therefore reacts to the fluctuations of the room temperat-
ure and constantly controls the room temperature to the
temperature that you have set.
The controller is powered by batteries. Data transmission
between the controller and the radio receiver unit takes
place via radio communication. Data transmission between
the radio receiver unit and the boiler takes place via an
eBUS interface, which also provides the power supply for
the radio receiver unit.
Data communication and the power supply for the control-

equipped with the Vaillant diagnostics software and the
Vaillant Internet communication system for remote dia-
gnostics and remote settings.

the domestic hot water cylinder until it reaches the set tem-
perature. You can set a time period during which hot water
should be available in the domestic hot water cylinder.
