ABB EIB / KNX Air Quality Sensor, SM
Accurately measures the CO2 concentration, humidity and temperature in a room. Three independent thresholds can be set for the CO2 concentration and the relative humidity in addition to a threshold for the temperature.
The following functions can be set:
Measured values can be transmitted directly on the bus.
Three independent programmable thresholds for CO2 concentration and relative humidity.
A threshold for the temperature.
Exceeding or under-shooting (under-running) the thresholds can trigger an action, e.g. sending, switching, value or priority.
Display of the achieved CO2 concentration and relative humidity via a four-colour LED on the sensor. CO2 adjustment range from 500…2550 ppm (threshold).
Relative humidity adjustment range from 1…100 %.
Temperature adjustment range 0…40 °C.
A separate communication object Lock threshold x CO2 (x = 1, 2 or 3) is available for every threshold.
The communication object Ventilation can be used for speed control or as a position indicator for ventilation flaps.
