Mounting position

If the integrated sensor is used for temperature regulation

(for EK-E12-TP-... versions only), the device has to be

installed preferably lon an internal wall at the height of

1,5 m and at least 0,3 m far from doors. The device can

not be installed close to heat sources such as radiators

or houshold appliances or in position subjected to direct

sunlight. If necessary, for the regulation can be used a

weighted average value between the value measured

by the integrated sensor and a value received via bus by

another KNX device.

Use as a room temperature controller (only for

EK-E12-TP-... versions only)

The pushbutton can be also used as a room temperature

controller for single-stage heating/cooling systems with

radiators, radiant panels and electrical heaters. As the

device has no user interface, it must receive the operatio-

nal parameters by the bus (e.g. operating mode, seasonal

conduction mode or a change of the setpoint value).

Main functional characteristics (room temperature con-

troller)

• Temperature measuring through integrated sensor with

possibility of sending the value on the bus

• 2-point (on/off) or proportional (PWM or continuous)

room temperature regulation

• Seasonal conduction modes: heating and cooling with

possibility of changeover via bus or automatic depen-

ding on the configuration

• Operating modes: comfort, standby, economy and bu-

ilding protection with different setpoint for heating and

cooling

• Automatic switching of the operating modes triggered

by window opening/closing

• Weighted average of two temperature values

• Temperature control alarm

• Anti-locking function for valves (hydronic systems)

Switching, display and connection elements

The device is equipped with four mechanisms for

switching, four LEDs for each channel (for EK-E12-TP-...

versions only), a programming LED and a programming

pushbutton and a terminal block for connection of the bus

line.

Switching elements

• Pushbutton (8) for switching between the normal and

programming operating modes

• One, two or four rockers (4) for independent switching

of single or group of loads

Display elements

• Red LED (7) for indication of the active operating mode

(on = programming, off = normal operation)

• Freely programmable LED with lightguide (5) e.g. for

feedback status and orientation nightlight LED (for EK-

E12-TP-... versions only)

8) Programming pushbutton

Note. Programming pushbutton and LED are ac-

cessible from the front side of the device. It is better

addressing the device before the final assembly of

rockers and frame. Once the addressing has been

performed, the device configuration can be later

downloaded without pressing the programming pu-

shbutton.

Connection of the KNX bus line

The connection of the KNX bus line is made with the ter-

minal block (black/red) included in delivery and inserted

into the slot of the housing.

Characteristics of the KNX terminal block

• spring clamping of conductors

• 4 seats for conductors for each polarity

• terminal suitable for KNX bus cable with single-wire

conductors and diameter between 0.6 and 0.8 mm

• recommended wire stripping approx. 5 mm

• color codification: red = + (positive) bus conductor,

black = – (negative) bus conductor

Warning! The electrical connection of the device

can be carried out only by qualified personnel. The

incorrect installation may result in electric shock or

fire. Before making the electrical connections, make

sure the power supply has been turned off.
