2.2.2 Main function
The remote control sends data, such as
the current room temperature, to the radio
receiver unit. The remote control receives
data from the radio receiver unit that you
can read on the display. On the remote
control you can, for example, set the op-
erating mode, the time periods or the tem-
perature.

Ensure that the room air can circulate
freely around the remote control, and

▶
Ensure that all radiator valves in the
room where the remote control is fitted
are fully open.
