These typical applications are designed to aid planning and are not to be considered an
exhaustive list.
It can be extended and updated as required.
1.1 Simple motion detector as a light switch
Motion detector theLuxa P300 KNX is installed at a front door of a house and switches a
lamp.
Since the house stands close to the street, passing vehicles should be ignored.
This is achieved by deactivating the motion sensor in the centre via parameter.
As light switch, a channel of the MIX2 switch actuator RMG 8 T is used.

1.2 Cark park lighting with time switch program
The cark park lighting of a company is controlled with a motion detector.
However, the lighting should only be switched on on demand, i.e. when it gets too dark
outside.
For this purpose, the brightness threshold is set to 10 lx
The car park is permanently lit from 4:00 p.m. to 6:00 p.m., as soon as the brightness falls
below the threshold. Motion will not be taken into consideration.
From 6:00 p.m. to 7:00 p.m., the lighting will be switched on for 5 minutes, when someone
enters the car park.
During the remaining time, the lighting will be switched on for 2 minutes when motion is
detected (by taking the brightness into consideration).
These functions are implemented with the alternative time delay and with the integrated time
switch.
In order to cover the entire area, several devices will be used.
One device functions as master in parallel switching (M) and sends the switch commands to
the switch actuator.
The others function as a slave (S1, S2 etc.), and only report detected motion.
The current time and week day can be received e.g. by a Meteodata 140 S GPS weather
station.

1.3 Staircase lighting with standby light
A staircase should be monitored.
The spatial conditions only allow for a monitoring area without gaps by using many motion
detectors.
In order to reduce the expenses, only one detector will be used on each floor, and the
standby function will be used as the warning prior to switch-off.
After the time delay has elapsed, the light will remain switched on for another 5 minutes at a
brightness of 20 % (standby), before it is switched off completely.
With sufficient brightness (daylight), the lighting will remain off.
One device functions as master in parallel switching (M) and sends the switch commands to
the dimming actuator.
The others function as a slave (S1, S2 etc.), and only report detected motion.

2.2 Switching 2-zone internal lighting depending on external
brightness.
The lighting in a hall is divided into 2 zones:
• Zone 1 = Front near to the windows.
• Zone 2 = Rear without windows.
Decreasing external lighting enables the lighting in zone 1 to be turned on later than
in zone 2.
This function is achieved with the help of 2 brightness thresholds and 2 switching
channels.

3.1 Simple shading control
A facade with a number of blinds should be controlled using the following functions:
• Raise at dawn (if lowered manually).
• Lower blinds and set slats to configured position when the preset brightness
threshold is reached.
• Raise all blinds at dusk as well.
• A safety telegram is sent to the actuator in the event of potential frost or storms. This
raises the blinds and prevents unintentional movement as long as the safety hazard
applies.
• Cyclical monitoring of the safety object in the blinds actuator.

4.4 Description
• Objects 0...11 “Actuating Value Channel X“
Input for the actuating value of the particular channel.
Every channel can be connected individually with an ON/OFF or continuous
regulating room thermostat.
The use of the continuous actuating value is recommended thereby.
In this case, it is possible to react more quickly to changes and coupling with a boiler
controller is possible (refer to Object 25).
• Objects 12...23 “Forced Mode Channel X”
A value of 1 on one of these objects puts the related channel into forced operation.
The channel then heats constantly with the fixed actuating value (0...100%) set on
the “Channel X” parameter page.
• Object 24 “Summer Mode”
A value of 1 on this object sets all channels parameterised for it into summer mode
and heating is discontinued.
During summer mode, a valve protection program can be implemented optionally.
The summer mode object cannot be read.
• Object 25 “Highest Actuating Value of all Channels”
This object is available if at least one channel has been parameterised as a
continuous controller.
The actuating values of the channels are permanently compared with each other and
the currently highest value is always sent to this object.
In this way, the current heat demand of the system can always be transmitted to the
heating boiler which can adapt its capacity exactly to the true demand.
For every channel, it is possible to select individually whether or not it should be
taken into account for the calculation of the maximum actuating value. In this way,
rooms to be ignored for the heat demand can remain out of consideration.
Page 32 of 202
• Objects 26...37 “Timeout of Actuating Value signal Channel 1...12“
Only available if cyclical monitoring of the actuating value of the room thermostat has
been selected for the associated channel.
If the monitoring is selected, the channel must receive an actuating value telegram
regularly from the room thermostat. Recommendation: To guarantee fault-free
operation, the cyclical sending time of the room thermostat should not amount to
more than half of the monitoring time.
Example: Monitoring time 30min, cyclical sending time of the thermostat at least
every 15 min.
If a new actuating value is not received within the parameterised monitoring time, a
failure of the room thermostat will be assumed and an emergency program with a
fixed actuating value (0 ... 100%) will be started.
This function can be selected or deactivated individually for every channel.
The monitoring time is set for all channels together on the “General” page.

Remark:
The standard values for the actuating value limitation are set to 10% and 90%.
The minimum value of 10% enables faster reaction capability of the thermal
connected valves during heating requirement.
A maximum value of 90% preserves the connected valves without restricting the
heating power.
In this way, their lifetime will be extended significantly.

5.2 Description of objects
•
Objects 80, 90, 160, 170 """" Switching ON/OFF"
A 1 on this object dims up to 100%,
and 0 dims to 0%
•
Objects 81, 91, 161, 171 "brighter/darker"“
This object is actuated with 4-bit telegrams (EIS 2 relative dimming).
This function can be used to dim the light up or down in increments (with 1...64
increments)
.
In the standard application, telegrams are sent with 64 increments.
IMPORTANT: The response to 4-bit telegrams depends on the
“Switching On/Off with a 4-bit telegram” parameter.
•
Objects 82, 92, 162, 172 "Dimming value"
This object can be used to select the desired dimmer setting directly.
Format: 1 byte percentage value EIS 2 dimming, value.
0 = 0%
255 = 100%
•
Objects 83, 93, 163, 173 "Soft switching"
A “1” on this object starts a soft switching cycle, i.e.:
The brightness is gradually increased, starting from the minimum brightness.
The dimming value remains constant for the programmed time and is then gradually
reduced after this time has elapsed.
Once the programmed minimum brightness has been reached the dimming value is
reset to 0%.
The cycle can be extended or prematurely terminated via telegrams.
This sequence can also be controlled using a time switch if the "Time between soft
ON and soft OFF" parameter is set to "Until soft OFF telegram".
The dimming cycle is then started with a “1” and finished with a “0”.
Page 42 of 202
•
Objects 84, 94, 164, 174 "Compulsory operation = 1" / "Compulsory
operation = 0" / "Compulsory operation via dimming value"
The function of the compulsory operation object can be configured as a 1-bit or 1byte object.

Object 240 "Central continuous On"
This object is a central object. It can be configured to work on all channels.
If this object is set to "1" all of the channels "participating" in this object are dimmed
"Participate" object to 100%.
If this object is set to "0" it does not effect the channels.
•
Object 241 "Central continuous Off"“
This object is a central object. It can be configured to work on all channels.
If this object is set to "1" all of the channels "participating" in this object are dimmed
"Participate" object to 0%.
If this object is set to "0" it does not effect the channels.
•
Object 242 "Central switching"
This object is a central object. It can be configured to work on all channels.
If a "1" or "0" is sent to this object then this is the same as if a "1" or "0" is sent to the
switching objects of the channels (Object 80, Object 90, ...). The same functionality
could also be achieved by connecting all switching objects to the same group as that
of this object.
Accordingly, using this object saves time during the assignment of the group
addresses and also saves on the number of associations.
Page 47 of 202
•
Object 243 "Call/save central scenes"“
This object can be used to save and subsequently call "scenes".
The save process stores the current status of the dimming channel, regardless of
how the status was brought about (e.g. via dimming values, switching commands,
central objects or the manual switches).
The saved status is thus restored when called up.
Each channel can participate in a maximum of 8 scenes.
The following telegrams need to be sent in order to call or save scenes:

Each channel saves its current
dimming value in the scene
memory with the sent scene
number, provided the channel is
intended to participate in this
scene.
This scene memory remains alive
even after bus failure or mains
failure.
Each channel adopts the dimming
value stored in the scene memory
under the sent scene memory,
provided the channel is intended to
take part in this scene.

A float switch is connected to the input terminals of I1.
The input I1 controls a channel of the switch actuator RME 8 S, to which an optical or
acoustical signalling device is connected.
An acknowledgement push button is connected to input I2, which can send the
acknowledgement telegram to the acknowledgement object of I1.
The alert can be terminated with the acknowledgement push button under the following
conditions:
• Permanently: As soon as the trigger is not present anymore (water level dropped).
• Temporarily: During persistent fault (e.g. water level too high).

9.2 School location : HMG 6 T as heating controller with automatic
summer mode.
The HMG 6 T basic module controls the heating in 6 classrooms.
The room temperature is determined by an Amun 716* CO2 sensor.
The HVAC operating mode is controlled centrally by a timer.
If a window is opened, control changes to the frost protection mode.
The comfort mode is activated by a presence button.
To save energy costs, control should change over to the summer mode automatically when
the weather is mild.
This is achieved with the aid of a Meteodata 139 weather data receiver.

These typical applications are designed to aid planning and are not to be considered
an exhaustive list.
It can be extended and updated as required.
10.1
Basic switching, simple blind control
The push button interface TA 4 controls the blinds actuator JMG 4 T.
1 single push button is connected to the push button interface TA 4 for each set of
blinds (single-surface operation).
Depending on whether the push buttons are pressed for a short or long time, the
push button interface sends an up/down or step/stop telegram.
The blinds should be raised in the evenings and remain open at night.
For this purpose the timer TR 648 top2 RC is programmed in such a way that
channel 1 sends an Off telegram (astro-pulse) to the central UP/DOWN object.

In this example, for simplicity, the focus is on the sun position tracking.
For this reason, all other comfort functions such as
heating/cooling support, etc. are deliberately not listed here.
The weather station Meteodata 140 controls the lamella tilt in accordance with the
sun position.
This helps achieve optimal light incidence without direct solar radiation.
The blinds should be raised when there is a danger of frost. The object Central safety
frost is involved in this.

Bedroom lighting
The light should not be blinding when switching on at night, otherwise it should light up
immediately at 100%.
All dimming values should, however, be configurable via the dimming function:
• At night the switch-on value should not exceed the 40% limit
• Dimming up to 100% should be possible however (e.g. when reading)
• No restrictions during the day
• Dimming via 2 buttons

Switching HVAC operating modes
The TR 648 top2 KNX is to take over the changing of HVAC operating modes in an
office building.
The thermostat is set to standby mode in the morning via the clock switch switch.
The room is only heated to comfort mode if it is actually occupied.
This function is assumed by a presence detector.
The thermostat is reset to night temperature reduction in the evenings and at the the
weekend.
If a window is opened (RAM 713 S, window contact to E1), the thermostat switches
to frost protection mode.

15.1
The school environment: Heating with presence detector
and frost protection via window contact.
15.1.1
Description
RAM 712 controls one or more actuators.
Once someone enters the room the RAM 712 changes to comfort mode, otherwise it
operates in standby mode during the day and in night time mode at night.
If a window is opened RAM 712 automatically changes to frost protection mode
A presence detector is used for presence recognition.
The presence telegram is only sent after a switch-on delay so that the heating is not
activated if the room is only occupied for a short time.
All windows are fitted with window contacts. These are connected with input 1 on
RAM 712.
The window status is sent via a common group address to the window position input
object.
RAM 712 will recognise when a window is opened and automatically switch to frost
protection mode. When the window is closed the previously set operating mode will
be restored.

Heating and cooling in the 2 wire system
The following points must be observed for use in a 2 wire heating/cooling system:
•
In the 2 wire system, heating and cooling mediums (depending on the season)
are –lead through the same lines and controlled via the same valve.
Über einen Parameter können The cooling control variable and the heating
control variable can be sent via a parameter to a single, common object
(Object 7) - (see parameter: Output of cooling control variable, chapter on
cooling control)
•
It is also possible to connect the "heating control variable" and "cooling
control variable" objects to the positioning actuator via the same group
address.
•
The control variables must not be sent cyclically
•
The switchover between heating and cooling mediums is performed by the
system and must therefore be passed on to the room thermostat.
The parameter "Switching between heating and cooling" (Parameter page
"Cooling control") is set to "via object". The heating/cooling system must send
a 0 for heating mode and a 1 for cooling mode to Object 15 "Switching
between heating and cooling" in the RAM 713.
Page 146 of 202
16.1.3
Frost protection via window contact
A window contact should cause automatic switching to frost protection mode (heat
protection mode).
A contact is mounted on the window. This is connected directly to an input of the
external interface, E1 for instance.
The device is programmed as follows:
“Operating mode” parameter page
The corresponding switch object (Object 9 for E1) is linked with Object 5 (window
position) via the group address.
RAM 713 S will recognise when the window opens and automatically switch to frost
protection mode (heat protection mode). When the window is closed the previously
set operating mode will be restored. See also New operating modes.

Determining the current set point value
The current set point value can be adapted in line with certain requirements by
selecting the operating mode.
The operating mode can be specified by Objects 3…5.
There are two methods available:
18.1.1
New operating modes
If on the parameter page “operating mode”, new operating mode is selected by the "
Objects to select operating mode" parameter, the current operating mode can be
defined as follows:

Typical application: In the mornings Object 3 activates "Standby" or "Comfort"
mode and in the evenings "Night" mode via a timer (e.g. TR 648).
During holiday periods, Object 3 also selects frost / heat protection via another
channel of the timer.
Object 4 is connected to a presence indicator. If a presence is detected, Cheops
control switches to Comfort mode (see Table).
Object 5 is connected to a window contact. As soon as a window is opened, Cheops
control switches to frost protection mode.
Page 158 of 202
18.1.2
Old operating modes
If on the parameter page, old operating mode is selected by the " Objects to select
operating mode" parameter, the current operating mode can be defined as follows:

Typical application: In the mornings "Standby" mode and in the evenings "Night"
mode is activated via a timer.
During holiday periods, Object 5 selects frost / heat protection via another channel on
the timer.
Object 4 is connected to a presence indicator. If a presence is detected, Cheops
control switches to Comfort mode (see Table).
Object 5 is connected to a window contact. As soon as a window is opened, Cheops
control switches to frost protection mode.
The old method has two advantages over the new method:
1. To switch from Comfort to Night operating mode, 2 telegrams (2 timer
channels if necessary) are required.
Object 4 must be set to 0 and object 3 to 1.
2. If during periods when "Frost / heat protection" is selected via the timer, the
window is opened and then closed again, the "Frost / heat protection" mode is
cleared.

18.1.3
Set point value calculations
Assuming the current operating mode, the current set point value of Cheops control
is calculated as follows:
A distinction is drawn between whether heating or cooling operation is currently
required.

The set point value has previously been increased by one step using the red key (1
keystroke)
Calculation:
Current set point value
= basic set point value + set point value offset
= 21°C + 1K
= 22°C
If operation is switched to standby mode, the current set point value is calculated as
follows:
Current set point value = basic set point value + set point value offset - reduction in
standby mode
= 21°C +1K -2K
= 20°C

Example:
Cooling in comfort mode.
The room temperature is too high and Cheops control has switched to cooling
operation
Calculation:
Current set point value
zone
= basic set point value + set point value offset + dead
= 21°C -1K +2K
= 22°C
Changing to standby mode causes a further increase in the set point value (energy
saving) and gives rise to the following set point value.
Set point value = basic set point value + set point value offset + dead zone +
increase in
standby mode
= 21°C - 1K + 2K + 2K
= 24°C
Page 162 of 202
18.2
Set point value offset
The current set point value on Cheops control can be adapted in 3 ways:
•
step by step by the red (+) and the blue (-) key
•
in increments via Object 5 " adjustment of set point temperature "
•
directly via Object 1 " Manual shift of set point value "
The differential between the set point value offset and the Basic set point value is
sent by Object 1 at each change (e.g. -1.00).
The offset limits are specified on the "Operation" parameter page by the "Maximum
set point value offset" parameter and apply for all 3 types of set point value offset.
This parameter indicates the maximum permitted offset and the increment per
keystroke (or per activation of Object 6).
18.2.1
Incremental set point temperature adjustment via keys
Each time the blue key is pressed, the set point value is decreased by one increment.
Each time the red key is pressed, the set point value is decreased by one increment.
When the max. permitted offset is reached, further keystrokes have no effect.
18.2.2
Incremental set point temperature adjustment via Object 6
Each time a 1 is sent to Object 6, the set point value is decreased by one increment.
Each time a 0 is sent to Object 6, the set point value is increased by one increment.
When the max. permitted offset is reached, further send actions have no effect.
Page 163 of 202
18.2.3
Direct set point temperature adjustment via Object 1
In this case, the set point value is changed by sending the desired offset to Object 1.
This involves the differential (may be preceded by a minus sign) being sent in EIS5
format.
The offset always relates to the programmed and not to the current set point value.
Example – Basic set point value 21°C:
If a value of 2.00 is sent to Object 1, the new set point value is calculated as follows:
21°C + 2,00K = 23.00°C.
To then bring the set point value to 22°C, the differential is resent to the programmed
basic set point value (here 21°C), in this case 1.00K (21°C+1.00K=22°C)
18.3
External interface
The external interface consists of inputs E1 and E2.
Both inputs are routed through the Cheops connection line.
The use of these inputs (presence sensor or actual value) is specified on the
"Settings" parameter page.
The inputs themselves are configured on the "External interface" parameter page.

Input E2
E2 as binary input:
A presence indicator, switch or key can be directly connected here
If a presence indicator (or switch) is used, the period of comfort mode is determined
by the indicator, i.e. comfort mode remains in force for as long as presence is
indicated.
If a presence key is used, operation switches without time limit from standby to
comfort mode when presence is indicated.
If presence is indicated during night operation, comfort mode is activated for a limited
time.
Because the presence key is often not reset when the room is vacated, the presence
input is automatically reset when the defined operating mode is changed, so that a
night reduction, for example, can take place.
The selection between key and indicator is made on the "Operating mode" parameter
page.
The type of presence contact can be set on the "External interface" parameter page.
•
E2 as analogue input for an external sensor
With this configuration, all settings are made on the "Actual value" parameter side.
An external sensor (Order No. 907 0 191) is connected to E2.
The maximum permitted line length is 10m.
Important:
If E2 is declared as actual value input, the "Input for actual value" selection cannot be
changed on the "Actual value" parameter page.
Page 166 of 202
18.4
Monitoring the actual value
18.4.1
Application
Case 1: A sensor is connected to interface E2.
Its connection line could be inadvertently interrupted or short-circuited, e.g. during
building or renovation work.
Case 2: The temperature is determined by a different EIB device and sent to Cheops
control.
This external temperature transmitter could fail (bus line short circuited etc…) and not
longer be able to perform its function, for a short time or permanently.
Because control is not possible if the actual value fails, this value must be monitored.
18.4.2
Principle
If an external sensor is connected to E2, it is constantly monitored for short-circuit or
line break.
If the temperature is received via Object 2, Cheops control can monitor whether new
actual value telegrams are received at regular intervals.
In both cases, either an emergency program can be started or further control can be
handled by the internal sensor, should the actual value fail.
Page 167 of 202
18.4.3
Practice
The response is defined as follows on the "Actual value" parameter page:
•
External sensor on E2
Emergency program (0…100%)
or internal measurement:
•
Receive actual value via Object 2
First the monitoring period must be defined.
This should be at least double the cycle time of the temperature transmitter (e.g. if
the temperature is sent to Cheops control every 5 minutes, the monitoring period
must be at least 10 minutes).
The response to the actual value failure can then be programmed as above.
Emergency program (0…100%)
or internal measurement:
Important recommendation:
Rooms can cool down dramatically when the outdoor temperature is low. This may
cause radiators to freeze. To prevent this from happening, you must not select a too
low position in the emergency program.
A value of ≥ 30% is recommended.

Valves and valve seals
18.5.1
Valve structure
Valve seat
Tappet
Rubber seal
18.5.2
Valves and valve seals
When idle, i.e. tappet not actuated, the tappet is pushed outwards by the spring and
the valve opens (100% with normal effect).
When the tappet is pushed, the rubber seal is pressed into the valve seat and the
valve closes (0% position with normal effect).
The valve does not close immediately on touching the valve seat, depending on the
characteristics, the existing tappet may have to move onwards until the valve is fully
closed.
This response depends on the hardness, shape, aging or damage to the valve seal.
To correct the influence of this parameter, Cheops allows an additional pressing of
the valve seal to be entered (see also Troubleshooting).
Caution: In order to avoid seal damage, the value should be increased by max.
10 increments.
Page 169 of 202
18.6
Limit of actuating value
To control the temperature, Cheops control sets an actuating value of between 0%
and 100%.
For practical reasons, it is not usually necessary to use the entire bandwidth of
between 0% and 100%).
18.6.1
Minimum actuating value
The unpleasant whistling noise that some valves can generate at low actuating value,
can be avoided by specifying a minimum actuating value.
If, for instance, this response is determined at below 8%, a minimum actuating value
of 10% is specified.
On receipt of a actuating value below the specified limit value, Cheops control can
respond in one of 2 ways ("Response on under-running the minimum actuating value
in heating operation"):
•
Either move to immediately to 0% ("0%")
•
or stop at the position of the minimum actuating value and do not close valve
completely until actuating value 0% is received (0%=0% otherwise minimum
actuating value)
Page 170 of 202
18.7
Determine the maximum actuating value
18.7.1
Application
If within a system all valve actuators are only slightly open, e.g. one at 5%, one at
12%, another at 7% etc., the heating boiler can reduce its output because only a
small amount of heating energy is required.
In order to guarantee this, the heating boiler requires the following information:
How high is the actuating value in the room, which currently exhibits the greatest heat
requirement?
With Cheops valve actuators, this task is handled by the "Maximum position"
function.
18.7.2
Principle
The actuating values are constantly compared between all participants (Cheops
valve actuators). Those participant with a higher actuating value than the one
received may send it, those with a smaller one may not.
In order to accelerate the process, the greater the difference between its own and the
received actuating value, the greater the speed at which the valve actuator sends.
Thus, the valve actuator with the highest actuating value sends first and beats the
remainders.
Page 171 of 202
18.7.3
Practice
The actuating value comparison takes place via Object 3 ("Maximum position") where
for each valve actuator, a common group address for the maximum position is placed
on Object 3.
In order to start the actuating value comparison between the participants, one (and
only one) participant must send a value to this group address cyclically.
This task can be handled by either boiler or valve actuator.
If it is the boiler, it must send the smallest possible value, i.e. 0%.
If it is a Cheops valve actuator, the parameter " Transmission of object
"Max. actuating value"(for boiler control)" on parameter page " Security and forced
mode” must be set to any cycle time.
This valve actuator then regularly sends its own actuating value and the others can
respond accordingly.
Irrespective of which participants act as initiator, the "Transm. of object “max.
actuating value” (for heating system)" must be set to the default value for all other
valve actuators, see Figure:
18.8 2
step heating
A 2-step heating system consists of a slow main step and a fast additional step.
Typically, Cheops control is plugged into the floor heating system (main step) and the
radiators are controlled as the additional step.
Cheops controls the two steps in parallel, the additional step being controlled at a
lower set point value.
The differential between main and additional step is defined on the "Set point value"
parameter page.
Cheops drive valve actuators can be used as a continuous additional step
(recommended).
Thermal valve actuators (Order No. 907 0 248) or possibly an electrical additional
heater can be used as a switching additional step.

Temperature control
18.9.1
Introduction
Cheops Control can be used as a P or a PI controller, although the PI control is
always preferred.
With the proportional control (P control), the actuating value is rigidly adjusted to the
temperature differential.
The proportional integral control (PI control) is far more flexible, i.e. controls more
quickly and more accurately.
To explain the function of both temperature controls, the following example compares
the room to be heated with a vessel.
The filling level of the vessel denotes the room temperature.
The water supply denotes the radiator output.
The heat loss from the room is illustrated by a drain.
In our example, the maximum supply volume is 4 litres per minute and also denotes
the maximum radiator output.
This maximum output is achieved with an actuating value of 100%.
Accordingly, at an actuating value of 50%, only half the water volume, i.e. 2 litres per
minute would flow into our vessel.
The bandwidth is 4l.
This means that the controller will send an actuating value of 100% while the actual
value is smaller than or equal to (211 – 41) 171.
Function:
•
•
•
•
Desired filling quantity:
21 litres (= set point value)
From when should the supply flow gradually be reduced in order to avoid an
overflow? :
4l below the desired filling volume, i.e. at 21l – 41 = 171 (=bandwidth)
Original filling volume
15l (=actual value)
The losses amount to 1l/minute

A filling volume of 15l gives rise to a control deviation of 211 – 151 = 61
Because our actual value lies outside the bandwidth, the control will control the flow
at 100%
i.e. at 4l / minute
The supply quantity (actuating value) is calculated from the control deviation
(set point value – actual value) and the bandwidth.
Actuating value = (control deviation / bandwidth) x 100
The table below shows the response and therefore also the limits of the P-control

The last line indicates that the filling level cannot increase any further, because the
flow allows only the same amount of water to flow in as can flow out through loss.
The result is a permanent control deviation of 11 and the set point value can never
be reached.
If the loss was 1l higher, the permanent control deviation would increase by the same
amount and the filling level would never exceed the 19l mark.
Page 174 of 202
P-control as temperature control
The P-control behaves during heating control as shown in the previous example.
The set point temperature (21oC) can never quite be reached.
The permanent control deviation increases as the heat loss increases and as the
ambient temperature decreases.
18.9.3
Response of the PI-control
Unlike the pure P-control, the PI-control works dynamically.
With this type of control, the actuating value will not remain unchanged, even at
constant deviation.
In the first instant, the PI-control sends the same actuating value as the P-control,
although the longer the set point value is not reached, the more this value increases.
This increases is time-controlled over the integration time.
With this calculation method, the actuating value does not change if the set point
value and the actual value are the same.
Our example, therefore, shows equivalent in and outflow.
Notes on temperature control:
Effective control depends on agreement of bandwidth and integration time with the
room to be heated.
The bandwidth influences the increment of the actuating value change:
Large bandwidth = finer increment on actuating value change.
The integration time influences the response time to temperature changes:
Long integration time = slow response.
Poor agreement can result in either the set point value being exceeded (overshoot)
or the control taking too long to reach the set point value.
Usually, the best results are achieved with the standard settings or the settings via
system type.

Combined with 5 RAM 712 Varia controls 6 rooms (rooms 1-6), with window contacts
and presence detectors, via a HMT 6 with thermal actuators.
In room 1 (monitoring room) the window contacts and the presence sensors are
connected to a TA 2.
Here, VARIA controls the room temperature and monitors the window status in all
rooms.
In each of the rooms 2 to 6, room temperature is controlled by a RAM 712.
The window contacts and presence sensors are connected to the binary inputs on
the RAM 712.
All window objects send their status to a line on display page 1,
which can be configured as a favourite page.
All window objects are also centrally linked to the Varia favourite page object.
If a window is opened in a room, the favourite page containing the window display
status is displayed (only VARIA 826 S KNX).
Alternatively, a signal can be activated as soon as a window is opened.
The only other requirement is to connect object 120 with same group addresses as
object 121.
