I. Safety

Before using the device for the first time the user should read the following regulations carefully.
Not obeying the rules included in this manual may lead to personal injuries or controller damage.

The user’s manual should be stored in a safe place for further reference. In order to avoid

accidents and errors it should be ensured that every person using the device has familiarized
themselves with the principle of operation as well as security functions of the controller. If the
device is to be sold or put in a different place, make sure that the user’s manual is there with the
device so that any potential user has access to essential information about the device.
The manufacturer does not accept responsibility for any injuries or damage resulting from
negligence; therefore, users are obliged to take the necessary safety measures listed in this
manual to protect their lives and property.

WARNING

 The device should be installed by a qualified electrician.

 The regulator should not be operated by children.

WARNING

 Any use other than specified by the manufacturer is forbidden.
 Before and during the heating season, the controller should be checked for condition of its

cables. The user should also check if the controller is properly mounted and clean it if dusty
or dirty.

Care for the natural environment is our priority. Being aware of the fact that
we manufacture electronic devices obligates us to dispose of used elements
and electronic equipment in a manner which is safe for nature. As a result,
the company has received a registry number assigned by the Main Inspector
of Environmental Protection. The symbol of a crossed out rubbish bin on a
product means that the product must not be thrown out to ordinary waste
bins. By segregating waste intended for recycling, we help protect the natural
environment. It is the user's responsibility to transfer waste electrical and
electronic equipment to the selected collection point for recycling of waste
generated from electronic and electrical equipment.

II. Description of the device

EU-290 room regulator is intended for controlling the heating device (e.g. gas, oil or electric furnace
or the CH boiler controller). Its main task is to maintain the pre-set temperature in the flat by
sending a signal to the heating device (contact opening) when the desired temperature is reached.

Advanced software enables the regulator to fulfil a wide range of functions:

 maintaining the pre-set room temperature
 manual mode
 day/night program
 weekly control

Controller equipment:

 touch buttons
 front panel made of 3mm glass
 built-in temperature sensor
 batteries

Controller versions:

 v1 – wired, without backlight.
 v2 – wireless, with temporary backlight. It may be optionally equipped with a wireless

external sensor. This controller version cooperates with an additional signal receiver,
installed near the heating device.

 v3 – wired, with temporary backlight.
 v4 – wireless, intended for cooperation with an external controller (e.g. ST-266, ST-268)

III. Installation

The controller should be installed by a qualified person.

EU-290 controller may be installed as a panel mountable on the wall.

III.a) Connection diagrams (v1 and v3 versions)

The room regulator should be connected to the heating device via a two-core cable as illustrated
in the diagrams below:

In the case of wireless connection, the diagrams presented above should be used – the two-core
communication cable should be connected to appropriate sockets in the receiver.

IV. Receiver for wireless controller

EU-290v2 regulator communicates with
the heating device (or the CH boiler
controller) via radio signal sent to the
receiver. The receiver is connected to the
heating device (or CH boiler controller) via
a two-core cable whereas the
communication with the room regulator is
performed wirelessly via radio signal.

The receiver has the following control
lights:

• green 1 – indicates data reception, goes
on during channel change;

• red – indicates receiver operation

• green 2 – goes on when the room temperature fails to reach the pre-set temperature – the

heating device is switched on.

How to change the communication channel

Channel “35” is the default communication channel in the room regulator. The channel may be

easily changed (if the current channel is used by other devices). To change the channel, press
and hold the channel change button for about 10 seconds until the green control light (1) goes
on. Next, change the communication channel in the room regulator following the procedure
described in part VIII.c.10. The green light on the receiver should go off.

V. External temperature sensor

EU-290v2 room regulator may optionally be equipped with an external temperature sensor. The
sensor should be mounted in a shaded place so that it is not affected by the weather conditions.
The current temperature value will be sent to the room regulator every few minutes and it will be
displayed on the main screen.
The external sensor communicates with the room regulator via radio signal. Both the room
regulator and the external sensor are pre-configured to operate on channel “35”, but the user
may easily change the channel (if the current channel is used by other devices).

How to change communication channel:
In order to change the channel, press and hold the channel change button. After the control light
on the sensor flashes, the process of channel change has been initiated. Hold the button and wait
until the light starts flashing again. The number of flashes corresponds to the first digit of the
desired channel number.
Release the button after the desired number of flashes and press it again to set the second digit
of the channel number – the control light flashes quickly twice. Hold the button and wait until the
light flashes the desired number of times. When the button is released, the control light flashes
twice – the new communication channel has been set.
NOTE: In case of a one-digit channel number (channels 0÷9) set 0 as the first digit.

Example 1:
28 is the desired communication channel. In order to select this channel, set the first digit - 2,
and the second digit – 8.
Press and hold the channel change button - the control light flashes quickly once - the process of
channel change has been initiated. Hold the button and wait until the light flashes two more times
(the first digit of the channel number – 28).
Release the button and press it again – the control light flashes quickly twice – the process of
setting the second digit has been initiated. Hold the button and wait until the light flashes 8 times.
When the button is released, the control light flashes quickly twice – the new communication
channel has been successfully set.

Example 2:
7 is the desired communication channel. In order to select this channel, set the first digit - 0, and
the second digit – 7.
Press and hold the channel change button - the control light flashes quickly once - the process of
channel change has been initiated. As the first digit is 0, release the button before the control
light flashes again. Press the button again – the control light flashes quickly twice – the process
of setting the second digit has been initiated. Hold the button and wait until the light flashes 7
times (the second digit of the desired number). When the button is released, the control light
flashes quickly twice – the new communication channel has been successfully set.

In the event of errors in the channel change process, the control light goes on for ca. 2 seconds.
In such a case the channel will not be changed.
