Temperature | humidity controller flush mounting | 24 V AC - V DC
Product description
Temperature, relative humidity, and ambient light levels are measured by this room sensor. The distinctive enclosure supports surface or flush mounting. The supply voltage is 24 V AC or 24 V DC. The sensor algorithm controls the single analogue output, based on the measured values. The output can directly control an EC fan, an AC fan speed controller, or a damper actuator. The output format itself is selectable.
Through Modbus RTU, all measurements and the output value are accessible and all settings can be adjusted. The LEDs used for status indication also have an adjustable light level.
The ambient light sensor can be used in many applications to regulate the ventilation system depending on how many people are in the room. This HVAC sensor is frequently used to regulate humidity and temperature in data centers, museums, libraries, wine cellars, etc.
Additional specifications and description
Is the temperature comfortable?
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.

How can condensation be avoided?
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.

Easy to connect
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.
Flush mounting or surface mounting
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.
High quality
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.
