The cascade controller for boilers from Siemens regulates up to 6 serially connected boilers. It is also used for boiler temperature regulation, heating circuit regulation, and pre-regulation. The controller can be connected to a KNX bus for remote control. Otherwise, control is carried out via a separate control unit.

The controller is designed for the heating parts of ventilation and air conditioning equipment, ventilation and air conditioning applications, and heating systems with their own heat production. The controller is primarily used in commercial buildings and shops, schools, industrial buildings and workshops, but also in residential buildings and houses.
