The control unit can be used for heating and cooling with
infinitely variable KNX positioning drives, or to control
switching actuators. It is equipped with a display, the cover of which is a rocker key. You can make the most important settings with this.You can individually identify the
keys with the labelling field in the middle. Each key has
its own status LED.The devices can signal danger and
alarm situations with a bell symbol; the 4-fold push-button even has an integrated buzzer. In addition, the 4gang push-button has an integrated IR receiver so that
the key functions can also be triggered using Merten IR
remote controls.
The push-button is connected to the KNX by attaching it
onto the flush-mounted module for the multi-function
push-button with room temperature control unit (art. no.
MTN623299, called "flush-mounted module" in the following). Parameterisation is done by the electrical installer using the KNX tool software (ETS). The stored key
functions, the behaviour of the status LEDs and the buzzer, for example, are configured in this way.

push-button. Lay the labelled transparent foil strip
on top of it.
What you need to know about the room
temperature control unit/display
With the integrated room temperature control unit, you
can control temperature in various different ways.
You can read and set important information on the
display:
• Setpoint temperature
• Operating mode (comfort, standby, night, comfort
extension)
• Workday/day off
• Display mode (setpoint temperature, actual
temperature, date etc.)
• Background lighting
• Setting time/switching time
Getting to know the display
How to operate the push-button
1 Press the programming button on the flush-mounted module.
You will see the following symbols on the display:
Comfort operation or workday. The heating is
adjusted to the set comfort setpoint temperature .
The flashing symbol means that the comfort
extension is active.
Standby operation or day off The heating is
adjusted to the set standby setpoint temperature .
Night operation. The heating is adjusted to
the set night setpoint temperature .
What you need to know about
presettings
Time control is active.
Constant display: Time synchronisation has
taken place.
When mounting the push-button, the electrical installer
performs various settings that are necessary so you can
use the push-button correctly. Most of the explanations
provided on the following pages depend on these settings. The electrical installer records the settings in question in a table for you (see „Presettings table").
Use transparent foil strips with a maximum thickness of
0.15 mm. Consult the user guide of your printer to find
out which type of foil strips you can print.
Only use the coloured foil strips as the underlay. This
ensures that the key LEDs located underneath the labelling field can shine through.

The angle of reception of the IR receiver in the push-button is about 60°. The reception range depends on the
transmission capacity of the IR remote control used. Information on this can be found in the technical data for
the IR remote control.
When operating the push-button using an IR remote
control key, the IR LED in the push-button lights up briefly.

Your electrical installer has defined six setpoint temperatures
:
• One comfort setpoint temperature (for comfort operation) each for heating and cooling
• One standby setpoint temperature (for standby operation) each for heating and cooling
• Night setpoint temperature (for night operation) for
both heating and cooling
You see the setpoint temperature of the current operation
mode. You can only change this setpoint temperature. In
order to change the setpoint temperature of another operating mode, you have to switch operating mode first
(see „Setting the operation mode“).
This new setpoint temperature is valid either until the
next time the operating mode is switched or permanently, depending on preconfiguration .
Your electrical installer has specified
within which limits this value can be changed, for example, within a minimum of 16°C to a maximum of 26°C. You cannot set a
value below or under these limit values.
If the electrical installer has made the appropriate setting
, the 4-gang push-button will give a warning sound as

Your electrical installer has defined six setpoint temperatures
:
• One comfort setpoint temperature (for comfort operation) each for heating and cooling
• One standby setpoint temperature (for standby operation) each for heating and cooling
• Night setpoint temperature (for night operation) for
both heating and cooling
You see the setpoint temperature of the current operation
mode. You can only change this setpoint temperature. In
order to change the setpoint temperature of another operating mode, you have to switch operating mode first
(see „Setting the operation mode“).
This new setpoint temperature is valid either until the
next time the operating mode is switched or permanently, depending on preconfiguration .
Your electrical installer has specified
within which limits this value can be changed, for example, within a minimum of 16°C to a maximum of 26°C. You cannot set a
value below or under these limit values.
If the electrical installer has made the appropriate setting
, the 4-gang push-button will give a warning sound as
soon as you try to exceed these limit values.
2 ou can change the value in 0.5 degree increments
by pressing the left or right key on the display.

● Setting the display
Multi-function with 1814/3.1
Here you can make all the settings required for the
multi-function push-button display. You can disable the
control menu so that the display push-buttons cannot
be used to make further changes to the settings.
You can specify the content of the display (actual
value, setpoint, time, date, external temperature, and
fan speed). You can display these values either
individually or in alternation. You can also set the
display rhythm for alternating displays. The display
mode can also be set using the control menu on the
push-button.
General
Application 1814/3.1 has been developed for the multifunction push-button with RTCU. The multi-function
push-button with RTCU is a convenient push-button
with: time control, scene functions, temperature
control, disable functions, and various display
functions.
With this application, two objects are available per
push-button.
The "push-button pair" concept is not applied here - in
other words, you can parameterise the push-buttons
independently of each other. Previously, for example,
one switch object would appear in the ETS for one
switching function per "push-button pair". In order to
realise the same function with this software, you must
connect two switch objects belonging to the two
push-buttons in question in the ETS.
Group addresses are managed dynamically. Maximum
no. of group addresses and associations: 150.
For the weekday display, you can set day "1". This
means that the first weekday can be defined as: Friday,
Saturday, Sunday or Monday. Each weekday is then
shown in the display with a different number
accordingly. You can also set the time format.
You can set the unit of temperature display (degrees/
Fahrenheit).
The first operating level is shown when the controller
is switched on ("General controller" tab - "Controller").
Here, you can set the setpoint adjustment, operation
mode adjustment or no adjustment by brief pushbutton action on the display push-button.
The background lighting on the display can either be
switched off or on at all times, or can be switched on
during operation. You can also set the persistence
period and the brightness of the background lighting.

Multi-function with 1814/3.1
● Transmit 1/8 bit toggle commands
Display
Parameter
Setting
You can simultaneously address two actuator groups
with 1 or 8 bits.
With a 1 bit object type, the object value is first
inverted with each push-button action, then
transmitted to the bus, i. e. a "0" becomes a "1", and
when the same push-button is pushed again, a "1"
becomes a "0". The device is thus switched on and off
alternately. This switching behaviour is called
"toggling". An update or change to the 1 bit/1 byte
object value is possible via the bus when another
sensor switches the actuator (e .g. via a two-way
circuit or a central command). To prevent "incorrect"
toggling, you must load the status of the actuator ("1"
or "0") in the push-button. To do this, connect the group
address of the second sensor to the switch/value
object of the multi-function push-button.
For 1 byte object types, you can set two values, which
are transmitted alternately after each press.
Two objects can also be transmitted in any
combination when the push-button is activated (1 bit /
1 byte).

● Dimming
You can use the dimming function for the following:
– Dim brighter and darker via one push-button
(single-button dimming)
– Either dim brighter or darker. You need a second
push-button to dim in the other direction (twobutton dimming).
Additional parameters for single-button dimming
You can dim lighter or darker and also switch on or off
using a single push-button.
The current switching or dimming direction is always
dependent on the previous action, i. e. if switched off,
pressing the push-button briefly will switch the light on
and vice versa, and if the light has been dimmed up,
prolonged actuation of the push-button will dim the
light down again. On release after prolonged actuation,
a stop telegram will be transmitted via the 4 bit
dimming object, thus terminating the dimming
procedure in the dimming actuator.
An update or change to the switch/object value is
possible via the bus when another sensor switches or
dims the actuator (e.g. via a two-way circuit or a central
command). To prevent "incorrect" switching/dimming
activity, you must load the state of the actuator into
the push-button. To do this, connect the group address
of the second sensor to the switch/dimming object of
the multi-function push-button.
A single command is sufficient to cycle through the
dimming range. This dimming procedure can be used
for most applications. The other possible dimming
levels (1/2 - 1/64 brighter or darker) dim brighter or
darker by the selected level. For example, to dim from
min. to max. brightness, you would need to press the
push-button for a prolonged period four times in
succession if the level set is 1/4.
Common parameters for single-button and twobutton dimming
You can use the corresponding push-button to switch
the light on or off (brief press) or dim it (longer press,
the exact period can be parameterised). During
switching, an ON/OFF telegram is transmitted via the
switch object. When dimming, dimming up or
dimming down is carried out via the 4 bit dimming
object; the parameters for the dimming steps can be
set. You can also transmit the corresponding dimming
step cyclically for a period of time which can be set as
required.

Additional parameters for two-button dimming
Communication objects
A single push-button is used to dim either brighter or
darker and switch on or off. A second push-button for
the opposite direction must be parameterised.
You can specify whether a stop telegram is to be
transmitted when the push-button is released. When
you have enabled the transmission of a stop telegram,
a stop telegram will be transmitted via the 4 bit
dimming object after prolonged actuation of the pushbutton, thus terminating the dimming procedure in the
dimming actuator.
A single command is sufficient to cycle through the
dimming range. This dimming procedure can be used
for most applications. The other possible dimming
steps (1/2 - 1/64 brighter or darker) dim brighter or
darker by the selected step. For example, to dim from
min. to max. brightness, you would need to push the
push-button for a prolonged period four times in
succession if the level set is 1/4.

Moving the blind to a pre-specified position
Blind function "up" or "down" with one pushbutton (two-button blind operation)
If the blind actuator is capable of approaching a
specific position, you can define one or two positions
using this function, which can be approached by the
blind using 1 byte position values with a push-button
action. The position values can be set in steps
between 0% and 100%, or infinitely from 0-255.
When approaching a position, the set value for the
blind position and the slat position is transmitted using
a short (or long) push-button action.
To address two positions, enter the required blind
position and slat position for both. Position value 1 is
transmitted with a short push-button action, while
position value 2 is transmitted with a long push-button
action. No movement or stop/step objects exist with
these set parameters.
After the corresponding push-button is pressed for a
short time, a stop/step telegram will be transmitted;
after the push-button is activated for a prolonged
period (the parameters for the exact period can be
set), a movement telegram will be transmitted. With
this function, you must parameterise a second pushbutton with the corresponding settings for blind
movement in the opposite direction. Both pushbuttons must be given the same group addresses.

Direction of movement
Selecting the positioning
The current direction of movement of the blind, or the
direction of the slat adjustment, always depends on
the previous action, i. e. when the blind has just been
moved downwards, it will move upwards the next
time the push-button is activated for a long period
(parameters for the period can be set).
After a stop/step telegram has been transmitted to
adjust the slats, a stop/step telegram for the same
direction of movement can be created by pressing the
push-button again, as long as this subsequent pushbutton action is carried out within a time period, the
parameters for which can be set. If this time period
has elapsed, the direction of rotation of the slats will
change when the push-button is pressed briefly.
The push-button can receive telegrams via the stop/
step movement objects, and can create corresponding
telegrams when the push-button is pressed,
depending on the values received. An update or
change to the switch/object value is possible via the
bus when another sensor switches the actuator (e .g.
via a two-way circuit or a central command). To prevent
"incorrect" movement, you must load the status of the
actuator into the push-button. To do this, connect the
group address of the second sensor to the movement
object of the multi-function push-button.

edge commands
From status feedback object
You can use these edge functions to parameterise
different object actions. You can transmit one or two
objects simultaneously, and select the size of the
objects required (1 bit, 2 bit priority control or 1 byte in
steps or infinitely) as needed. This enables you to
parameterise a large number of application options.
You can specify which actions should be carried out
when a push-button is pressed, and which should be
carried out when a push-button is released. These
actions could include:
– Transmit 1 or 0 (with 1 bit)
– Transmit value 1 or value 2 (with 2 bits or 1 byte):
You can enter two values and set whether and how
they are to be transmitted.
– Transmitting a value:
The object transmits the value which it has currently
been given. You can therefore transfer a value e. g.
with the transmitting group address which was
previously received by another group address.
– Toggling:
The current object value is inverted and then
transmitted. It is therefore alternately switched on
and off (toggled). The value can be modified via the
bus.

– Toggles and is not transmitted:
The toggled value is written into the object and is

current object value is always transmitted cyclically.
– Increases the current object value by [value]
cyclically:
If no cycle time is running, [value] is added to the
current object value, the object value is transmitted,
and a new cycle time is started. If a cycle time is

– Transmits [value] only cyclically:
If no cycle time is running, [value] is transmitted
immediately and a new cycle time is started. If a
cycle time is already running, this is not interrupted,
[value] is transmitted after the current cycle time
has elapsed, and a new cycle time is started.
– Sets object value to [value] (readable only)
[value] is written into the object and is not
transmitted. An active cycle time is terminated.
– Toggles:
compares the current object value with [value]. If
both are the same, value 1 or value 2 is transmitted.
If both are different, [value] is transmitted.
– Toggles, transmits immediately, then cyclically:
The value is toggled (see "toggles") if no cycle time
is running, transmitted immediately and a new cycle
time is started. If a cycle time is already running,
this is interrupted, the toggled value is transmitted
and a new cycle time is started. Subsequently, the
value which has already been toggled is always
transmitted cyclically.
– Toggles, only transmits cyclically:
If no cycle time is running, the toggled value is
transmitted immediately and a new cycle time is
started. If a cycle time is already running, this is not
interrupted, the toggled value is transmitted after
the current cycle time has elapsed, and a new cycle
time is started. Subsequently, the value which has
already been toggled is always transmitted
cyclically.

You can use this function to produce a brief and a long

actuator requires no staircase lighting function for this
request.
With a brief push-button action, the switch actuator
switches on the light, and after a parameterised cycle
time (e. g. 3 minutes), it switches it back off again.
With a long push-button action, the same function is
carried out, but with a longer cycle time (e. g. 6
minutes).

elapsed (here 3 minutes) = transmits 0
Object B: Action on release when the long activation

elapsed (here 6 minutes) = transmits 0
To do this, connect object A and object B with the

Example: Staircase lighting function with cleaning
light function
With a brief push-button action, the switch actuator
switches on the light. A long push-button action
extends the staircase lighting function (= cleaning light
function) until a second, long push-button action
switches off the actuator. The switch actuator requires
a staircase lighting function and a disable function for
this function.

Example: Effect lighting
This example shows you how to program effect
lighting, for example for a display window. A long
push-button action switches between two different
lighting scenes. A short push-button action stops the
toggling and transmits a scene which switches off
everything. The scene module of the multi-function
push-button is used to retrieve the scene.
Number of objects = 2 (object A/B)
Object A/B = 1 byte infinite 0-255
Object A: Direct action when activated = none (stops
cyclical transmission). Action on release before the
long activation time has elapsed = transmits 1. Action
when the long activation time is completed = none
(stops cyclical transmission). Action on release after
the long activation time is completed = none (stops
cyclical transmission). Value 1 = 3.
Object B: Direct action when activated = none (stops
cyclical transmission). Action on release before the
long activation time has elapsed = none (stops cyclical
transmission). Action when the long activation time is
completed = none (stops cyclical transmission). Action
on release after the long activation time has been
completed = toggles cyclically, transmits immediately,
then cyclically. Value 1 = 1, value 2 = 2nd cycle time =
e. g. 1 minute.
To do this, connect object A and object B with the
extension unit object of the scene function.
Example: Switch the light on/off permanently, or
switch off after a cycle time has elapsed
With a brief push-button action, the switch actuator
switches the light on or off permanently. With a long
push-button action, the light switches on, and after a
parameterised cycle time (e .g. 6 minutes), it switches
back off again. Due to the cycle time in the push-button
which can be parameterised, the switch actuator
requires no staircase lighting function for this function.
Number of objects = 2 (object A/B)
Object A/B = 1 bit
Object A: Action on release before the long activation
time has elapsed = toggles
Object B: Action when the long activation time is
completed = transmits 1. After a cycle time has
elapsed (here 6 minutes) = transmits 0. Action on
release when the long activation time is completed =
no change.
To do this, connect object A and object B with the
switch object of the switch actuator.
Example: electronic protection against theft
This example will show you how to program electronic
theft protection for the push-button. It is activated by a
brief push-button action and then transmits cyclically.
As soon as the push-button is forcibly separated from
the flush-mounted module, this can be shown on a
display, or an alarm can be triggered.
Number of objects = 1 (object A)
Object A = 1 bit
Object A: Action on release before the long activation
time has elapsed = transmits 1 immediately and then
cyclically. Action when the long activation time is
completed = no change. Action on release after the
long activation time is completed = no change. Cycle
time = e. g. 10 minutes.
To do this, connect object A with an object expecting
cyclic telegrams (e. g. a safety object). The monitoring
time set on the safety object must be longer than the
cycle time of the push-button. If the safety object
receives no telegrams from the push-button during
this time, a reaction which can be parameterised is
activated (e. g. the channel is switched on).

– Increase the current object value cyclically:
Increase the current object value cyclically by the
parameterised step interval.
– Increase the current object value once:
Increase the current object value once by the
parameterised step interval. An active cycle time is
terminated.
– Reduce the current object value cyclically:
Reduce the current object value cyclically by the
parameterised step interval.
– Reduce the current object value once:
Reduce the current object value once by the
parameterised step interval. An active cycle time is

– Reverse the slide direction and transmit cyclically:
If no cycle time is running, the slide is pushed in the
opposite direction (of this push-button) and a new
cycle time is started. If a cycle time is already
running, it is interrupted, the slide is immediately
pushed in the opposite direction (of this pushbutton) and a new cycle time is started. Cyclic
transmission is stopped when the maximum/
minimum value is reached.
– Reverse the slide direction and cyclically increase/
decrease:
If no cycle time is running, the slide is pushed in the
opposite direction (of this push-button) and a new
cycle time is started. If a cycle time is already
running, it is interrupted, the slide is immediately
pushed in the opposite direction (of this pushbutton) and a new cycle time is started. Cyclic
transmission is not stopped when the maximum/
minimum value is reached. When an incrementing
value reaches the maximum value, the value is set
to the minimum value and cyclic transmission
continues. When an decrementing value reaches
the minimum value, the value is set to the
maximum value and cyclic transmission continues.
– Move step-by-step to the limit values, and then back
again:
The limit values are approached by one step interval
at a time. When a limit is reached, the slide direction
is reversed for the next action.
– Stepwise increment within the limits:
The value is incremented, one step interval at a
time, within the limits. The limits are not exceeded,
the value is set 1 after the last possible step.
Example: Value 1: "0", value 2: "255", step size: "100",
the following values are transmitted:
39%, 78%, 0%, 39%, 78%, 0%, etc.
– Reduce stepwise within the limits:
The value is reduced, one step interval at a time,
within the limits. The limits are not exceeded, the
value is set 2 after the last possible step.
Example: Value 1: "0", value 2: "255", step size:
„100“. The following values are transmitted:
100%, 61%, 22%, 100%, 61%, 22%, etc.

Example: Implementing a "Step dimmer" with
sliding controller function
It is possible to dim a dimmer actuator in several steps
using a push-button on the multi-function push-button.
Example: push-button 1 of the multi-function pushbutton is used as an 8 bit sliding controller. The status
LED can be controlled from the status feedback
object.
1 Set the 8 bit sliding controller in the "push-button 1"
tab of the multi-function push-button.
2 Make the following settings in the tab "Button 1(2)":
Sliding controller function: "with limit values", direct
action when activated: "Stepwise to the limits and
then back again"; action on release or after the long
activation time has been completed: "no change",
value 1: "0", step size: "51"; value 2: „255“. The cycle
time is not required for this function.
3 Connect the push-button value object to the
dimmer actuator value object.
4 Every new press of the push-button sends a new
dimmer value in the steps: 20%, 40%, 60%, 80%,
100%, 80%, 60%, 40%, 20%, 0%, 20%, etc. This
parameter setting implements a stepwise dimmer.

● Scenes
Retrieving scenes by push-button does not access the
internal scene module, but only accesses the bus
externally via communication objects. If you therefore
wish to retrieve scenes stored in the internal scene
module using a push-button, you must connect the
corresponding communication object with the
extension unit object of the scene function.
There are two types of scene function:
– Normal
– Extended
With the standard scene function, a scene is retrieved
by a brief push-button action and a long push-button
action is used to save a scene. Simply set the time
after which a push-button action is detected as a
prolonged operation; how the status LED is to be
triggered must also be set, as must the scene number.

The status LED can

● Parameterising scenes in the scene module
reserved for the alarm function.
The multi-function push-button is fitted with its own
scene module, which enables you to save up to eight
scenes permanently. The saved scenes can be
overwritten if you have parameterised a release for
this purpose.
The entire scene function is controlled via the
extension unit object (1 byte). You also have an object
for programming release, as well as seven 1/8 bit
objects and one object for values up to 16 bits, in order
to transmit scene values to the bus.
You can set the time between the actuator read
telegrams. This makes sense, e. g. when the
anticipated response can last a long time (line coupler,
area coupler).
If a read request is lost, or is not responded to, the
scene from the current object value is saved (either
through a read request, or written via an output). To
check the correct saving procedure, you should
retrieve the scene last saved on the push-button. If this
remains unchanged, the individual saving procedure
has been completed free of errors. If there is a
difference, an incorrect response has been made to a
read request.
If the multi-function push-button works through a
scene, and a further scene is retrieved, the current
process is interrupted and the scene last retrieved is
worked through.

You can parameterise the push-button in such a way
that an alarm is triggered when the specified limits for
the setpoint adjustment on the display are not
reached/exceeded. You can also set the alarm to
triggered when the actual temperature exceeds or fails
to reach a preconfigured value.
You can specify whether an alarm should be displayed
via a flashing display, or whether an acoustic signal
should also be given with 3-gang and 4-gang pushbuttons. For this purpose, you can set the duration of
the alarm (1 to 254 seconds).
● Activating the time control
the fifth scene object is then used for the alarm
function.
Two time-switch channels are available, each with four
programmable switch times, in order to trigger actions
with minute-by-minute precision.
The push-button can be connected to an external clock
via date and time objects, an object to request the
time and an object to identify the working day/holiday,
thus synchronising the internal clock.
After a reset, the time is set to 0:00, and the time
display (time symbol in the display) flashes. When a
synchronisation has been completed (time display is lit
continuously), and it is determined that the difference
between the internal and external clock is less than 1.5
hours, switching commands which are valid for this
period are carried out. If no synchronisation is
completed within 24 hours, switching commands can
continue to be carried out or disabled, depending on
the setting. In this case, the time display also flashes.

Communication objects
How the room temperature controller functions
You can select the following communication objects:
There are many factors which can affect room
temperature. The task of the controller is to detect the
actual temperature constantly, and to ensure that the
heating or cooling system receives new information
accordingly. The heating or cooling system converts
this information and adjusts the room temperature to
the preconfigured setpoints.
The actual temperature is constantly measured by the
temperature sensor integrated into the multi-function
push-button. However, you can also measure the
temperature via an external sensor and transfer it to
the controller via the bus, which then takes it fully or
partially into account when assessing the actual
temperature.
The controller can control the connected heating/
cooling systems via corresponding switch telegrams
or continuous control values. In this way, both PI
controllers and 2-step controls can be parameterised.
Four operation modes (comfort, standby, night and
frost/heat protection) for which setpoints can be set in
each case are available for differentiated control with
different requirements.
Additional functions of the room temperature control
unit are comfort extension, shared/separate control
value output, selection of the operation mode after
reset, offset of the setpoint temperatures, 1 bit/1 byte
status objects, taking into account a temperature
which has been measured separately, temperature
drop detection, and valve protection.

The value 1 (1 bit) switches the clock to
"Working day" mode. The value 0
(1 bit) switches the clock to "Holiday" mode.
Tip: This object should be controlled by an
appropriate year time switch.
If the communication object "Working day/
holiday" does not have a group address then the
default value "0" is used. This means that the
clock is in the "Holiday" mode.
Only the switching times parameterised for "On
holiday" or "Always" are then executed.
Setpoints and operation modes
Four operation modes are available to help you control
the room temperature:
– Comfort mode
Controls the room temperature when the room is
being used.
– Standby operation
Lowers temperature slightly when the room is not
being used.
– Night operation
Lowers temperature significantly, e. g. at night or
during the weekend.
– Frost/heat protection
Automatically switches on the heating or cooling
when temperature threshold values are not reached
or are exceeded.
The additional "comfort extension" operation mode
acts in the same way as the comfort mode, but is
exited automatically after a time period that can be set.
You can switch back and forth between these
operation modes in different ways:
– Via the communication objects, by using the time
control on the multi-function push-button, for
example
– Via the control menu
You can specify a setpoint for each operation mode.
When changing the operation mode, the relevant
● Becoming familiar with and parameterising
room temperature controller
To activate the room temperature controller, you must
switch on the "Controller" parameter in the "General
controller" tab. Up to seven additional tabs, with
setting options, are then available. As for all
parameters, the recommended settings are already
specified here. However, you must check all
parameters to make sure that they are set correctly
and appropriately for the local conditions for your
installation.

Multi-function with 1814/3.1
setpoint for continued room temperature control is
used. The setpoints for all operation modes, except for
frost/heat protection, can be manually altered within
adjustable limits using the control menu on the pushbutton, or can be adjusted via the "Setpoint adjustment
- Controller" object. You can also set whether or not
manual changes to the setpoints should remain valid
after you have switched to another operation mode.
The active operating state of the controller is
determined by the states of the communication
objects: "Comfort", "Night economy", "Frost/heat
protection" and "Dew point alarm".
When calculating the setpoints, the highest priority
goes to the dew point alarm. If the alarm is triggered,
heating continues to be possible, but cooling is
deactivated ("0" on the controller output). The dew
point alarm is terminated when its communication
object is set to "0".
After a reset, the preconfigured operation mode is
active. The corresponding setpoints then also apply. If
the set setpoint is changed manually via the control
menu and an attempt is made to exceed or not reach
the set limits, an acoustic signal may sound with 3gang and 4-gang push-buttons (can be set).
When the offset is received via the bus, the controller
checks whether it lies within the parameterised limits,
and if necessary, adjusts it to the corresponding limits.

Standby operation
The
symbol in the display indicates that the
controller is in the "Standby" operation mode. This
operation mode enables you to reduce or increase the
room temperature to a parameterised level as soon as
the room is no longer in use. A brief heating period or
cooling period is triggered by the low difference in
temperature to the comfort mode.
You can set the controller to switch on automatically in
this state after a reset.
The standby mode is active
– When all operation mode objects equal "0", i. e. the
"Dew point alarm", "Night economy", "Frost/heat
protection" or "Comfort" operation modes are not
active.
– When the "Standby" operation mode is selected in

Example: The upper and lower setpoint adjustment is

values are displayed: 22.0; 21.5; 20.5; 20.0; 19.5; 21.0.
The jump from 19.5 to 21.0 can be explained by the
fact that the cooling setpoint is relevant now because
the actual temperature lies above the setpoint

The same behaviour applies with cooling systems.
The additional level, which is controlled via 2-step
control, remains switched on until a parameterised
interval below the basic level is reached (e. g. 2 K), and
then switches off. Only the basic level then remains
switched on.
Example:
– Setpoint temperature: 21 °C
– Interval between basic level – additional level: 2 K
– Hysteresis of additional level: 1 K
The additional level remains switched on until

The disadvantage of simple control, in contrast to its
advantage, is that the room temperature is not
constant, but changes continuously, reducing comfort
particularly when heating and cooling systems are
slow to react. To counteract this effect, the hysteresis
can accordingly be set small. However, this leads to an
increase in switching frequency, and therefore to
increased wear of the drives.
Controller types
The room temperature control unit transmits control
values to the bus via various communication objects,
which you can use to control different controller types
with switching commands or by specifying percentage
values:
– Continuous 2-step control
– Switching 2-step control
– Continuous PI controller
– Switching PI controller
Continuous and switching 2-step control
2-step control is the simplest type of controller. The
heating switches on as soon as the actual temperature
falls below a specific value, and switches off as soon
as a specific value has been exceeded. The two values
(above and below the setpoint temperature) are called
the hysteresis.

Continuous PI controller
The temperature overshoot above or below the
hysteresis apparent in the diagram is caused when the
heating/cooling system continues to emit heat or cold
into the room after it has been switched off.
For the continuous PI controller, the corresponding 1
byte control value is transmitted 0-100% directly via
the bus to the heating actuator (e. g. EMO valve drive),
which converts the control value directly to a degree of
opening. However, this is only transmitted when the
newly calculated control value has changed by a
specified percentage.
Setting rules for the 2-step control
"Hysteresis of the 2-step control" parameter:
– Small hysteresis:
leads to small fluctuations, but frequent switching.
– Large hysteresis:
leads to big fluctuations, but infrequent switching.

Continuous and switching PI controller
For PI controller, the control value is calculated from a
proportional and an integral proportion. Parameters
such as the temperature difference between the
actual and setpoint, the proportional range and the
readjustment time are material to the calculation. In
this way, the controller can correct the room
temperature quickly and accurately. The corresponding
control value is transferred via a 1 bit/1 byte value to
the bus.
The standard control parameters for the most
common system types are already installed in the
controller:
– Hot water heating
– Underfloor heating
– Electric heating
– Air convector
– Split unit
– Cooling ceiling
You can also set the control parameters for the
proportional range and the readjustment time
manually, but you should know exactly which actuators
are connected and the control conditions in the room.

Switching PI controller (PWM)
With the switching PI controller, also known as the
PWM controller, the control values calculated by the
controller (0-100%) are converted into a pulse-width
modulation (PWM). Within a constant, defined cycle
time, the control actuator is opened ("1") and then
closed again ("0") for the calculated percentage period.
For example, when a control value of 25% is
calculated for a cycle time of 12 minutes, a "1" is
transmitted at the beginning of the cycle time, and a
"0" is transmitted after three minutes (= 25% of 12
minutes)
.

The framework conditions for setting the cycle time
are as follows:
– For small values, the switching frequency and the
bus load are increased.
– For large values, temperature fluctuations are
created in the room.
– A short cycle time for rapid heating systems (e.g.
electric heating).
– A long cycle time for slow heating systems (e. g.
underfloor hot water heating).

Examples
In general:
– Large system increases (e.g. high heating output,
steep characteristic curves for valves) are controlled
with large proportional ranges.
– Slow heating systems (e.g. underfloor heating) are
controlled with high-level readjustment times.
If a satisfactory control result is not achieved by
selecting an appropriate heating or cooling system,
you can improve the adjustment "via control
parameters":
– Low proportional range:
large overshoot for setpoint changes (also
continuous oscillation under certain
circumstances), rapid adjustment to the setpoint.
– Large proportional range:
no (or little) overshooting, but slow adjustment.
– Short readjustment time:
rapid correction of control deviations (ambient
conditions), risk of continuous oscillation.
– Long readjustment time:
slow correction of control deviations.

If you have parameterised the "Heating and cooling"
controller type, either the controller automatically
switches between heating and cooling or it is done by
the "Heating/cooling" object accordingly.
As a standard, switching between heating and cooling
is automatic. The controller is either in heating or
cooling mode. The control value of the non-active
mode is switched to 0% (off).
When switching externally, switch to the heating
mode with a "1" telegram, and to cooling mode with a
"0" telegram.
If the same transmitting group address is used for the
heating and cooling setpoints, the "0" telegrams of the
non-active controller type are automatically
suppressed.

When temperature drop detection is switched on, the
room temperature control unit checks whether the
temperature has fallen by the set temperature
difference within three minutes. If this is the case, the
system switches to frost protection mode for a period
which can be set. After this time has elapsed, the
controller switches the previously set operation mode
back on.
You can set the sensor that takes the temperature to
be measured (internal/external sensor, both or actual
value). When using an external sensor, the actual
temperature consists of the temperature measured on
the room temperature control unit and the external
temperature, depending on the parameterised
weighting (see "Setting the actual value").
Setting the actual value
Here, you can set a correction value (compensation)
for the temperature sensor installed in the room
temperature control unit. This is useful when (it is
mounted in an unsuitable place in the room or where
the temperature is different to other places in the
room (e. g. from a draught or heat sources nearby), for
example. The following formula applies:
Actual temperature = measured temperature +
compensation
You can set the temperature difference (the last
difference transmitted compared to the current actual
value) at which the actual temperature is transmitted,
and at which interval it should automatically be
transmitted (e. g. to visualisation software).
If you also use an external temperature sensor, you
can set the percentage proportion at which the
separately measured temperature should merge with
the current actual value. The external value is received
via the "Current actual value" object, read off by the
room temperature control unit and calculated
according to the set weighting. The actual value object
is then immediately overwritten again with the
calculated actual value.

Setting the control values
This tab only appears when you have set the "cooling",
"heating and cooling" or "2-step heating" control type in
the "Controller general" tab. Here, you can set which
cooling control type should be activated. For PI
controllers, you can select between three standard
system types, for which the recommended
parameters have already been preconfigured.
However, if you have sufficient specialised knowledge,
you can also set the control parameters as required.
For 2-step control, set the hysteresis here.
Please note that different parameters must be set for
different controller types.
For "Cycle time of the switching control values", set the
duration for the PWM controller. The calculated control
value is always transmitted at the start of a cycle time.
If the valve drive has not received a value (e. g. during
commissioning), the room could continuously heat up
or cool down. To prevent this, set the cycle time for
automatic control value transmission. The control
value is transmitted again within the set time (as a
precaution).

Possible solution
The controller switches
constantly between
heating and cooling.
Increase the "dead zone" parameter
between heating and cooling.
The setpoint is only
reached very slowly.
Increase the proportional range, either
by selecting a system type with a larger
proportional range in the system-specific
selection "Adjustment of the controller to
the heating/cooling system", or by
directly increasing the proportional range
via control parameters in the adjustment,
or by reducing the integral time.
The room temperature
exceeds the limits when
changes are made to the
setpoint.
Decrease the proportional range, either
by selecting a system type with a smaller
proportional range in the system-specific
selection "Adjustment of the controller to
the heating/cooling system", or by
directly reducing the proportional range
via control parameters in the adjustment,
or by increasing the integral time.

Setting the valve protection
The valve protection prevents the valves on the
heaters becoming stuck due to deposits in the heating
water when the heating is switched off for a longer
period of time (e. g. over the summer). When the valve
protection is switched on, the valves are opened for a
preset duration (100% on the controller output) after a
preset number of days, and are then closed again (0 %
on the controller output). When the function is
switched on, it is also active during normal controller
operation.

– "A 1" to "A 6" shows the operational status during
the initialisation phase of the push-button. After
approximately 30 seconds, these displays are
replaced by the standard display.
– "Er 1" is an error message and means that the actual

– "Er 2" is also an error message. A contradiction has
been detected in the heating parameters (setpoints
or dead zone are inconsistent).
