    I. SAFETY Before operating the device, please read the following instructions carefully. Failure to observe the instructions may cause personal injuries and damage the device. To avoid unnecessary errors and accidents, make sure that all persons operating the device have thoroughly familiarized themselves with the device operation and its safety functions. Please do not discard the manual and please make sure that it remains with the device when it is transferred.

  • Page 6: System Description

    II. SYSTEM DESCRIPTION The EU-ML-12 additional controller is a part of heating control system that enables expansion of the existing installation with additional zones. It has RS 485 and wireless communication. Its primary function is to maintain the preset temperature in each zone.
  • Page 8 An illustrative diagram explaining how to connect and communicate with the remaining equipment: CAUTION If the EU-WiFi RS, EU-505 or EU-WiFi L Internet module is connected to the EU-ML-12, then the emodul.eu application will display only the zones of the respective EU-ML-12 controller. If such a module is connected to...
  • Page 10 Connection between controllers In the case of wired connection between devices: controllers (EU-L-12 and EU-ML-12), room controllers and panel, terminating resistors (jumpers) should be used at the beginning and end of each transmission line. The controller has a built-in terminating resistor, which should be set in the appropriate position: •...
  • Page 11 Connection between the controller and the room controllers When connecting room controllers to the first controller, the jumpers on the controller and on the last of the room controllers are switched to the ON position. If the room controllers are connected to a controller located in the middle of the transmission line, the jumpers to the first and last controllers are switched to the ON position.
  • Page 12 CAUTION If the panel is connected to the EU-ML-12, then this controller must be connected to the main EU-L-12 controller, and this panel must be registered in the following way: Menu → Fitter’s menu → Control panel →...

  • Page 13: First Startup

    Step 4. Configure temperature sensors, room controllers In order for the EU-ML-12 controller to support a given zone, it must receive information about the current temperature. The simplest way is to use a wired or wireless temperature sensor (e.g. EU-C-7p, EU-C-mini, EU-CL-mini, EU-C-8r). However, if you wish to be able to change the set temperature value directly from the zone, you can use either room controllers: e.g.

    4.1.6. ACTUATORS ➢ Settings • SIGMA - the function enables seamless control of the electric actuator. The user can set the minimum and maximum openings of the valve – this means that the degree of opening and closing of the valve will never exceed these values.

  • Page 22: Window Sensors

    4.1.7. WINDOW SENSORS ➢ Settings • ON - The function enables the activation of window sensors in a given zone (window sensor registration required). • Delay Time - This function allows setting the delay time. After the preset delay time, the main controller responds to the opening of the window and blocks heating or cooling in the respective zone.

    ➢ Operation mode • OFF – Selecting this option disables the floor heating mode, i.e. neither Floor Protection Comfort Mode are active. • Floor Protection – This function is used to keep the floor temperature below the set maximum temperature to protect the system from overheating.

  • Page 24: Mixing Valve

    Mixing valve The EU-ML-12 controller can operate an additional valve using a valve module (e.g. EU-i-1m). This valve has RS communication, but it is necessary to carry out the registration process, which will require you to quote the module number located in the rear of its housing, or in the software information screen).
  • Page 25 ➢ Valve Hysteresis - This option is used to set the valve setpoint temperature hysteresis. This is the difference between the preset temperature and the temperature at which the valve will start to close or open. Example: Valve preset temperature: 50°C Hysteresis: 2°C Valve stop: 50°C Valve opening: 48°C...
  • Page 26 CAUTION This setting is not available in the Cooling Return Protection Modes. Heating curve - this is the curve according to which the set temperature of the controller is determined on the basis of the external temperature. In order for the valve to operate properly, the set temperature (downstream the valve) is set for four intermediate external temperatures: -20°C, -10°C, 0°C and 10°C.
  • Page 27 • Room controller function - In this function, it is necessary to set whether the valve will close (Closing) or the temperature will lower (Lowering the room temperature) once it is heated. ➢ Proportionality coefficient – The proportionality coefficient is used to determine the valve stroke. The closer to the set temperature, the smaller the stroke.
  • Page 28 → Always OFF - the pump is switched off permanently and the controller only controls the operation of the valve → Turned ON above the threshold - the pump turns on above the set switching temperature. If the pump is to be switched on above the threshold, the threshold pump switching temperature must also be set.
  • Page 29 Example: Temperature - Set Time Weekly Control Monday ‐ 7 +5°C PRESET ‐ 14 ‐10°C ‐ 22 +7°C In this case, if the temperature set on the valve is 50°C, on Mondays, from 4 to 7 hours ‐ the temperature set on the valve will increase by 5°C, or to 55°C;...

    Voltage-free contact The EU-ML-12 controller will activate the voltage-free contact (after counting down the delay time) when any of the zones has not reached the set temperature (heating – when the zone is underheated, cooling – when the temperature in the zone is too high).

  • Page 33: Pump

    Pump The EU-ML-12 controller controls the pump operation – it switches on the pump (after counting down the delay time) when any of the zones is underheated and when the floor pump option is enabled in the respective zone. When all zones are heated (the set temperature is reached), the controller switches off the pump.
