    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 6: Device Description

    II. DEVICE DESCRIPTION EU-L-9r external controller is intended for controlling valves. 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: • possibility of controlling thermoelectric actuators via 8 room sensors or room regulators EU-C-7p, EU-C-8r, EU-R-8b, EU-C-mini, EU-R-9s, EU-R-9b, EU-R-9z etc.

    OPERATION MODE 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: Registration

    REGISTRATION This function is used to register EU-M-9r room regulator, which enables the user to extend the system to 4 external controllers and be able to control all the zones via the Internet. Follow the steps to register EU-M-9r room regulator: •...

  • Page 19: Pre-Set Temperature

    PRE-SET TEMPERATURE The pre-set temperature in a given zone depends on the settings of the selected operating mode in the zone. As a rule, the temperature results from the currently selected weekly schedule; however, the ‘Pre-set temperature’ function allows the user to set a separate temperature value for a specific period of time or permanently.

    • Schedule settings – this function enables the user to choose the schedule which will apply in a zone (local schedule, global schedule 1-5) during cooling , if the zone operation is based on a schedule. • Constant temperature – this function enables the user to define a separate pre-set temperature that will apply in the zone during cooling, if the zone operation is based on a constant temperature.

  • Page 21: Maximum Temperature

    5.5. MAXIMUM TEMPERATURE Maximum floor temperature is a threshold value of floor temperature. If this value is exceeded, the contact will open (the device is disabled) regardless of current room temperature. 5.6. HYSTERESIS Hysteresis – floor temperature hysteresis defines tolerance for the maximum and minimum temperature. The settings range is 0,1-5°C.

    8.2. VALVE ACTUATORS This option is used to remove the actuators STT-868 , STT-869 or EU-G-X from the controller memory. 8.3. INFORMATION After this option has been selected, the display shows information about the actuator version, battery level, range and the actuator opening level (%).

  • Page 23: Window Sensors

    • Protection - When this function is selected, the external controller monitors the temperature. If the pre-set temperature is exceeded by the value specified in <range> parameter, all actuators in a given zone will be closed (0% opening). This function is active only when sigma function has been activated. •...

  • Page 26: Single Stroke

    4.4. SINGLE STROKE This is the maximum single stroke (opening or closing) that the valve may make during one temperature sampling. The smaller the single stroke, the more precisely the set temperature can be achieved. However, it takes longer for the set temperature to be reached.

  • Page 27: Weather - Based Control

    4.10. WEATHER – BASED CONTROL For the function of weather control to be active, the external sensor mustn't be exposed to sunlight or influenced by the weather conditions. After it is installed in an appropriate place, <Weather-based control> function needs to be activated in the controller menu.

    ON above threshold - the pump is activated above the pre-set activation temperature. If the pump is to be activated above the threshold, the user should also define the threshold temperature of pump activation. The temperature is read from CH sensor. Deactivation threshold*- the pump is enabled below the pre-set deactivation temperature measured on CH sensor.
