Additional specifications and description
How does it work
This HVAC transmitter measures temperature, relative humidity and ambient light level. Based on the temperature and humidity measurement, the dew point is calculated. All these values are available via Modbus RTU communication. The sensor algorithm can directly control an EC fan, an AC fan speed controller or a damper actuator via Modbus RTU communication. The output value varies proportionally in function of the measured temperature and relative humidity. E.g. as temperature or relative humidity approaches their maximum limit, fan speed will increase or the damper will open.
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 cable - we call it Power over Modbus or PoM. All measured values are available via Modbus RTU communication.
This sensor doesn't require any 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 or relative humidity 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 enclosure offers an IP65 protection against ingress of dust and water. Each sensor is calibrated and tested in our factory. We use sensor elements and components of high quality. This ensures the long-term stability and accuracy of this HVAC transmitter. To ensure optimal performance, it should be protected from direct sunlight.
