ery and technical data, please refer to the installation instructions.
2. Description
The Sensor KNX T-UP gl measures the room temperature. The indoor sensor can
receive an external measured value via the bus and process it with own data to an
overall temperature value (mixed value).
The KNX T-UP gl provides adjustable threshold values. The threshold value outputs
and further communication objects can be linked by AND and OR logic gates.
Additionally, an integrated actuating variable comparator can compare and output
values that are received via communication objects. The sensor has integrated PI
controller for a heating/cooling system.
The device is completed with a frame of the switching series installed in the building
and thus merges with the interior.
Functions:
•Measurement of temperature
•Mixed values from own measured value and external values (proportions can
be set in percentage)

4 Commissioning
Sensor KNX T-UP gl • Version: 05.09.2022 • Technical changes and errors excepted.
•PI controller for heating (one or two step) and cooling (one or two step)
depending on temperature. Control according to separate target values or
basic target temperature
•Threshold values can be adjusted per parameter or via communication
objects: 3 × temperature
•4 AND and 4 OR logic gates with each 4 inputs. Every switching incident as
well as 16 logic inputs in the form of communication objects, may be used as
inputs for the logic gates. The output of each gate may optionally be configured
as 1 bit or 2 x 8 bits
•2 actuating variable comparators for output of minimum, maximum or
average values. Each with 5 inputs (for values received via communication
objects)
3. Commissioning
Configuration is made using the KNX software as of ETS 5. The product file can be
downloaded from the ETS online catalogue and the Elsner Elektronik website on
www.elsner-elektronik.de in the “Service” menu.
After the bus voltage has been applied, the device will enter an initialisation phase
lasting approx. 6 seconds. During this phase no information can be received or sent via
the bus.
3.1. Addressing the equipment
The equipment is delivered with the bus address 15.15.255. Another address can be
programmed using the ETS.
For this purpose there is a button with a control LED on the unit.

Sensor KNX T-UP gl • Version: 05.09.2022 • Technical changes and errors excepted.
5.3. Temperature value
When measuring temperature, the self-heating of the device is considered by the
electronics. The heating is compensated for in the device.
Use Offsets to adjust the readings to be sent.
Permanent measurement variations can be corrected in this way.
The unit can calculate a mixed value from its own reading and an external value. Set
the mixed value calculation if desired. If an external value is used, all of the following
settings are referred to the total value.
The minimum and maximum readings can be saved and sent to the bus. Use the
„Reset temperature min/max. value“ objects to reset the values to the current read-
ings. The values are not retained after a reset.
5.4. Temperature threshold values
Activate the required temperature threshold values. The menus for setting the thresh-
old values are displayed.
5.4.1. Threshold value 1, 2, 3
Threshold value
Set, in which cases threshold values received via object are to be retained. The pa-
rameter is only taken into consideration if the setting via object is activated below.
Please note that the setting "After power supply restoration and programming" should
not be used for the initial start-up, as the factory settings are always used until the first
communication (setting via objects is ignored).
Set the threshold value directly in the application program using parameters, or define
them via the bus using a communication object.

13 Parameter setting
Sensor KNX T-UP gl • Version: 05.09.2022 • Technical changes and errors excepted.
Threshold value setting via parameter:
Set the threshold values and hysteresis directly.
Threshold value setting via a communication object:
Define, how the threshold value is to be received from the bus. Basically, a new value
can be received, or simply a command to increase or decrease.
During initial commissioning, a threshold value must be defined, which will be valid
until the first communication with a new threshold value. For units which have already
been taken into service, the last communicated threshold value can be used. Basically,
a temperature range is given, in which the threshold value can be changed (object val-
ue limit).
A set threshold value will be retained until a new value or a change is transferred. The
current value is saved, so that it is retained in the event of a power supply failure and

Block
The switching output can be blocked using an object.
If the block is activated, define specifications here for the behaviour of the output when
blocked.
The behaviour of the switching output on release is dependent on the value of the pa-
rameter "Switching output sends" (see "Switching output")

5.5. Temperature PI control
Activate the control if you want to use it.
General control
Set, in which cases setpoint values and extension time received via object are to
be retained. The parameter is only taken into consideration if the setting via object is
activated below. Please note that the setting "After power supply restoration and pro-
gramming" should not be used for the initial start-up, as the factory settings are always
used until the 1st communication (setting via objects is ignored).
.
For an adequate regulation of the indoor temperature, comfort, standby, eco and
building protection modes may be used.
Comfort when present,
Standby during short absences,
Eco as a night-time mode and
Frost/heat protection (building protection) during longer absences.
The settings for the temperature control include the set point temperatures for the
individual modes. Objects are used to determine which mode is to be selected. A
change of mode may be triggered manually or automatically (e.g. by a timer, window
contact).
The mode may be switched with two 8 bit objects of different priority. Objects
„... HVAC mode (Prio 2)“ for switching in everyday operation and
„... HVAC mode (Prio 1)“ for central switching with higher priority.
The objects are coded as follows:
0 = Auto
1 = Comfort
2 = Standby
3 = Eco
4 = Building Protection
Alternatively, you can use three objects, with one object switching between eco and
standby mode and the two others activating comfort mode and frost/heat protection
mode respectively. The comfort object blocks the eco/standby object, and the frost/
heat protection object has the highest priority. Objects
„... Mode (1: Eco, 0: Standby)“,
„... comfort activation mode" and
„... frost/heat protection activation mode"
Select the mode to be activated after reset (e.g. power failure, reset of the line via
the bus) (Default).
Then configure a temperature control block via the blocking object.
Use control No • Yes
Switch mode via • two 8 Bit objects (HVAC Modes)

Specify when the current control variables of the controller are to be sent to the bus.
Periodic sending is safer, in case a message does not reach a recipient. You may also
set up periodical monitoring by the actuator with this setting.
The status object reports the current status of the control variables (0% = OFF,
>0% = ON) and may for example be used for visualisation, or to switch off the
heating pump as soon as the heating is switched off.
Then define the type of control. Heating and/or cooling may be controlled in two lev-
els.

General set point values
You may enter separate set point values for each mode or use the comfort set point as
a basic value.
If you are using the controls for both heating and cooling, you may also select the
setting "separately with switching object". Systems used for cooling in the summer
and for heating in the winter can thus be switched from one to the other.
If you are using the basic value, only the deviation from the comfort set point value is
listed for the other modes (e. g., 2°C less for standby mode).
The grades for the set point changes is predefined. Modifications may only remain ac-
tive temporarily (do not save) or remain saved even after voltage recovery (and pro-
gramming). This also applies to a comfort extension.
The control may be manually reset to comfort mode from eco, or night mode. This
allows the user to maintain the daily nominal value for a longer time, e.g. when having
guests. The duration of this comfort extension period is set. After the comfort
extension period is terminated, the system returns to eco mode.
Set point Comfort
Comfort mode is usually used for daytime mode when people are present. A starting
value is defined for the comfort set point as well as a temperature range in which the
nominal value may be modified.
If set point values are entered separately:
Preserve modified set points after mode
change
No • Yes
Setting the nominal values • separate with switching object
• separate without switching object
• with comfort set point as a basis

If the comfort setpoint value is used as a basis:
If the comfort setpoint value is used as a basis, the reduction/increment of the value is
set.
If the comfort setpoint is used as the basis without a switching object, a dead zone is
specified for the control mode "heating and cooling" to avoid direct switching from
heating to cooling.
Standby setpoint
Standby mode is usually used for daytime mode when people are absent.
