This sophisticated control unit enables collaboration with alternative heat sources such as biomass boiler or the solar system and the simple connection of several boilers in cascade.

The boiler supports intelligent house system Siemens Synco living. It is a comprehensive home automation system with a wide range of devices. The system allows you to control your heating, ventilation and air conditioning units and easily turn on and off electrical appliances. The system also shows you which windows are open, tells you the current outdoor temperature, atmospheric pressure, and provides an easy and convenient way to control lights and blinds. Newly added additional features: simple display of data on consumption of heat, cold, cold and hot water, gas and electricity. Functional equipment Synco living had been extended for reading data on consumption and have them automatically sent to companies that perform cost allocation to individual users. The new feature brings a substantial increase convenience for owners and managers.
