The special day is a 24-hour program that can be activated either via the holidays
program or an external contact.
Activation of the special day is described in section 5.2 “Holidays / special days”.
If the controller anticipates a time switch signal via bus, but the signal is not sent, the
controller operates in ”Comfort“ mode and fault status message System time switch failure
1 is delivered.
For each day, a maximum of 6 entries can be made in the 24-hour program.
For an entry, following must be entered:
• Time of day from where the desired operating mode shall apply
• The required operating mode
The next day always adopts the operating mode of the previous day until a specific
entry is made.

for the whole day and shown as a broken line.
The special day starts and ends with the same operating mode.

hour program that would have been valid without the special day.
