5.8.3. Quiet mode
Refer to "Programming quiet mode" on page 36.
Switch the mode on or off at a scheduled time. Four actions can be
programmed per mode. These actions are repeated daily.
5.9. Programming and consulting the schedule timer
5.9.1. Getting started
Programming the schedule timer is flexible (you can add, remove or
alter programmed actions whenever required) and straightforward
(programming steps are limited to a minimum). However, before
programming the schedule timer, remind:
■ Familiarise yourself with the icons and the buttons. You will need
them when programming. Refer to "5.2. Name and function of
buttons and icons" on page 27.
■ Fill out the form at the very end of this manual. This form can
help you define the required actions for each day.
■ Take your time to enter all data accurately.
■ Tr y to program the actions in a chronological way: start with
action 1 for the first action and end with the highest number for
the last action. This is not a requirement but will simplify the
interpretation of the program later.
■ If 2 or more actions are programmed for the same day and at the
same time, only the action with the highest action number will be
executed.
Example:
■ You can always alter, add or remove the programmed actions
later.
INFORMATION
■ When power returns after a power supply failure, the
auto restart function reapplies the remote controller
settings at the time of the power supply failure (if time
is shorter than 2 hours). It is therefore recommended
to leave the auto restart function enabled.
■ The programmed schedule is time driven. Therefore, it
is essential to set the clock and the day of the week
correctly.
Refer to "5.3. Setting up the controller" on page 28.
■ When the schedule timer is not enabled ( icon not
displayed), schedule timer actions will not be
executed!
■ The programmed actions are not stored according to
their timing but according to the time of programming.
This means that the action that was programmed first
gets action number 1, even though it is executed after
other programmed action numbers.
