3 Safety and operating instructions

Room Temperature Controller Cala KNX T 101 CH • Version: 22.03.2023 • Technical changes and errors excepted.

1. Safety and operating instructions

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 devic-

es 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 un-

intentional switch-on if risk-free operation is no longer guaranteed.

Use the device exclusively for building automation and observe the operating instruc-

tions. Improper use, modifications to the device or failure to observe the operating in-

structions 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 sur-

roundings designated for it.

Elsner Elektronik is not liable for any changes in norms and standards which may occur

after publication of these operating instructions.

For information on installation, maintenance, disposal, scope of deliv-

ery and technical data, please refer to the installation instructions.

2. Description

The Room Temperature Controller Cala KNX T 101 CH measures the room

temperature 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 overall

temperature value (mixed value).

The Cala KNX T 101 CH 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

4 Commissioning

Room Temperature Controller Cala KNX T 101 CH • Version: 22.03.2023 • Technical changes and errors excepted.

•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

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.

After the bus voltage has been applied, the device will enter an initialisation phase last-

ing approx. 5 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.

The programming button can be reached through the opening on the rear of the hous-

ing; it is recessed. Use a thin object to reach the button, e.g. a 1.5 mm² wire.

4. Display and operation at the device

4.1. Adjust room temperature

Depending on the setting of the "Display mode" parameter in the device application,

the Room Temperature Controller Cala KNX T 101 CH 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.

5 Display and operation at the device

Room Temperature Controller Cala KNX T 101 CH • Version: 22.03.2023 • Technical changes and errors excepted.

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

setpoint 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 returns to the

room temperature if no button is touched for 7 seconds.

Tap +:

Increase room temperature

(target temperature is

increased)

Tap -:

Lower room temperature

(target temperature is lowered)

Tap +:

Increase room temperature

(Basic setpoint shift direction

PLUS)

Tap -:

Lower room temperature

(Basic setpoint shift direction

MINUS)

6 Display and operation at the device

Room Temperature Controller Cala KNX T 101 CH • Version: 22.03.2023 • Technical changes and errors excepted.

Touch the + or - button briefly: The current target temperature (or the basic setpoint

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.
