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, CO, NO2 and ambient light level and the calculated dew point are available via Modbus RTU.
Reduced installation time
One RJ45 connector is all it takes to connect this sensor! Modbus RTU communication and 24 VDC power supply are connected via one UTP cable - we call it Power over Modbus or PoM. All measured values are available via Modbus RTU communication. To facilitate wiring, we recommend to use a Sentera 24 VDC power supply with RJ45 connector. These power supplies offer protection against short circuit, overload and overvoltage. A 24 VDC supply voltage increases the safety and reliability of your installation.
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, the temperature range, the relative humidity range or the CO range can be adjusted via Modbus RTU. 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.
