Programming And Consulting The Schedule Timer; Getting Started - Rotex RKHBH008AA Manuel D'utilisation

What can the schedule timer do?
The schedule timer allows the programming of:
1. Space heating and space cooling (refer to "Programming space
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.
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.
2. Quiet mode (refer to "Programming quiet mode, booster heating
or domestic water 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.
3. Booster heating (refer to "Programming quiet mode, booster
heating or domestic water 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. Domestic water heating (refer to "Programming quiet mode,
booster heating or domestic water 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.
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
switched off. Note that this has no influence on
domestic water heating.
What can the schedule timer NOT do?
The schedule timer can not change the operation mode from space
cooling to space heating 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 9.
NOTE 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
programmed command will overrule the altered
settings and return to the original program.

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 "Name and function of
buttons and icons" on page 3.
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 cooling/heating program, 5 actions can be
programmed per weekday. The same actions are repeated
on a weekly basis.
- In the domestic water heating, booster heater and quiet
mode program, 5 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.
When programming heating actions (time and set point), cooling
actions are added automatically at the same time but with the
predefined default cooling set point. Conversely, when
programming cooling actions (time and setpoint), heating
actions are added automatically at the same time but with the
default heating set point.
The set points of these automatically added actions can be
adjusted by programming the corresponding mode. This means
that after programming heating, you should also program the
corresponding cooling set points and vice versa.
Due to the fact that the schedule timer cannot switch
between operation modes (cooling or heating) and the fact
that each programmed action implies a cooling setpoint
and a heating setpoint, the following situations may occur:
when the schedule timer is active in heating mode,
and the mode is changed manually to cooling (by
means of the = button), the operation mode will
from then on remain cooling and program actions will
follow the corresponding cooling setpoints. Returning
to heating mode needs to be carried out manually (by
means of the = button).
when the schedule timer is active in cooling mode,
and the mode is changed manually to heating (by
means of the = button), the operation mode will
from then on remain heating and program actions will
follow the corresponding heating setpoints. Returning
to cooling mode needs to be carried out manually (by
means of the = button).
The above proves the importance of programming both
cooling and heating setpoints for each action. If you do not
program these setpoints, the predefined default values will
be used.
