Carlo Gavazzi ESCO2THW5VDM is a wall-mounted temperature, humidity and NDIR CO2 transmitter with a 0–5000 ppm CO2 range, 0–10 V analogue outputs, LCD display and RS485 Modbus RTU communication for HVAC and building automation systems.
The Carlo Gavazzi ESCO2THW5VDM is a versatile wall-mounted temperature, relative humidity and carbon dioxide (CO2) transmitter designed for indoor air quality monitoring, HVAC installations and building automation systems. As part of the Carlo Gavazzi ESCO2THW series, it combines three environmental measurements in a single compact device with an integrated LCD display.
The ESCO2THW5VDM measures CO2 concentrations from 0–5000 ppm, temperature from 0–50 °C and relative humidity from 0–100% RH. CO2 measurement uses proven non-dispersive infrared (NDIR) technology, while temperature and humidity are measured using a CMOS sensing element for dependable environmental monitoring.
For integration with building control systems, the ESCO2THW5VDM provides 0–10 V analogue outputs for temperature and CO2 together with RS485 Modbus RTU communication for remote access to temperature, humidity and CO2 measurements. The transmitter operates from 12–36 V DC or 24 V AC and can be configured and monitored using Carlo Gavazzi ESCO2 Soft software.
Temperature, humidity and carbon dioxide levels are important parameters for maintaining comfortable and efficient indoor environments. By measuring all three variables from a single wall-mounted device, the ESCO2THW5VDM provides building management and HVAC controllers with the information required to monitor environmental conditions and implement demand-controlled ventilation strategies.
The combination of 0–10 V analogue outputs and RS485 Modbus RTU provides flexible integration with both conventional and networked control systems. The local LCD display enables occupants and maintenance personnel to view environmental measurements directly, while ESCO2 Soft provides additional configuration, graph plotting and data logging capabilities.
