- Close the battery compartment.
- For each remote sensor, open the battery compartment.
- Insert 2 AAA batteries, observing the correct polarity (+/-).
- Close the battery compartment.

2. Sensor Placement and Pairing
Place the remote sensors in desired outdoor or indoor locations within the 60-meter (200 feet) transmission range. Avoid direct sunlight and rain for outdoor sensors, as they are IPX4 splash-proof but not fully waterproof.
- Ensure all batteries are installed correctly in both the main unit and the remote sensors.
- The main unit will automatically search for signals from the remote sensors. This may take a few minutes.
- If a sensor does not connect, press the "CH/▲" button on the main unit to cycle through channels or press the reset button on the sensor.
- The main unit can display readings from up to three remote sensors (CH1, CH2, CH3) in addition to its internal sensor (IN).

4. Comfort Level Indicator
The display includes a comfort level indicator (face symbol) to quickly assess indoor conditions:
- DRY: Humidity < 40%
- COMFORT (COM): 40% ≤ Humidity ≤ 70% AND 20°C ≤ Temperature ≤ 28°C (68°F ≤ Temperature ≤ 82.4°F)
- WET: Humidity > 70%
Image: The comfort display feature, showing different face symbols for DRY (unhappy face, humidity < 40%), COMFORT (happy face, 40% ≤ humidity < 70% and 68°F ≤ temperature < 82.4°F), and WET (sad face, humidity > 70%). The main unit shows a "COM" indicator.
Maintenance
1. Cleaning
Wipe the display unit and sensors with a soft, damp cloth. Do not use abrasive cleaners or solvents.
