Elnur Connected for Mattira Boilers - Features

• Elnur Connected is the perfect control system for your new Mattira boiler. Easy to install and set up, the Elnur Connected boiler control system can be operated in the home or from wherever you are by using the purpose designed App on your Smartphone or Tablet.
• This SmartLife Technology is the perfect solution for ultimate home heating efficiency and an ideal choice for houses, apartments, holiday homes and weekend cottages as well as offices, commercial properties and public meeting / community halls.
• All Mattira electric boilers can be limited to any output between 3 and 12 kW on single phase supplies and up to 15 kW on threephase supplies. 
• Heating Modulation: The advanced control board on the boiler will automatically modulate the heating output to the demand required to save energy. This modulating feature of GABARRÓN electric boilers is managed by a Smart Electronic Modulating system (SEM system) which recalculates every 20 seconds in order to regulate the consumption depending on the real heat demand. It applies TRIAC technology combined with an external chrono-thermostat to continuously adapt the heating capacity to the heating needs of the premises, thus achieving 100% energy efficiency and overall savings in energy costs.
• Auto Heating Regulation: Additionally, it is possible to regulate the temperature at which the boiler drives the water heating circuit depending on the outdoor temperature. This method of regulation provides maximum comfort as it anticipates changes in the thermal needs of the house. The room thermostat continues to regulate the temperature inside the house. The connection of an external temperature sensor is required to activate this mode.
• Easy Installation: Gabarron Mattira electric boilers come fitted with all the components required to operate the unit, including a template for ease of installation. Installation is quick and easy and can usually be completed in a single day. 
• 5 Years Guarantee: Your new Gabarron Mattira electric boiler from Elnur is warranted against faulty materials and manufacture defects. This warranty will give you total peace of mind and protection. Full terms and conditions of the warranty are detailed in the manual supplied with the boiler which can also be downloaded from our website - www.elnur.co.uk. The internal unvented hot water cylinder is warranted against faulty materials and manufacture defects for a period of 5 years from the date of purchase. The remainder of components are warranted against faulty materials and manufacture defects for a period of 2 years.
• Compatible with Underfloor Heating: The entire range of GABARRÓN boilers can be used with hot water radiators or with radiant floor or overhead heating. In addition, Mattira boilers can be installed in combination with other heating systems such as thermal solar panels, heat pumps, etc...

Mattira Combi Boilers - Extra Features

• Legionella Protection: The new Mattira Combi Boilers include our “Legionella Protection” system. If this function is activated, the DHW temperature is raised once a week to the maximum allowed, preventing Legionella growth through water temperature control.
• Frost Protection Mode: It is possible to select an anti-freeze mode for frost protection during periods of inactivity. By selecting the frost protection mode, the heating system will activate automatically if the boiler temperature falls under 8ºC.
• Digital Display: Mattira boasts an intuitive and user friendly digital display. The digital display constantly shows the temperature of the circulating heating water and of the domestic hot water tank (DHW) in combi boilers. Heating and DHW are independent modules, this means that we can turn off the heating and only keep the DHW or vice versa. In both displays the keyboard lock can be activated to avoid changes being made. 
• Building Regulations G3 compliant: The Mattira Combi boiler incorporates a 50 litre unvented hot water store to optimise hot water performance. As such, careful consideration to the boiler design has been taken to ensure that the Mattira Combi Boiler incorporates all components and operates in full compliance with G3 of the Building Regulations
• Erp Compliant: The objective is to reduce adverse and greenhouse gas emissions to limit the environmental impacts throughout the life-cycle of a product, with emphasis placed on the design and development stages of a product with a view to improving its energy efficiency.
