Product description
This smart room sensor offers comprehensive HVAC control by measuring ambient light, relative humidity, and temperature.
lt measures temperature (0-50 °C) and relative humidity (0-95% rH). Based on the measured values, its single analog output controls devices like fans or dampers.
The sensor includes adjustable temperature/humidity ranges and an ambient light sensor.
It provides humidity and temperature-dependent fan speed control.
It is suitable for both flush-mounted and surface-mounted installation and connects easily with spring-contact terminal blocks.
It operates on 24 V DC.
All data is accessible via Modbus RTU, and the firmware can be updated.
It features LED status indicators with adjustable light intensity.
It offers long-term stability and accuracy.
This sensor is ideal for use in sensitive areas such as data centers and museums.
Additional specifications and description
What Values Does the Sensor Measure, and How Do the LED Indicators Work?
The temperature, relative humidity, and ambient light level are all measured by this HVAC transmitter. The green, yellow, and red LEDs provide a clear visual indication of the temperature. The green LED indicates that the temperature lies within the preset measurement range. The yellow LED illuminates when the temperature enters the alert range. Red denotes extreme heat or cold. The LEDs can also be used to display relative humidity. Modbus RTU communication provides access to the measured temperature, relative humidity, and ambient light level.

Which Devices Does the Sensor Control, and How Does It Operate?
This sensor's output can control an EC fan, an AC fan speed controller, or a damper actuator. The output value varies in direct proportion to the measured temperature and relative humidity.
For example, if relative humidity rises, the sensor will increase fan speed or open the damper.

How Are the Sensor's Wiring and Power Connection Made?
The cage clamp terminal blocks simplify wiring and installation. They eliminate the need for routine maintenance and ensure a solid or stranded wire contact. This sensor can be powered by either 24 V DC or 24 V AC. It is designed for a three-wire connection. The output ground (GND) is internally connected to the supply voltage ground (V-). Make sure not to connect this common ground to any other DC-powered devices.
What Is the Sensor Enclosure's Protection Rating, and How Is It Mounted?
The sensor enclosure is dust and moisture resistant to IP30 standards. It can be wall-mounted or built into a standard European wall mounting box. In the latter case, only the sensor's front plate will be visible on the wall.There is only little configuration necessary for this sensor. It can be almost directly used once it has been installed. Temperature and relative humidity are often region- and seasonal-specific. These parameters are still set to the correct values during installation. The other default settings are probably suitable for most applications. However, if necessary, they can also be adjusted via the respective Modbus registers. 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. The light levels of the LEDs used for status indication are also adjustable. The Modbus register directory provides a complete list of all programmable settings.
What Is the Sensor's Manufacturing Quality, Calibration, and Reliability?
This HVAC transmitter was made in Europe. In our factory, each sensor is calibrated and tested. We use high-quality sensor elements and components. This ensures the HVAC transmitter's long-term stability and accuracy.
