Changing the batteries
If you have opted for a wireless control, the battery
status of the individual room units is displayed in the
app. If the service life of the batteries comes to an end,
this will be displayed so that you can change the
batteries. Please use two batteries type AAA 1.5 V
Micro LR03. Rechargeable batteries may not be used.
If you have a mixed system, you will see a mains plug
instead of a battery.
Replace the batteries if the fault message “low
battery” is displayed.
To do so, open the housing of the NEA SMART 2.0
Room unit (see Fig. 8-1) with a screwdriver (recom-
