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). Note that this has no influence on the domestic
water heating.
When pushing
The schedule timer for space heating will stop (when
the y button
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
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.
When pushing
The schedule timer for space heating and domestic
the r/p button
water heating along with the quiet mode will be stopped
and will not start again.
The schedule timer icon will not be displayed anymore.
