    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: Description Of The Device

    II. DESCRIPTION OF THE DEVICE The L-4 WiFi controller is intended for controlling the heating device. It controls the heating device and the valve actuators which regulate the water flowing to the maximum of 8 CH zones. The device has a built-in WiFi module enabling the user to view and edit the controller parameters using a mobile app eModul.

  • Page 11: Zones

    ZONES This submenu enables the user to configure operation parameters for particular zones REGISTRATION This function enables the user to register the C-8r, C-mini or CL-mini sensor or the R-8b, R-8bw regulators. It is also possible to register the C-8f floor sensor as a zone sensor. As a consequence, the zone control will be based on floor temperature.

  • Page 12: Pre-Set Temperature

    2.5. PRE-SET TEMPERATURE The pre-set zone temperature depends on the weekly schedule settings. The user may also change this value separately. After the value has been set, the user defines how long the temperature should apply. When the time elapses, the pre- set temperature depends on the weekly schedule again.

  • Page 13: Window Sensors

    Example: Pre-set zone temperature: 23˚C Minimum opening: 30% Maximum opening: 90% Range: 5˚C Hysteresis: 2˚C In the above example, the thermostatic valve starts closing at the temperature of 18˚C (pre-set value minus Range). The minimum opening is reached when the zone temperature reaches the pre-set value. Once the pre-set temperature has been reached, the temperature starts falling.

  • Page 14: Operation Modes

     Settings – This function is used to activate the window sensor (possible after sensor registration) and set the delay time. When the pre-set delay time is over, the main controller sends the information to the actuators forcing them to close.

  • Page 15: Voltage-Free Contact

    - register a wireless additional pump contact (executive module) - switch off a given zone - set up activation delay (if the temperature in a given zone is too low, the contact will be enabled after the delay time). VOLTAGE-FREE CONTACT This function enables the user to register wireless module MW-1.

    VI. SYSTEM CONTROL VIA THE INTERNET The emodul.eu website offers a wide range of possibilities to control the heating system. In order to take full advantage of it, it is necessary to create an account: Once logged in, go to Settings tab and select Register module. Next, enter the code generated by the controller (to generate the code, select Registration in the controller menu).

  • Page 18: Home Tab

    HOME TAB The Home tab displays the main screen with tiles illustrating the current status of particular heating system devices. Tap on the tile to adjust the operation parameters: NOTE „No communication” message means that the communication with the temperature sensor in a given zone has been interrupted.
  • Page 19 The upper value is the current zone temperature whereas the bottom value is the pre-set temperature The pre-set zone temperature depends by default on the weekly schedule settings. Constant temperature mode enables the user to set a separate pre-set temperature value which will apply in the zone regardless of the time. Selecting Constant temperature icon, the user may choose the temperature with time limit.
  • Page 21 Tap on Schedule icon to open up the weekly schedule selection screen: Two types of weekly schedules are available in the controller 1. Local schedule It is a weekly schedule assigned to a particular zone. Once the controller detects the room sensor, the schedule is assigned automatically to the zone.
  • Page 22 After selecting the schedule press OK and move on to edit the weekly schedule settings: Editing each schedule enables the user to define two programs and select days when the programs will be active (e.g. from Monday to Friday and the weekend). The starting point for each program is the pre-set temperature value. For each program the user may define up to 3 time periods when the temperature will be different from the pre-set value.
