Operation example
: Schedule timer based on ON/OFF instruction

priority over the scheduled action in the schedule timer if ON
instruction is active. If OFF instruction is active this will have priority
over the setback function. At any time the OFF instruction will have
the highest priority.

Space heating based on ON/OFF instruction
During operation
When the schedule timer switches space heating OFF,
the controller will be switched off (operation LED will stop
working).
When pushing
the
y
button
The schedule timer for space heating will stop (when
active at that moment) and will start again at the next
scheduled ON function.
The "last" programmed command overrules 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 35.
The controller will be switched off (operation LED will
stop working).
However the schedule timer icon will stay displayed.
When pushing
the
pr
button
The schedule timer for space heating will be stopped and
will not start again.
The schedule timer icon will not be displayed anymore.

INFORMATION
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 (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 "10.3.3. Setting up the controller" on
page 28.
When the schedule timer is not enabled (
p
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.
