Description

EU-R-8z room regulator is intended for cooperation with EU-L-8 external
controller.
EU-R-8z room regulators are installed in the heating zones. Temperature
information sent by them to the external controller is used to control the
thermostatic valves (by opening them when the room temperature is
too low and closing them when the pre-set room temperature has been
reached).
Current temperature is shown on LED display. The user may also change
the preset temperature permanently or for a limited period of time
directly from the sensor.
Controller equipment:
• LED display
• built-in temperature sensor
• wall-mountable cover
• light sensor

Installation

The controller should be installed by a qualifi ed person.
WARNING
Risk of fatal electric shock from touching live connections.
Before working on the controller switch off the power supply
and prevent it from being accidentally switched on.
WARNING
Incorrect connection of the wires may damage the regulator!
How to register the room regulator in a
particular zone
Each room regulator should be registered in one zone. Enter EU-L-8
external controller menu and select Sensor in the submenu of a given
zone (Zone/Registration/Sensor)- after pressing the Registration icon,
press the communication button in a room regulator placed on the back
of the sensor.If the registration process has been completed successfully,
EU-L-8 controller display shows an appropriate message whereas the
room sensor display shows "Scs". In case of errors in the registration
process, the room sensor display shows "Err".
The following rules must be kept in mind:
- once registered, the sensor cannot be unregistered, but only switched
off in the menu of EU-L-8 external controller by selecting 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-8 external controller (Main menu/
Sensors) and via www.emodul.eu (using ST-507 or WiFi RS). The pre-set
temperature may also be adjusted directly from the room sensor using
PLUS and MINUS button.
Hereby, we declare under our sole responsibility that ST-294 room regulator manufactured by TECH, headquartered in Wieprz Biała Droga 31, 34-122
Wieprz, is compliant with:
• Directive 2014/53/EU of the European parliament and of the Council of 16 April 2014. on the harmonisation of the laws of the Member States
relating to the making available on the market of radio equipment;
• Directive 2009/125/EC establishing a framework for the setting of ecodesign requirements for energy-related products;
• the regulation by the Ministry of Economy of May 8, 2013 'concerning the essential requirements as regards the restriction of the use of certain
hazardous substances in electrical and electronic equipment', implementing provisions of ROHS directive 2011/65/EU
.
For compliance assessment, harmonized standards were used:
PN-EN 60730-2-9 :2011 par. 3.1a Safety of use
ETSI EN 301 489-1 V2.1.1 (2017-02) par.3.1b Electromagnetic compatibility
ETSI EN 301 489-3 V2.1.1 (2017-03) par.3.1 b Electromagnetic compatibility

How to change the pre-set temperature

The pre-set zone temperature may be adjusted directly from R-8z 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 preset 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.
