Carlo Gavazzi ESTC2WVM is a wall-mounted temperature and NDIR CO2 transmitter with a 0–2000 ppm CO2 range, 0–10 V analogue outputs and Modbus RS485 communication for HVAC and building automation applications.
The Carlo Gavazzi ESTC2WVM is a compact wall-mounted temperature and carbon dioxide (CO2) transmitter designed for indoor air-quality monitoring, HVAC control and building automation applications. As part of the Carlo Gavazzi EST environmental sensor series, it combines temperature measurement with NDIR carbon dioxide sensing in a single device for monitoring occupied indoor environments.
The ESTC2WVM measures temperature from 0–50 °C and CO2 concentration from 0–2,000 ppm. Its non-dispersive infrared (NDIR) CO2 sensing technology provides continuous carbon dioxide measurement, enabling HVAC and building management systems to use indoor environmental data for ventilation and climate-control strategies.
This version provides 0–10 V analogue outputs together with Modbus RS485 communication, allowing integration with both conventional analogue controllers and networked building management systems. The ESTC2WVM operates from 8–35 V DC or 12–30 V AC and features a compact wall-mounted enclosure with an M12 connection and IP54 housing protection.
Temperature and carbon dioxide transmitters provide environmental measurements that can be used by HVAC controllers and building management systems to monitor indoor conditions. CO2 concentration is particularly useful as an indicator of occupancy-related ventilation demand, while temperature measurement provides additional information for maintaining comfortable and controlled indoor environments.
The ESTC2WVM combines 0–10 V analogue signalling with Modbus RS485 communication, allowing environmental measurements to be incorporated into both analogue and digital building-control architectures. Its wall-mounted design makes it particularly suitable for monitoring occupied spaces such as offices, classrooms and commercial buildings.
