C02 dependent<br />
ventilation control<br />
Fig. 1<br />
Fig. 2<br />
Fully-automatic ventilation control via integrated, patented<br />
C02 sensors.<br />
The optoelectronic sensor is completely maintenance-free and does<br />
not have to be cleaned regularly.<br />
Sensor:<br />
• With LED display for CO2 concentration<br />
• CO2 output 0-10 V (0-2000 ppm)<br />
• Room temperature output 0-10 V (0-40 °C)<br />
• Humidity-dependent output 0-10 V (20-100 % humidity) (fig. 1)<br />
Control board:<br />
• OpenTherm interface (optional)<br />
• Input for temperature sensor NTC (frost protection)<br />
• 0-10 V input for CO2 sensor/hygrostat<br />
• 230 V output e. g. for bypass louver<br />
• Operating display/error display (floating contact)<br />
• Volumetric flow can be set for 3 stages<br />
• Control of fans via 0-10 V output<br />
• Fan monitoring via evaluation of tacho signal<br />
• Input for safety contact for all pole separation of fan motors (e. g.<br />
door contact, pressure switch etc.)<br />
• Timer for filter change display
