Gira 210401 CO -FT Sensor KNX System 55 Cream white

KNX CO2 sensor with humidity and room temperature controller System 55 Cream white glossy CO sensor with an integrated KNX bus connection and two binary inputs for measuring the 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 conservatories, 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, stand-by, 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.
Preset control parameters for common heating or cooling elements.
Controller can be switched off (dew point operation) or controller or operation of the controller can be locked.
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 switching, dimming, blind and value transmitter functions to the inputs.
Locking object for locking individual inputs.
Behavior when bus voltage returns can be parameterized.
Telegram rate limitation.
Switching function: two independent switching objects available for each input and can be enabled individually, command can be set independently on rising and falling edges (ON, OFF, TOGGLE, no reaction).
Dimming function: single-surface and double-surface operation, time between dimming and switching and dimming step size can be set, telegram repetition and stop telegram can be sent.
Blind function: command can be set on rising edges (no function, UP, DOWN, TOGGLE), operating concept can be parameterized, time between short and long operation can be set, slat adjustment time can be set.
Value transmitter and light scene extension function: edge (button as Normally open contact, button as normally closed contact, switch) and value on edge can be parameterized, value adjustment on button via long button press for value transmitter possible, light scene extension with or without memory function.

Notes:
The CO2 sensor has no operating or display elements.
When connecting the external inputs, the use of a switch terminal box is recommended.
No separate bus coupler is required to operate the CO2 sensor.
