INTRODUCTION
The push-button RTR allows you to operate numerous
sections in a building. The functions of the push-button
depend on the programming and the other EIB instal-
lation devices.
To keep operation of the device as easy as possible, the
installer can pre-set functions (basic display, required
values, timer, etc.) or activate them to suit individual
needs. The present document will offer you an intro-
duction to this device.

FUNCTIONS
1.1. Overview of functions
The push-button RTR unites the functions of a push-
button, room temperature regulator, timer and display
unit in a single device.
When activated, the function buttons can perform the
following functions:
-switching on and dimming the lights
-closing/opening blinds etc. and bringing them into position
-calling up and saving eight light scenes
-transmitting temperature and brightness values
-specifying operating modes for the room temperature
regulator
-activating/deactivating the room temperature timer
-activating/deactivating weekday timers
The display with two integrated buttons can:
-change the room temperature easily at short notice
-display the room and/or outside temperature as well
as the desired set temperature
-display the date and time
-display messages (e.g. alarm messages)
-change the desired set temperature values for the
various operating modes
-program the room temperature timer on site
-program the two week timers on site
-change the basic settings
The LEDs on the side show the status indication and the
operation indication for the function buttons. In addition, they
can be left on or off permanently.

1.2. Basic display
The display represents one of nine possible basic
displays. Three different displays are described by way
of example in the following:
NOTES
The easiest way to access the basic display: press any
function button at all. You may have to press it several
times (see ch. 1.4). You will find information on the
display lighting in Chapter 5.4.
1.3. Push-button assistance
The push-button assistance is only available for the
function buttons and allows you to briefly display the
function of a particular button.
Briefly press the button whose function you are
unsure of.
If you press the previously selected function button for
slightly longer, the programmed function is triggered.
In this example, the light scene “Watching TV” was
called up.
NOTE
The push-button assistance may be deactivated. In this
case, the basic display will remain unchanged (ch. 5.4.).
The function of the button is displayed in
the bottom line of the three-line display.

OPERATING LEVEL
2.1. Blocking menus
You can make wide-ranging changes in the saved
menus. In order to ensure easy, clear operation while
also offering a large number of functions, specific setting
options can be blocked or activated.
Your installer can specify three blocking levels:
Level I: You can adjust the desired set temperature
value using the display keys.
- Menus are not accessible!
Level II: In addition to the desired set temperature
value, you also have access to the menus.
- Switching between operating modes (see ch. 4.1.)
- Setting the »Heating temperatures«
- Setting the »Cooling temperatures«
The temperatures for »Heating« and »Cooling« are
adjusted in the same way (see ch. 4.3.).
Level III: You can access all menus as long as they
are software-based.
NOTE
The “Key symbol” in the display shows that your device
or individual functions are blocked by the software
(by means of an object) and the push-button lock is
activated via the »Settings« menu.

MENU NAVIGATION
2.2. General information about menu navigation
You mainly use the display buttons to navigate the menu.
The following options are available:
Press one single display button:
- Select or change the menu item
or
- Lower/raise the value
Press both display buttons simultaneously:
press “Enter” to confirm the value (it may have changed)
Press any function button at all:
Return to the superordinate menu without accepting
the value (= “ESC”), press the key several times to
return to the basic display.
If no push-button have been operated for more
than 20 sec.:

2.3. Menu sequence
a. Deviations in function and display
The push-button RTR is adjusted to suit your individual
needs and building functions. The programming which
the installer has performed has a decisive influence on
the menu display. Only those menu levels which you
actually require are displayed.
This makes the device clearly arranged and easier
to operate. However, specific menu items described in
this manual are not to be found in their individual menu
structure.
Some examples:
-Timers which are not required are deactivated:
e.g. »Timer 1« menu is not displayed.
-You do not own a air-condition system:
»Cooling temperatures« menu is not displayed.
b. Entering the main menus
The menus offer you numerous setting options. Proceed
as follows to enter the menus:
While in the basic display or the required value
display, press the left and right display button for at
least 3 seconds (= “ENTER”):
Programming mode is activated; the first
main menu is displayed (see ch. 4.1.).

MESSAGES
2.4. Displaying messages
The push-button RTR allows you to display messages
such as alarms in the bottom display line.

A text message has highest priority in the push-button
functions, i.e.:
-Operations on the push-button RTR are aborted
(e.g. stopping the function buttons)
-Push-button assistance displays are aborted
-Menu operations are aborted
(e.g. programming a timer)
A text message remains displayed until it is acknowledged.
New text messages overwrite the previous message.
b. Acknowledging text messages
A text message is displayed.
Press any button at all:
The basic display is re-activated.

set value (which you have just set) normally returns to its
original value.
The new set value is shown in the
display. Press and hold to change the
value in 1.0 steps.

The push-button RTR makes various operating modes
available in the following order:
“Comfort” (normal use of the house during the day)
“Standby” (leaving the company, e.g. day trip)
“Night” (limited use is made of the house)
“Frost/heat protection” (longer absence e.g.
a holiday lasting several weeks)
a. Calling up the main menu
Change the operating mode as follows:
While in the basic display or the desired set value
display, press the left and right display button for
at least 3 seconds (= “ENTER”):

lengthening. This is activated either by a “Presence but-
ton” (function button with this definition) or automatically,
e.g. by a presence detector, and displayed as follows:
Comfort lengthening “Night” (e.g. watch television
for longer or unexpected visit)
Comfort lengthening “Frost/heat protection”
(e.g. if the start of your holiday is delayed)
When the comfort lengthening is activated, the comfort
temperature is retained for a time programmed by the
installer even though the operating mode changes.

HOW IT WORKS
5.1. Using the room temperature timer
a. How the push-button RTR works
The push-button RTR compares the actual room temper-
ature with the desired set temperature and then decides
whether, and how far the heating valves must be opened
or closed. The operating mode determines the specified
temperature value.
You can use the timer to determine the time at which an
operating mode is performed. You can combine the
following categories freely for this purpose:
-Operating modes “Comfort”, “Standby”, “Night”
-Select the day of the week or a group of days such
as Mo-Fr or Sa-Su.
-Operating time between 0:00 and 11:59pm
b. Setting criteria
In practice, every heater needs a specific length of time
in order to bring a cold room to the desired temperature.
For this reason, the room temperature should only be
lowered by approx. 4 °C at night (see ch. 4.3.).
Unlike radiators, floor heaters work with a lower water
temperature but a larger storage area and therefore
reacts relatively lethargically. You should not forget to
switch over to daily mode on time each morning. On the
other hand, you can also switch over to night-time mode
very early because the floor stores the heat very well.
