WARRANTY CARD
TECH company ensures to the Buyer proper operation of the device for the
period of 24 months from the date of sale. The Guarantor undertakes to repair
the device free of charge if the defects occurred through the manufacturer’s
fault. The device should be delivered to its manufacturer. Principles of
conduct in the case of a complaint are determined by the Act on specific terms
and conditions of consumer sale and amendments of the Civil Code (Journal of
Laws of 5 September 2002).
CAUTION! THE TEMPERATURE SENSOR CANNOT BE IMMERSED IN ANY LIQUID (OIL
ETC). THIS MAY RESULT IN DAMAGING THE CONTROLLER AND LOSS OF WARRANTY! THE
ACCEPTABLE RELATIVE HUMIDITY OF THE CONTROLLER’S ENVIRONMENT IS 5÷85% REL.H.
WITHOUT THE STEAM CONDENSATION EFFECT.
THE DEVICE IS NOT INTENDED TO BE OPERATED BY CHILDREN.
Activities related to setting and regulation of the controller parameters
described in the Instruction Manual and parts wearing out during normal
operation, such as fuses, are not covered by warranty repairs. The warranty
does not cover damages arising as a result of improper operation or through
the user’s fault, mechanical damage or damage created as a result of fire,
flood, atmospheric discharges, overvoltage or short-circuit. The interference
of an unauthorized service, wilful repairs, modifications and construction
changes cause the loss of Warranty. TECH controllers have protective seals.
Removing a seal results in the loss of Warranty.
The costs of unjustifiable service call to a defect will be borne exclusively
by the buyer. The unjustifiable service call is defined as a call to remove
damages not resulting from the Guarantor’s fault as well as a call considered
unjustifiable by the service after diagnosing the device (e.g. damage of the
equipment through the fault of the client or not subject to Warranty), or if
the device defect occurred for reasons lying beyond the device.
In order to execute the rights arising from this Warranty, the user is
obliged, at his own cost and risk, deliver the device to the Guarantor along
with a correctly filled-in warranty card (containing in particular the sale
date, the seller’s signature and a description of the defect) and sales proof
(receipt, VAT invoice, etc.). The Warranty Card is the only basis for repair
free of charge. The complaint repair time is 14 days.
When the Warranty Card is lost or damaged, the manufacturer does not issue a
duplicate.

negligence; therefore, users are obliged to take the necessary safety measures
listed in this manual to protect their lives and property.
WARNING
- High voltage! Make sure the regulator is disconnected from the mains before performing any activities involving the power supply (plugging cables, installing the device etc.)
- The device should be installed by a qualified electrician.
- Before starting the controller, the user shoud measure earthing resistance of the electric motors as well as the insulation resistance of the cables.
- The regulator should not be operated by children.
WARNING
- The device may be damaged if struck by a lightning. Make sure the plug is disconnected from the power supply during storm.
- 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.
Description
EU-R-8b room regulator is intended for cooperation with L-8 external
controller.
EU-R-8b 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 displayed in the main screen. The user may also change
the pre-set temperature permanently or for a limited period of time directly
from the sensor.
Controller equipment:
- built-in temperature sensor
- wall-mountable cover
Battery low
In case of low battery, the ,,Lo” message will appear on the screen. To ensure
correct operation of the regulator please change the batteries (2xAAA 1,5V)
How to register the room regulator in a particular zone
Each room regulator should be registered in a zone. In order to register, go
to the L-8 menu and select Sensor in the submenu of a given zone
(Zone/Registration/Sensor). After selecting the Register icon, press the
communication button on the back of the room regulator.
If the registration process has been completed successfully, L-8 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 each zone.
How to change the pre-
set temperature
The pre-set zone temperature may be adjusted directly from EU-R-8b 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 flashing). 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 define 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 specified 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 specified period of time; after that the weekly schedule will apply).
– if the temperature value defined in the weekly schedule settings should
apply, press MINUS until the screen displays OFF.
EU Declaration of conformity
Hereby, we declare under our sole responsibility that EU-R-8b manufactured by
TECH STEROWNIKI, head-quartered in Wieprz Biala 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 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 electrical and electronic equipment,
implementing provisions of Directive (EU) 2017/2102 of the European Parliament
and of the Council of 15 November 2017 amending Directive 2011/65/EU on the
restriction of the use of certain hazardous substances in electrical and

How to use the controller
- Display – current zone temperature.
- MINUS button
- PLUS button
- Icon
• flashing – the set temperature has not been reached
• highlighted – the set temperature has been reached
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 first 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
different zone, the sensor is unregistered from the first 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
configured both in the main menu of L-8 external controller (Main
menu/Sensors) and via www.emodul.eu (using EU-505 or
WiFi RS). The pre-set temperature may also be adjusted directly from the room
sensor using PLUS and MINUS button.
