Getting started

4.1 Power supply
The device uses a Li-Ion rechargeable battery of 7.4 V/3400 mAh that has to be charged with the 12 V/1.5 A charger provided. The charging process can increase the temperature inside the device and affect the temperature measurement.
The battery life depends on the configuration of the different sensors. It is recommended to set the same sampling time value for measuring the temperature, humidity, and pressure and a higher sampling time value for the CO2 measurement. The recommended configurations and the estimated battery lives are:

Note:
The battery life can vary depending on the ambient conditions.

The device can also be used when connected to mains power via the power charger.
4.2 Preparation
The device is designed to be mounted on the wall. For this purpose, it has two holes for screws and you can use screws with a diameter of 4 mm. To uncover the holes, pull the small tabs through the slits on the front panel of the device. In the image, the drill template can be seen.
