    SAFETY Before using the device for the first time the user should read the following regulations carefully. Not obeying the rules included in this manual may lead to personal injuries or controller damage. The user’s manual should be stored in a safe place for further reference.
  • Page 5: Device Description

    II. DEVICE DESCRIPTION EU L-8 external controller is intended for both wired and wireless control of the valves (see: Wireless communication). The controller enables significant energy saving due to precise temperature management in particular rooms. Due to advanced software, the controller fulfils a wide range of functions: •...
  • Page 6: First Start-Up

    WARNING The controller may be installed on a DIN strip. IV. FIRST START-UP Follow these step while starting the device for the first time to ensure its failure-free operation: Step 1. Connect L-8 controller with all the devices to be controlled In order to connect the cables, remove the controller cover and connect the cables as indicated on connector labels and diagrams below: All the necessary valve actuators ST-230/2 (connectors 1-8)

  • Page 9 Step 2. Switch on the power supply and check if the devices work properly Once all the devices has been connected, switch on the power supply. Use the Manual mode function to check if each device works properly – use the buttons ▲ and ▼ to select the device and press MENU button - the device should be activated.
  • Page 10 NOTE The user should enable the Internet module to connect with data servers listening on TCP/2000 port. Most computer networks are protected by various software (firewalls, anti-virus software etc.) which may block data exchange with the above mentioned port. If any problems arise, contact technical support or your computer network administrator. Step 4.
  • Page 11 Step 7. Configure the settings for the temperature sensors and the room regulators To enable EU L-8 external controller to control a given zone, it is necessary to provide it with current temperature value. The easiest way is to use C-8r temperature sensor. If the user wants to be able to change the pre-set temperature value directly from the zone, it is advisable to use R-8b, R-8z room regulators.
  • Page 12: Wireless Communication

    V. WIRELESS COMMUNICATION EU L-8 external controller may communicate with certain devices using radio signal: Device Function How to configure The sensor should be Sending current room C-8-r – room temperature registered in the external temperature data sensor controller The sensor should be C- mini - room temperature Sending current room registered in the external...

    FLOOR HEATING 7.1. REGISTRATION Activate Registration option in L-8 external controller and press the communication button in the selected floor temperature sensor C-8f. If the registration has been completed successfully, L-8 display will show an appropriate message and C-8f control light will flash twice to confirm.
  • Page 24: Window Sensors

    Example: Pre-set zone temperature: 23˚C Minimum opening: 30% Maximum opening: 90% Range: 5˚C Hysteresis: 2˚C With the above settings, the valve starts closing if the zone temperature reaches 18˚C (the pre-set value minus range: 23-5). The minimum opening is reached when the zone temperature reaches the pre-set value. After the pre-set value has been reached, the zone temperature starts falling.
