4.11. Schedule timer operation
In schedule timer operation, the installation is controlled by the
schedule timer. The actions programmed in the schedule timer will be
executed automatically.
The schedule timer is enabled ( icon displayed) or disabled ( icon
not displayed) by pressing the
button.
Space heating
Refer to
"Programming space heating" on page 14
4 actions per day of the week can be programmed, totalling 28
actions.
The space heating schedule timer can be programmed in 2 different
ways: based on the temperature set point (both leaving water
temperature and room temperature) and based on the ON/OFF
instruction.
The desired method is set through field setting. Refer to
for a detailed description how to set one or more
field settings.
■
[0-03] Status: defines whether ON/OFF instruction can be used
in the schedule timer for space heating.
In the following tables both methods on how to interpret the schedule
timer are shown.
Operation example: Schedule timer based on temperature set
points
When setback function is enabled, the setback operation will have
priority over the scheduled action in the schedule timer.
NOTE
By default space heating based on temperature set
point (method 1) is enabled, so only temperature shifts
are possible (no ON/OFF instruction).
Advantage of this method is that you can simply switch
off the space heating operation by pushing the
button without disabling the automatic domestic hot
water storage operation (e.g. during summertime when
no space heating is required).
Method 1
[0-03]=1 (default)
Space heating based on temperature set point
(a)
(a) For leaving water temperature and/or room temperature
During operation
During schedule timer operation the operation LED is lit
continuously.
When pushing
the
button
The schedule timer for space heating will stop and will
not start again.
The controller will be switched off (operation LED will
stop working).
However, the schedule timer icon will stay displayed
which means that the domestic water heating stays
enabled.
When pushing
the / button
The schedule timer for space heating and domestic
water heating along with the quiet mode will be stopped
and will not start again.
The schedule timer icon will not be displayed anymore.

Method 2
[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
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 18
.
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 / button
The schedule timer for space heating and domestic
water heating along with the quiet mode will be stopped
and will not start again.
The schedule timer icon will not be displayed anymore.
