Microprocessor controlled, high-speed adaptive control system for variable control of room supply air and room exhaustair volume flows, particularly suitable for clean rooms and laboratories. Advanced requirements need a heating or cooling, and a pressurization of the room. In addition to these features the multi-functional flow Controller VAV500 provide up to 7 analogue inputs 0 (2) ... 10V DC for connecting consumers (e.g. fume hood controller FC500) and calculates the room balance. In network operation (LON,BACnet, Modbus) up to 16 consumers are accounted for.

The retrofit interfaceboards LON, BACnet or Modbus ensure an individual, efficient and cost-effective direct connection to the building management system (BMS).

Microprocessor controlled, high-speed adaptive control system for variable control of room supply air and room exhaust air volume flows, particularly suitable for clean rooms and laboratories. A high-speed control algorithm compares the setpoint with the actual value measured by a differential pressure transmitter and regulates the flow quickly, precisely and steadily, independent of pressure fluctuations in the duct system. The minimum and maximum volume flow setpoint is freely programmable and is saved mains voltage failure-safe in the EEPROM.

Microprocessor controlled, high-speed volume flow measuring system of room supply air and room exhaust air volume flows in manifolded ducts. Suitable for different measuring tasks, such as fume hoods, safety cabinets and other exhaust air and supply units.

The exhaust air and supply air volume flow is measured very stable and accurate and is as actual analogue value 0 (2) ... 10V DC or in LON-network mode as a standard variable (SNVT) available.

The retrofit interfaceboard LON, BACnet or Modbus ensure an individual, efficient and cost-effective direct connection to the building management system (BMS).

The system data and setpoint values are freely programmable and will be saved voltage fail-safe in the EEPROM.
