[0-03]=0 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 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.
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.
Operation example: Schedule timer based on ON/OFF instruction.
When setback function is enabled, the setback operation will have
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.

[1] Automatic storage timing for domestic water heating
In this mode, the indoor unit will deliver hot water to the domestic hot
water tank based on the daily fixed pattern. This mode will continue
until storage temperature is reached.
Automatic storage is the advised domestic hot water mode. In this
mode water heats up during the night (when space heating
requirements are lower) until the storage set point. The heated water
is stored in the domestic hot water tank at a higher temperature so it
can fulfil the domestic hot water requirements throughout the day.
The storage temperature set point and timing are field settings.
■
[1-00] Status: defines whether the domestic water heating
(storage mode) during night is enabled (1) or not (0).
■
[1-01] Start time: time of the night at which the domestic water
should be heated.
■
[1-02] Status: defines whether the domestic water heating
(storage mode) during daytime is enabled (1) or not (0).
■
[1-03] Start time: time of the day at which the domestic water
should be heated.
■
NOTE Make sure the domestic hot water is only heated up
to the domestic hot water temperature you require.
Start with a low domestic hot water storage
temperature set point, and only increase if you
feel that the
temperature is not sufficient for your needs (this
depends on your water using pattern).
■
Make sure the domestic hot water is not heated
unnecessary. Start with activating automatic
storage during night (default setting). If it seems
that the domestic hot water night storage
operation is not sufficient for your needs, an
additional storage during daytime can be set.
■
For energy-saving purposes, it is advised to
enable the weather dependent domestic water
heating. Refer to setting "[b-02]" on page 24.
■
To activate the domestic hot water mode press
the pr button, the p icon should be displayed.
Refer to "[b] Domestic hot water set points" on page 24 for
temperature set points.
[2] Automatic setback function
Setback function provides the possibility to lower the room
temperature. The setback function can for instance be activated
during the night because the temperature demands during night and
day are not the same.
■
NOTE By default the setback function is enabled.
■
The setback function can be combined with the
automatic weather dependent set point operation.
■
Setback function is an automatic daily scheduled
function.
■
[2-00] Status: defines whether the setback function is turned ON
(1) or OFF (0)
■
[2-01] Start time: time at which setback is started
■
[2-02] Stop time: time at which setback is stopped
