In heating mode ( h ), the water temperature set point can
also be weather dependent (icon
This means that the controller calculates the water
temperature set point based on the outdoor temperature.
In this case, instead of showing the water temperature set
point, the controller shows the "shift value" which can be
set by the user. This shift value is the temperature
difference between the temperature set point calculated by
the controller and the real set point. E.g. a positive shift
value means that the real temperature set point will be
higher than the calculated set point.

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.
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.
To set up the SCHEDULE TIMER refer to chapter "Programming and
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 "Programming space
heating or space cooling" 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.
NOTE 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.
