Description
Introduction
The ABB VC/S4.1.1 is a specialized KNX actuator engineered for individual room climate management across heating and cooling applications. Designed to handle equipment such as radiators, hydronic floor heating systems, and cooling ceilings, this device features four independent channels. Each channel incorporates an electronic valve output suited for thermoelectric valve drives along with an integrated room temperature controller, enabling direct control of room outputs from a single unit. This device is part of our KNX system components range.
For system integrators, electrical consultants, and procurement managers working on KNX building automation projects, precise hardware selection is essential. Given the limited technical dataset for this specific SKU, verifying exact project specifications, channel counts, and sensor requirements against official ABB technical documentation ensures proper BOQ matching and eliminates ordering errors prior to installation.
Key Features
- 4 independent channels dedicated to heating and cooling applications.
- Electronic valve output per channel optimized for thermoelectric valve drives.
- 3 status/monitoring inputs per channel for window, dew point, level, or temperature sensors.
- Direct input compatibility with ABB SAR/A or SAF/A analog room control units.
- Integrated individual room temperature controller built into each channel.
- Full compatibility with the ABB i-bus Tool for advanced diagnosis and commissioning.
Benefits
- Four Independent Channels: Provides control over up to four separate heating or cooling zones within a KNX network.
- Integrated Room Temperature Control: Built-in controllers on each channel eliminate the need for separate room control hardware to command outputs.
- Flexible Room Status Monitoring: Features three inputs per channel to accommodate window contacts, dew point sensors, level sensors, or temperature sensors.
- Analog Control Unit Support: Allows direct connection of one analog room control unit (SAR/A or SAF/A) per channel to support user interface inputs.
- Advanced Tool Support: Fully compatible with the ABB i-bus Tool for simplified commissioning and detailed technical diagnostics.
- Streamlined BOQ Verification: Clear manufacturer SKU (VC/S4.1.1) simplifies procurement alignment for commercial and residential installations.
Applications
Room Temperature Control: Ideal for managing radiator valves, floor heating manifolds, and chilled ceiling systems in commercial offices or residential buildings. Explore more ABB KNX solutions for professional building automation projects.
HVAC Monitoring and Safety: Connects dew point and window sensors directly to channel inputs to optimize climate operation and protect system infrastructure.
Installation Notes
- Wiring and Input Verification: Check signal connections for thermoelectric valve drives and external sensors against official ABB wiring diagrams prior to energizing the bus.
- Commissioning Workflow: Utilize the ABB i-bus Tool alongside standard ETS configuration to perform diagnostics and verify individual channel logic.
- Procurement Check: Cross-reference SKU VC/S4.1.1 with official technical datasheets and the bill of quantities to ensure exact matching of channel count and physical input requirements.
