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.
NOTE During schedule timer operation, someone may have altered the actual settings manually (in
other words, the “last” command was overruled manually). The icon , indicating the
schedule timer operation, may still be displayed, giving the impression that the “last”
command settings are still active. The “next” programmed command will overrule the
altered settings and return to the original program.
Programming and consulting the schedule timer
Getting started
Programming the schedule timer is flexible and straightforward (programming steps are limited to a
minute). However, before programming the schedule timer, remind:
Familiarize yourself with the icons and the buttons. You will need them when programming.
Fill out the form at the very end of this manual. This form can help you define the required
actions each day. Keep in mind that:
- In the space cooling/heating program, 3 actions can be programmed per weekday. The same
actions are repeated on a weekly basis.
- In the domestic water heating, 3 actions can be programmed per day. The same actions are
repeated on 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 the programmed actions later.
When programming heating actions (time and set point), cooling actions are added
automatically at the same time but with the predefined default cooling set point. Conversely,
when programming cooling actions (time and set point), heating actions are added automatically
at the same time but with the default heating set point.
The set points 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 set points and vice versa.
Due to fact that the schedule timer cannot switch between operation modes (cooling and
heating) and the fact that each programmed action implies a cooling set point and a heating set point,
the following situations may occur:
·
When the schedule timer is active in heating mode, and the mode is changed manually to
