7 Troubleshooting
7.1
Aligning a temperature deviation
A deviation between the temperature display of the
bathroom radiator and the display on a thermometer
is not unusual and can be aligned if this is more than
+/- 0.5 °C.
To compare the displayed temperature of the device
with that of a thermometer,
ensure that the notes in the operating instruc-
tions, in particular the positioning and minimum
distances, are complied with,
close all external opening and internal doors of the
heated room,
position the thermometer in the centre of the
room at a height of 1.2 m (do not place on a piece
of furniture),
set Comfort mode on the radiator and select a set
value between 17 °C and 23 °C,
wait approx. 6 hours until the heating in the room
has stabilised and avoid walking around in the
room during this time,
ensure that the temperature displayed on the ra-
diator and the temperature on the thermometer
are stable.
