When the option
‘Use event colors for value’
is enabled, the three available event colors are
assigned to the available value presets in a round robin fashion. The first value will use
event color 1, the second value will use event color 2, and the third value is drawn in event
color 3. If there are more values available, the color assignment will start at color 1 again
(value 4 uses color 1 and so on). This mode is especially suitable for schedules where
events do not normally overlap each other or overlapping events typically also use different
values. Also, this mode works best if the number of distinct values is small, for example
occupied/unoccupied/override or other small enumerations. It may cause confusion in
schedules where arbitrary discrete values are entered, like for example a temperature set-
point. In such a system, adding a new value which is lower than another already used value,
the color assignments will change. In this case, the option should be turned off to use the
standard color mode (see below).
When the option is not selected, the colors are used such that events of different priority use
different colors. All events are internally sorted by priority and then drawn in groups of
same priority events. For each new group, a new event color is used. If more than three
different priority levels are used on the same day, the event colors will be re-used in a
round robin fashion. This mode is especially suitable in situations where a large number of
different values are used and frequently changed, for example when a temperature set-point
or other discrete value is scheduled. The color selection in this mode will cause all values
scheduled at standard priority to be drawn in event color 1, with colors 2 and 3 only used
for values scheduled at the same day at higher priorities. In case these events overlap the
lower priority events, the overlapping will be clearly visible because the color of the higher
priority event is different. For schedules which use a small number of fixed output values,
for example occupied/unoccupied/override, this mode may cause confusion because
‘unoccupied’ may be drawn in different colors on different days, depending on the priority,
when the user would expect the same color to be used consistently for the individual
enumerations.
9.5.9.6 Access Levels
The
Access Control
property page is used to define access levels for various operations
which may need to be restricted because they modify schedule configuration data. These
restrictions apply in addition to the general required access level for the control, as set on
the
Common
property page. The following operations can be protected individually:
Change time of existing events:
This operation allows the user to change the time
(hour and minute) at which a value presets is scheduled. The entry in the time
table must already be there, since this operation only allows modifying the time
for existing entries.
Change preset selection:
This operation allows the user to change the value
preset which is scheduled at a certain time. The entry in the time table must
already exist, the user may select a different preset from the list of available
presets, for example change the air condition from economy to comfort.
Edit values of existing presets:
This operation allows changing the physical
values which are assigned to existing value presets. The user may for example
change the light level assigned to the bright setting from 80 to 100 percent.
Define new presets:
This operation allows the user to define new value presets, if
the scheduler unit controls only one value.
Add and remove entries:
This operation allows the user to add and remove entries
in the time table. Also bound to this operation are the related operations to clear
entire days, copy them to other days, as well as enabling and disabling individual
days.
