CO | NO2 controller | flush mounting | LED indicators, 24 VDC


Product description

Multifunctional room sensor to measure temperature, relative humidity, CO, NO2 and ambient light. The unique enclosure allows flush mounting or surface mounting. The supply voltage is 24 VDC. 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 output type can be selected. All measurements and the output value are available via Modbus RTU. The CO - NO2 sensor element is replaceable. All settings can be adjusted via Modbus RTU. Also the light intensity of the LEDs for status indication is adjustable.

Additional specifications and description

 
Is there sufficient fresh air supply?
This HVAC transmitter offers a clear, visual indication of the CO level via the green, yellow and red LED. The green LED indicates that the CO level is within range - there is sufficient fresh air supply. When the CO level enters the alert range, the yellow LED lights up. Red means: CO out of range or insufficient fresh air supply. The LED indicators can also indicate one of the other measured values. The measured temperature, relative humidity, CO, NO2,  dew point and ambient light level are available via Modbus RTU.
 
How to control fresh air supply?
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 CO concentration. When more fresh air is required, the sensor will increase the fan speed or open the damper.
 
Easy to connect!
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. 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.
 
Flush mounting What is flush mounting
This sensor can be mounted on a wall, a flat surface or in a standard European wall mounting box. Only the front plate of the sensor is then visible on the wall - the sensor is flush mounted. 
 
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.
 
The best quality and reliability
This HVAC sensor is manufactured in Europe. Each sensor is calibrated and tested in our factory. In the unlikely event of CO - NO2 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.
