SHSUCOTL – CO2 & Temperature Sensor with traffic light

Why Choose the Carlo Gavazzi SHSUCOTL CO2 & Temperature Sensor?

The Carlo Gavazzi SHSUCOTL is a Smart Dupline wall-mounted environmental sensor designed to measure indoor CO2 concentration and temperature for intelligent building and HVAC automation. By combining two important indoor-environment measurements in one compact device, it provides building-control systems with information that can be used for ventilation, climate control and indoor air-quality management.

The SHSUCOTL incorporates an RGB LED traffic-light indicator, providing an intuitive visual representation that can be used to communicate CO2 conditions to room occupants. The colour indication makes the device particularly useful in offices, meeting rooms, classrooms and other occupied spaces where users benefit from an immediate visual indication of indoor air quality.

Designed as part of the Carlo Gavazzi Smart Dupline building-automation system, the SHSUCOTL uses a wired fieldbus connection and is powered directly from the bus. Its compact 80 × 90 × 26 mm enclosure is designed for surface wall mounting, providing a discreet environmental sensing solution without requiring a separate local sensor power supply.

Key Advantages

• Combines CO2 and temperature sensing in a single Smart Dupline device.
• Integrated RGB LED traffic-light indication provides clear visual feedback.
• Supports intelligent ventilation and HVAC control based on indoor environmental conditions.
• Smart Dupline bus-powered design eliminates the need for a separate local power supply.

CO2 Monitoring with Traffic-Light Indication

Carbon dioxide concentration is an important indicator for demand-controlled ventilation in occupied buildings. By continuously providing CO2 and temperature information to a compatible Smart Dupline system, the SHSUCOTL can form part of a building-control strategy that adjusts ventilation or other HVAC functions according to actual room conditions rather than relying solely on fixed schedules.

The integrated RGB LED adds local visual feedback to the networked measurements, allowing occupants to recognise changing air-quality conditions without requiring a separate display. Together with its bus-powered Smart Dupline interface, this makes the SHSUCOTL a practical choice for decentralised room monitoring in commercial, educational and residential building-automation installations.

Typical Applications

• Indoor CO2 and air-quality monitoring.
• Demand-controlled ventilation systems.
• Office and meeting-room environmental monitoring.
• Classrooms and educational buildings.
• Commercial building automation.
• HVAC control and optimisation.
• Smart Dupline building-control systems.
• Occupancy-related ventilation strategies.
• Indoor temperature monitoring.
