6.10.5 Control input "Holidays / special days"
The holidays and special days can also be activated via digital inputs. To do this,
digital inputs must be assigned.
Main menu > Commissioning > Extra configuration > Operating mode > (A, U)
Main menu > Commissioning > Extra configuration > Time switch 1 > (P and C)
Operating line Adjustable values / remarks
Holiday input ---, N.X1, N.X2, ... (digital inputs only)
Special day input ---, N.X1, N.X2, ... (digital inputs only)
These inputs have an effect only if holidays / special day is set to "Autonomous" or
"Master".
Activation of special day or holidays via digital inputs is not entered in the holidays /
special day program, eliminating recurrence.
The digital input enables the plant to be constantly switched to the special day
program in the 7-day program without requiring interventions on the controller.
If a permanent signal is applied to the configured input, the special day program
becomes active. This program is maintained until there is no more signal. Only
then does the normal 7-day program resume operation.
The digital input enables the plant to be constantly switched to "Holidays" without
requiring intervention on the controller.
If a permanent signal is applied to the configured input, the plant changes to
"Holidays". This operating mode is maintained until there is no more signal. Only
then does the normal 7-day program resume operation.
If a special day or holidays are activated simultaneously via control switches and
entry in the calendar, the following priority list applies:
 Control switch "Special day"
 Control switch "Holidays"
 "Special day" entry in the calendar
 "Holidays" entry in the calendar
If other controllers are configured as slaves in the same holidays / special day
zone, the digital inputs also act on these controllers.
6.10.6 Troubleshooting
Only one master may be set per holidays / special day zone. If several controllers
are set as master, a fault status message appears. The fault status signal is sent
by the controller receiving two holidays / special day signals.
If the controller expects a holidays / special day signal from the bus and the signal
is not sent, a fault status message "Holidays / special day program failure"
appears. The operating modes of the 7-day program are used without considering
the holidays / special day entries.

When evaluating the priority in the holidays / special day program, only the first two
entries are considered. If more than two overlapping entries are made, the special
day may no longer have priority over the holidays.
