How does the comfort indicator work?
The screen displays a clear comfort icon when both temperature (18–28°C / 64.4–82.4°F) and humidity (40–65% RH) are within the ideal range. If either value goes beyond these limits, the icon changes to notify you that conditions may need adjustment.
What type of batteries should I use, and are there any usage tips?
Please use new alkaline batteries only. Do not mix old and new batteries. We recommend completing Wi-Fi/Bluetooth setup right after installing the batteries to avoid unnecessary power consumption.
How often does the device update its readings?
If temperature changes by =0.5°C or humidity by =5%, readings refresh every 2 minutes. Under stable conditions, updates occur every hour to conserve battery.
Why does the screen sometimes lock the readings after I press the backlight button?
To ensure readability, the values are locked for 2 minutes after the backlight is activated. If the button is pressed again within 2 minutes, the lock can extend up to 15 minutes maximum.
What do the Max/Min values on the screen represent?
The displayed Max/Min temperature and humidity are 24-hour averages. If the device is restarted, it will begin recalculating these values based on new data.
