II. DEVICE DESCRIPTION
The EU-292n v2 room regulator is intended for controlling the heating or cooling device (e.g. gas, oil or electric boiler or
the boiler controller).
Its main task is to maintain the pre-set temperature in the flat by sending a signal to the heating/cooling 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
underfloor heating system control (optional; an additional temperature sensor is necessary)
Controller equipment:
touch buttons
front panel made of 1mm glass
built-in temperature sensor
batteries
The EU-292n v2 room regulator offers two display versions:
standard (the data is displayed in black against white background)
negative (the data is displayed in white against black background)
Two colour versions are available:
WHITE
BLACK

The EU-292n v2 works with an additional EU-MW-3 signal
receiver (included in the controller set), mounted near the
heating device.
III. HOW TO INSTALL THE CONTROLLER
NOTE
The device should be installed by a qualified electrician.
The EU-292n v2 room regulator - connection diagram
In order to install the device properly, follow the diagram below. A two-core communication cable should be connected
to appropriate ports in the receiver.

IV. WIRELESS CONTROLLER RECEIVER
The EU-292n v2 regulator communicates with the heating device (or the CH boiler controller) by means of a radio signal
sent to the EU-MW-3 receiver. Such a receiver is connected to the heating device (or the CH boiler controller) by means
of a two-core cable, and communicates with the room regulator using a radio signal.
The receiver has three control lights:
• red control light 1 –it signalises data reception;
• red control light 2 –indicates receiver operation;
• red control light 3 –goes on when the room temperature fails to reach the pre-set value –the heating device is switched
on.
NOTE
In case of no communication (e.g. due to discharged battery), the receiver automatically disables the
heating device after 15 minutes.
Registration of the EU-MW-3 receiver:
1. Press the registration button on the EU-MW-3 receiver.
2. In order to register the relays, select the "Reg" function in the Menu of the EU-292n v2 regulator and hold the
Menu button or press one of the buttons . The message "Scs" means that the registration was successful
while a registration error is signalled with the message "Err". In both cases the registration can be continued by
pressing any button (except EXIT).
The number of registered relays is displayed on the screen. If the regulator has 6 registered relays (maximum
number), it is possible to unregister them and the "Del" message is displayed. Using one of the buttons
select the appropriate option "yes" or "no" depending on whether you want to unregister the relay or not.

V. FIRST START-UP
In order for the EU-292n v2 controller to operate correctly, follow these steps when starting the device for the first
time:
1. Insert the batteries - in order to do it, remove the controller back cover.
2. If the room regulator is to control the floor heating system, connect an additional sensor to the floor sensor
connector.
3. Connect the two-core cable to appropriate sockets in the receiver.
VI. HOW TO USE THE CONTROLLER
1. PRINCIPLE OF OPERATION
The EU-292n v2 room regulator is designed to maintain the pre-set room temperature by sending a signal to the
heating/cooling device (contact opening) when the pre- set room temperature has been reached. After receiving such a
signal, the heating/cooling device is disabled (if it is connected to a CH boiler controller, the CH boiler switches to sustain
mode after receiving the signal).
If the regulator is used in heating mode, it may also cooperate with a floor sensor. In such a situation, the contact remains
closed when the floor temperature is below the minimum threshold. After the threshold temperature has been exceeded,
the contact remains closed until the pre-set room temperature is reached. If the floor sensor temperature exceeds the
maximum value, the controller will open the contact regardless of the current room temperature.
NOTE
For the floor heating functions to be available in the controller menu, an additional sensor must be connected to
the floor sensor contact.
2. OPERATION MODES
The room regulator may operate in one of the following operation modes:
Day/night mode
In this mode the pre-set temperature value depends on the current time of the day. The user may set different
temperature values for the daytime and nighttime (comfort temperature and economical temperature) as well as
define the exact time of entering day mode and night mode.
In order to activate this mode, press EXIT button until day/night mode icon appears on the main screen.

Weekly control
This mode enables the user to define the time when the pre-set comfort temperature and the pre-set economical
temperature will apply. The user may set 9 different programs divided into three groups:
- PROGRAMS 1÷3 –daily temperature values are set for all days of the week;
- PROGRAMS 4÷6 –daily temperature values are set separately for the weekdays (Monday-Friday) and for the
weekend (Saturday-Sunday);
- PROGRAMS 7÷9 –daily temperature values are set for each day of the week separately.
* The display shows the hours when the comfort temperature applies. In the remaining time period economical
temperature applies.
In order to activate this mode, press EXIT until a weekly control icon appears on the main screen.
Manual mode
In this mode the pre-set temperature is adjusted manually from the main screen view with the use of these buttons:
. Manual mode is activated automatically when one of these buttons is pressed. Once the manual mode is
activated, the previous operation mode enters sleep mode until the next pre-programmed temperature change. Manual
mode may be deactivated by pressing EXIT button.
Example 1 –manual mode activation in Day/night mode
When Day/night mode is active, the user changes the pre-set temperature by pressing one of the buttons
which automatically activates manual mode. The controller returns to Day/night mode when daytime changes into
nighttime (or the other way round) or when the user presses EXIT.
