GIRA CO2 sensor with humidity/room thermostat pure white glossy KNX UP

• Measurement range:
- CO2 concentration: 0 to 2000 ppm
- 0 to 2000 ppm: 10 to 95% rel. humidity
• Integrated KNX bus coupler and two binary inputs for measuring the carbon dioxide concentration, relative humidity and room temperature

• Cable length inputs: max. 5 m
• Protection class: III
• Installation depth: 23 mm
• Ambient temperature: 0 ... +45°C
• Limit value monitoring for CO2 concentration and humidity
• Dew point alarm for e.g. cooling ceilings and conservatories to prevent possible mould formation
• Two binary inputs for connection of floating contacts
• Logic gate for simple linking functions
• When connecting the external inputs, use of a switch terminal box is recommended
• No separate bus coupler required
• No controls or displays

Sensor:
• Max. four different limit values can be set
• Adjustment to current location height above sea level
• Max. two different limit values can be set

Controller:
• 5 operating modes: comfort, stand-by, night, frost or 5 operating modes: comfort, stand-by, night, frost or heating/cooling functions: heating, cooling, heating and cooling, basic and additional heating, basic and additional cooling
• Pre-set control parameters for standard radiators and cooling units
• Controller can be switched off (dew point mode) or the controller or controller interface can be locked
• Valve protection function (valve is opened in a 24-hour cycle)
• 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 on return of bus voltage can be parameterised
• Telegram rate limitation
