Application Scenarios

The CAR/U4.1.1.1-71 is specifically deployed in environments where indoor air quality (IAQ) is operationally critical. 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 the energy waste of over-ventilating unoccupied zones
  • In laboratory and healthcare environments, the atmospheric pressure monitoring is used to maintain the required pressure differentials between rooms, preventing cross-contamination
  • The integrated binary inputs allow for the direct connection of window contacts, automatically setting back the HVAC system to energy-saving mode when a window is opened — a mandatory strategy for energy code compliance

Its sophisticated Anthracite Grey finish ensures that technical performance is matched by aesthetic excellence in modern architectural designs.
