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 ( icon displayed) or disabled ( icon
not displayed), by pressing the
button.
To set up the SCHEDULE TIMER refer to chapter
"4.7. Programming
and consulting the schedule timer" on page 9
.
INFORMATION
When the unit is connected to an external room
thermostat, buttons
and
are not operable and the
icon
is shown. In this case, the external room
thermostat switches the unit on or off and determines the
operation mode (space heating or space cooling).

INFORMATION
■
Only use the
button to enable or disable the
schedule timer. The schedule timer overrules the
button. The
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
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 6
.
■
Manually adjust the clock for summertime and
wintertime. Refer to
"Setting the clock" on page 6
.
■
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 6
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.
