Domestic water heating
Refer to
"Programming domestic water heating" on page 15
Domestic water heating can be done through several standard
operation modes:
■
Automatic storage: by field setting, once during night and/or
once during the afternoon the water is heated till storage set
point.
■
Manual storage: if due to special circumstances, production of
hot water (till storage set point) is needed immediately (1 time),
this function can be used.
■
Reheat: the reheat function can be activated next to or separate
from the automatic storage operation if the user wants to keep
the domestic hot water tank at the minimum reheat temperature.
Next to the standard domestic water heating operation modes, it is
also possible to freely program the domestic water heating operation
through the schedule timer (refer to
). Then the mode is switched on or off at a
scheduled time. 4 actions can be programmed per mode. These
actions are repeated daily (additional schedule of storage on top of
the automatic day and night storage functionality).
Quiet mode
Refer to
"Programming quiet mode" on page 16
Switch the mode on or off at a scheduled time. 4 actions can be
programmed per mode. These actions are repeated daily.

Programming and consulting the schedule timer
Programming the schedule timer is flexible (you can add, remove or
alter programmed actions whenever required) and straightforward
(programming steps are limited to a minimum). However, before
programming the schedule timer, remind:
■
Familiarize yourself with the icons and the buttons. You will need
them when programming. Refer to
.
■
Fill out the form at the very end of this manual. This form can
help you define the required actions for each day.
■
Take your time to enter all data accurately.
■
Try to program the actions in a chronological way: start with
action 1 for the first action and end with the highest number for
the last action. This is not a requirement but will simplify the
interpretation of the program later.
■
If 2 or more actions are programmed for the same day and at the
same time, only the action with the highest action number will be
executed.
Example:
■
You can always alter, add or remove the programmed actions
later.
INFORMATION
■
Remark that only the time when domestic water
heating must start and stop can be programmed in the
schedule timer. When domestic water heating is
enabled, the water will be heated till storage set point.
The storage set point is set through field setting.
■
For energy-saving reasons, keep hours with low
electricity cost tariffs in mind when programming the
schedule timer for domestic water heating.
INFORMATION
■
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 (if time
is shorter than 2 hours). 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
"5.2. Setting the clock" on page 5
.
■
When the schedule timer is not enabled ( icon not
displayed), schedule timer actions will not be
executed!
■
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.
