5.2.4 Calendar entry
A maximum of 16 entries can be made. The entries are sorted in chronological order.
Every entry must include:
• Date, year and starting time
• Date and end time
• Reason for entry (holidays or special days)
Main menu > Heating circuit > Holidays/special days > Calendar
Operating line Range Factory setting
Entry 1… entry 16
Start / End / Reason
--- / --- / Holidays
Annually recurring holidays or special days can be entered by setting an asterisk (*) for
the annual setting.
If 2 entries overlap, following applies: Special days have priority over holidays. Hence, it
is also possible to have a special day during a holiday period.
An example of a special day during the holiday period would be a theatre performance
in a school building.
At the end of the holiday period or special day, operation according to the normal 7-day
program is resumed. During this transition period, it can occur that optimum start
control (e.g. boost heating) cannot be started in due time. It is therefore recommended
to bring the end of the holiday period somewhat forward, thereby giving the plant
sufficient time to adapt to the respective setpoints.
5.2.5 Control inputs for holidays and special days
Holidays and special days can also be activated via digital inputs. For that purpose,
digital inputs must be assigned.
Main menu > Commissioning > Extra configuration > Heating circuits > Inputs
Operating line Range Factory setting
Holiday input RMK770…, RMZ7…* ---
Special day input RMK770…, RMZ7…* ---
* Here, the free inputs are available for selection
These inputs are active only if holidays / special day operation is set to “Autonomous“
or “Master”.
The digital input enables the plant to constantly use the special day program set in the
7-day program without necessitating interventions on the controller.
When the configured input is activated, the special day program becomes active. This
program is maintained until the input becomes inactive. Then, the normal 7-day pro-
gram is resumed.
The digital input enables the plant to be constantly switched to ”Holidays” mode without
necessitating interventions on the controller.
When the configured input is activated, the plant switches to the “Holidays” mode. This
program is maintained until the input becomes inactive. Then, the normal 7-day pro-
gram is resumed.
If, at the same time, a special day or a holiday period is activated via the control
switches and an entry in the calendar, the following priorities apply:
1. Control switch “Special day”
2. Control switch “Holidays”
3. “Special day” entry in the calendar
4. “Holidays” entry in the calendar
