Schedule timer operation
In schedule timer operation, the installation is controlled by the
schedule timer. The actions programmed in the schedule timer will be
executed automatically.
INFORMATION
Default: the schedule timer is set as follows.
Sunday until thursday
Friday and saturday
If this does not fullfill the customers demands, it has to be
set as explained in "Programming and consulting the
schedule timer" on page 9.
The schedule timer always follows the last command until a new
command is given. This means that the user can temporarily overrule
the last programmed set point by manual operation (by pressing the
wi and wj buttons). Only during the period when the
schedule timer is active, this overruling action is possible. If schedule
timer heating is not active, it will only be possible to observe and not
to adjust the scheduled set point.
The schedule timer is enabled (
not displayed), by pressing the
unit will work in continuous operation.
INFORMATION
■
Only use the pr button to enable or disable the
schedule timer.
■
If the auto restart function is disabled, the schedule
timer will not be activated when power returns to the
unit after a power supply failure. Press the pr button
to enable the schedule timer again.
■
When power returns after a power supply failure, the
auto restart function reapplies the user interface
settings at the time of the power supply failure.
It is therefore recommended to leave the auto restart
function enabled.
INFORMATION
■
The programmed schedule is time driven. Therefore, it
is essential to set the clock and the day of the week
correctly. Refer to "Setting the clock" on page 6.
■
Manually adjust the clock for summertime and
wintertime. Refer to "Setting the clock" on page 6.
■
A power failure exceeding 2 hours will reset the clock
and the day of the week. The schedule timer will
continue operation, but with a disordered clock. Refer
to "Setting the clock" on page 6 to adjust the clock and
the day of the week.
■
The actions programmed in the schedule timer will not
be lost after a power failure so that reprogramming the
schedule timer is not required.
INFORMATION
■
When changing from continuous operation mode to
schedule timer operation mode, the unit applies the
scheduled set point.
■
When changing from schedule timer operation mode
to continuous operation mode, the unit will keep the
latest set point of the schedule timer operation mode.
Beware to manually adjust the set point if required.
To set up the SCHEDULE TIMER refer to chapter "Programming and
consulting the schedule timer" on page 9.

What can the schedule timer do?
The schedule timer allows the programming of:
1.
Domestic water heating (refer to "Programming domestic water
heating" on page 10)
Switch on the domestic water heating mode at a scheduled time
on or off in combination with a set point (auto adaptive or
manually set). Five actions per weekday can be programmed,
totalling 35 actions. When manual set point operation is required
for each action, a set point can be chosen. If the auto adaptive
button (ba) is pressed, all set points of the programmed
schedule timer will be auto adapted.
2.
Quiet mode (refer to "Programming quiet mode" on page 11)
Switch the mode on or off at a scheduled time. Five actions can
be programmed for this mode. These actions are repeated daily.
INFORMATION
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.
How to interpret the programmed actions
p
icon
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 "Consulting
programmed actions" on page 12.
INFORMATION
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.
