Temperature | humidity controller wall mounting, PoM


Product description

Room temperature humidity controller with Modbus RTU communication. It measures temperature, relative humidity and ambient light level. Based on the measured values, the dew point is calculated. The supply voltage is 24 VDC PoM - this means that Modbus RTU communication and 24 VDC power supply can be connected via one RJ45 connector. The sensor algorithm can directly control an EC fan, an AC fan speed controller or a damper actuator via Modbus RTU communication. All measurements and the output value are available via Modbus RTU. In many applications, the ambient light sensor can be used to control the ventilation system in function of the occupancy of the room. All settings can be adjusted via Modbus RTU. Also the light intensity of the LEDs for status indication is adjustable.

Additional specifications and description

  
Is the temperature OK?
This HVAC transmitter offers a clear, visual indication of the temperature via the green, yellow and red LED. The green LED indicates that temperature is within range. When the temperature enters the alert range, the yellow LED lights up. Red means: too hot or too cold. It is also possible to visualise relative humidity via the LEDs. The measured temperature, relative humidity and ambient light level are available via Modbus RTU.
 
How to avoid condensation?
The output of this sensor can control an EC fan, an AC fan speed controller or a damper actuator. The output value varies proportionally in function of the measured temperature and relative humidity.
E.g. if relative humidity increases, the sensor will increase the fan speed or open the damper.
 
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. 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.
 
Easy to use!
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 different ranges and the light intensity of the LEDs for status indication are adjustable. The Modbus register map provides a complete overview of all adjustable settings.
 
High quality
This HVAC transmitter is manufactured in Europe. 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. 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.
