Safety instructions

Electrical devices must only be installed and

assembled by a qualied electrician. The

accident prevention recommendations

applicable in the country must be followed.

Failure to follow the installation instructions

may result in damage to the device, re or

other dangers. Please follow the

recommendations and standards applicable for

SELV electrical circuits during installation and

when laying cables. Before any work on the

device or the load, switch off the power to the

installation. Do not forget all the circuit

breakers that deliver voltages which are

potentially dangerous to the device or the load.

Risk of electric shock. The device is not

suitable for disconnection/sectioning. These

instructions are an integral part of the product

and must be kept by the end user.

How to dispose of this product (electrical

and electronic equipment waste). (Applicable

in European Union countries and other

European countries with selective waste

collection systems). This symbol on the product

or its documentation indicates that it must not be

disposed of with other household waste at the end of its

life cycle. As disposing of waste inappropriately may harm

the environment or human health, please separate it from

other types of waste and recycle it responsibly. In this

way you will contribute to the sustainable re-use of

material resources.

Individuals should contact the retailer who sold them the

product or contact their local council to ﬁnd out where

and how they can dispose of this product for recycling in

an environmentally friendly manner. Companies should

contact their suppliers and read the terms of their sales

contract. This product must not be disposed of with the

other commercial waste.

Function

System information

This device is a product of KNX system and

complies with KNX guidelines. Detailed,

specialised knowledge obtained through speciﬁc

KNX training courses is required for full

understanding of the system. The device is

programmed, installed and started up with

certiﬁed KNX software.

ETS start-up

The functions of this device are software- and

conﬁguration-dependent. The application software

is available in the product database. The product

database, technical descriptions and conversion

programmes as well a other up-to-date assistance

software are available on our website.

Easy start-up

The functions of this device are software- and

conﬁguration-dependent. It can also be conﬁgured

a tool speciﬁcally developed for easy set-up and

start-up.

This conﬁguration method is only possible with

devices which are compatible with the Easy

system. The Easy conﬁguration method allows for

simple set-up through a graphic interface.

Preconﬁgured standard functions are assigned to

the in/outputs by means of the conﬁguration tool.

Functional description

The device receives telegrams from the sensors or

other controllers via the KNX installation bus and

switches the valves equipped with electrothermal

motors (actuators) with its 6 triac type outputs.

The triac used at output enables the valves to

switch silently. This product comes in 4 variants

which are distinguished by:

6 heating

outputs

6 heating &

regulation

outputs (t°)

TXM646T TXM646R

TYM646T TYM646R

Typical scenario

• Switching by electrothermal actuators (230 V~

or 24 V~) contact (triac type).

• Integration in the electrical box and rail mounting

according to DIN EN 60715.

• Integration in a hot water distribution cabinet and

installation in a wall mounted box (TGC600

accessory).

Product features

• ON/OFF switch or pulse width modulation

(PWM) mode.

• Compatible with 230 V~ or 24 V~ actuators.

• Possibility of manually controlling outputs on the

device, site mode.

• Product secured against overloading and

short-circuits (see chapter: Meaning of LEDs),

• Valve blocking function,

• Valve failure detection,

• Product power supply failure detection,

• Temperature sensor failure detection: application

of fallback mode.

• Bus connection with the KNX connection

terminals.

Protection against overloading

To protect the device and the connected

actuators, in case of overloading or short-circuit,

the device determines the output concerned.

During this search cycle, the product disables the

output group (C1 + C3 + C5) or (C2 + C4 + C6)

according to the defective outputs. Once

identiﬁed, the latter remain disabled, and the

others return to automatic mode.

Test and start-up

Auto/Manu switch and local command buttons 3

• In switch Manu ( ) position , the buttons 3 5

enable you to control the actuators connected to

the outputs. Pressing once changes the output

status to 0%, pressing twice changes it to 50%

and pressing a third time changes it to 100%.

This cycle is repeated after the 3

rd press.

The cycle time applied manually is

deﬁned at conﬁguration or 20 minutes by

default.

• Use the Switch Auto position in operating 3

mode or to conﬁgure the product.

In switch Auto position , the buttons are 3 5

inactive and the outputs respond to orders from

the KNX bus.

Meaning of LEDs 4

If the product has the temperature

regulation function, you can use the

temperature sensors built in to the

communicating buttons. In this case, for

optimal temperature regulation, it is

recommended to use buttons that are not

equipped with LEDs.

Illuminated physical addressing button 6

Press the illuminated button to physically 6

address the product or check the presence of the

bus (LED lit = bus presence and product physically

addressed).

Assembling the device

Irrespective of the assembly used (in an electrical

box on DIN rail or in a wall mounted box), you

must ensure the device is at the right temperature

with sucient cooling. For wall mounting in a box

outside the electrical cabinet, Hager recommends

the item TGC600.

Image 2: LED operation and status

• upper group: outputs C1 + C3 + C5

• lower group: outputs C2 + C4 + C6

For Hager valves, please refer to the table below:

By output By group

of 3 outputs

Maximum number of

EK723 Valves (230V~) 4 12

Maximum number of

EK724 Valves (24 V~) 4 4

For valves of other brands, please observe the

maximum current consumptions described below.

Typically, a valve's consumption is divided into 3

separate phases:

Depending on the brands, the maximum current

consumptions during these 3 phases, as well as

the length of these 3 phases, vary. You must refer

to the tables below and the valves’ technical sheet

to adjust the size of your installation. You must of

course take into account the most unfavourable

scenario:

230 V ~ valves By output By group of 3 outputs

Max inrush current

t < 200 ms 2.2 A 6.6 A

Max start-up current

200 ms < t < 3 min 30 s 0.6 A 1.8 A

Max current at steady state

t > 3 min 30 s 45 mA 135 mA

24 V ~ valves By output By group of 3 outputs

Max inrush current

t < 200 ms 2.2 A 2.2 A

Max start-up current

200 ms < t < 4 min 30 s 0.9 A 0.9 A

Max current at steady state

t > 4 min 30 s 500 mA 500 mA

The continual overload detection function

built in to the product can detect whether

too many valves are connected to an

output or a group of 3 outputs (see

Protection against overloading).

Start-up

ETS

Loading the physical and application software

address:

• switch on the bus voltage,

• press the programming key,

• load the physical address in the device,

• download the application software to the device,

• note the physical address on the device label,

• stick the label to the device.

If an incorrect ETS application is loaded,

we observe a chase of LEDs C1-C3

C2-C4 C3-C6 in red.
