The EBC22 is an automatic control with a pressure transducer (XTP) for one or more boilers or other installations where multiple heat sources are connected to the same chimney.
With the help of the XTP sensors, which are installed in the chimney, the low pressure is monitored and maintained by regulating the speed of the chimney fan. The control has inputs and outputs for one or two boilers. With the exodraft ES12 relay box this number can be expanded to up to four boilers.
The EBC22 automatic also offers the possibility of an external entry point for a pressure switch or alarm sensor as well as the possibility of an alarm exit point for example for a building management system.
When the boiler or the heating system starts, a signal is sent to the EBC22 which starts the chimney fan at full speed. When the control receives the signal that the desired chimney vacuum has been reached, a signal is sent to start the boilers burner.
The necessary chimney draft is therefore always guaranteed when you start the boiler, thereby the best and most economical operating conditions are ensured.
If the chimney draft falls below the required level, the speed of the chimney fan is regulated until the required chimney draft is reached.
The EBC22 has an external alarm output for integration into a building management system, etc.
