Operation example : Schedule timer based on ON/OFF instruction.
When setback function (refer to "[2] Automatic setback function" on
page 19 ) is enabled, the setback operation will have priority over the
scheduled action in the schedule timer if ON instruction is active. If

Method 2 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 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 the operation manual.
The controller will be switched off (operation LED will
stop working).
However the schedule timer icon will stay displayed.
When pushing
the button
The schedule timer for space heating will be stopped and
will not start again.
The schedule timer icon will not be displayed anymore.
