11.3.8. 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 (
p
icon displayed) or disabled (
p
icon
not displayed) by pressing the
pr
button.
Space cooling
Refer to "Programming space cooling" on page 34 .
4 actions can be programmed, these actions are repeated daily.
The space cooling schedule timer can be programmed in 2 different
ways:

Based on the temperature set point (leaving water temperature
and room temperature).
 Based on the ON/OFF instruction.
The desired method is set through field setting. Refer to "8.3. Field
settings" on page 17 for a detailed description how to set one or more
field settings.

[0-04] Status: defines whether ON/OFF instruction can be used
in the schedule timer for space cooling.
The implementation and meaning of setting [0-04] and schedule
settings are the same as for heating operation. See
"Operation
example: Schedule timer based on temperature set points" on
page 32
and "Operation example: Schedule timer based on ON/OFF
instruction" on page 33 .
For cooling, no setback function is available.
11.3.9. Space heating
Refer to "Programming space heating" on page 35 .
Four 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 the chapter
"8.3. Field settings" on page 17 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.

INFORMATION
By default space cooling based on temperature set point
(method 1) is enabled, so only temperature shifts are
possible (no ON/OFF instruction).

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
y
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).
When pushing
the
pr
button
The schedule timer for space heating 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).
When pushing
the
y
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 36
.
The controller will be switched off (operation LED will
stop working).
However the schedule timer icon will stay displayed.
When pushing
the
pr
button
The schedule timer for space heating will be stopped and
will not start again.
The schedule timer icon will not be displayed anymore.
