CO₂ sensor humidity cont. + RTC KNX Gira F100 p.white

CO2 sensor with humidity and room temperature controller for KNX pure white glossy CO₂-sensor with an integrated KNX bus coupler and two binary inputs for measuring the concentration of carbon dioxide, relative humidity, and room temperature. Features: Limit value monitoring for CO2 concentration and humidity Dewpoint alert e.g. for cooling ceilings and winter gardens to prevent possible mould growth. Two binary inputs for connecting zero-voltage contacts. Logic gates for easy linking functions. Sensor: Up to four different limits can be set for the CO2-sensor. Adaptation to current sea level above NN. Up to two limits can be set for the humidity sensor. Controller: 5 operating modes: Komfort, standby, night, frost or heat protection, and controller lock-out (e.g. dew-point mode). Heating cooling functions: Heating, cooling, heating and cooling, basic and additional heating, basic and additional cooling. Preset control parameters for common radiators or cooling units. Controller deactivatable (dewpoint operation) or controller or operation of the controller can be blocked. Valve protection function (valve is opened cyclically every 24 hours). Control types: continuous PI control, switching PI control (PWM), and switching 2-point control (on off). Inputs: Free assignment of the functions switching, dimming, blind and value transmitter to the inputs. Blocker for blocking individual inputs. Behaviour can be configured following bus voltage recovery. Telegram rate limit. Switching function: two independent switching objects are available for each existing input and can be enabled individually, command for leading and trailing edge can be set independently (ON, OFF, CHANGE, no reaction). Dimming function: single-surface and double-surface operation, time between dimming and switching, and dim-step size can be set, telegram repetition and stop telegram transmission possible. Blind function: command can be set with rising edge (no function, UP, DOWN, SW), operating concept can be parameterised, time between short and long-term operation adjustable, slat adjustment time adjustable. Value transmitter and light scene auxiliary unit function: edge (button as NO contact, button as NC contact, switch) and value with edge can be configured, value adjustment by pressing and holding a button for value transmitters possible, light scene auxiliary unit with without memory function. Notes : The CO2-sensor does not have any operating or display elements. The use of a switch terminal box for connection of the external inputs is recommended. A separate bus coupler is not required to operate the CO2-sensor.
