  • Page 11 Krok 4. How to configure temperature sensors or a control panel To enable EU-L-9r external controller to control a given zone, it is necessary to provide it with current temperature value. The easiest way is to use temperature sensor EU-C-8r, EU-R-8b or EU-C-mini. If the user wants to be able to change the pre-set temperature value directly from the zone, it is advisable to use EU-R-9b, EU-R-9s or EU-R-9z.

    This function enables the user to activate a given operation mode in the zone.  Normal mode – pre-set temperature depends on the selected schedule.  Holiday mode – the pre-set temperature depends on ‘Temperature settings’ parameter ( Menu > Zones > User’s settings >...

  • Page 18: Time Settings

    This submenu enables the user to configure operation parameters for particular zones. When the pre-set temperature value in a zone is reached, EU-L-9r controller labels the zone as sufficiently heated and the status remains unchanged until the temperature drops below the pre-set temperature by hysteresis value. When the temperature in all the zones is sufficient, the controller disables both the pump and the voltage-free contact.

  • Page 19: Operation Mode

    OPERATION MODE In this submenu, the user can view, edit or set the operation mode in a given zone. It is also possible edit weekly schedules here. The user may set 6 weekly schedules in a given zone: 1 local schedule and 5 global schedules. The schedule temperature settings are common for heating and cooling;...

  • Page 20: Floor Heating

    Select ‘Registration’ in L-9r controller and press the communication button in the selected floor temperature sensor C-8f. If the registration has been successful, the EU-L-9r display will show an appropriate message and the control light on C-8f sensor will flash twice.

  • Page 21: Calibration

    If the floor temperature exceeds the pre-set maximum temperature, the relay will be disconnected and the floor heating will be disabled. The relay will be connected again when the floor temperature drops to the maximum temperature minus hysteresis. Example 2 – Comfort mode: Minimum floor temperature:23°C Hysteresis: 2°C When the floor temperature reaches 23°C, the relay is connected.

Release the button and watch the control light.  the control light flashes twice - successful communication ...

  • Page 23: Sensor Removal

    9.2. SENSOR REMOVAL This function is used to remove the sensors from a given zone. 9.3. INFORMATION After this option has been selected, the display shows information about the actuator version, battery level, range and the actuator opening level (%). 9.4.

  • Page 24: Pump

    1.1. PUMP EU-L-9r controls the pump operation - it enables the pump after the pre-defined delay time if any of the zones has not reached the pre-set temperature. When all the zones reach the pre-set temperature, the pump is disabled.

  • Page 25: Valve Settings

    VALVE SETTINGS EU-L-9r may control an additional valve via a valve module (e.g. i-1m). The regulators connect using RS communication but the registration process is necessary. There is a range of parameters enabling the user to adjust the valve operation to individual needs.

  • Page 26: Valve Type

    Valve stops at 50°C Valve closing 52°C Valve opening 48°C When the pre-set temperature is 50°C and the hysteresis value is 2°C, the valve stops in one position when the temperature of 50°C is reached. When the temperature drops to 48°C, the valve starts opening. When the temperature of 52°C is reached, the valve starts closing in order to reduce the temperature.

  • Page 27: Opening Direction

    4.13. OPENING DIRECTION If, after connecting the valve to the controller, it turns out that it is connected the other way round, then the power supply cables do not have to be switched. Instead, it is enough to change the opening direction in this parameter: LEFT or RIGHT. 4.14.

HUMIDITY PROTECTION If the current humidity value is higher than the pre-set maximum humidity (fitter’s menu -> protection - humidity -> Maximum humidity), cooling in the given zone will be disabled. The function is activated for particular zones (Zones -> Zone 1 -> User settings ->...
