IoT-based energy control systems with two-way communication

Aventa has developed a heating regulation based on the estimation of the future heat demand for buildings with floor heating systems. The main controllers, servers and communication systems are wholly designed by Aventa and produced by Norwegian partners.

Thermal stability obtained by the Aventa controller. First floor=bearing wood construction, basement=concrete slab floor construction.
  • Secures energy effective operations, stabile indoor temperatures and personalized monitoring of heat and electricity usage
  • Can be used with or without Aventa’s solar systems

The control system records ambient temperature and solar radiation intensity. Based on these parameters, it calculates future demand for heat in the building. Heat supply is controlled through the regulation of circulation time for the water in the floor system’s heating pipes. The fraction of time that the water circulates – the duty cycle – depends on the calculated heat demand and the temperature of the water in the heating system.

The regulated indoor temperature and a consequent substantial reduction in energy supplied for maintaining comfort, is one important asset of Aventa’s controller. However, the most significant aspect of the product is arguably that it allows for pulsed energy supply to be measured, simply based on the active time (duty cycle) as the main parameter. This method of both controlling and measuring the energy supply opens for utilisation of the technology in applications where many users are connected to a common energy supply system, for example when floor heating is used in building blocks.
