The special event calendar
A
monthly calendar
is displayed with the current day highlighted when entering the special event calendar.
Double click
on a day in the calendar to activate a dialog box to set an event for that day.
There is a choice to
not
start the oven on the selected day or to use the oven on the selected day. Selecting to
use the oven permits times to be entered for the oven to start and stop on the selected day along with a
product/recipe combination to use when starting the oven. All settings are stored in the Windows registry.
A green LED appears on the monthly calendar for the selected day if an event has been programmed.
How does the timer work?
The timer function emulates a programmable seven day home appliance timer with an active and a standby mode.
Active mode is after the timer has started the oven by closing its contact. The timer function icon button is
displayed in green with its contact closed while the timer is in active mode. Standby mode is after the timer has
stopped or shutdown the oven by opening its contact. The timer function icon button is displayed in grey with its
contact open while the timer is in standby mode. The timer shuts down the oven and changes to standby mode
when the current time is equal to the stop time setting for the current day. When the timer is in standby mode the
oven can only restarted by clicking on the timer Icon, changing the timers mode from standby to active, which
changes its contact from an open to a closed state. The timer starts the oven and changes to active mode when
the current time is equal to the start time for the current day. When the timer is in active mode the oven can be
shutdown and restarted at any time. A time setting of 00:00 for a stop or start event is disregarded and indicates
that no event has been set. This allows the timer to maintain the last state of contact over several days if required.
For example an oven can be started at the beginning of the work week with a start event setting and stopped or
shutdown at the end of the work week with a stop event setting.
IMPORTANT
Events are not permitted to be set for the current day or earlier. A message dialog is displayed
with an attem
p
t to set an invalid event.
