4.5.7.7 - Description of the Holidays sub-menus

This function is used to define 16 public holiday periods. Each period is defined with the aid of three parameters: the month, starting day and duration of the public holiday period. During these public holidays the controller will be in occupied or unoccupied mode, depending on the programmed periods validated for public holidays (see section 4.5.7.8).

Each of these public holiday periods can be displayed and changed with the aid of a sub-menu.

ATTENTION: The broadcast function must be activated to utilise the holiday schedule, even if the unit is running in stand-alone mode (not connected to CCN). See section 4.5.7.6.

NOTE: Typical programming for public holidays:

-A public holiday period lasting 1 day on 20th May, for instance, is configured as follows: start month = 5, start day = 20, duration = 1

-A public holiday period lasting 2 day on 25th May, for instance, is configured as follows: start month = 5, start day = 25, duration = 2

4.5.7.8 - Description of the Broadcast sub-menu

The controller provides a broadcast configuration menu which you can use to configure the unit to be the CCN’s broadcaster, responsible for transmitting the time, outdoor temperature, and holiday flags to all system elements.

This menu also authorises setting the date to begin and end daylight saving time. There should be only one broadcaster in a CCN, so this table should not be configured if any other system element is acting as broadcaster.

ATTENTION: If the unit operates in standalone mode (not CCN connected) this menu must be used if the holiday function is used, or to correct for daylight saving time.
