6.10 The accommodation is always too hot
Reduce the low end temperature of the heating curve by the
number of degrees the room temperature exceeds a comfortable
temperature.
6.11 The accommodation is too cold in winter
If the temperature of your home in spring and autumn is OK,
but the rooms do not become warm enough when the outside
temperature drops sharply (-10°C), increase the gradient of the
heating curve. This means it will become slightly warmer in spring
and autumn as well. You should therefore slightly lower the low
end temperature.
6.12 The accommodation is too hot in winter
If your heating system produces too much heat when temperatures
drop sharply, reduce the gradient of the heating curve. This means
your home will become slightly colder in spring and autumn as
well. You should therefore slightly raise the low end temperature.
6.13 The accommodation is too cold in spring and
autumn
One possible cause may be that summer mode is enabled and
that central heating is off, as a result. Switch the appliance to
manual mode or ask your authorised contractor to change the
standard settings.
If the room temperature in spring and autumn (10°C) is too low,
reduce the gradient and increase the low end temperature.
6.14 The accommodation is too hot in spring and
autumn
f Increase the heating curve gradient slightly and reduce its
low end slightly.
6.15 The accommodation is too hot in summer

f Select a higher fan stage.
6.17 The air in winter is too dry
f Select fan stage 1.
f Activate the humidity correction.
