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 (
not displayed), by pressing the pr
INFORMATION
■
Only use the pr button to enable or disable the
schedule timer. The schedule timer overrules the
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
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
■
Manually adjust the clock for summertime and
wintertime. Refer to "Setting the clock" on page
■
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
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.
To set up the SCHEDULE TIMER refer to chapter

What can the schedule timer do?
The schedule timer allows the programming of:
1. Space heating (refer to "Programming space heating or
domestic water heating" on page
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 space cooling, quiet
mode, or booster heater mode" on page
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.
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.
3. Quiet mode (refer to "Programming space cooling, quiet mode,
or booster heater mode" on page
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
domestic water heating" on page
[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 or 5
Switch the mode on or off at a scheduled time. The switch set to
on means enabeling the programmed storage and reheat
operation.
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
switched off. Note that this has no influence on
domestic water heating.
■
[4-03]=4 or 5. In 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
domestic hot water reheat" on page
