3 Description

Room Temperature Controller KNX eTR 101 • Version: 29.07.2020 • Technical changes and errors excepted.

1. Description

The Room Temperature Controller KNX eTR 101 measures the room temperature

and displays the current value. Via the bus the device can receive an external measured

value and process it with own data to overall temperature value (mixed value).

The KNX eTR 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.

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 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.

4 Installation and commissioning

Room Temperature Controller KNX eTR 101 • Version: 29.07.2020 • Technical changes and errors excepted.

The product conforms with the provisions of EU guidelines.

1.1.1. Accuracy of the measurement

Measurement variations from permanent sources of interference (see chapter

Installation position) can be corrected in the ETS in order to ensure the specified

accuracy of the sensor (offset).

When measuring temperature, the self-heating of the device is compensated.

2. Installation and commissioning

2.1. Installation notes

Installation, testing, operational start-up and troubleshooting should

only be performed by an electrician.

CAUTION!

Live voltage!

There are unprotected live components inside the device.

• National legal regulations are to be followed.

• Ensure that all lines to be assembled are free of voltage and take

precautions against accidental switching on.

• Do not use the device if it is damaged.

• Take the device or system out of service and secure it against

unintentional use, if it can be assumed, that risk-free operation is

no longer guaranteed.

The device is only to be used for the intended purpose described in this manual. Any

improper modification or failure to follow the operating instructions voids any and all

warranty and guarantee claims.

After unpacking the device, check it immediately for possible mechanical damage. If it

has been damaged in transport, inform the supplier immediately.

The device may only be used as a fixed-site installation; that means only when

assembled 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.

5 Installation and commissioning

Room Temperature Controller KNX eTR 101 • Version: 29.07.2020 • Technical changes and errors excepted.

2.2. Installation position

The Room Temperature Controller KNX eTR 101 is made for wall mounting. The

device can be mounted directly on plaster or on a socket (Ø 60 mm).

May be installed and operated in dry interior rooms only.

Avoid condensation.

When selecting an installation location, please ensure that the measurement results

are affected 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).

6 Installation and commissioning

Room Temperature Controller KNX eTR 101 • Version: 29.07.2020 • Technical changes and errors excepted.

2.4. Mounting

Prepare the device

Remove the front panel from the mounting. Release the lock by moving the front panel

a few millimetres upwards. The two parts can then be easily separated (Fig. 4).

Fig. 2: Back view with mounting

4/5 Screw holes for different sockets. Fastening

with 2 screws is sufficient. For wall mounting,

use a fixing material suitable for the ground!

7 Installation and commissioning

Room Temperature Controller KNX eTR 101 • Version: 29.07.2020 • Technical changes and errors excepted.

Screw the mounting onto the wall or socket. The connecting wires (bus line +/-) are led

through the opening in the mounting.

Installation directly on the wall

The wires are pushed into the connection openings.

Installation on a socket

To avoid falsifying the temperature value, use a wind-proof socket and also seal the in-

let pipes against draughts.

Finish mounting

Snap the front panel into place on the mounting (see Fig. 4): Place it slightly above the

centre position, hook it in and slide it downwards.

Fig. 4 Locking of front panel and mounting

Remove the red-black KNX bus terminal, it is not

required.

Connect the bus +/- connecting wires to the spring-

loaded terminals on the front panel.

Fig. 5 Spring-loaded terminals

To pull it out, press the spring down, e.g. with a

screwdriver.

If there is a cavity behind the device, e.g. when

using a socket, you can use the red/black KNX bus

terminal for connection.

8 Addressing the device

Room Temperature Controller KNX eTR 101 • Version: 29.07.2020 • Technical changes and errors excepted.

2.5. Notes on mounting and commissioning

Never expose the device to water (e.g. rain) or dust. This can damage the electronics.

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.

3. Addressing the device

The device is delivered ex works with the bus address 15.15.255. You program a differ-

ent address in the ETS by overwriting the address 15.15.255 or teach the device using

the programming button.

The programming button is located at the bottom outer side of the front panel of the

device and 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 KNX eTR 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.
