KNX CO2 sensor humidity Control + RTC System 55 pure white matt
Product code:
2104 27
CO2 sensor with an with integrated KNX bus coupler and two binary inputs, for measuring concentration of carbon dioxide, relative humidity and room temperature.
Description
Features:
- Limit value monitoring for CO2 concentration and humidity
- Dewpoint alert for e.g. cooling ceilings and winter gardens to prevent possible mould growth
- Two binary inputs for connection of zero-voltage contacts
- Logic gates for simple linking functions
- The CO2 sensor has no operating or display elements
Sensors:
- CO2 max. 4 different limit values can be set
- Adaptation to current sea level above NN
- Humidity sensor max. 2 limit values
Controller:
- 5 operating modes: Comfort, standby, night, frost/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/cooling units Controller can be de-activated (dew-point 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 limiting
- Switching function: two independent switching objects for each input present and can be enabled individually, command for rising or falling edge can be set independently (ON, OFF, CHANGE, no reaction)
- Dimming function: single 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 dge(nofunction, UP, DOWN, SW), operating concept can be parameterised, time between short and long-time operation adjustable, slat adjustment time adjustable
- Value transmitter and light scene auxiliary unit function: edge (push button as NO contact, push 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
