Temperature | humidity controller wall mounting | 24 V DC - PoM
Product description
Single-output room temperature and humidity controller. The supply voltage is 24 V DC. It measures temperature, relative humidity, and the ambient light level. The dew point is calculated using the measured values for temperature and humidity. Based on the measured values, the sensor algorithm controls the single analogue output. This single output can control an EC fan, an AC fan speed controller, or a damper actuator directly.
The following output types are available: 0-10 VDC / 0-20 mA / 0-100% PWM. Modbus RTU provides access to all measurements and the output value. The power supply can be connected either through the terminal blocks or through the RJ45 connector. The ambient light sensor can be used in many applications to control the ventilation system based on occupancy.
Additional specifications and description
Is the temperature comfortable?
The green, yellow, and red LEDs on this HVAC sensor controller provide a clear visual indication of the temperature. The green LED indicates that the temperature is within the acceptable 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 provides access to the measured temperature, relative humidity, and ambient light level. 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.

4-wire connection
You can connect this sensor using either the cage clamp terminal blocks or the RJ45 connector. The RJ45 connector can be used to connect power and Modbus RTU communication. The outputs, Modbus RTU communication, and supply voltage can all be connected using the terminal blocks. Never connect the supply voltage through the RJ45 connector and the terminal blocks at the same time. The supply voltage is 24 V DC. The ground terminals of the power supply (V-) and output (GND) are not connected internally. This means that connecting this sensor will necessitate the use of a 4-wire cable. Most 24 V DC power supplies include short-circuit, overload, and overvoltage protection. A supply voltage of 24 V DC improves the safety and reliability of your installation. 
This sensor requires only little configuration. Once installed, it is almost ready to use. Temperature and relative humidity are frequently affected by region and season. These parameters are still set to the correct values during installation. The other default settings, on the other hand, will work with the majority of applications. They can still be changed if necessary by adjusting the corresponding Modbus registers. To make the sensor compatible with other devices, for example, a different output type can be selected: 0-10 VDC, 0-20 mA, 0-100% PWM, and Modbus RTU. The brightness of the LEDs used for status indication can also be adjusted. The Modbus register map provides an exhaustive list of all programmable settings.
Superior quality
This HVAC sensor controller 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 controller's long-term stability and accuracy. The enclosure meets IP30 dust and moisture resistance standards and can be mounted on a wall or flat surface indoors. To ensure peak performance, keep it out of direct sunlight.
