Additional specifications and description
Is there sufficient fresh air supply?
This HVAC transmitter offers a clear, visual indication of the CO level via the green, yellow and red LED. The green LED indicates that the CO level is within range - there is sufficient fresh air supply. When the CO level enters the alert range, the yellow LED lights up. Red means: CO out of range or insufficient fresh air supply. The measured temperature, relative humidity and CO level are available via the three analogue outputs and via Modbus RTU. The dew point and ambient light level are available via Modbus RTU.
Reduced installation time
This sensor offers you the choice to connect it via the cage clamp terminals or via the RJ45 connector. This sensor has three analogue outputs. Each of them transmits one of the measured values. E.g. by default, output 1 will transmit 0 V at 0 °C and 10 V at 50 °C. Each output value varies proportionally in function of the measured temperature, humidity, CO or NO2 concentration. The measured temperature is available via output 1, relative humidity via output 2 and CO or NO2 concentration via output 3. All measured values are also available via Modbus RTU.
This sensor doesn't require configuration. Once installed, it is ready to use. The default settings will do for most applications. If necessary, the settings can be adjusted via Modbus RTU. For example, a different output type can be selected to make it compatible with other devices: 0-10 VDC / 0-20 mA / 0-100 % PWM. Also the light intensity of the LEDs for status indication is adjustable. The Modbus register map provides a complete overview of all adjustable settings.
The best quality and reliability
This CO transmitter is manufactured in Europe. Each sensor is calibrated and tested in our factory. In the unlikely event of CO / NO2 sensor element failure, this module can be replaced. We use sensor elements and components of high quality. This ensures the long-term stability and accuracy of this HVAC transmitter. The enclosure offers an IP30 protection against ingress of dust and moisture. It can be mounted on a wall indoors. To ensure optimal performance, it should be protected from direct sunlight.
