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 always follows the last command until a new
command is given. This means that the user can temporarily overrule
the last executed programmed command by manual operation (Refer
to
"Manual operation" on page 7 ). The schedule timer will regain
control over the installation as soon as the next programmed
command of the schedule timer occurs.
The schedule timer is enabled ( p icon displayed) or disabled ( p icon
not displayed), by pressing the pr button.
To set up the SCHEDULE TIMER refer to chapter "Programming and
consulting the schedule timer" on page 9 .
What can the schedule timer do?
The schedule timer allows the programming of:
1. Space heating (refer to "Programming space heating or space
cooling" on page 10 )
Switch on the desired mode at a scheduled time, in combination
with a set point (weather dependent or manually set).
Four actions per weekday can be programmed, totalling
28 actions.
2. Space cooling (refer to "Programming quiet mode, booster
heating or domestic water heating" on page 11 ).
Switch on the desired mode at a scheduled time, in combination
with a set point (weather dependent or manually set). Four
actions can be programmed. These actions are repeated daily.
3. Quiet mode (refer to "Programming quiet mode, booster heating
or domestic water heating" on page 11 )
Switch the mode on or off at a scheduled time. Four actions can
be programmed per mode. These actions are repeated daily.
4. Domestic water heating (refer to "Programming space heating or
space cooling" on page 10 )
[4-03]=0, 1, 2, or 3
Switch the mode on or off at a scheduled time. Four actions per
weekday can be programmed, totalling 28 actions.
[4-03]=4

on means enabeling the programmed storage and reheat
operation.

INFORMATION
■
Only use the pr button to enable or disable the
schedule timer. The schedule timer overrules the y
button. The y button only overrules the schedule
timer until the next programmed action.
■
If the auto restart function is disabled, the schedule
timer will not be activated when power returns to the
unit after a power supply failure. Press the
pr button
to enable the schedule timer again.
■
When power returns after a power supply failure, the
auto restart function reapplies the user interface
settings at the time of the power supply failure.
It is therefore recommended to leave the auto restart
function enabled.
■
The programmed schedule is time driven. Therefore, it
is essential to set the clock and the day of the week
correctly. Refer to
"Setting the clock" on page 5 .
■
Manually adjust the clock for summertime and
wintertime. Refer to
"Setting the clock" on page 5 .
■
A power failure exceeding 2 hours will reset the clock
and the day of the week. The schedule timer will
continue operation, but with a disordered clock. Refer
to
"Setting the clock" on page 5 to adjust the clock and
the day of the week.
■
The actions programmed in the schedule timer will not
be lost after a power failure so that reprogramming the
schedule timer is not required.
INFORMATION
When the unit is connected to an external room thermostat,
the schedule timer for space heating and space cooling is
overruled by the external room thermostat.
INFORMATION
■
The programmed actions are not stored according to
their timing but according to the time of programming.
This means that the action that was programmed first
gets action number 1, even though it is executed after
other programmed action numbers.
■
When the schedule timer switches space heating or
space cooling
x , the controller will also be
switched off. Note that this has no influence on
domestic water heating.
■
[4-03]=4In case no domestic water heating actions
are programmed, enabling or disabling the schedule
timer will only have influence on the space heating,
cooling and quite mode. In this way it is possible to
separate on one hand the space heating, cooling and
quite mode scheduled action as part of the schedule
timer and on the other hand the storage and reheat
operation of the domestic water heating.
In this way, it is easy to disable the space heating and
cooling by disabling the schedule timer with keeping
the storage and reheat domestic water heating
enabled (refer to
"Scheduled domestic hot water
storage" on page 15 and "Scheduled/continuous
domestic hot water reheat" on page 16 ).
NOTICE
The setting [4-03] shall not be modified. The installer
selected the proper setting for your application.
