What can the schedule timer NOT do?

The schedule timer can not change the operation mode from space
heating to space cooling or vice versa.

How to interpret the programmed actions

To be able to understand the behaviour of your installation when the
schedule timer is enabled, it is important to keep in mind that the
"last" programmed command overruled the "preceding" programmed
command and will remain active until the "next" programmed
command occurs.

Example: imagine the actual time is 17:30 and actions are
programmed at 13:00, 16:00 and 19:00. The "last" programmed
command (16:00) overruled the "previous" programmed command
(13:00) and will remain active until the "next" programmed command
(19:00) occurs.

So in order to know the actual setting, one should consult the last
programmed command. It is clear that the "last" programmed
command may date from the day before. Refer to 

"Consulting

programmed actions" on page 12

.

4.7.

Programming and consulting the schedule timer

Getting started

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:

■

Familiarise yourself with the icons and the buttons. You will need
them when programming. Refer to 

"4.3. Name and function of

buttons and icons" on page 4

.

■

Fill out the form at the very end of this manual. This form can
help you define the required actions for each day. Keep in mind
that:
-

In the space heating and domestic water heating program, 4 
actions can be programmed per weekday. The same actions 
are repeated on a weekly basis.

-

In the space cooling, quiet mode, and booster heater mode

(1)

program, 4 actions can be programmed per mode. The same 
actions are repeated on a daily basis.

■

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.

■

You can always alter, add or remove the programmed actions
later.

INFORMATION

■

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
domestic water heating.

■

[4-03]=4 or 5. In case no domestic water heating
actions are programmed, enabling or disabling the
schedule timer will only have influence on the space
heating, cooling and quite mode. In this way it is
possible to separate on one hand the space heating,
cooling and quite mode scheduled action as part of
the schedule timer and on the other hand the storage
and reheat operation of the domestic water heating.
In this way, it is easy to disable the space heating and
cooling by disabling the schedule timer with keeping
the storage and reheat domestic water heating
enabled (refer to 

"Scheduled domestic hot water

storage" on page 

15

 and 

"Scheduled/continuous

domestic hot water reheat" on page 15

).

NOTICE

The setting [4-03] shall not be modified. The installer
selected the proper setting for your application.

INFORMATION

The status of this setting is only mentioned to indicate
which settings and functions are applicable for your
application.

[4-03]=0, 1, 2, 3, or 4 is only for domestic hot water tank
with built-in electrical booster heater (EKHW*).

[4-03]=5 is only for domestic hot water tank without
electrical booster heater (EKHTS).

INFORMATION

During schedule timer operation, someone may have
altered the actual settings manually (in other words, the
"last" command was overruled manually). The icon 

p

,

indicating the schedule timer operation, may still be
displayed, giving the impression that the "last" command
settings are still active. The "next" programmed command
will overrule the altered settings and return to the original
program.

(1) Only applicable for tank with built-in electrical booster heater (EKHW*).
