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 specifi c 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 fi re, fl ood, atmospheric discharges, overvoltage or short-circuit. The interference of an unauthorized service, wilful repairs, modifi cations 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 unjustifi able service call to a defect will be borne exclusively by the buyer. The unjustifi able service call is defi ned as a call to remove damages not resulting from the Guarantor’s fault as well as a call considered unjustifi able 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.

Description

EU-R-8bw room regulator is intended for cooperation with EU-L-8 external controller. EU-R-8bw 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
• air humidity 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 EU-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, EU-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-8bw 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.

How to use the controller

1. Display – current zone temperature
2. MINUS button
3. PLUS button
4.  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 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 EU-505 or WiFi RS). The pre-set temperature may also be adjusted directly from the room sensor using PLUS and MINUS button.
