TECH CONTROLLERS EU-R-8b Room Regulator

Product Information

The EU-R-8b room regulator is a device manufactured by TECH company. It is intended for use in heating zones and is designed to cooperate with L-8 external controllers. The temperature information sent by the EU-R-8b to the external controller is used to control the thermostatic valves, opening them when the room temperature is too low and closing them when the pre-set room temperature has been reached. The current temperature is displayed on the main screen and the user can also change the pre-set temperature permanently or for a limited period of time directly from the sensor.

The device comes with a warranty card that guarantees proper operation of the device for a 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. 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 and sales proof (receipt, VAT invoice, etc.).

The EU-R-8b room regulator requires two AAA 1.5V batteries to operate. In case of low battery, the “Lo” message will appear on the screen, indicating that the batteries need to be replaced.

Product Usage Instructions

Safety:
Before using the EU-R-8b room regulator, check its cables for any damage. Also, ensure that the controller is properly mounted and clean it if dusty or dirty.

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.

How to use the controller

1. Display – current zone temperature.
2. MINUS button
3. PLUS button

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).
