TECH EU-R-9z User Manual page 2

Description
Room regulators EU-R-9z are intended to be installed in heating zones.
They send temperature information to EU-L-9 external controller, which
uses the information to control the thermostatic valves (by opening them
when the temperature is too low and closing them when the pre-set room
temperature has been reached).
Current temperature is displayed on the screen. It is also possible to
change the pre-set temperature in a zone permanently or for a period of
time (with time limit).
Controller assets:
• built-in temperature sensor
• wall-mountable cover
• possibility of connecting floor sensor
• screen dimming function - when it is dark in the room, the screen
dims and when it is light, the screen brightens.
• The regulator also has a built-in light intensity sensor, which is
responsible for the brightness of the display. If it's dark in the
room, the screen darkens. When the room brightens - the screen
brightens.
In order to install the regulator it is necessary to plug the sensor cables
in appropriate place.
Communication
button
Mount the EU-R-9z sensor hanger on the wall and next fit the cover.
The following rules must be kept in mind:
- once registered, the regulator cannot be unregistered, but only switched
off in the submenu of a given zone.
- if the user attempts to assign a sensor to the zone to which other sensor
has already been assigned, the fi rst sensor becomes unregistered and it
is replaced by the second one.
- if the user attempts to assign a sensor which has already been assigned
to a diff erent zone, the sensor is unregistered from the fi rst zone and
registered in the new one.
It is possible to set individual pre-set temperature value and weekly
schedule for each room regulator assigned to a given zone. The settings
may be confi gured both in the main menu of EU-L-9 external controller and
via www.emodul.eu (using EU-507 or EU-WiFi RS). The pre-set temperature
may also be adjusted directly from the room sensor using PLUS and
MINUS button.
EU Declaration of conformity
Hereby, we declare under our sole responsibility that EU-R-9z
manufactured by TECH STEROWNIKI, head-quartered in Wieprz Biała
Droga 31, 34-122 Wieprz, is compliant with Directive 2014/35/EU of
the European Parliament and of the Council of 26 February 2014 on
the harmonisation of the laws of Member States relating to the making
available on the market of electrical equipment designed for use within
certain voltage limits (EU OJ L 96, of 29.03.2014, p. 357), Directive
2014/30/EU of the European Parliament and of the Council of 26 February
2014 on the harmonisation of the laws of Member States relating to
electromagnetic compatibility (EU OJ L 96 of 29.03.2014, p.79), Directive
2009/125/EC establishing a framework for the setting of ecodesign
requirements for energy-related products as well as the regulation by
the MINISTRY OF ENTREPRENEURSHIP AND TECHNOLOGY of 24 June
2019 amending the regulation concerning the essential requirements
as regards the restriction of the use of certain hazardous substances in

How to use the controller
1. Light intensity sensor
2. Display - current zone temperature.
3. LED control light.
LED control light flashes - the set temperature has not been reached in the
zone.
LED control light is on - the set temperature has been reached in the zone.
4. PLUS button
5. MINUS button
NOTE
If you touch + and - at the same time, the screen will display current floor
temperature (provided that the floor sensor is connected).
How to register the room regulator in a
given zone:
Each room regulator should be registered in a zone. In order to register,
go to EU-L-9 menu and select Registration in the submenu of a given
zone (Zone / Type of sensor / Wired). After selecting Registration icon
press and hold the button at the back of the room regulator for 2 seconds.
If the registration process has been completed successfully, EU-L-9
screen displays an appropriate message whereas the room sensor screen
displays Scs. If the room sensor displays Err, an error has occurred during
the registration process.
NOTE
Only one room regulator may be assigned to a zone.
How to change the pre-set temperature
The pre-set zone temperature may be adjusted directly from EU-R-9z
room sensor using PLUS and MINUS buttons.
During controller inactivity, the main screen displays current zone
temperature. After pressing PLUS or MINUS, the current temperature
is replaced with the pre-set temperature (the digits are fl ashing). Using
PLUS and MINUS the user may adjust the pre-set temperature value.
After setting desired value wait for 3 seconds – after this time the display
shows a panel to defi ne how long the new setting should apply.
Time settings may be adjusted:
- permanently – press PLUS button until Con appears on the screen
(the pre-set value will apply all the time regardless of schedule settings).
- for a specifi ed number of hours – press PLUS or MINUS until the desired
number of hours appears on the screen e.g. 01h (the pre-set value will
apply for a specifi ed period of time; after that the weekly schedule will
apply).
- if the temperature value defi ned in the weekly schedule settings should
apply, press MINUS until the screen displays OFF.
