Setting the weekly program
The weekly program allows you to set up to 3 separate heating periods (7 switching times) for each day of the week. Pro-
gramming is performed in relation to the selected days, for which temperatures must be stored for a period from 00:00 to
23:59.
• Press and hold down the menu button for more than 3 seconds.
• “Pro” will appear on the display.
• Confirm with OK.
• “dAy” will appear on the display. The setting wheel can be used to select an individual day of the
week, all working days, the weekend or the entire week (example shows working days selected).
• Confirm with OK.
• Use the setting wheel to set the first time segment (example shows 0:00 to 6:00).
• Then, select the required temperature for the selected time segment (example shows 17.0°C).
• Confirm with OK.
• Keep repeating this process until you have finished storing temperatures for the period from
0:00 to 23:59.
In Auto mode, the temperature can be modified at any time via the setting wheel. The modified temperature will then be
retained until the next program changeover.
Weekly program: Examples
The energy-saving controller allows you to store up to 3 heating periods (7 switching times) with individual temperature
settings for each day of the week. The factory setting consists of two heating phases (from 6:00 until 9:00 and from 17:00 until
23:00 respectively) for every single day of the week:
from 00:00 to 06:00
17.0 °C
from 06:00 to 09:00
21.0 °C
from 09:00 to 17:00
17.0 °C
from 17:00 to 23:00
21.0 °C
from 23:00 to 23:59
17.0 °C
To represent the switching periods, the display shows bars for every other switching interval. In this example, no bars are
shown for the interval from 0:00 to 6:00. Bars are only shown on the display for the intervals from 6:00 to 9:00 and from 17:00
to 23:00.
If a room also needs to be heated at around noon, the corresponding program might look like this:
Monday bis Sunday
from 00:00 to 06:00
16.0 °C
from 06:00 to 09:00
22.0 °C
from 09:00 to 12:00
17.0 °C
from 12:00 to 14:00
20.0 °C
from 14:00 to 17:30
17.0 °C
from 17:30 to 23:30
21.0 °C
from 23:30 to 23:59
16.0 °C
If you have a home office and only want it to be heated during the day on working days, you can program the following
times:
Monday bis Sunday
from 00:00 to 08:30
17.0 °C
from 08:30 to 17:00
