Programming And Consulting The Schedule Timer - Daikin EWAQ005ADVP Operation Manual

What can the schedule timer do?
The schedule timer allows the following programming of heating or
cooling: switch on the desired mode at a scheduled time, in
combination with a set point (automatically calculated or manually
set). Five actions per weekday can be programmed, totalling 35
actions.
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.
What can the schedule timer NOT do?
The schedule timer can not change the operation mode from cooling
to heating or vice versa when the actual operation mode has been
selected manually (by using the = button).
How to interpret the programmed actions
To be able to understand the behaviour of your installation when the
schedule timer is enabled, it is important to keep in mind that the
"last" programmed command overruled the "preceding" programmed
command and will remain active until the "next" programmed
command occurs.
Example: imagine the actual time is 17:30 and actions are
programmed at 13:00, 16:00 and 19:00. The "last" programmed
command (16:00) overruled the "previous" programmed command
(13:00) and will remain active until the "next" programmed command
(19:00) occurs.
So in order to know the actual setting, one should consult the last
programmed command. It is clear that the "last" programmed
command may date from the day before. Refer to
programmed actions" on page 7
actions.
NOTE During schedule timer operation, someone may have
altered the actual settings manually (in other words,
the "last" comand was overruled manually). The icon
p, indicating the schedule timer operation, may still be
displayed, giving the impression that the "last"
command settings
programmed command will overrule the altered
settings and return to the original program.

2.6. Programming and consulting the schedule timer

2.6.1. 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
buttons and icons" on page
■
Fill out the form at the very end of this manual. This form can
help you define the required actions for each day. Keep in mind
that:
- In the cooling/heating program, 5 actions can be
programmed per day. The same actions are repeated on a
weekly basis.
- In the quiet mode program, 5 actions can be programmed.
The same actions are repeated on a daily basis.
■
Take your time to enter all data accurately.
■
Try 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.
■
You can always alter, add or remove the programmed actions
later.
■
When programming heating actions (time and setpoint), cooling
actions are added automatically at the same time but with the
predefined default cooling
programming cooling actions (time and setpoint), heating
actions are added automatically at the same time but with the
default heating setpoint.
The setpoints of these automatically added actions can be
adjusted by programming the corresponding mode. This means
that after programming heating, you should also program the
corresponding cooling setpoints and vice versa.
Due to the fact that the schedule timer cannot switch
between operation modes (cooling or heating) and the fact
that each programmed action implies a cooling setpoint
and a heating setpoint, the following situations may occur:
■
when the schedule timer is active and in heating
mode, and cooling is selected manually (by means of
the = button), the operation mode will from then on
remain cooling and program actions will follow the
corresponding cooling setpoints. Returning to heating
mode needs to be carried out manually (by means of
the = button).
■
when the schedule timer is active and in cooling
mode, and heating is selected manually (by means of
the = button), the operation mode will from then on
remain heating and program actions will follow the
corresponding heating setpoints. Returning to cooling
mode needs to be carried out manually (by means of
the = button).
The above proves the importance of programming both
cooling and heating setpoints for each action. If you do not
program these setpoints, the predefined default values will
be used.
