1.1.1. Measuring accuracy
Follow the instructions in chapter Installation position to avoid sources of interference
and to ensure the specified accuracy of the sensor.
When measuring temperature, the self-heating of the device is considered by the
electronics. The heating is compensated by reducing the measured temperture by the
self-heating of 0.7°C. The indicated indoor temperature measured value approches the
