Cala KNX T 101
Room Temperature Controller
Technical specifications and installation instructions
Item numbers 70980 (white), 70982 (black)
1. Description
The Room Temperature Controller Cala KNX T 101 measures the room tem-
perature and displays the current value in white illuminated figures. Via the bus the
device can receive an external measured value and process it with own data to ove-
rall temperature value (mixed value).
The Cala KNX T 101 has got an integrated PI controller for a heating and a cooling
system (one or two step). The room temperature is adjusted by means of the „+“
and „-“ touch buttons.
The device is supplemented with a frame of the switch series used in the building,
and thus fits seamlessly into the interior fittings.
Functions:
• Measurement of temperature. Mixed value from own measured value and
external values (proportions can be set in percentage), output of minimum
and maximum values
•Display of the actual value or the target value/basic setpoint shift
•2 touch buttons (+/-) for adjustment of the room temperature
•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
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.
1.0.1. Scope of delivery
• Room temperature controller in casing
• Base plate
Additionally required (not included in the deliverables):
• Windproof device socket according to DIN EN IEC 60670-1 and DIN 49073
• Frame (for insert 55 x 55 mm), compatible to the switch scheme used in the
building
1.1. Technical data
The product is compliant with the provisions of EU Directives.
1.1.1. Accuracy of the measurement
Measurement variations from permanent sources of interference (see chapter Ins-
tallation position) can be corrected in the ETS in order to ensure the specified accu-
racy of the sensor (offset).
When measuring temperature, the self-heating of the device is compensated.
2. Installation and commissioning
Installation, testing, operational start-up and troubleshooting should
only be performed by an authorised electrician.
CAUTION!
Live voltage!
There are unprotected live components inside the device.
• Inspect the device for damage before installation. Only put undamaged
devices into operation.
• Comply with the locally applicable directives, regulations and provisions for
electrical installation.
• Immediately take the device or system out of service and secure it against
unintentional switch-on if risk-free operation is no longer guaranteed.
Use the device exclusively for building automation and observe the operating inst-
ructions. Improper use, modifications to the device or failure to observe the opera-
ting instructions will invalidate any warranty or guarantee claims.
Operate the device only as a fixed-site installation, i.e. only in assembled condition
and after conclusion of all installation and operational start-up tasks, and only in the
surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may
occur after publication of these operating instructions.
2.1. Installation position
The Room Temperature Controller Cala KNX T 101 is installed on a device so-
cket.
May be installed and operated in dry interior rooms only.
When selecting an installation location, ensure that the measurement results are af-
fected as little as possible by external influences. Possible sources of interference
include:
• Direct sunlight
• Drafts from windows and doors
• Draft from ducts which lead from other rooms or from the outside to the
junction box in which the sensor is mounted
• Warming or cooling of the building structure on which the sensor is mounted,
e.g. due to sunlight, heating or cold water pipes
• Connection lines and ducts which lead from warmer or colder areas to the
sensor
Measurement variations from permanent sources of interference can be corrected
in the ETS in order to ensure the specified accuracy of the sensor (offset).
2.2. Device structure
2.2.1. Casing
2.3. Installation of the sensor
First install the windproof socket with feed line. Seal the inlet tubes as well, in order
to prevent draughts.

Room Temperature Controller Cala KNX T 101 2
Room Temperature Controller Cala KNX T 101 • Version: 05.10.2022 • Technical changes and errors excepted. • Elsner Elektronik GmbH • Sohlengrund 16 • 75395 Ostelsheim • Germany • www.elsner-elektronik.de • Technical Service: +49 (0) 7033 / 30945-250
Then screw the base plate to the socket and place the switch program frame. Con-
nect the bus cable +/- to the plug (black-red).
Insert the device firmly onto the metal frame using the catches so that the device
and the housing are fixed together.
3. Commissioning
Never expose the device to water (e.g. rain) or dust. This can damage the electro-
nics. You must not exceed a relative humidity of 95%. Avoid condensation.
After the bus voltage has been applied, the device will enter an initialisation phase
lasting a few seconds. During this phase no information can be received or sent via
the bus.
4. Addressing of the device at the bus
The device is supplied with the bus address 15.15.255. You can program another ad-
dress into the ETS by overwriting the 15.15.255 address or by teaching via the pro-
gramming button.
5. Display and operation at the device
5.1. Adjust room temperature
Depending on the setting of the "Display mode" parameter in the device application,
the Room Temperature Controller Cala KNX T 101 displays the current room
temperature value (or mixed value), the target value or the shift in relation to the
basic setpoint. The display can be dimmed and switched off via the bus so that no
value is displayed.
Option A: Display of actual temperature (room temperature)
The current room temperature is displayed. It is not possible to change the room
temperature manually using the +/- buttons.
Option B: Display of target temperature or basic setpoint shift
Depending on the setting, the current target value or the shift relative to the base
setpoint is displayed. The temperature can be changed by touching the +/- buttons.
Target value display (absolute value):
Display of the basic setpoint shift (change compared to the basic setpoint of the
control):
Option C: Display of actual temperature and target temperature/basic set-
point shift
During normal operation, the current room temperature is displayed. By touching
the buttons, the display jumps to the target temperature or to the basic setpoint
shift, depending on the presetting. Changes with + or - are visible. The display re-
turns to the room temperature if no button is touched for 7 seconds.
Touch the + or - button briefly: The current target temperature (or the basic set-
point shift) is displayed.
Tap +: Increase room temperature
(target temperature/basic setpoint shift is increased).
Tap -: Lower room temperature
(target temperature/basic setpoint shift is lowered).
General:
The step size for the change and the possible setting range are defined in the device
application (ETS). There you can also define whether the manually changed values
are retained after a mode change (e.g. Eco mode overnight) or reset to the stored
values.
The button functions can be locked due to operating mode with priority 1.
6. Maintenance
Ventilation slits must not be dirty of covered. As a rule, it is sufficient to wipe the
device with a soft, dry cloth as required.
7. Disposal
After use, the device must be disposed of in accordance with the legal regulations.
Do not dispose of it with the household waste!
