![CDATA[CO2 sensor with humidity and room temperature controller for KNX Pure white glossy CO₂ sensor with an integrated KNX bus connection and two binary inputs for measuring carbon dioxide concentration, relative humidity and room temperature. Features: Limit value monitoring for CO2 concentration and humidity. Dew point alarm for e.g. cooling ceilings and winter gardens, to prevent possible mold formation. Two binary inputs for connecting potential-free contacts. Logic gate for simple linking functions. Sensor: A maximum of four different limit values can be set for the CO2 sensor. Adaptation to the current local altitude above sea level. A maximum of two limit values can be set for the humidity sensor. Controller: 5 operating modes: comfort, standby, night, frost or heat protection and controller lock (e.g. dew point operation). Heating and cooling functions: heating, cooling, heating and cooling, basic and additional heating, basic and additional cooling.]]>
