c) Mounting/Installing the indoor sensor
The sensor can be used via the suspension eye "A" as wall device or can

When drilling or tightening screws, be careful not to damage
any power supply lines, gas or water pipes, as there may be
life-threatening danger involved!

They must be replaced when in the display of the corresponding display
device the battery symbol for the sensor appears.
