Installation of the electric heating element (figures, page 3, 4)

CAUTION! Before installing make sure the electric heating element is not connected to the power source. The device must not be switched when it is dry due to the risk of burning or damage of the thermal protection.
CAUTION! Make sure the radiator is filled with water or other heating agent before switching on the electric heating element for the first time!

  • The electric heating element should be connected to the radiator through the bottom outlet or through a previously assembled T-connector as shown in fig. 2.
    CAUTION! The electric heating element must not be held by the cover while assembling/ disassembling.
  • Tighten up the electric heating element with a 22-mm wrench appropriately in order to achieve required airtightness.
  • Rotate the electric heating element cover to the proper direction to set the front of the controller in a desired position – it can be rotated by 330°. The rotation range is limited by a palpable stopper – if it is not possible to rotate the controller in one direction, try rotating in the opposite one.
  • Fill the radiator in with the heating agent up to the required level specified by the manufacturer.
  • Do not fill the radiator in with the heating agent at temperature exceeding 70˚C – there is a risk of thermal fuse damage.                                                                                        CAUTION! Electric heating element is equipped with one time activation thermal fuse (irrecoverable), which is activated when the temperature inside the tube exceed 87˚C. Result activation of thermal fuse: the controller is working but the heating element does not heat. Service is needed in order to reinstate the electric heating element.
    CAUTION! Do not fill the radiator up to 100% of its capacity. An exceeding amount and high temperature of the heating agent in a closed radiator may cause the pressure increase above the maximum value specified by the manufacturer. The maximum pressure of the electric heating element should not exceed 10 atm in order not to impose a threat to your health, life and property.
  • Make sure the radiator is airtight and connect the electric heating element it to the power. Check if the voltage of the wiring complies with the voltage specified on the rating plate. When you find the electric heating element tight, you can connect it to the mains. Check whether the voltage of your home electrical system complies with the voltage provided on the product’s identification plate. Plug the electric heating element in a socket equipped with an earthing pin (PE circuit).
  • The radiator with the electric heating element in the central heating must have supply and return cut-off valves.
  • The electric heating element power cannot exceed the radiator power operating at 75/65/20°C.
      CAUTION! Non-compliance with any of the above safety precautions may impose a threat to your health, life and property.

2. Intended use of device
The electric heating element is an electric device intended solely for installation in radiators (autonomous or connected to the central heating system) used as space heaters, or towel dryers.  The heating agent (liquid heating agent in the radiator) must not cause corrosion or include ethylene glycol, except for the authorised agent applied in central heating systems.

3. Functionality of the electric heating element

  • Dryer. The temperature of the heating agent is adjusted with “+” and “-“ switches: 4 levels from 30 °C to 60 °C
  • Space heater. The temperature of the room is adjusted with “+” and “-“ switches: 8 levels from 17 °C to 24 °C. Functionality is available in the configuration with the external temperature sensor.
  • Controller switches the heating element off when the window is opened. Functionality is available in the configuration with the external open door/ window sensor.
  • Weekly and daily programmer with possibility of setting 3 time zones per day – only in configuration with the mobile application.
  • The dryer mode function with the possibility of setting the operating time:
    – timer „START” – after max 4 hours the electric heating element switches off,
    – timer „TURBO” – after max 4 hours the electric heating element returns to the previous setting,
    – timer „DELAY” – switching the device on with the delay max. 8 hours – operating time max. 4 hours.
  • „HOLIDAY” mode – the possibility to quick decrease set temperature to the lowest level: 17˚C for the room and 30˚C for the radiator – functionality is available in configuration with the mobile application.
  • „Parental control” – the possibility of lock the keyboard from the mobile application.
  • Energy consumption meter – functionality is available in configuration with the mobile application.
  • Intelligent visualisation of operating modes: heating, setting, timer, failure – colourful LED technology.
  • The controller may be rotated by 330°.
  • Intelligent operation control – microprocessor-based control.
  • Protection against agent freezing – Antifreeze function.
  • Three-level thermal protection.
    – the regulation controller prevents the temperature from exceeding 60 °C.
    – in case of an uncontrolled temperature increase, the thermal fuse cuts out the power if any damage of the regulator or temperature sensor occurs.
    – protection of the heating element against “operating in a dry radiator”, meaning operating outside the radiator or operating on the radiator without any heating agent inside. In case of a sudden temperature rise, the electronic system applied in the controller switches off the heating element at 87˚C, above which the single-usage thermal fuse actuates.
  • The application of advanced electronics at the “operating” mode and the electronics of Ultra-Low-Power Technology at the “stand-by” mode provides the low power consumption.
