CAR/U 4.1.1.1-84 ABB SpaceLogic Room Air Quality Sensor CO2 Humidity Temp Pressure Studio White

The ABB CAR/U4.1.1.1-84 is a high-precision multi-functional room air quality sensor from the SpaceLogic range, purpose-built for integration into professional KNX building automation systems. Housed in an elegant Studio White finish, this Standard Multi-sensor sensor is the ultimate tool for monitoring and maintaining a healthy and comfortable indoor environment in modern commercial and high-end residential buildings.

By consolidating multiple environmental parameters into a single, compact wall-mounted unit, the CAR/U4.1.1.1-84 reduces wall clutter while providing the granular data required by advanced Building Management Systems (BMS) to execute energy-efficient ventilation and climate control strategies. Engineered for longevity and reliability, it utilizes state-of-the-art sensing elements that are factory-calibrated for long-term stability.

The CAR/U4.1.1.1-84 is specifically deployed in environments where indoor air quality (IAQ) is operationally critical. Its sophisticated Studio White finish ensures that technical performance is matched by aesthetic excellence in modern architectural designs.

• In large open-plan office spaces and executive boardrooms, the integrated CO2 and humidity sensing enables demand-controlled ventilation (DCV)
• As occupancy increases and CO2 levels rise, the sensor triggers the BMS to increase fresh air intake, ensuring cognitive performance and health while avoiding energy waste
• In laboratory and healthcare environments, atmospheric pressure monitoring maintains required pressure differentials between rooms, preventing cross-contamination
• Integrated binary inputs allow for direct connection of window contacts, automatically setting back HVAC systems to energy-saving mode when windows are opened
• Essential for energy code compliance and sustainable building operations
