    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 4: Device Description

    II. DEVICE DESCRIPTION EU-L-7E external controller is intended for controlling valves. The controller enables significant energy saving due to precise temperature management in particular rooms. Thanks to advanced software the controller fulfils a wide range of functions: • possibility of controlling up to 22 thermostatic actuators via 8 room sensors (C-7p): •...

  • Page 5: Installation

    III. INSTALLATION EU-L-7E controller should be installed by a qualified person. The device is intended to be a free-standing unit or a wall- mountable panel. 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.

  • Page 6: First Start-Up

    In order for the controller to operate correctly, the user must follow these steps when starting the device for the first time Step 1. Connect EU-L-7E controller with the devices Remove the cover and connect the wires following the clues on the connectors and the diagrams presented below.
  • Page 8 Pictorial diagram presenting wiring and communication with other devices in the system: Step 2. Mounting electrolytic capacitors In order to reduce the phenomenon of fluctuation in the temperature read from the zone sensor, use a 220uF / 25V low impedance electrolytic capacitor (GF 220U / 25V SAMXON) connected parallel to the sensor cable. When installing a capacitor, pay special attention to polarization.

    Schedule 1-5 – global schedule These schedules have universal settings for all zones and they cannot be edited in the external controller (to introduce changes it is necessary to use M-7 control panel or connect to the Internet via the Internet module). In order to assign a schedule to a given zone, choose Select option.

  • Page 17: Valve

    VALVE EU-L-7E external controller may control an additional valve via valve module (e.g. ST-431N). The devices communicate using RS communication but it is necessary to register first.  Registration - Configuring particular parameters of additional valve is possible only after it has been properly registered by entering the module number (the number may be found at the back of the control module cover or in Software version submenu).

    X. PROTECTIONS AND ALARMS In order to ensure safe and failure-free operation, the regulator has been equipped with a range of protections. In case of an alarm, a sound signal is activated and the display shows a message informing about the detected problem. Automatic sensor control In the event of temperature sensor damage an alarm is activated informing the user about the type of failure e.g.
