Minimum and maximum values
Using a display & programming module OPA-S, the user has the option to read out and reset the CO2 and temperature
minimum and maximum values. The minimum and maximum values may as well be used as output signals. The minimum
and maximum values are automatically saved to the device and are available after a power interruption.
For OPA-S usage see section "Displaying minimum and maximum values" on page 5.
Indication of air quality (CO2 concentration)
Three color LEDs are used to indicate air quality: Green for low CO2 concentration, orange for medium and red for high
concentration. The levels for low-medium-high may be programmed.
