HEATING CIRCUIT 1
In this example, only one switching time pair has so far been
programmed. For switching time pairs 2 and 3, short dashes are
displayed instead of times. These switching time pairs are still
empty. Select one of the free switching time pairs with “OK” to
reach the area where you can set the associated start and end
time. Pressing “OK” brings up the display shown below. Set the
required time.

SETTINGS
Times can be entered in intervals of 15 minutes. You can set 16:30
or 16:45 h, but not 16:37 h. Confirm your entry with OK.
Periods around midnight
Assume, for example, you want heating mode to be enabled from
22:00 h for four hours every Wednesday evening. This means the
period does not expire until the next day, Thursday, at 02:00h.
However, since the day ends at 00:00 h, two switching time pairs
are necessary for the required program. First, program the period
22:00 to 00:00h for Wednesday, then 00:00 to 02:00h for Thursday.
Deleting a switching times pair
Select the pair of switching times you want to delete. Go to the
start time change. Turn the scroll wheel to reduce the time. If you
reach 00:00 and continue to make a rotation, the pair of switch-
ing times is removed. The previously shown display appears, i.e.
dashes instead of numbers. Confirm again with OK.
 DHW PROGRAM
Here, you can set the periods when DHW is heated with reference
to the set day temperatures. In the other phases, the set night
temperatures are followed. The times are set as for the heating
programs. You can select the set values for day and night mode
as described in the DHW chapter.
Example: You want to heat up DHW daily at two different times,
i.e. from 22:00h until 05:00h the following day, and then again
from 08:00h until 11:00h. Since the day begins at 00:00h, begin
programming at 00:00h. The first pair of switching times runs
from 00:00h until 05:00h. The second pair of switching times
starts at 08:00h and ends at 11:00h. The third switching time
pair runs from 22:00h until 24:00h.
The pairs of switching times should be selected so that the DHW
cylinder can be completely heated up between the start and stop
times (at least 3 hours).
 FAN PROGRAM
The setting is made as for the central heating and DHW programs.
 HOLIDAY PROGRAM
During the holidays, if nobody is in the house, central heating,
DHW and ventilation are not required in their full scope. All set
temperatures are set to match the set values of the standby func-
tion. Define the first and last days of the holiday. The setting is
made as described under “Time / date”. At the end of the holiday,
the appliance runs according to the set programs again.
