Control 8000 – easily expandable

with function modules

The Control 8000 architecture is modular and extremely flexible. The functions of the control device Connecting a Bosch CHP module via the
can be expanded with different modules, thereby fulfilling to all your requirements. The device can Modbus RTU interface
easily integrate up to four modules. ▶ Simple, quick and secure integration into
the control concept
▶ Request and release CHP unit via Modbus
▶ Display CHP module operating messages,
SI – Safety equipment ▶ Communication of Control 8000 with heating boilers
For connecting up to five external safety devices – via an Ethernet interface warnings or fault messages
e.g. to fulfill DIN EN 12828: ▶ Communication with energy management system ▶ Automatical adjustment of individual
▶ Minimum and maximum pressure limiter can be (EMS) heat sources via EMS BUS parameters

▶ General 4-pole input (can be named individually) MW – Integration of heating circuit and DHW
▶ Four 2-pole programmable inputs (can be named functions
individually) For integrating heating circuit and DHW functions.
▶ Fault analysis and detection of the triggered safety When controlling a heating circuit with or without
