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.

1.1.1. 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.

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.

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).
