Description
Built-in advanced iVOC sensor is sensitive to volatile organic substances typically contained in the stuffy air – gaseous metabolic products of human bodies and other gaseous pollutants such as formaldehyde, cooking vapors, fumes from paints, varnishes, adhesives, detergents, etc. that CO2 sensor does not detect. NL-iVOC sensor detects gaseous pollutant substances in the air that are the main reason for ventilation.
Sensor NL-iVOC approximates to human perception of air quality. The output of the sensor is calibrated as equivalent to a standard CO2 sensor. Measurement of the relative humidity is based on the principle of capacitive polymer sensor. The sensor has built-in two separate analog outputs – one for the actual concentration of VOC and the other for the current relative humidity. If the sensor contains 2 relays can be set two switching modes: standard (always one relay switched according to one quantity), a cascade mode (according to a selected quantity switch two relays with different levels of switching). Cascade switching, for example, can be used to switch power air conditioning units. The two rotary switches can be independently set the level at which the corresponding relay switches. Sensor can efficiently manage ventilation and heat recovery units, based on current air quality. By three LED indicators can be easily checked the current air quality. Preferred eco level means good indoor air quality needed to achieve a sense of well-being and at the same time can reduce energy costs for heating or air conditioning.
