can be used when 24 hour heating is required or
for constantly lowering the temperature when
going on holiday. An unbroken clock ring indi-
cates constant temperature.
Fixed periods with lowering of temperature
By using of the built-in timer you can set up
xed periods for each day of the week where the
temperature is lowered (e.g. at night and when
you are at work). is means automatic switch-
ing between economy and comfort temperature.
Read more about how to set periods with lower-
ing of temperature on page 12.
When the timer is on, it is indicated by a timer
symbol in the form of a clock (and a clock ring if
periods with lowering of temperature have been
selected).
