place where it is not exposed to sunlight or draft from
door openings.
ƒEqually distant and >2cm from two heating cables.

3.2 Forecast
The forecast feature is used when you switch between
economy temperature and comfort temperature. If forecast
is turned on, heating will start so that the requested tem-
perature is reached at the specified time.
For example, if your comfort temperature is set to 22°C and
the comfort period starts at 6.00 o'clock am, heating will
start before 6 o'clock so that your room temperature will be
22°C at 6 o'clock. If forecast is turned off, heating will not
start until 6 o'clock and it will take a while to reach a room
temperature of 22°C.
