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 5). 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 (
not displayed), by pressing the

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.

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 4.
Manually adjust the clock for summertime and
wintertime. Refer to "Setting the clock" on page 4.
A power failure exceeding 1 hour 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 4 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.
To set up the SCHEDULE TIMER refer to chapter "Programming and
consulting the schedule timer" on page 7.
