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
). 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
consulting the schedule timer" on page 7
What can the schedule timer do?
The schedule timer allows the programming of:
1
Space heating and space cooling (refer to
cooling or space heating" on page 8
Switch on the desired mode at a scheduled time, in combination
with a set point (weather dependent or manually set). Five
actions per weekday can be programmed, totalling 35 actions.
2
Quiet mode (refer to
"Programming quiet mode, booster heating or
)
Switch the mode on or off at a scheduled time. Five actions can
be programmed per mode. These actions are repeated daily.
3
Booster heating (refer to
"Programming quiet mode, booster heating
or sanitary heating" on page 9
)
Allow or disallow booster heating at a scheduled time. Five
actions can be programmed per mode. These actions are
repeated daily.
4
Sanitary heating (refer to
"Programming quiet mode, booster heating
or sanitary heating" on page 9
)
Switch the mode on or off at a scheduled time. Five actions can
be programmed per mode. These actions are repeated daily.
NOTE
■
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
■
Manually adjust the clock for summertime and
wintertime. Refer to
■
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
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.
NOTE
When the unit is connected to an external room
thermostat, the schedule timer for space cooling and
space heating is overruled by the external room
thermostat.
■
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
sanitary water heating.
