Presence detectors also provide the capability of controlling heating, ventilation, air-conditioning in relation to whether or not persons are present. This makes a lot of sense from an energy point of view as it can save large quantities of it: If nobody’s there, why keep the heating on all the time. Yet, gradually, another aspect’s creeping into the focus of discussion: air quality or the content of CO2 ( Carbon Dioxide ) in room air. Ventilation systems require energy and the air that’s exchanged needs either heating or cooling. But the mere presence of persons is not enough for air to be exchanged through a ventilation system or automatically controlled window. What’s important is the quality of air. People inhale O2 and exhale CO2. This is a situation everyone’s familiar with: as the meeting wears on, concentration lapses and, at some point everybody’s tired, and later on people start to get a headache. The reason for this is the content of CO2 in room air. Unfortunately, this is something people only notice when it’s far too late to remedy the situation and actively provide ventilation. This is where Air Control sensor comes in – because it measures the amount of CO2 that’s present in room air. AC PRO Signal * Air-quality sensor matching presence detector * High energy-saving potential from on-demand ventilation * Automatic, maintenance-free CO2 measurement * Controls air-conditioning (ventilation, window opening, co-ordinated heating control etc.) * Provides information on air quality and the need for fresh air (visually and acoustically) * Also suitable for retrofi tting in training, conference, classrooms, offi ces and the home * Acoustic warning every 5 min. above ***0 ppm (can be deactivated) * Self-calibrating (to fresh air and air pressure/altitude) * Indicator with 3 LED’s (green, amber, red) Green: < ***0 ppm (light ‘ON’ permanently, can be switched ‘OFF’) Orange:***0 ppm – ***0 ppm
