Product description

Measures Multiple Parameters: It measures temperature, relative humidity, air quality (TVOC), and ambient light level.

Single-Output Control: The device's algorithm uses these measurements to control a single output for managing an EC fan, AC fan speed controller, or damper actuator.

Flexible Power and Communication: It operates on a 24 VDC supply and uses Modbus RTU communication for all data and settings.

Adjustable Output Type: The output signal can be adjusted to various types, with a default of 0-10 V.

Customizable Settings: All settings, including the light intensity of the status LEDs, can be easily adjusted via Modbus RTU.

Replaceable Sensor: The TVOC sensor element is replaceable, ensuring long-term use.

Occupancy-Based Control: The ambient light sensor can be used to control the ventilation system based on room occupancy.

Additional specifications and description

  
What is TVOC and How Does the Sensor Indicate Air Quality?
TVOC or Total Volatile Organic Compounds evaporate from substances such as cleaning products, adhesives, paints, etc. TVOCs are also emitted from humans and animals. That is why a TVOC sensor provides a good, overall image of air quality. TVOC sensors are the best choice to control a ventilation system in residential environments. This HVAC transmitter offers a clear, visual indication of the air quality via the green, yellow and red LED. The green LED indicates that the TVOC level is within range - there is sufficient fresh air supply. When the TVOC level enters the alert range, the yellow LED lights up. Red means: TVOC out of range or insufficient fresh air supply. The measured temperature, relative humidity, TVOC and ambient light level are available via Modbus RTU communication.
  
What Values Does the Sensor Measure and How Does It Control the HVAC System?
This sensor measures temperature, relative humidity and air quality (TVOC). It has one analogue output. The sensor algorithm regulates the output value to keep the measured values within range. 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, humidity and TVOC concentration. When more fresh air is required, the sensor will increase the fan speed or open the damper.
  
What Are the Sensor's Power Supply and Wiring Requirements?
The supply voltage is 24 VDC. The ground terminals of the power supply (V-) and output (GND) are internally not connected. This means that a 4-wire cable is required to connect this sensor. Most 24 VDC power supplies offer protection against short circuit, overload and overvoltage. A 24 VDC supply voltage increases the safety and reliability of your installation
  
Is Programming Required for the Sensor's Installation and Settings?
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, a different output type can be selected to make it compatible with other devices: 0-10 VDC / 0-20 mA / 0-100 % PWM / 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.
  
How Are the Sensor's Calibration, Durability, and Mounting Performed?
Each sensor is calibrated and tested in our factory. In the unlikely event of TVOC 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.
