Space heating based on ON/OFF instruction
When the schedule timer switches space heating OFF, the controller will be
switched off (operation LED will stop working). Note that this has no influence
on the domestic water heating.
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 which means that the
domestic heating stays enabled.
the quiet mode will be stopped and will not start again.
The schedule timer icon will not be displayed anymore.
