Intelligent temperature / humidity sensor, 24 VAC - VDC

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.

Easy to connect! This temperature and humidity transmitter requires 24 VAC -VDC supply voltage - no need for an external power supply. The cage clamp terminal blocks reduce wiring and installation time. They eliminate the need for routine maintenance and guarantee a reliable contact for solid or stranded wires.

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, 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.

Room temperature humidity controller with single output. The supply voltage is 24 VAC or 24 VDC. It measures temperature, relative humidity and ambient light level. Based on the measured values, the dew point is calculated. The sensor algorithm controls the single analogue output based on the measured values. This single output can be used to directly control an EC fan, an AC fan speed controller or a damper actuator. The default output type is 0-10 V. Different output types can be selected. 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.
