Vaillant VRT 350 Operating Instructions Manual page 20

One room thermometer constantly shows a temperature that
is one degree higher than the current room temperature on
the controller display. With the Room temperature func-
tion, you can offset the temperature difference in the con-
troller display by setting a correction value of +1 K (1 K cor-
responds to 1 °C). K (Kelvin) is a unit for the temperature dif-
ference. Inputting a correction value affects the room temper-
ature compensator.
