Belimo VRU-M1-BAC Technical Data Sheet

VAV-Universal, modular control solution with
integrated Δp sensor for contaminated media.
Can be combined with damper actuator
optimally suited to the VAV/pressure duct
application. Field of application: technical
building equipment, HVAC systems
• Application: VAV/CAV units or duct pressure
control in comfort areas and areas with
contaminated air
• Belimo M1, static diaphragm sensor
• Functional range differential pressure 0...600
Pa
• suitable for ...-VST actuator
• Control communicative, hybrid, modulating
(0/2...10 V)
• Communication via BACnet MS/TP, Modbus
RTU or Belimo MP-Bus
• Conversion of sensor signals
• Tool connection: Service socket, NFC interface
