Standby and main screen
If you do not operate the thermostat for a while, it automatically
switches to standby mode. While in standby mode, touching any button
will display the main screen.
Pressing middle button 8 on the main screen will take you to the
main menu. Press right and left buttons (7/9) to change the
temperature.
Note
If the thermostat is in "Week schedule" mode:
When you change the set temperature directly on the screen, you
will be asked if you wish to add this new set temperature to the week
schedule. In this way, the thermostat can utilise your behaviour to
program the weekly schedule automatically. If you select "No", the
set temperature will be used just as a one-off setting instead. See also
chapter "Week schedule".
