estc2wv – temperature & co2 2000ppm wall transmitter voltage
Carlo Gavazzi ESTC2WV is a wall-mounted temperature and NDIR CO2 transmitter with a 0–2000 ppm CO2 range, 0–50 °C temperature range and 0–10 V analogue outputs for HVAC and building automation applications.
Why Choose the Carlo Gavazzi ESTC2WV Temperature and CO2 Wall Transmitter?
The Carlo Gavazzi ESTC2WV is a wall-mounted temperature and carbon dioxide (CO2) transmitter designed for indoor air quality monitoring, HVAC control and building automation applications. It combines temperature measurement and NDIR carbon dioxide sensing in a single compact unit, providing two important environmental measurements for ventilation and climate-control systems.
The ESTC2WV measures carbon dioxide concentrations across a 0–2000 ppm range and temperature from 0–50 °C. Both measured variables are available through 0–10 V analogue voltage outputs, allowing straightforward connection to compatible HVAC controllers, PLCs and building management systems.
Designed specifically for wall mounting, the ESTC2WV operates from 8–35 V DC or 12–30 V AC. Its plastic housing provides IP54 protection, with an IP20-rated sensing element, while the compact design makes it suitable for installation in offices, classrooms, meeting areas and other occupied indoor environments.

Temperature and CO2 Monitoring for Building Automation
Temperature and carbon dioxide concentration are valuable measurements for maintaining comfortable indoor environments and controlling ventilation according to actual occupancy conditions. The ESTC2WV combines both measurements in one wall-mounted device, allowing HVAC and building management systems to monitor room temperature alongside CO2 concentration.
Its 0–10 V analogue outputs provide a widely used interface for compatible controllers and analogue input modules. By incorporating CO2 measurement into a demand-controlled ventilation strategy, building systems can regulate fans, dampers and air-handling equipment according to indoor conditions while supporting efficient HVAC operation.
Typical Applications
- Indoor air quality monitoring.
- HVAC temperature and CO2 monitoring.
- Demand-controlled ventilation systems.
- Building management systems.
- Offices and commercial buildings.
- Schools, classrooms and meeting rooms.
- Public and institutional buildings.
- Building automation and environmental control systems.
